Introduction Virtual Connect documentation The following Virtual Connect documentation is available on the HP website (http://www.hp.com/go/bladesystem/documentation): • HP Virtual Connect for c-Class BladeSystem User Guide This guide provides details for the Virtual Connect GUI, including descriptions of screen contents and steps to set up domains, profiles, networks, and storage.
Overview Virtual Connect overview Virtual Connect is a set of interconnect modules and embedded software for HP BladeSystem c-Class enclosures that simplifies the setup and administration of server connections.
By stacking (cabling) the Ethernet modules within the domain and connecting the FC modules to the same set of FC SANs, every server blade in the domain can be configured to access any external network connection. With this configuration, the administrator can use Virtual Connect Manager to deploy and migrate a server blade profile to any server in the Virtual Connect domain without changing external LAN or SAN configurations.
HP Virtual Connect Manager Configuring browser support Access to the application must be through HTTPS (HTTP exchanged over an SSL-encrypted session). For optimal viewing, HP recommends setting the screen resolution to 1280 x 1024. Requirements The HP Virtual Connect Manager Web interface requires an XSLT-enabled browser with support for JavaScript 1.3 or equivalent. The following browsers are supported: • Microsoft® Internet Explorer 7.x or higher • Mozilla Firefox 3.
Always apply relevant licenses that are dependent on MAC addresses after the server profiles are assigned so that the licenses are not lost due to a change in MAC address. IMPORTANT: If you plan to use RDP for RedHat Linux installation and also plan to use Useror HP-defined MAC addresses, you must import the enclosure before running RDP. RDP "rip and replace" is not supported in a Virtual Connect environment.
Command line overview The HP Virtual Connect Manager Command Line Interface can be used as an alternative method for managing the Virtual Connect Manager. Using the CLI can be useful in the following scenarios: • HP Management Applications (for example, Systems Insight Manager or Insight Control tools) can query the Virtual Connect Manager for information these tools need to present a complete management view of HP BladeSystem enclosures and devices.

For additional information, see "MAC address settings (on page 63)." MAC Address Settings IMPORTANT: Configuring Virtual Connect to assign server blade MAC addresses requires careful planning to ensure that the configured range of MAC addresses is used once within the environment. Duplicate MAC addresses on an Ethernet network can result in a server network outage. Each server blade Ethernet NIC ships with a factory default MAC address.
Multifunction Gigabit server adapter. Only the primary MAC address is used by standard (not multifunction) Ethernet devices. • If a server blade is moved from a Virtual Connect managed enclosure to a non-Virtual Connect enclosure, the local MAC addresses on that server blade are automatically returned to the original factory defaults.
Whenever port monitoring is enabled, a warning icon appears in the banner at the top of the page. If port monitoring is configured and enabled within the Virtual Connect domain, Ethernet data from the monitored ports is replicated on the network analyzer port, which poses a security risk and could result in network loops if not connected properly.

Server VLAN Tagging Support This option provides explicit VLAN tagging support for server links, enabling each server link to be shared among multiple networks. Users can map server VLAN-tagged Ethernet packets to specific networks, which is essential in deploying server virtualization applications such as a virtual operating system solution.
The following figure shows tunneled VLAN tags. On the dedicated, green network, both uplink and server VLAN tags are tunneled through Virtual Connect unchanged. On the shared, red and blue networks, uplink VLAN tags are mapped to networks. Untagged frames are mapped to the native VLAN, if present, otherwise they are dropped. Server frames are untagged only, and tagged frames are dropped. Each server port is connected to a single network.
possibility of configurations where server VLANs might not match external VLANs used on uplinks. To avoid this scenario, you can select the 'Force server connections to use the same VLAN mappings as shared uplink sets' option. Server port connections to networks are defined on the Define Server Profile screen (on page 100). Restrictions and limitations • • Maximum number of networks per shared uplink set: o For Virtual Connect v2.30 and later – 128 networks o For Virtual Connect v1.
o No server profile connections are assigned to multiple networks not linked to a Shared Uplink Set. This action forces all server connections mapped to multiple networks to be linked to a shared uplink set. Server administrators cannot override this selection when creating or editing a profile. Multiple Networks Link Speed Settings When using mapped VLAN tags (multiple networks over a single link), these settings are used for the overall link speed control.
