Software Requirements - Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual

In addition, each server must meet the requirements for Novell Open Enterprise Server 2 Linux. For
information, see
Installation
NOTE: Although identical hardware for each cluster server is not required, having servers with the
same or similar processors and memory can reduce differences in performance between cluster
nodes and make it easier to manage your cluster. There are fewer variables to consider when
designing your cluster and failover rules if each cluster node has the same processor and amount of
memory.
If you have a Fibre Channel SAN, the host bus adapters (HBAs) for each cluster node should be
identical.
