Chapter 2. Cluster Planning
The area of cluster planning is a large one. Not only does it include planning for the types of hardware (CPUs, networks, disks) to be used in the cluster, but it also includes other aspects. These include resource planning, that is, planning the desired behavior of the cluster in failure situations. Resource planning must take into account application loads and characteristics, as well as priorities. This chapter will cover all of these areas, as well as planning for event customizations and user id planning issues.
2.1 Cluster Nodes
One of HACMP’s key design strengths is its ability to provide support across the entire range of RISC System/6000 products. Because of this
In this chapter, we shall outline the various hardware options supported by HACMP for AIX and HACMP/ES. We realize that the rapid pace of change in products will almost certainly render any snapshot of the options out of date by the time it is published. This is true of almost all technical writing, though to yield to the spoils of obsolescence would probably mean nothing would ever make it to the printing press.
The following sections will deal with the various:
•CPU Options
•Cluster Node Considerations
available to you when you are planning your HACMP cluster.
2.1.1 CPU Options
HACMP is designed to execute with RISC System/6000 uniprocessors, Symmetric
Almost any model of the RISC System/6000 POWERserver family can be included in an HACMP environment and new models continue to be added to the list. The following table gives you an overview of the currently supported
