It will help you plan your management port network and security login information and storage system disk and switch information. For each storage system that you will configure, complete a copy of the enclosed worksheets.
Storage System Management Ports The storage system can have two management ports, one per storage processor (SP). Plan the network and security characteristics for each management port and record the data below. Your network administrator should provide this information. ❑ Provide a static IP address for each storage system MANAGEMENT port. Provide a username and password for your storage system.
Fibre Channel Switch Information If your configuration will use one or more Fibre Channel switches, complete a Switch information worksheet for each switch. If your site will not use switches, skip this section, and continue with "Storage System Disk Information" on page 6.
Sample Switch Information Worksheet A sample switch worksheet section follows. It describes one server with two HBAs and one storage system with two SPs.
Completing the Switch Information Worksheet On the worksheet, for each switch port, indicate the SP or HBA port to which the switch port will connect. SP-to-Switch Connections Specify the SP-to-switch connections. For preconfigured switches, ports 0 and 4 are the only two switch ports you can connect to storage system SP ports; if you will use both switch ports, specify connections for each. These identify the SP (A or B) and the SP port (labeled FE 0 or FE 1) that you will connect to each switch port.
Storage System Disk Information This section defines storage system disk information. Fill out the following worksheet as described in this section. Disk Information Disk Pool Disks to Form Pool (1-12) Capacity (Gbytes) Name Free Space (Gbytes) Capacity (Gbytes) Function Server To Be Assigned IN AR Y Number (1- 6 or Spare) Virtual Disk M Use this worksheet to list the disk pools and virtual disks that you will create.
If your system has two SPs, you should create at least two disk pools, since the software assigns one or more disk pools to each SP; that is, it assigns disk pool 1 and all its virtual disks to SP A, disk pool 2 and all its disks to SP B, disk pool 3 and its disks to SP A, and disk pool 4 and its disks to SP B. If you create only one pool, all virtual disks in the storage system will be assigned to SP A. Disks to form each pool For each pool, specify the numbers of the disks you will include.
Disk pool capacity (Gbytes) To calculate the size of a RAID 5 disk pool, multiply the number of disks less 1 (n-1) by the disk capacity. For a RAID 1/0 disk pool, multiply the number of disks by the disk capacity, then divide by 2. The following table shows the formatted capacity of SSR212PP-Series disks. 250 Gbyte Disks 500 Gbyte disks Disks 0-3 217 Gbytes per disk 458 Gbytes per disk Disks 4-11 230 Gbytes per disk 445 Gbytes per disk Y Name AR Name the virtual disks in each disk pool.

Planning Your iSCSI Storage System Configuration 3 AR Y This document is written for administrators who are planning and setting up iSCSI SSR212PP-Series storage systems. It will help them plan an internet SCSI (iSCSI) storage system configuration, and includes management port, iSCSI port, initiator iSCSI port, and disk information.
Introduction SSR212PP-Series iSCSI storage systems connect to servers through Internet SCSI (iSCSI) interfaces. Storage systems and servers can connect directly from one iSCSI port to another, or through an IP (Internet Protocol) network. iSCSI host bus adapters (HBAs) or network interface cards (NICs) in the servers act as the physical iSCSI interfaces. Y You must identify the network settings for each iSCSI I/O port in a storage system, including the IP address, subnet mask, and gateway address.
the initiators. To increase the level of security, you can also set up mutual CHAP authentication where initiators authenticate targets, thereby ensuring that the correct initiators are connecting to the correct targets. Planning worksheets CAUTION PR EL I M IN AR All of your security efforts will be nullified if you leave any completed worksheets in public places. Store them in a secure place.
iSCSI Configuration Rules Refer to this section as you plan your iSCSI environment with your network administrator. It provides minimal guidelines for configuring initiator servers and target storage systems in IP networks that use the iSCSI protocol. It is recommended to use discrete networks dedicated to iSCSI data traffic, but support other configurations. CAUTION AR Y The number and complexity of supported configurations is constantly growing.
