vRedundancy capabilities

The redundant components in the rear of your BladeCenter unit enable continued operation if one of the components fails.

Power modules and blowers: Normally, the redundant power modules and blowers share the load. If one of the power modules or blowers fails, the non-failing power module or blower handles the entire load. You can then replace the failed blower or power module without shutting down the BladeCenter unit.

Management modules: Only one management module will be active at a time. If the active management module fails, the secondary, or redundant, management module becomes the active management module, containing current BladeCenter configuration and status information. You can then replace the failed management module without shutting down the BladeCenter unit.

vRedundant network connection capabilities

Configuring a pair of Ethernet switch modules in I/O-module bays 1 and 2 identically provides support for Ethernet failover configured on blade servers. See “Configuring a switch module” on page 46 for more information. If the I/O expansion options in your blade servers can be configured for failover, configuring a pair of switch modules in I/O-module bays 3 and 4 identically provides support for the failover configured on the I/O expansion options.

Other network-interface I/O expansion options, such as the IBM HS20 Fibre Channel Expansion Card, can have similar capability for redundant network connections. See the documentation that comes with your I/O expansion and switch module options for more information about configuring for redundant network connections.

vSystem-management capabilities

Your BladeCenter unit comes with a service processor in the management module. This service processor, in conjunction with the system-management firmware that is provided with your BladeCenter unit and the service processor in each blade server, enables you to remotely manage the BladeCenter unit, its components, and the blade servers. The management module also multiplexes the keyboard, mouse, and video ports and the USB port across the multiple blade servers.

The service processor in each blade server provides blade server system monitoring, event recording, and alert capability.

See Chapter 4, “Configuring your BladeCenter unit”, on page 37 for more information.

vNetwork environment support

Your BladeCenter unit supports up to two Ethernet-compatible I/O modules (switch modules or pass-thru modules), for blade server integrated Ethernet controller communication with the network. Each I/O module provides one internal connection to each blade server, up to 14 internal connections per I/O module.

The BladeCenter unit also supports two additional I/O modules, for a total of four I/O modules. The two additional I/O modules support the network interface on the optional I/O expansion card installed on one or more blade servers in the BladeCenter unit.

Note: The two additional I/O modules must be compatible with the network interface on the optional I/O expansion cards in the blade servers.
