Planning and Documenting an HA Cluster
Hardware Planning
Chapter 4 89
Hardware Planning
Hardware planning requires examining the physical hardware itself.
One useful procedure is to sketch the hardware configuration in a
diagram that shows adapter cards and buses, cabling, disks and
peripherals. A sample diagram for a two-node cluster is shown in
Figure 4-1.
Figure 4-1 Sample Cluster Configuration
Create a similar sketch for your own cluster, and record the information
on the Hardware Worksheet (page 326). Indicate which device adapters
occupy which slots, and determine the bus address for each adapter.
Update the details as you do the cluster configuration (described in
Chapter 5).
Use one form for each SPU.
