Multiple BladeCenter chassis
You can deploy a series of BladeCenter units as a network infrastructure solution.
In this configuration, each BladeCenter unit contains two Ethernet switch modules
and one management module. Both the external ports on the switch modules and
the corresponding ports on the attaching external LAN switches are configured for
multi-port link aggregation groups (or trunks). All switch module ports in switch bay
1 in the BladeCenter units are connected to the same external LAN switch and all
switch module ports in switch bay 2 in the BladeCenter units are connected to the
second external LAN switch.
Observe the following guidelines when creating this topology:
1. The external ports on the BladeCenter switch modules are designed for
point-to-point, full-duplex operation to a compatible LAN switch or router.
Configure a corresponding multi-port link aggregation group, or trunk, in both
the switch module and the attaching LAN switch prior to installing the cables.
The connection options are as follows, in order of preference:
v
Multi-port Link Aggregation Group or Trunk, 1 Gbps (1000 Mbps) per port
v Single-uplink port, 1 Gbps
v
Multi-port Link Aggregation Group or Trunk, 100 Mbps per port
2. Connect the management module 10/100 Mbps Ethernet port to a separate
network if possible, for security purposes. If a separate network is not available,
connect the Ethernet ports of the management modules and switch modules to
the same network.
3. Avoid network configurations that could lead to data loops, if possible. Loops
are created when you connect multiple ports from the same switch module to
