xviii Eclipse™ 2640 SAN Router Administration and Configuration Manual
1 Overview This chapter provides an introduction to the EclipseTM 2640 SAN Router. Use the following links to move through this chapter.
Introduction 1 Introduction The Eclipse 2640 SAN Router (referred to as SAN Router in this manual) supports iSCSI, iFCP, and R_Port for trunking to both Internet Protocol (IP) backbones and legacy Fibre Channel (FC) fabrics. The SAN Routers connect to a wide range of end systems, including Fibre Channel, NAS, and iSCSI initiators and targets. SAN Routers support Ethernet and Fibre Channel switching over extended distances at wire speed.
Introduction 1 Figure 1-1 Eclipse 2640 SAN Router Two management ports are located on the front of the SAN Router. An RS-232 serial port can connect to a VT100 or terminal emulator for access to the Command Line Interface (CLI), and an RJ45 port can connect to the LAN for out-of-band management through the SAN Router Element Manager and SANvergence Manager. The RJ45 management port can be accessed by any workstation on the LAN using http, Telnet, and SNMP for management.
SAN Router Features 1 SAN Router Features The Eclipse 2640 SAN Router features are summarized in the following table. Table 1-1 1-4 Eclipse 2640 SAN Router Features Feature Description Intelligent Ports The SAN Router supports two types of ports - standard ports and intelligent ports. A standard port can be configured for Fibre Channel traffic. An intelligent port can be configured for Ethernet port Internet Small Computer Systems Interface (iSCSI) or Internet Fibre Channel Protocol (iFCP).
SAN Router Features 1 Table 1-1 Eclipse 2640 SAN Router Features (Continued) Feature Description Real-time and historical system logs The Element Manager and Log Viewer can be used to look at current system log messages from the connected SAN Router. Compression Compression technology available on intelligent ports identifies repetitive patterns in a data stream and represents the same information in a more compact and efficient manner.
SAN Router Layout 1 SAN Router Layout The SAN Router front panel (Figure 1-2 on page 1-6) provides an Ethernet LAN connector (10/100), small form-factor pluggable (SFP) connectors port status LEDs, and a green system (SYS) LED. The panel also provides a 9-pin DSUB maintenance port (CONSOLE) for connection to a local terminal or remote terminal. The maintenance port provides an alternate way to configure the SAN Router in addition to the normal http scenario.
2 Configuring System Basics This chapter provides steps for configuring the SAN Router’s basic functions before performing specific configuration for various network connections. Use the following links to move through the chapter.
Configuring the SAN Router 2 Configuring the SAN Router You can configure the SAN Router using any of the three options as follows: • Command Line Interface (CLI). For this method a VT100 terminal or PC with terminal emulation software running must be connected to the RS-232 serial port on the SAN Router. • SAN Router Element Manager.
Setting Parameters Through the CLI 2 management workstations in different networks, then multiple routes may need to be configured. Unlike other configuration parameters, when the SAN Router is reset to factory defaults, the IP address of the management port is retained. This prevents administrators from locking themselves out of the SAN Router, requiring console connectivity to reset the management port IP address. If the SAN Router is shipped in a cabinet, then the default IP address will be 10.xx.yy.
Setting Parameters Through the CLI 2 Parameter Setting Bits per second 9600 Data bits 8 Parity bits None Stop bits 1 Flow Control None 3. Power up the terminal. Press the Enter key to display the CLI prompt. 4. Type modify at the Access Mode prompt. This is case-sensitive. Read is for read-only; modify is for read-write. 5. Type your password at the Password (community string) prompt. Use private as the password and press Enter. 6.
Using the Element Manager 2 9. Reset the system using the following command: reset system The management IP address is now set and ready for normal operation. 10. If you require a terminal connection to the 10/100 port for out-of-band management, connect the standard RJ45 Cat 5 Ethernet cable from the LAN to the management port. 11. Ping the IP address that you entered for the SAN Router to verify network connectivity using the network management host.

Tips on using the Element Manager 2 CAUTION Only one user at a time should be allowed to login with read and write privileges so as not to write over each other’s changes. Granting Clipboard Access for Copy and Paste Element Manager is an unsigned JavaTM applet. As such, default security settings prevent it from using the system clipboard. This means that you cannot copy and paste text between Element Manager text fields and other applications.
Tips on using the Element Manager 2 NOTE: Alternatively, for either operating system, you may instead edit the.java.policy file (note different name, with period in front) in the user's home directory. For Windows XP, the directory would be C:\Documents and Settings\. To grant clipboard access, follow these instructions: 1. Add the following lines at the beginning or end of the policy file to enable clipboard access for ALL Java applets: grant {permission java.awt.
Tips on using the Element Manager 2 1. Select Internet Options under the Tools menu in Microsoft® Internet Explorer. 2. Click the Advanced tab. 3. Under Browsing, disable Enable third-party browser extensions, if enabled. 4. Restart your computer. The Windows XP Service Pack 2 provides the ability to individually enable or disable an extension (now called an add-on) in Internet Explorer without entirely disabling third-party extension support. The FireFox 1.0 browser also supports this feature.
Configuring IP Addresses 2 Configuring IP Addresses SAN Routers use the iFCP and iSCSI protocols, which use IP addresses for all routing and forwarding of storage traffic. Using the iFCP/iSCSI protocol, all Fibre Channel addresses are mapped to one or more IP addresses. You must configure two IP addresses with SAN Routers: the external iFCP/iSCSI network and the IP network. When sending storage traffic to the external network, SAN Routers uses the “external” IP addresses associated with the TCP ports.
Configuring IP Addresses 2 Figure 2-5 Internal and External IP Addresses A SAN Router has iFCP/iSCSI ports that are connected to the external IP network, and one or more ports that are connected to the internal IP network. Each TCP port connects to each network (both the internal and external networks) as an independent device. The TCP port uses the iFCP/iSCSI IP address to talk to the external network and the internal IP network IP address to talk to the internal network.
