This high-availability cluster configuration includes the following hardware components:

  • Independently powered system cabinet with two identically configured member systems, local storage shelves, and redundant Memory Channel hubs
  • Independently powered storage cabinet, which includes dual-redundant RAID controllers, an UltraSCSI hub, and shared storage shelves
  • Shared tape devices
  • Redundant uninterruptible power supplies (UPSs)

The following tables describe these components in more detail. The images highlight particular details of the cluster configuration. (Images are displayed in a separate window.)