Stacking Links screen To access this screen, click the Stacking Links link under Fibre Channel Settings in the left VC Manager navigation window. Be sure to connect any Ethernet module stacking cables before running the network setup wizard. IMPORTANT: For a Virtual Connect environment to operate properly, all for Integrity BL8x0c i2 Server Bladess within the Virtual Connect domain must be interconnected with stacking links.
Port X0 indicates the 10Gb port connected through the midplane of horizontally-adjacent VC-Enet modules. Ports X7 and X8 connect to the internal link between horizontally-adjacent Flex-10 enabled VC-Enet modules. NOTE: Virtual Connect does not support stacking for FC modules, so each VC-FC module requires uplink connections to the external FC SAN environment.
For Virtual Connect v1.34 and Virtual Connect v2.10, a maximum of 64 associated networks is supported in each shared uplink set. All other versions support a maximum of 32 networks per shared uplink set. The following table describes the fields within the Define Shared Uplink Set screen.

Server management Server profile overview A Virtual Connect server profile is a logical grouping of attributes related to server connectivity that can be assigned to a server blade. The server profile can include MAC address, PXE, and network connection settings for each server NIC port and WWN, SAN fabric connection, and SAN boot parameter settings for each Fibre Channel HBA port. After being defined, the server profile can be assigned to any server blade within the Virtual Connect domain.
Virtual Connect domain that has existing profiles, an option to add FC connections appears in the existing profiles during editing. • Some server profile SAN boot settings (controller boot order) are applied by Virtual Connect only after the server blade has been booted at least once with the final mezzanine card configuration.
“Bays 1-4 (HP Integrity BL890c i2)”. This is true in the left navigation tree, in the Server Bays summary screen, in the list of bays that a profile can be assigned to in the Edit Server Profile screen, and so on. A profile is assigned to an entire multi-blade server, not to the individual blades in the server.
Although these four FlexNICs share a single 10Gb physical interface, Virtual Connect is able to keep traffic for the FlexNICs isolated, and each FlexNIC is assigned to a different Virtual Connect network. Each FlexNIC can be assigned a different bandwidth (from 100Mb to 10Gb), which is enforced by hardware mechanisms.
Flex-10 configuration Network administrator For each Virtual Connect network, the network administrator can set a "Preferred" and "Maximum" speed for FlexNICs that connect to that network. FlexNICs cannot connect to a network at a speed higher than the maximum speed set by the network administrator for that network. The "preferred" speed setting is the speed recommended by the network administrator for any FlexNIC that attaches to that network.
The Allocated Bandwidth column displays "not allocated" until the profile is assigned to a device bay that contains a server. At that time, bandwidth is allocated to each connection and the result is reported in this column. See "Bandwidth assignment (on page 98)." The Mapping column describes how each connection of a profile is assigned to physical devices in a server, and to which interconnect bay that device is connected.
8. Assign profile connection 8 to LOM port 2 because it is Flex-10 capable and can support up to four connections. For information about multi-blade server port assignments, see "Multi-blade servers (on page 93)." Bandwidth assignment In Flex-10 environments, four FlexNICs must share a single 10Gb link. Each FlexNIC is allocated a portion of that 10Gb link's bandwidth.
Requested Calculation Allocation + remainder FlexNIC a 1Gb (1/12)*10Gb = 800Mb 900Mb FlexNIC b 2Gb (2/12)*10Gb = 1600Mb 1700Mb FlexNIC c 4Gb (4/12)*10Gb = 3300Mb 3300Mb FlexNIC d 5Gb (5/12)*10Gb = 4100Mb 4100Mb 2. Every FlexNIC that is linked must be allocated at least 100Mb. For example, if four FlexNICs on a given port have requested bandwidth settings of 2Gb, 8Gb, Auto, and Auto, their allocated bandwidth is as shown in the table below.