Configuring IP Addresses 2 The Figure 2-5 shows the role and position of each IP address relative to the internal and external IP networks. The Router Inband IP Address The router inband IP address is used for the internal delivery of storage traffic. To configure the SAN Router inband address, use Configuration>System>Inband Address in the Element Manager.
Configuring IP Addresses 2 Figure 2-7 FC/Ethernet Port Configuration Dialog Box The Next Hop Gateway IP Address The iFCP/iSCSI ports interact with the external IP network as if they were independent IP hosts. Each iFCP/iSCSI port needs a gateway address of an external router that can forward the storage traffic to the remote iFCP/iSCSI port. This Next Hop Gateway Address is the first-hop gateway address.
Configuring IP Addresses 2 The Internal IP Address Storage traffic that is to be transported through the external network by iFCP or iSCSI must first be delivered to the iFCP/iSCSI port that will perform the iFCP/iSCSI encapsulation. The internal IP address is used by the iFCP/iSCSI port to receive this storage traffic from the internal network. This traffic is then re-addressed and re-encapsulated into an iFCP/iSCSI connection that traverses the external network.
Configuring IP Addresses 2 Figure 2-8 FC/Ethernet Port Configuration Dialog Box Guidelines When Working with Firewalls The iFCP and iSCSI protocols use TCP for transmission. TCP provides several benefits such as: • Retransmission of any packets dropped by the network. • Guaranteed in-order delivery. • Fields that are leveraged by firewall devices for added security. Prior to transmitting data, TCP must first establish a connection between the TCP sender and the TCP receiver.
Configuring IP Addresses 2 connection is established are the TCP segments allowed to be transmitted from the sender to the receiver. A firewall can be used to block the establishment of TCP for some applications while permitting other applications to transmit data. To accomplish this, firewalls frequently use a combination of TCP port numbers and IP addresses. Port numbers are used to identify the sending and receiving application.
Configuring IP Addresses 2 • Ping operation results (37010) The following datapath ports must be open if you want to manage across a firewall using SANvergence Manager: 2-22 • SNMP Protocol (161) • SNMP Traps (162) Eclipse™ 2640 SAN Router Administration and Configuration Manual

This saves the currently running configuration to flash memory. Setting the SAN Routing Cluster ID The R_Port SAN Routing Cluster ID is used by the SAN Router R_Ports to register a unique virtual node WWN to the connected fabrics. Third-party management applications use this WWN to manage the SAN Router.
Configuring System Operations 2 The values set take effect only after the SAN Router R_Ports are disabled and enabled (re-initialized). NOTE: Changing the cluster ID changes the registered virtual switch node WWN. This may require the management applications to re-discover the SAN Router. To set the cluster ID, follow these instructions: Procedure 1. Select Configuration>System>Operations to display the System Operations dialog box. Figure 2-11 System Operations Dialog Box 2.
Configuring System Operations 2 Configuring System Date and Time To configure the system date and time from the SAN Router’s clock and configure Simple Network Time Protocol (SNTP), follow these instructions: 1. Select Configuration>System>Date/Time to display the Date/Time dialog box. The Date/Time dialog box displays the current date and time from the SAN Router’s clock as shown in Figure 2-12. Figure 2-12 Date/Time Dialog Box 2. Select the SNTP operating mode for the SAN Router’s internal clock.
Configuring System Operations 2 SAN Router Time Zone - Select a time zone from the drop-down list. Daylight Savings Time - Select On or Off from the drop-down list if daylight savings time pertains to your time zone. The SAN Router does not automatically change this setting when daylight savings time begins or ends. You must update this setting manually. • SNTP Server - Select this mode to set the SAN Router as an SNTP server.
Configuring System Operations 2 Configuring the Router Inband Address To configure the SAN Router’s internal “router inband” address through the Element Manager, follow these instructions: 1. Select Configuration>System>Inband Address to display the Inband Address Configuration dialog box (Figure 2-13). Figure 2-13 Inband Address Configuration Dialog Box 2. Type the new IP address. 3.

Choose Save Configuration from the File tab to permanently save your changes to the runtime configuration.
Configuring System Operations 2 Configuring mSNS The SAN Router’s metro storage name server (mSNS) stores the inventory of hosts and storage devices in the mSAN as well as zoning information, to specify which hosts can use which storage devices. SAN Router discovers the Inventory information automatically. You can view inventory information for locally attached devices by selecting Storage Name Server from the Statistics/Info tab. For more information, refer to Viewing Statistics on page 6-14.
Static Routes 2 3. Click Place in a default router zone (zone 1) to place all new devices in the default zone (zone 1) where they can communicate with each other. 4. Click OK. 5. Choose Save Configuration from the File tab to permanently save your changes to the runtime configuration. This saves the currently running configuration to flash memory. Static Routes Static routes are used to route non-storage payload traffic, such as management traffic or RADIUS.
Static Routes 2 If the SAN Router is responding to an IP packet that originated from, for example, the SNMP management station on 10.1.4.2, then it needs to be told to route the response over the management port to the SAN Router 10.1.3.1. Static routes are used for this purpose. An entry is made in the static route table telling the SAN Router to route all traffic destined to 10.1.4.1 (the IP mask is included to define a range of addresses) to the next hop SAN Router, 10.1.3.1.
Static Routes 2 Figure 2-19 Static Routing Configuration Dialog Box NOTE: Use the lower portion of this dialog box to create a permanent static route to the subnet where your management workstation(s) reside. For more information, refer to Configuring the Management Port on page 2-9. • Destination IP is the IP address of the destination subnetwork. • Destination IP Mask is the subnet mask of the destination subnetwork.
Static Routes 2 status is Added Not Applied and the row is green. If you select an entry to be removed, the entry status is Removed Not Applied and the row is red. Important Notes for Static Routes If the SAN Router is to be managed from a single external subnet, follow the directions under Static Routes. There are two ways to manage an SAN Router if different management stations reside in different subnets. 1. Define static routes for each management subnet as described in Static Routes. 2.

