Using the Planning Checklist
Using the Cluster Planning Work Sheet, you can record the names and locations of the
servers to be clustered. Appendix B, Blank Planning Forms
, contains a blank copy of
the Cluster Planning Work Sheet that you can photocopy. The form can accommodate
information for up to eight nodes. If your cluster will contain 8 through 16 nodes, make
two copies; if your cluster will contain more than 16 nodes, make three copies.
See the Cluster Planning Work Sheet (Example)
on page 2-5. It spans three pages
because it contains information for an 18-node cluster.
Make sure emergency power-off (EPO) cables, if
required, can be routed to the cluster switches.
