Additional IP Networking Requirements

•
The environment must be able to support a separate, private network that
connects only the two clustered nodes for the heartbeat connection. The heartbeat
connection allows the nodes of a cluster to verify each other's state and form a
cluster. This connection can be accomplished by using a crossover cable (not
included with the NAS device) between the two NAS devices, by partitioning a
separate virtual LAN at the switch, or by using a physically separate network via
a separate switch or hub. Each node of the cluster should be placed on the same
non-routed subnet for this connection.
•
Compaq recommends setting up the public network as a redundant path for the
heartbeat. This setup, however, leads to increased traffic on the public network.
•
The remaining network segments of each node should be connected to matching
subnets across both nodes.

Storage Networking Requirements

•
Two additional open ports with one on each of the two SAN switches (for a total
of four open ports for clustering) that have access to the same controller pair on
the SAN
•
Two additional fibre channel cables (for a total of four fibre channel cables)

Storage Object Minimum Requirements

•
At least two LUNs (RAID 3/5 RAID), one for each cluster node for file sharing
•
One dedicated mirror set LUN for the cluster quorum disk
The cluster requires shared resources that can be accessed by either node in the event
of a failover. The fibre-based storage associated with a SAN provides such an
environment.
IMPORTANT: The only high-availability configuration that exists is one that uses vertical
striping using only one disk from each storage enclosure in any given RAID array.