3 Configuring RADs and mSAN Connections This chapter provides steps for configuring the SAN Router and its Fibre Channel ports for attaching directly to Fibre Channel devices, such as servers and storage. Use the following links to move through the chapter.
Introduction 3 Introduction You can configure the SAN Router ports for connecting to Fibre Channel devices directly attached to the SAN Router. These devices, such as servers and storage devices, are called router-attached devices (RADs). You can also configure the R_Port to attach to fabrics that are interconnected by one or more SAN Routers. R_Port is a fabric extension port used to establish inter-switch links (ISLs) between a SAN Router and Fibre Channel switches.
Introduction 3 • To directly attach a SAN Router to an Fibre Channel switch, configure the ports 1-12 as a R_Ports. For details, refer to Configuring R_Ports for mSANs on page 3-6. • Configuring and Managing Zones in R_Port Connected Networks - SANvergence Manager Version 4.7 or higher is required to manage zones for R_Port connected networks. For detailed information on R_Port zone management, refer to the SANvergence Manager User Manual.
Configuring the FC Ports for Router-Attached Devices 3 Configuring the FC Ports for Router-Attached Devices This section describes how to configure the Fibre Channel ports on the SAN Router as R_Ports for attaching directly to an Fibre Channel device. To configure R_Ports for attaching to an Fibre Channel switch (mSAN), refer to Configuring R_Ports for mSANs on page 3-6. 1. Select Configuration>Port>FC/Ethernet to display the FC/Ethernet Port Configuration dialog box (Figure 3-1 on page 3-4).

Port Speed: Click the Port Speed list and select either 1 Gigabit, 2 Gigabit, or Auto. For the SAN Router, default port speed is Auto. With this setting, the SAN Router automatically detects the speed supported by the connection and sets it appropriately. You can manually configure the port to 1 Gb/sec or 2 Gb/sec.
Configuring R_Ports for mSANs 3 Configuring R_Ports for mSANs The following procedure describes how to configure an Fibre Channel port as an R_Port to attach Fibre Channel devices and mSANs. 1. Perform steps 1 through 7 under Configuring the FC Ports for Router-Attached Devices on page 3-4. 2. In the FC/Ethernet Port Configuration dialog box, select R_Port in the FC Port Parameters section with the Port type. The configured R_Port parameters appear in the dialog box.
Configuring R_Ports for mSANs 3 Figure 3-2 FC/Ethernet Port Configuration Dialog Box Table 3-1 on page 3-8 describes the current R_Port parameters that may appear.
Configuring R_Ports for mSANs 3 Table 3-1 3-8 R_Port Parameters Parameter Description Role The values are Fabric Manager or Non-principal. When a new Fibre Channel switch is connected and introduced to an existing fabric through use of the R_Port, an election process is initiated to determine which switch in the new fabric shall be the principal switch. To avoid duplicates, the principal switch is responsible for assigning and coordinating allocation of Domain IDs to every other switch in the fabric.
Configuring R_Ports for mSANs 3 Table 3-1 R_Port Parameters (Continued) Parameter Description Zone policy Use SANvergence Manager to set this parameter. Options are Append Router Zones, and No Router Synch (Synchronization): Append Router Zones - The SAN Router Storage zone set is appended to the active zone set on the fabric connected by the R_Port. No Zone Synch - The zone set information between the mSAN and the fabric connected by the R_Port is not synchronized.
Configuring Advanced FC Port Parameters 3 Configuring Advanced FC Port Parameters To configure FC port timeouts, follow these instructions: 1. Select Configuration>Port >Advanced FC Port to display the Advanced FC Port Configuration dialog box. Figure 3-3 Advanced FC Port Configuration Dialog Box 2. Select the Port number from the list. The current timeout values are displayed and may not be changed. • EDTOV - (Error detection timeout value in seconds).
Example Configuration and Procedures 3 Example Configuration and Procedures This section provides a specific example of procedures to configure a SAN Router for a RAD, as well as an mSAN consisting of an Fibre Channel switch and attached storage (Figure 3-4). Figure 3-4 Connecting to Fabric and FC Device The configuration in Figure 3-4 on page 3-11 shows both the SAN Router and the Fibre Channel switch with no pre-configured zones.
Example Configuration and Procedures 3 3. Follow steps under Configuring the FC Ports for Router-Attached Devices on page 3-4 to configure port 3 for connecting to the FC server. Make sure to select FC-Auto under FC Port Parameters on the FC/Ethernet Port Configuration dialog box. 4. Follow steps under Configuring R_Ports for mSANs on page 3-6 to configure port 4 as an R_Port. 5. Make sure that the fabric timeout values E_D_TOV, R_A_TOV for both the mSAN and the fabric match.
Example Configuration and Procedures 3 As soon as the zone configuration is activated from SANvergence Manager (by clicking Commit), the zone set is also registered with the fabric zone server. Since you created the router zone set during the R_Port configuration process, the new zone set is also activated in the fabric. Configuration Notes for All R_Ports on the Same Fabric • E_D_TOV and R_A_TOV values must be the same. • Domain IDs must be different.

4 Configuring iSAN Connections This chapter provides detailed steps for configuring the SAN Router ports for iFCP and setting up iFCP connections. Use the following links to move through the chapter.
Introduction 4 Introduction An iSAN (internetworked storage area network) is a collection of one or more fabrics interconnected using one or more SAN Routers, where at least one fabric is in a distant location outside the metro area. An iSAN is characterized by high latency and low bandwidth inter-switch links (T1, T3, OC3, etc.) such as those found in wide area networks. An iSAN has at least two SAN Routers that are interconnected using iFCP connections. An iSAN is also a collection of two or more mSANs.
Introduction 4 Figure 4-1 iSAN Configuration Example Chapter 3 provides instructions for configuring the SAN Router to create an mSAN by attaching fabrics to the SAN Router R_Ports. Chapter 4 provides steps for interconnecting mSANs with remote mSANs over a WAN. Connections to the network are made through those SAN Router’s TCP ports available for configuring FC Protocol (iFCP) connections.
