* Superdome 32-socket system requires an I/O expansion cabinet for greater than 4 nodes. Superdome 64-socket system requires an I/O expansion cabinet for
greater than 8 nodes.
NOTE: NOTE NOTE NOTE
"Recommended" refers to configurations that are fully qualified and offer the best bandwidth performance.
"Supported" refers to configurations that are fully qualified, but do not necessarily offer the best performance.

Redundant paths to storage devices used by the cluster are required and can be accomplished using either disk
mirroring or via LVM's pvlinks.
Redundant storage device paths should be configured in separate I/O chassis when possible.
Dual power connected to independent power circuits is recommended.
Cluster configurations can contain a mixture of Superdome and non Superdome nodes.
Care must be taken to configure an even or greater number of nodes outside of the Superdome cabinet
If half the nodes of the cluster are within a Superdome cabinet, a cluster lock is required
(4-node maximum cluster size)
If more than half the nodes of a cluster are outside the Superdome cabinet, no cluster lock is required (16-node
maximum Serviceguard cluster size).
Up to a 4-node cluster is supported within a single cabinet system (Superdome/16-socket or Superdome/PA-
8800 32-socket)
Up to an 8-node cluster is supported within a single cabinet system* (Superdome/32-socket or Superdome/PA-
8800 64-socket)
Up to a 16-node cluster is supported within a dual cabinet system* (Superdome/64-socket or Superdome/PA-
8800 128-socket)
Cluster lock is required for 2-node configurations
Cluster lock must be powered independently of the cabinet.
Root volume mirrors must be on separate power circuits.
Dual power connected to independent power circuits is highly recommended.
