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 1-5Daisy 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.