Configuring TCP Ports for iFCP 4 Configuring TCP Ports for iFCP This section describes how to configure the TCP ports (port numbers 13-16 on the Eclipse 2640 SAN Router) for iFCP connections. This involves the following procedures: • Setting the general port parameters • Setting advanced TCP parameters • Setting the iFCP parameters Configuring the General Port Parameters 1.
Configuring TCP Ports for iFCP 4 Figure 4-2 FC/Ethernet Port Configuration Dialog Box 2. Select a port. The screen is refreshed to show the operational state. 3. Type a label for this port in the Port Name field. 4. Set the port speed under the Port Speed list, if needed and select the Enable Port checkbox. 5. Select or clear the Autonegotiations check box as required.
Configuring TCP Ports for iFCP 4 6. Select the Flash LED option to blink the port LED. You can use this option to locate the physical port in a rack of SAN Routers. Setting the Advanced TCP Parameters The SAN Router provides options to optimize the TCP port behavior through a set of advanced parameters. Use the following procedure to configure the advanced TCP parameters. 1. Click the Advanced button. The Advanced TCP Configuration dialog box appears (Figure 4-3 on page 4-6).
Configuring TCP Ports for iFCP 4 Manual Reset: You may not want the auto-reset option to be on when you are troubleshooting unrecoverable errors. In this case, you can do a manual reset by clicking Reset Port in the FC/Ethernet Port Configuration dialog box. 2. Set the MTU size. The MTU (maximum transmission unit) size can be used to prevent accidental fragmentation when the path (discovered) MTU value, as returned by paths from/to this port, is incorrect.
Configuring TCP Ports for iFCP 4 1. Select Smaller CWND Reduction in Fast Recovery to improve the performance of the SAN Router when packet losses occur due to reordering or noise rather than congestion. When enabled, the SAN Router responds more slowly to congestion events because the send congestion window (CWND) is reduced to 7/8 of its previous value as compared to 1/2 in standard TCP. NOTE: Do not select this option when other traffic sources sharing the same TCP link are bursty or intermittent. 2.
Configuring TCP Ports for iFCP 4 6. Specify the number of ACKs that trigger Fast Retransmit or Fast Recovery using the Threshold field. Valid values are between 8 to 128, with a default of 8. Larger values reduce retransmissions by causing the SAN Router to wait longer for retransmitted packets to arrive. This may delay the detection of dropped packets. Setting the iFCP Parameters 1. To set the port as iFCP, select iFCP from the iFCP/iSCSI parameters field. 2. Specify the IP address.
Configuring TCP Ports for iFCP 4 Figure 4-4 Advanced TCP Configuration iFCP Parameter 1. Select the compression behavior for the TCP/IP port using the Compression Level combo box. Compression is an optional software feature; the Compression Level field is disabled if compression is not included in your software version. Compression technology takes advantage of replicated characters or patterns being sent across a network port to effectively increase throughput on that port.
Configuring TCP Ports for iFCP 4 • HW - All transmitted data is compressed using the hardware feature in the SAN router. This is the recommended setting if the remote destination also supports HW compression. • SW - All transmitted data is compressed, using the SAN router’s CPU. Use this setting when you need to use as little bandwidth as possible and the remote destination does not support hardware compression.
Configuring TCP Ports for iFCP 4 Select Hardware Compression from the Compression Level drop-down list. This has the lowest compression ratio, but it can run at link rate. 3. Select Selective ACKnowledgement (SACK) to acknowledge non-contiguous sequence numbers. This reduces the amount of retransmitted data when packets are lost. Enabling this provides better performance in congested networks (assuming the remote device also supports SACK). Setting FastWrite Features 1.
Configuring TCP Ports for iFCP 4 Router without a XFER_RDY from the target device. Specify the maximum amount of buffered data, in kilobytes, in the text field. The memory limit is a single pool for all Fabric Channel login sessions. • Selecting the Transmit Buffer Management option allows the user to manage the amount of Fabric Channel receive buffers that an iFCP port has for receiving the Fabric Channel frames forwarding from Fabric.
Configuring iFCP Connections 4 Configuring iFCP Connections To configure an iFCP connection, configure a TCP port (13-16) as iFCP, as described in Configuring TCP Ports for iFCP on page 4-4. A pair of SAN Routers connects two mSANs. Each mSAN is identified by a unique mSAN ID and each has its own mSNS. Only configure a mSAN ID when iFCP is being used. Otherwise, there is only a single mSAN.
Configuring iFCP Connections 4 • Set the local mSAN ID when the SAN Router is installed. The default value is zero (0). The local mSAN ID is a number between 0 and 4,294,967,295 that uniquely identifies the local mSAN. NOTE: The SAN Router at each end of the iFCP link (and thus the mSANs at each end) must have different mSAN IDs. Configure Remote iFCP Connections For each SAN Router, you must specify a list of the remote SAN Routers to which it should export zones.
Configuring iFCP Connections 4 Table 4-1 4-16 Read-Only Remote Connections Parameters Column Description Connection Indicates whether the connection is primary (manually configured on this SAN Router) or backup (automatically copied from this SAN Router or another SAN Router so the local SAN Router can back up the connection). From The connection port on the local SAN Router. If the port is not configured for iFCP, the remote connection will fail. To The connection destination in the remote SAN.
Configuring iFCP Connections 4 NOTE: Backup connections (identified by Backup in the Connection column) cannot be selected, even when the backup connection is active. Backup connections cannot be edited or removed. These connections inherit their settings from the corresponding primary connection. CAUTION When exporting zones across iFCP, make sure the zone members are device WWNs and not fabric ports, as fabric port zones are not supported across iFCP.
Configuring iFCP Connections 4 Figure 4-7 Add Remote Connection Dialog Box Use this dialog box to add new remote iFCP connections or edit parameters for existing connections. You can modify information in this dialog box as described in Table 4-2.
