20 Cisco Systems Intelligent Gigabit Ethernet Switch Module
Figure 4-1 Cisco Systems IGESM architecture overview
We also discuss details about how the Cisco Systems IGESM in the BladeCenter chassis are
connected to the blade servers. Figure 4-2 shows the architecture for Ethernet connectivity.
The two Cisco Systems IGESMs can be housed within the BladeCenter chassis. Each Cisco
Systems IGESM provides four uplink ports, which can be grouped to support 802.3ad Link
Aggregation. The blade server has two NICs with NIC 1 connecting to Cisco Systems IGESM
1 and NIC 2 connecting to Cisco Systems IGESM 2. The links connecting the blade servers to
the Cisco Systems IGESMs are on the backplane of the BladeCenter chassis. The Cisco
Systems IGESM has two links to the Management Modules. Each link connects to a different
Management Module.
