Appendix A Alternate Sun Fire V20z and V40z Reference Configuration

Sun Fire V20z and V40z servers have two management ports, SP0 and SP1, as shown by the following logical port diagram.

The Sun Fire V20z and V40z servers can be connected to a switch in either of two ways:

• Direct connections:

  The SP0 port of each server connects directly to the switch for the management network. Therefore, the switch must have a 1–Mbit port for each server.

• Daisy-chaining:

  • The SP0 port of the first server must be connected to the switch.

  • The SP1 port of the first server must be connected to the SP0 port of the second server.

  • The SP1 port of the second server must be connected to the SP0 port of the third server and so on.

  Tip –

  To ensure performance, daisy-chain up to five Sun Fire V20z and V40z architecture machines. If you have more than five Sun Fire V20z or V40z management port machines, daisy-chain the machines in clusters of five.

  ---

  Therefore, the switch needs only one 1–Mbit port for each group of five Sun Fire V20z and V40z servers.

The following figure illustrates a Sun Fire V20z and V40z daisy-chained configuration.