Configuring iFCP Connections 4 Table 4-2 Remote Connections Parameters Setting Description Connection Description Enter up to 32 characters of description to help remember the purpose of this connection. Local SAN Router Port Select the port on the local SAN Router from the drop-down list. Remote SAN Router IP Address IP address of the SAN Router that is providing TCP access to the remote SAN. Enter the remote SAN Routers WAN port address.
Configuring iFCP Connections 4 Figure 4-8 Edit Remote Connection Dialog Box NOTE: To select a range of connections, select the first, then hold down the Shift key while selecting the last connection. To select a set of connections, hold down the Ctrl key while clicking on each connection. 3. To remove iFCP connections, select one or more rows in the table and click Remove. Removing a remote connection terminates all data sessions to that SAN Router.
Configuring iFCP Connections 4 • A connection with a status of Down is enabled but inactive. The SAN Router periodically attempts to restore a failed connection. If you wish to initiate a reconnection attempt (for example, after you’ve corrected the cause of the connection failure), select the connection and click the Restart button. 5. Press F5 or click the Refresh button to refresh the list of remote connections, including their status information.
Configuring a Backup iFCP Connection 4 Configuring a Backup iFCP Connection You can configure redundant fail-over for the iFCP connection so that one iFCP port backs up another iFCP port on the same SAN Router. Redundant ports must be configured symmetrically; for example, each port must back up the other. A port can have both primary and backup connections, such as pair of ports having connections to a remote SAN, exporting different zones to split the load.
Configuring a Backup iFCP Connection 4 5. Set the Timeout for backup activation to between 5 and 60 seconds (default is 5 seconds). If the backup port cannot reach the primary port through the local SAN for this period of time, the backup port assumes that the primary port has failed and activates the redundant connection. This timeout does not apply if the primary port is running but the WAN link to the primary port goes down.
Example Configurations and Procedures 4 Example Configurations and Procedures This section provides procedures to configure the SAN Router for connecting remote SANs through iFCP. This section assumes that you have SANvergence Manager software installed. Figure 4-10 illustrates two SAN Routers connecting two FC disks across a TCP/IP metropolitan area network (MAN) or wide area network (WAN).
Example Configurations and Procedures 4 • If the WAN link is severed, separate mSNS servers allow continued undisturbed communication between initiators and targets within the local and remote sites. • When the WAN link is reconnected, communication between the local and remote devices is automatic and no fabric resets are necessary to reconverge the network. A simplified version of this is illustrated in Figure 4-11 on page 4-25.
Example Configurations and Procedures 4 2. Enter the default Modify password (private) in the field provided and click OK. 3. When the Element Manager window appears, select Configuration>System>Inband Address to change the SAN Router’s inband address parameters. • Set the inband address to 192.168.20.131. When you change the Inband IP address, you must reset the SAN Router before you can configure the iFCP port. • Leave the gateway at 0.0.0.0 and click OK. 4.
Example Configurations and Procedures 4 When you change the Inband IP address, you must reset the SAN Router before you can configure the iFCP port. 12. Select Configuration>Ports>FC/Ethernet when Element Manager displays the FC/Ethernet Port Configuration dialog box (Figure 4-12 on page 4-27). Figure 4-12 FC/Ethernet Port Configuration Dialog Box • Select port 13 for configuring a remote SAN /iFCP connection. • Select Enable Port.
Example Configurations and Procedures 4 • Select iFCP under iSCSI/iFCP Parameters and enter the following information: • Port IP- 192.168.27.130 • Subnet Mask- 255.255.255.0 • Next Hop Gateway Address: 0.0.0.0 • Internal address: 192.168.17.131 • Select OK. 13. Select Configuration>iFCP>Setup to display the iFCP Setup dialog box, and enter 130 for the Local mSAN ID. Click OK. 14. Select File>Save Configuration and click OK. 15.

5 Configuring iSCSI Connections This chapter provides procedures to configure the SAN Router to support line-rate communication between iSCSI initiators and Fibre Channel targets. Use the following links to move through the chapter.
Introduction 5 Introduction SAN Routers support true gigabit wire-speed iSCSI-FC gateway functionality, which means they can translate iSCSI traffic to Fibre Channel traffic and vice versa. Using SAN Routers, iSCSI initiators can access FC storage devices as shown in Figure 5-1. The initiators and targets (FC or iSCSI) can be either directly connected to the SAN Router or connected across an FC or IP network as shown.
Introduction 5 Figure 5-2 Example Configuration The server in Figure 5-2 can either be directly connected to the SAN Router or indirectly connected via an intermediate IP network. For a direct-attached configuration, the server must be physically connected to the iSCSI-capable ports (13-16) on the SAN Router. When connected via an intermediate IP network, the server must have IP connectivity to one of the TCP ports on the SAN Router.
Configuring iSCSI Ports 5 iSCSI Configuration Procedures To configure iSCSI communication with fabrics, follow these steps: 1. Configure the TCP ports for iSCSI. Follow the procedures under Configuring iSCSI Ports on page 5-4. 2. Configure the iSCSI access control list. Follow procedures under Configuring iSCSI Devices on page 5-13. 3. Zone the iSCSI devices appropriately using SANvergence Manager, so the initiators can talk to the targets. Refer to Zoning iSCSI Devices on page 5-19. 4.
Configuring iSCSI Ports 5 Figure 5-3 FC/Ethernet Port Configuration Dialog Box 2. Select a port. The screen is refreshed to show the operational state. 3. Type a label for this port in the Port Name field. 4. Set the port speed under the Port Speed list, if needed. Select the Enable Port checkbox. 5. Select or clear the Autonegotiations check box as required.
Configuring iSCSI Ports 5 6. Select the Flash LED option to blink the port LED. You can use this option to locate the physical port in a rack of SAN Routers. 7. Select the type of the port as iSCSI. Setting the Advanced TCP Parameters The SAN Router provides options to optimize the TCP port behavior for storage traffic in a dedicated enterprise network through a set of advanced parameters. Use the following procedure to configure the advanced TCP parameters. 1. Click the Advanced button.
