Hardware Requirements

You must meet the following hardware requirements to install Arcserve Backup as a CLUSTERPRO/ExpressCluster-aware application:

• Ensure that all cluster nodes have identical hardware configurations (for example, SCSI adapters, Fiber Adapters, RAID Adapters, network adapters, and disk drives).
• Use separate SCSI/Fiber adapters for disk and tape devices.

  Note: Ensure that the hardware for all nodes is similar, if not identical, to make configuration easier and eliminate any potential compatibility problems.
