Planning and Documenting an HA Cluster
Hardware Planning
Chapter 496
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.
Then record the information on the Hardware Worksheet (page 364).
Indicate which device adapters occupy which slots. Update the details as
you create the cluster configuration (described in“Building an HA
Cluster Configuration” on page 141).
Use one form for each node (server).
SPU Information
SPU information includes the basic characteristics of the server systems
you are using in the cluster. Different servers can be mixed in the same
cluster however, they must all be running the same version of the
operating system (i.e. IA64, x86-64, etc.) This includes both uniprocessor
and multiprocessor computers.
On one worksheet per node (see “Hardware Configuration Worksheet” on
page 101), include the following items:
Server Series Number
Enter the series number, for example, DL380 G5.
Host Name
Enter the name to be used on the system as the host
name.
Memory Capacity
Enter the memory in MB.
Number of I/O slots
Indicate the number of slots.
