IBM 44W4479 interface cards/adapter

The IBM 2/4 Port Ethernet Expansion Card (CFFh) for IBM BladeCenter is the perfect example of IBM's goal to meet user requirements in the BladeCenter environment. In addition to the two onboard Ethernet ports, this card allows the client to add up to four (in IBM BladeCenter H chassis) or two (in BladeCenter S) extra 1 Gb ports thereby allowing them to leverage the benefits of 6/4 ports per blade. This card provides support for up to four Low Speed Switch Module (LSSM) switches within the Multi-Switch Interconnect Module (MSIM) in BC-H chassis (1 LSSM switch in BC-S). Some of the high-level features included in this offering are:

- Based on the Broadcom 5709 module
- PCI Express x4 Host host interface for high-speed connection
- Connectivity to either standard or high-speed I/O modules bays (depends on chassis)
- Multiple connections from the blade server to the external network
- Ability to function as a 2-port Ethernet NIC in BC S chassis or a 4-port Ethernet NIC in a BC H chassis
