22 Implementing Cisco InfiniBand on IBM BladeCenter
through Ethernet ports that connect from the bridge module to the BladeCenter H
Management Module slots.
As with the Ethernet Bridge Module, 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 Fibre Channel through the QLogic InfiniBand to
FC bridge module.