Configuring iSCSI Ports 5 • Select Auto-reset port on severe errors especially when the port is a part of a mission-critical configuration. Manual Reset: You may not want the auto-reset option to be on when you are troubleshooting unrecoverable errors. In this case, you can do a manual reset by clicking Reset Port in the FC/Ethernet Port Configuration dialog box. 2. Set the MTU size.
Configuring iSCSI Ports 5 1. Select Smaller CWND Reduction in Fast Recovery to improve the performance of the SAN Router when packet losses occur due to reordering or noise rather than congestion. When enabled, the SAN Router responds more slowly to congestion events because the send congestion window (CWND) is reduced to 7/8 of its previous value as compared to 1/2 in standard TCP. NOTE: Do not select this option when other traffic sources sharing the same TCP link are bursty or intermittent. 2.
Configuring iSCSI Ports 5 NOTE: Enabling reorder resistance could slightly delay recovery from dropped packets in short data messages. Specify the number of ACKs that trigger Fast Retransmit or Fast Recovery using the Threshold field. Valid values are between 8 to 128, with a default of 8. Larger values reduce retransmissions by causing the SAN Router to wait longer for retransmitted packets to arrive. This may delay the detection of dropped packets.
Configuring iSCSI Ports 5 1. Select the iSCSI tab from the Advanced TCP Configuration dialog box (refer to Figure 5-5) to specify the iSCSI parameters: Figure 5-5 Advanced TCP Configuration iSCSI Parameters • Selective ACKnowledgement - (SACK) allows acknowledgement of non-contiguous sequence numbers to reduce the amount of retransmitted data when packets are lost. Enable this for better performance in congested networks (assuming the remote device also supports SACK).
Configuring iSCSI Ports 5 NOTE: Digest and large PDU cannot both be enabled at the same time. • Initial R2T - (request to transfer). This skips the requirement for an initial R2T in unidirectional and the output part of bidirectional commands. • Store and Forward - Enables the SAN Router to wait until all the data is received from a drive before delivering it to the initiator.
Configuring iSCSI Ports 5 • Login Retry timeout (in seconds) - This determines when the initiator can attempt to log into the SAN Router after a device is unzoned or disconnected. — Always Retry - iSCSI initiators are not notified that the device is no longer available. This allows the initiator to retry indefinitely. — Configure - Specify a value from 1 - 600 (secs). After this timeout expires, the SAN Router notifies the initiator that the device is no longer available.
Configuring iSCSI Devices 5 Configuring iSCSI Devices There are two ways to configure a SAN Router with a list of iSCSI devices (access control list) allowed to connect - Automatic Addition and Manual Configuration. To configure devices, select Configuration>iSCSI>Devices. The iSCSI Devices dialog box appears (Figure 5-7 on page 5-15).
Configuring iSCSI Devices 5 NOTE: This dialog box appears only if the software package supports iSCSI. When an iSCSI initiator attempts a login, an entry automatically appears in this dialog box when you refresh the screen using the F5 key. If the login from the Initiator includes an iSCSI Alias, it will overwrite any manually configured iSCSI alias. After the initiator entry appears in the iSCSI Devices list, save the configuration from the File menu of Element Manager.
Configuring iSCSI Devices 5 4. On the iSCSI Initiator, start the iSCSI login process. Some initiators may provide a button to initiate a login; others may require a reboot of the initiator. Messages should appear in the Element Manager Message Log, indicating that the initiator has registered with the name server on the SAN Router. The string appearing after InitiatorName: and between the brackets ('[', ']') is the InitiatorName that the iSCSI initiator is attempting to login with. 5.
Configuring iSCSI Devices 5 8. Type in the iSCSI identifier, IP address of the iSCSI device, target port, SAN Router port, role and iSCSI alias (optional), and other information in the respective fields. iSCSI Identifier is the iSCSI Initiator Name that you copied in step 5. If it was user-configurable, make sure it matches the name configured on the server. If it was copied from the Message Log in the Element Manager to the clipboard, press ^v with the cursor in the iSCSI Identifier field.
Configuring iSCSI Devices 5 iSCSI Devices Dialog Box Options and Data The following describes the fields in the iSCSI Devices dialog box where you can input information. • Enable - Select this to register the iSCSI device with the name service. • iSCSI Identifier - The unique textual name assigned to the iSCSI device by the device manufacturer. If the device is an FC device masquerading as an iSCSI device, it may have an identifier similar to eui.
Configuring iSCSI Devices 5 You cannot edit the remaining columns of the iSCSI device table. They show the SAN Router storage information associated with each iSCSI device. The iSCSI devices are registered in the mSNS as if they were FC devices. Each iSCSI device is registered as a different FC node. The iSCSI identifier becomes the FC Node Symbolic Name. The iSCSI alias becomes the FC Port Symbolic Name.
Zoning iSCSI Devices 5 Zoning iSCSI Devices Zoning is the process of controlling which targets are accessible to the initiator. Targets could have one or multiple LUNs. SAN Routers support LUN mapping/masking capabilities within the SAN Router for iSCSI initiators. If you want to leverage the LUN Mapping/Masking feature, use the following procedure. Zoning without LUN Mapping/Masking 1. Start SANvergence Manager 2. Select the proper mSAN from the list of mSANs in the mSAN pane. 3.
Zoning iSCSI Devices 5 6. Select the newly-created zone and the iSCSI initiator (WebServer) and click Add. With the newly-created zone selected, select each storage device you want the iSCSI initiator to access, and click Add. 7. Click Commit to save the changes to flash. NOTE: The iSCSI device you added in Element Manager automatically appears in the Devices tree of the mSAN Configuration screen under the appropriate SAN Router port that it was configured for.
