8 IBM Certification Study Guide AIX HACMP
RISC System/6000 models as nodes in an HACMP 4.1 for AIX, HACMP 4.2
for AIX, or HACMP 4.3 for AIX cluster.
Table 3. Hardware Requirements for the Different HACMP Versions
1 AIX 4.3.2 required
For a detailed description of system models supported by HACMP/6000 and
HACMP/ES, you should refer to the current Announcement Letters for
HACMP/6000 and HACMP/ES.
HACMP/ES 4.3 further enhances cluster design flexibility even further by
including support for the RISC System/6000 family of machines and the
Compact Server C20. Since the introduction of HACMP 4.1 for AIX, you have
been able to mix uniprocessor and multiprocessor machines in a single
cluster. Even a mixture of “normal” RS/6000 machines and RS/6000 SP
nodes is possible.
2.1.2 Cluster Node Considerations
It is important to understand that selecting the system components for a
cluster requires careful consideration of factors and information that may not
be considered in the selection of equipment for a single-system environment.
In this section, we will offer some guidelines to assist you in choosing and
sizing appropriate machine models to build your clusters.
