Daisy-Chaining the Servers
You can interconnect multiple servers in a daisy chain configuration by using the SP
connectors to form a management LAN as shown in
FIGURE 1-5 . This figure also
shows how the servers are connected to external LANs using the platform gigabit
connectors.
FIGURE 1-5 Daisy Chain Architecture
To interconnect the servers, you must use an RJ-45 cross-over cable. Cables can be
connected to either the top or bottom SP port. To configure servers in a daisy chain,
connect the first and last server in the chain to different switches.
Managed spanning-tree capable switches are required to redundantly connect both
the top and bottom of the chain. If the switch is not capable of spanning-tree
discovery, then only connect either to the top or the bottom of the chain, but not
both.