Zoning iSCSI Devices 5 Setting Up a LUN Map and Mask 1. In the mSAN Configuration window, click New Zone to display the New Zone dialog box. 2. In the New Zone dialog box, type a zone name. 3. Select the newly-created zone and the FC Target with multiple LUNs that you want the iSCSI Initiator to access, and click Add. The zone configuration at this point is shown in the Figure 5-9. Figure 5-9 mSAN Configuration Window 4.
Zoning iSCSI Devices 5 6. Add the iSCSI initiator to the new zone. The new changes are visible in the mSAN Configuration window, as shown in Figure 5-11 on page 5-23. Figure 5-10 LUN Mapping/Masking Dialog Box CAUTION Adding a storage device with multiple LUNs to a zone that has initiators exposes all LUNs to the initiator. To selectively expose the LUNs to the initiators, carry out LUN Masking and Mapping first before you add a storage device to a zone with initiators in it.
Zoning iSCSI Devices 5 Figure 5-11 LUN Mapping/Masking Dialog Box 7. Click Commit to save the changes to flash. Now the iSCSI initiator will be able to login to the FC target and recognize the selected LUNs. Figure 5-12 on page 5-24 shows the three LUNs visible through the Windows 2000 disk management function.
Zoning iSCSI Devices 5 Figure 5-12 Computer Management Window CAUTION Changing the number of LUNs for a zoned target deletes the LUN map and forces the SAN Router to expose all LUNs to any initiators in the zone. To avoid this, remove the initiators from the zone before you change the number of LUNs on the target, and add the initiators back to the zone with appropriate permissions.
Configuring iSCSI Authentication 5 Configuring iSCSI Authentication SAN Routers support CHAP-based authentication of iSCSI initiators in conjunction with an external RADIUS server. Challenge Handshake Authentication Protocol (CHAP) provides a type of authentication between an agent (typically a network server) and the client program. Both share a predefined secret, which they verify during an authentication login sequence. The RADIUS protocol is used for access authentication and accounting.
Configuring iSCSI Authentication 5 Figure 5-13 Sample Authentication Configuration A typical interaction would be as follows: 1. The iSCSI initiator creates a “portal” session with the SAN Router. 2. The iSCSI initiator is configured to use CHAP authentication. The password and username have been configured in the iSCSI initiator. 3. The iSCSI initiator does not communicate with the RADIUS server directly. The SAN Router acts as a mediator between the iSCSI initiator and RADIUS server. 4.
Configuring iSCSI Authentication 5 Using Static Routes If your RADIUS server is attached via the SAN Router's management port, then you need to add a static route to the RADIUS server to reach the TCP port's internal address. Refer to Figure 5-14 on page 5-27. Figure 5-14 RADIUS Server on Management IP Subnet Static Routes NOTE: The only way the RADIUS server can access the internal IP network is through a static route within the RADIUS Server.
Configuring iSCSI Authentication 5 If you are having problems authenticating iSCSI login requests, make sure that the RADIUS server has logical connectivity to the iSCSI port address. You can confirm this with a ping to the internal address from the RADIUS server (ping 10.10.10.11). If the ping fails, iSCSI initiator will never receive the authentication grant.
Configuring iSCSI Authentication 5 3. Enter the UDP port on the RADIUS server to send the authentication requests. The RFC 2865 defaults this port to 1812, but can be different for other implementations. 4. Enter the timeout value in seconds. This is the timeout for each retry. If authentication does not occur and all retries have timed out, the secondary RADIUS server is contacted. 5. Enter the number of retries.
Configuring iSCSI Authentication 5 7. Choose Save Configuration to Flash from the File menu to permanently save the configuration to flash memory. Configuring the iSCSI Initiator for Authentication Refer to the documentation of your iSCSI initiator for instructions on setting up the initiator for CHAP authentication. Following is a procedure for using the Microsoft iSCSI initiator. 1.
Configuring iSCSI Authentication 5 Figure 5-18 Add Target Portal Advanced Settings Dialog Box 3. Enter a user name. Make sure that the Target secret matches the Password and Secret in the user and clients.conf file, if you are using the freeRADIUS RADIUS server. 4. Click OK to close the dialog box. 5. Click OK on the Add Target Portal dialog box. 6.
Configuring iSCSI Authentication 5 • Verify that the target displays on the iSCSI Initiator Properties dialog box as “connected.” If it doesn’t, you must check the storage array for configuration problems. • After you verify that an active session exists for the target, check the message log of the bottom of the Element Manager window on the SAN Router with the iSCSI port. A message should display that the iSCSI initiator is registering with the name server.

Configuring iSCSI Authentication 5 Figure 5-21 RADIUS Server Located on the Management Subnet Note that you need to add a static route to the RADIUS server that tells the IP stack on the RADIUS server that the path to the iSCSI port of the SAN Router is through its management port IP address. The RADIUS Server requires a static route logically pointing to SAN Router’s internal address: “route add 10.10.10.11 .255.255.255.255. 172.168.10.25.
Configuring iSCSI Authentication 5 Figure 5-22 RADIUS Server Configuration Dialog Box Configuration 4 - RADIUS Server Located One Hop from Management Subnet In this configuration, the RADIUS server is on a subnet that is one hop away from the SAN Router's 10/100 management subnet (refer to Figure 5-23 on page 5-37). The RADIUS client on the SAN Router will communicate with the RADIUS server via the 10/100 management port on the SAN Router.
Configuring iSCSI Authentication 5 Figure 5-23 RADIUS Server Located One Hop from Management Port Figure 5-24 on page 5-38 shows an example of the associated RADIUS Server Configuration dialog box in the Element Manager. Display this dialog box by selecting RADIUS Server Configuration under the Configuration menu, iSCSI submenu.
Configuring iSCSI Authentication 5 Figure 5-24 RADIUS Server Configuration Dialog Box If the RADIUS Server resides on a subnet that cannot be directly accessed from the SAN Router, establish a static route path between the server and the SAN Router. The Static Route Table (Table 5-1) shows all necessary static routes in this example. Table 5-1 Static Route Static Route Source Destination Address Mask Gateway Address RADIUS Server 10.10.10.11 255.255.255.255 172.168.15.
