4.3 Hardware Requirements

The following hardware requirements for installing Novell Cluster Services represent the minimum hardware configuration. Additional hardware might be necessary depending on how you intend to use Novell Cluster Services.

In addition, each server must meet the requirements for Novell Open Enterprise Server 2 Linux. For information, see Meeting All Server Software and Hardware Requirements in the OES 2 SP3: Installation Guide.

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 and be configured the same way on each node.
