Figure 23. Multiple BladeCenter T units as a network infrastructure
In this configuration, each BladeCenter T unit contains two Ethernet switch modules
and one management module. The external ports on the switch modules are
configured for multiport link aggregation groups or trunks, as are the corresponding
ports on the attached external LAN switches. Additionally, every port in the switch
module in I/O-module bay 1 (switch A in this illustration) in the BladeCenter T units
is connected to the same external LAN switch and every port in the switch module
in I/O-module bay 2 (switch B in this illustration) in the BladeCenter T units is
connected to another external LAN switch.
Observe the following guidelines when creating this topology:
1. The external ports on the BladeCenter T I/O modules are designed for
point-to-point, full-duplex operation to a compatible LAN switch or router.
Configure a corresponding multiport link aggregation group, or trunk, in both the
switch module and the attached LAN switch before installing the cables. The
connection options are as follows, in order of preference:
v Multiport link aggregation group or trunk, 1 Gbps (1000 Mbps) per port
v Single-uplink port, 1 Gbps
v Multiport link aggregation group or trunk, 100 Mbps per port