Configuring iSCSI Authentication 5 Figure 5-25 Add Static Route Dialog Box Configuration 5 - Unsupported Case, RADIUS Server Located on Alternate TCP Port In this configuration, the RADIUS server is on a subnet that is reachable only via a different iSCSI-capable port (refer to Figure 5-26 on page 5-40). This configuration is not supported.
Configuring iSCSI Authentication 5 Figure 5-26 RADIUS Server Located on Alternate TCP Port The primary and secondary RADIUS servers can be connected in any combination of the supported configurations. For example, the primary RADIUS server can be located on iSCSI port's subnet while the secondary RADIUS server can be located on iFCP subnet. Use the “ping” command to verify logical connectivity from the RADIUS server to the iSCSI port (internal or external).

RAM See random access memory. random access memory R_A_TOV g-48 RFI. Electromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of the normal operation, and which causes unwanted signals (interference or noise) to be induced in other circuits. RAM.
Glossary management protocol (SNMP) trap recipients are two examples of remote notification programs that can be implemented on director-class switches. remote user workstation repeater Workstation, such as a personal computer (PC), using EFC Manager application and Product Manager application software that can access the EFC Server over a local area network (LAN) connection. A device that generates and often amplifies signals to extend transmission distance.
Glossary SAN routers send data from one end node to another in a routed SAN is called SAN Routing or SAN Internetworking. router attached devices (RADs) End nodes that are either directly attached to an Fibre Channel port on a SAN Router or were imported from a different fabric via a SAN Router are referred to as router-attached devices. Devices that are directly attached to an Fibre Channel port on a router are called local router-attached devices (LRADs) within the context of that mSAN.
Glossary SANavigator SAN ID SANavigator management software provides easy, centralized management of a SAN and quick access to all device configuration applications. A number between 0 and 4,294,967,295 that uniquely identifies an mSAN. SANpilot interface The interface provides a graphical user interface (GUI) similar to the Product Manager application, and supports director or switch configuration, statistics monitoring, and basic operations.
Glossary SCSI segment segmented E_Port segmented expansion port A fabric segments when one or more switches cannot join the fabric because of various reasons. The switch or switches remain as separate fabrics. See segmented expansion port. Segmented E_Port. E_Port that has ceased to function as an E_Port within a multiswitch fabric due to an incompatibility between the fabrics that it joins. See also bridge port; fabric loop port; fabric port; generic port; hub port; node loop port; node port.
Glossary simple network management protocol SNMP. A transmission control protocol/Internet protocol (TCP/IP)-derived protocol governing network management and monitoring of network devices. simple network management protocol community SNMP community. Also known as SNMP community string. SNMP community is a cluster of managed products (in SNMP terminology, hosts) to which the server or managed product running the SNMP agent belongs. simple network management protocol community name SNMP community name.
Glossary small form factor pluggable transceivers SMTP SNMP See simple mail transfer protocol. See simple network management protocol. SNMP community See simple network management protocol community. SNMP community name See simple network management protocol community name. SNMP management station See simple network management protocol management station. SNMP v1 See simple network management protocol version 1. SNMP v2 See simple network management protocol version 2.
Glossary which the computer is connecting. The mask indicates which digits to look at in a longer network address and allows the router to avoid handling the entire address. Subnet masking allows routers to move the packets more quickly. Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network.
Glossary T TB TCP TCP/IP See transmission control protocol. See transmission control protocol/Internet protocol. technical support Single point of contact for a customer when assistance is needed in managing or troubleshooting a product. Technical support provides assistance twenty-four hours a day, seven days a week, including holidays. The technical support number is (800) 752-4572 or (720) 566-3910. Synonymous with customer support. Telecommunications Industry Association TIA.
Glossary token ring controller adapter card topology transceiver modules transfer rate transistor-transistor logic TKRG. The circuit card that provides a port to connect a director or switch to a 4/16 Mbps token ring local area network (LAN) (D). Logical and/or physical arrangement of stations on a network. Transceiver modules come in longwave, extra longwave, or shortwave laser versions, providing a single fiber connection. The speed with which data can be transmitted from one device to another.
Glossary TTL twisted pair See transistor-transistor logic. Relatively low-speed transmission medium consisting of two insulated wires arranged in a regular spiral pattern. The strands are twisted to improve protection against electromagnetic and radio frequency interference. The wires may be shielded or unshielded. U UDP UL ULP See Underwriters Laboratories. See upper level protocol.
Glossary has become the leading operating system for workstations. Historically, it has been less popular in the personal computer market, but the emergence of a new version called Linux is revitalizing UNIX across all platforms. upper level protocol ULP. Protocols that map to and run on top of the Fibre Channel FC-4 layer. ULPs include Internet protocol (IP) and small computer system interface (SCSI) (D). UPS See uninterruptable power supply. URL See uniform resource locator.
Glossary vital product data VM® VM/ESA® volt VPD. System-level data stored by field-replaceable units (FRUs) in the electrically erasable programmable read-only memory. This data includes serial numbers and identifies the manufacturer. See virtual machine. Virtual machine/Enterprise Systems Architecture. See virtual machine.
Glossary window The main window for the EFC Manager application or Product Manager applications. Each application has a unique window that is divided into separate panels for the title, navigation control, alerts, and the main or Product View. The user performs all management and monitoring functions for these Fibre Channel products through the application window. Windows A graphical user interface and windowing system introduced by Microsoft Corporation in 1985.
Glossary see each other. Those devices that occupy different zones cannot. A Fabric Zone is created in fabric using tools supported by a fabric switch or director. A Router Zone is created in SAN Router using tools used to manage SAN Router. See also zone set; zoning. Zone ID Every SAN router zone has a unique name and a unique ID. Zone IDs are used by the router to identify a zone whereas zone names are more for usability/readability for the user.
