20 Implementing Cisco InfiniBand on IBM BladeCenter

The Ethernet Bridge Module offers six 10/100/1000 Mbps external Ethernet RJ45 ports to

connect to an upstream Ethernet network, and two 4x internal InfiniBand ports to connect to

the 4x switch modules in slot 7 and 9. See Figure 2-4. It has support for many of the common

Ethernet based technologies, such as 802.3ad link aggregation, 802.1Q VLAN trunking and

jumbo frames. Management is through either a browser-based GUI interface or a CLI-based

interface, with management connectivity coming through Ethernet ports that connect from the

bridge module to the BladeCenter H Management Module slots.

This product can help simplify server deployments by allowing the BladeServer to only have a

single physical interconnect (InfiniBand) and still have access to other technologies, such as

Ethernet with this module or Fibre Channel through the QLogic InfiniBand to FC bridge

module.

The Ethernet bridge module has the following features and specifications:

򐂰 Support for two internal InfiniBand double-data rate (DDR) capable 4X (20 Gbps) links to

the high-speed switch modules (HSSMs)

򐂰 Support for various types of transport data traffic:

– Reliable

– Unreliable

– Connected

Note: If the bridge module is installed in bay 4 or 6 there will not be an internal InfiniBand

connection because the 4X InfiniBand HCA does not have a third and fourth port routed to

bays 8 and 10. See 1.4, “High-speed I/O paths in BladeCenter H” on page 13.