Only the first FlexNIC on each physical port of a Flex-10 device can be used for PXE boot. Virtual Connect cannot enable PXE boot on the remaining FlexNICs of a physical port. Redundancy for PXE operations can be achieved using multiple PXE enabled NICs. However, the Virtual Connect Manager is limited to enabling only one NIC for PXE booting.
Column name Description Profile Profile Name Descriptive name for the server profile. The specified text is used as the base (prefix) for the name of the created Virtual Connect server profiles. The text can be up to 48 alpha-numeric characters, dashes, and underscores. Do not use spaces. Advanced Profile Settings (on page 103) Select to show if server factory defaults are being used for Ethernet MAC Addresses, Fibre Channel WWNs, and Serial Numbers (Logical).
Column name Description Model Model name of the server blade in the device bay Status Status of the server blade in the device bay UID Icon indicates if the server blade UID is on or off If VC-assigned MAC addresses, WWNs, or non-default Fibre Channel boot parameters are being used, always power off the affected server blades before assigning a profile. When assigning a VC-assigned serial number (logical), power off the server.
b. Click the down arrow under Port Speed to select Auto, 2Gb, 4Gb, 8Gb, or Disabled for that port. Auto is the default. 6. To modify the Fibre Channel boot parameters, select the Show Fibre Channel Boot Parameters checkbox. See "Fibre Channel boot parameters (on page 107)." 7. To assign the server profile to a device bay, click the down arrow next to Select Location to select an enclosure and bay number. This step can be deferred.
CAUTION: To avoid storage networking issues and potential loss of data associated with duplicate WWNs on a FC SAN fabric, plan carefully when allowing Virtual Connect to assign server blade WWNs so that the configured range of WWNs is used only once within the environment. Multiple network connections for a server port Server port connections to virtual networks are defined on the Define Server Profile screen (on page 100). Previous to Virtual Connect Manager v1.
With this 'forced' option selected, the server connection VLAN mappings are linked to the chosen shared uplink set. Any change to the uplink VLAN mappings is reflected automatically on the server connection using those shared uplink set VLAN mappings. Therefore, to minimize network outage time, any VLAN mapping changes to the uplinks requires immediate changes being made to the VLAN tagging on the servers.
the server side. Finally, to simplify configuration, a "Copy From…" button is available to copy existing network mappings from a shared uplink set or from other server ports. VLAN ID mapping guidelines • For each server port, all VLAN mappings must be unique. When the 'Force same VLAN mappings as Shared Uplink Sets' option is selected, this setting is handled automatically because all networks within a shared uplink set must have unique VLAN IDs.
Server network mapping is similar to the set of networks defined under a shared uplink set. The only difference is that when defining a shared uplink set, the networks are created in the Virtual Connect Domain along with options such as "Native VLAN", "Smart Link", and so on, while defining server network mappings does not result in creation of any networks in the VC Domain.
Define a Server Profile screen ("Define Server Profile screen" on page 100). To access the Fibre Channel boot parameters, select the Show Fibre Channel Boot Parameters checkbox. There are four SAN Boot options: • Use BIOS/EFI (default)—SAN boot settings are not configured by Virtual Connect Manager. BIOS settings are used. • Primary—Port is enabled for SAN boot, and is first in the boot order. • Secondary—Port is enabled for SAN boot, and is second in the boot order.
Server Profiles screen This screen lists all server profiles that have been defined within the domain, including assigned and unassigned profiles. From this screen, users can see the assigned device bays, NIC MAC addresses, FC HBA WWNs, network connections, and Fibre Channel Fabric and Boot Parameters for all server profiles as well as generate a printable report of this information.