You can connect up to four iSCSI HBAs or 4 NIC initiators (2 two-port NICs or 4 one-port NICs) in a server to one SSR212PP2i storage system. SSR212PPi systems support connection to 4 iSCSI HBAs 1 two-port NIC, or 2 one-port NICs. You cannot use both iSCSI HBAs and NICs in a single server. Separate servers with HBAs and servers with NICs can connect to the same storage system.
Administration Worksheet The accompanying Administration Worksheet contains the following blanks that you will need to fill in: Storage system management port Storage system iSCSI port Initiator iSCSI port Y Storage System Management Ports AR The storage system can have two management ports, one per storage processor (SP). Plan the network and security characteristics for each management port and record the data on the accompanying Administration Worksheet.
Class A: 10.0.0.0 - 10.255.255.255 Class B: 172.16.0.0 - 172.31.255.255 Class C: 192.168.0.0 - 192.168.255.255 Make sure that your assigned addresses do not conflict with other devices on the corporate network. Each NIC or HBA in your server requires a unique IP address. In a server with multiple NICs/HBAs attached directly to the storage system, or on a dedicated iSCSI network, the initiator ports must be on separate subnets.

SSR212PP2i Connected to a Dedicated iSCSI Network (MultipleInitiator Servers) Figure 13 shows an SSR212PP2i with up to ten servers. Each server has two iSCSI initiators, and is connected with Ethernet switches (dedicated for iSCSI traffic) to the storage system s four iSCSI data ports. This represents a secure and highly available SSR212PP2i configuration.
Using two storage processors improves overall storage system performance. Connection to each SP port from both servers provides redundant data paths in case one path fails. Disadvantages This configuration incurs the cost of a second switch. SSR212PPi Connected to a Dedicated iSCSI/Management Network (Single-Initiator Server) AR This configuration requires a NIC connection; iSCSI HBAs qualified on SSR212PP-Series systems do not support management input/output.
Management port IP addresses should match the corporate network scheme. Advantages Low-cost storage for up to ten servers. Improved security: System management requires a connection to the private network. Adding NICs to the configuration increases throughput. Connection to multiple servers maximizes use of the storage system s capabilities. Y A dedicated iSCSI LAN avoids network contention with your corporate LAN and reduces security risks.

Storage System Disk Information This section defines storage system disk information. Fill out the following worksheet as described in this section. Disk Information Disk Pool Disks to Form Pool (1-12) Capacity (Gbytes) Name Free Space (Gbytes) Capacity (Gbytes) Function Server To Be Assigned IN AR Y Number (1- 6 or Spare) Virtual Disk EL I M Use this worksheet to list the disk pools and virtual disks that you will create.
Number (1-6 or spare) You must create at least one disk pool for virtual disks. You can create up to four RAID 5 disk pools or six RAID 1/0 disk pools, numbered 1-6, in a storage system. If your system has two SPs, you should create at least two disk pools, since the software assigns one or more disk pools to each SP; that is, it assigns disk pool 1 and all its virtual disks to SP A, disk pool 2 and all its disks to SP B, disk pool 3 and its disks to SP A, and disk pool 4 and its disks to SP B.
Disk pool capacity (Gbytes) To calculate the size of a RAID 5 disk pool, multiply the number of disks less 1 (n-1) by the disk capacity. For a RAID 1/0 disk pool, multiply the number of disks by the disk capacity, then divide by 2. The following table shows the formatted capacity of SSR212PP-Series disks. 500 Gbyte disks Disks 0-3 217 Gbytes per disk 458 Gbytes per disk Disks 4-11 230 Gbytes per disk 445 Gbytes per disk Y 250 Gbyte Disks Name AR Name the virtual disks in each disk pool.
What is Microsoft iSNS? Microsoft Internet Storage Naming Service (iSNS) is an option that applies to configurations with multiple hosts. The iSNS service provides automated discovery, management and configuration of iSCSI devices. It eliminates the need to manually configure each individual storage device with its own list of initiators and targets. Once configured, the iSNS server assumes responsibility for the discovery and management of iSCSI devices.
