Each blade server has two independent Ethernet controllers, each with its own
MAC address and a dedicated 1000-Mbps link to one of the I/O modules (Controller
1 to Switch A and Controller 2 to Switch B in this diagram). In this configuration (the
default), the blade servers share access to four external ports on each I/O module.
There is no internal data path between the two switches within the BladeCenter
chassis; an external network device is required for data packets to flow from one
internal switch to the other.
The management module has a separate internal 100-Mbps link to each switch.
These links are for internal management and control only. No data packets are
allowed to flow from application programs on the blade servers to the management
module over this path. A separate, nonswitched path (not shown) is used for
communication between the management module and a service processor on each
blade server.
A typical, preferred BladeCenter network topology is shown in the following
illustration. See the
IBM BladeCenter Planning and Installation Guide
for more
information and other topologies and guidelines.