Enable or disable PXE, or use the Use BIOS setting Click the drop-down arrow in the PXE column and select enabled, disabled, or Use BIOS.
Server profile troubleshooting In some cases, server profiles can be assigned to server blades when certain mismatches exist between the server profile definition and the server blade. The following list summarizes Virtual Connect behavior under these circumstances: • If the number of Network connections in the profile is more than the number of physical Ethernet ports, the profile is assigned, but a warning message appears.
• Making modifications to a profile that affect settings on the server blade; for example, PXE enable/disable, changing the number of connections, or changing Fibre Channel boot parameters • When assigning a VC-Assigned serial number (logical) The following operations do not require the server blade to be powered off: • Changing the network connected to an already defined Ethernet port • Changing the Fabric connected to a Fibre Channel port • Changing the speed of a Fibre Channel port • Assignin
• Changing the requested bandwidth Restart after OA credential recovery For VC v1.21 and higher, the VC Manager behavior has changed for powered-up servers when restarting after a recovery of OA credentials. In previous versions, the servers entered a "profile pending" state and required a power cycle to recover. For VC v1.21 and higher, a new state, "profile recovered," is applied to servers that are powered on when VC Manager restarts after an OA credential recovery.

Certificate Administration Certificates/Authentications (SSL Certificate) screen This page displays the detailed information of the Secure Socket Layer (SSL) Certificate currently in use by the Virtual Connect Manager. An SSL certificate is used to certify the identity of the Virtual Connect Manager and is required by the underlying HTTP server to establish a secure (encrypted) communications channel with the client Web browser.
The following table describes the tables within the Certificate/Authentications (SSL Certificate) screen. Row Description Issued to The subject, or "Common Name," to which this SSL Certificate is issued. By default, this is the dynamic DNS name of the HP 1/10Gb VC-Enet Module. If a Virtual Connect domain IP address is configured, a new certificate request is issued to the domain IP address.
Note that a new certificate request is generated each time this web page is visited, so the content may not be the same each time. Certificate Upload There are two methods for uploading certificates for use in the Virtual Connect Ethernet module: • Paste the certificate contents into the text field, and then click Upload. • Paste the URL of the certificate into the URL field, and then click Apply.
If the new certificate is successfully accepted and installed by the Virtual Connect Manager, you are automatically logged out. The HTTP server must be restarted for the new certificate to take effect. Certificates/Authentications (SSH Administration) This screen lists the current user (assuming administrator privileges) of each authorized SSH key and enables the user to add new keys. Only local users can have authorized SSH keys.
When a user has authorized one or more SSH keys, the user can delete all of them by clicking Clear SSH Keys. Removing the authorized SSH keys does not affect current SSH sessions. Web SSL Configuration This screen enables you to change the currently configured SSL encryption strength. This screen is only available to users with Domain Administration privileges.
When the web SSL encryption strength is changed, logged in users are notified that they must reconnect.

Server Bays Summary screen Device bay numbering is affected by whether the 'Allow the double density device bays' option was selected while using the Domain Setup Wizard. Bays might appear as 'Covered' or 'Unknown.' For more information, see "Double-dense server bay option (on page 146)." If a multi-blade server is installed, the bay numbering shows a span of bays, for example, Bays 1-4, in the Bay column. For more information, see "Multi-blade servers (on page 93).
Double-dense server bay option If the 'Allow the double density device bays' option was selected while using the Domain Setup Wizard, VC Manager displays the server bays as double-dense, regardless of the actual hardware installed. For example, if a full-height server blade is installed in physical Bay 1 of a double-dense enabled enclosure, Bay 1A and Bay 1B in VC Manager are displayed as 'Covered.
Use of the double-dense server bay option requires OA version 2.20 or higher. If the OA is downgraded to a lower version, subsequent recovery of the double-dense enabled enclosure results in bays A and B being marked 'Unknown.