Management station iSNS queries Clients (initiators) Management network Primary iSNS server Target registration Backup iSNS server Storage networks FIGURE 19. AR Target registration Y SSR212PPi EMC3165 Sample iSNS Storage Configuration PR EL I M IN The storage system actively communicates with only one iSNS server at a time (the primary server). You can add additional servers to act as backup (secondary) servers. 44 Intel Storage System SSR212PP User Guide Revision 1.
iSNS Server Worksheet Enter the public IP address and name of your network s primary iSNS server and secondary (backup) iSNS server if you have one. Note that the public IP address is not related to the server s iSCSI port addresses. iSNS Server Worksheet Server type Y TABLE 1.
What is CHAP? Challenge Handshake Authentication Protocol (CHAP) is an optional iSCSI authentication method where the target authenticates iSCSI initiators. CHAP consists of initiator CHAP and mutual CHAP, depending on which way the authentication occurs. For initiator CHAP, the target authenticates the initiator. Mutual CHAP can be configured in addition to initiator CHAP. For mutual CHAP, the initiator authenticates the target.
iSCSI CHAP Authentication Worksheets If the storage system is on a private LAN, you can elect not to configure CHAP authentication. If the storage system is on a public LAN, we strongly recommend that you set CHAP security. If you do not set CHAP security for the storage system, any host connected to the LAN can read from and write to the storage system.

CAUTION AR If you do not configure CHAP security for the storage system, any host connected to the same IP network as the storage-system iSCSI ports can read from and write to the storage system.
To set up mutual CHAP you must first configure advanced initiator CHAP. On each server that will use the storage system, configure initiator CHAP by entering the user data for each initiator that will connect to the target. The initiator sends this data to the target and the target uses this data to authenticate the initiator. On each server, ensure that the target is logged in to the initiators.ensure that the session is active, and that HBAs are logged in to the target.
v. Select the IP address of the Inactive target and click Remove. All targets for the storage system are removed. vi. Click Cancel to close the wizard. STEP 2. On a Windows server with iSNS, log off and remove targets: a. On the server that includes your iSCSI initiators, open the Microsoft iSCSI Software Initiator. b. Log off any connected targets you are setting up for CHAP: i. On the Targets tab, click Details and log off all targets. Y ii.
STEP 10. Enable basic CHAP on the storage system a. Open Navisphere Express on the storage system you are configuring. See Procedure 29, "Running Navisphere Express," on page 163. b. In the Navisphere Express navigation pane, under Manage, click iSCSI to open the Manage iSCSI screen. c. Under Security, click Basic. d. In the iSCSI Security - Basic screen, click Enable.
You will also enter this secret for the server initiators. You can specify the secret in ASCII or hexadecimal characters. ASCII secrets must consist of at least 12 and no more than 16 characters. Hexadecimal secrets must consist of at least 12 and no more than 16 pairs of data (24 to 32 characters). If you specify the CHAP secret using hexadecimal characters, you must select CHAP Secret Specified In Hex.
STEP 10. Click View mutual CHAP credentials and confirm that the new CHAP entry exists. STEP 11. Enable advanced CHAP on the storage system: a. In the Navisphere Express navigation pane, under Manage, click iSCSI to open the Manage iSCSI screen. b. Under Security, click Advanced. c. In the iSCSI Security - Advanced screen, click Enable.
Discover iSCSI targets using this iSNS Server discovers the specified IP address of the iSNS server. Click Next. If you entered the IP address of the iSCSI target and you have CHAP authentication enabled on that target, the CHAP login windows displays. Enter the CHAP security information (username and secret) and if you have mutual CHAP configured on the storage system and the server, check Mutual CHAP if you want mutual CHAP enabled on the initiator. Click Next. STEP 7.
Configuring Basic Chap on a Linux Server with NICs CAUTION CHAP security must be enabled on the storage systembefore using the Configure iSCSI connections on the Server Utility. AR Y After entering CHAP data on the target, you must enter the same data on each NIC initiator. On each initiator, you enter the initiator CHAP user account data (username and secret) that the initiator sends to the target for authentication.
