Preparing For Cluster Installation; Sharing Protocol Cluster Support - HP ProLiant DL380 G5 Administration Manual

In addition, a cluster uses at least two network connections on each node:
• The cluster interconnect or "heartbeat" crossover cable connects to the first network port on
each cluster node. In more than two node deployments, a private VLAN on a switch or hub is
required for the cluster interconnect.
• The client network subnet connects to a second network port on each cluster node. The cluster
node names and virtual server names have IP addresses residing on these subnets.
NOTE:
If the share is to remain available during a failover, each cluster node must be connected to the same
network subnet. It is impossible for a cluster node to serve the data to a network to which it is not
connected.
Protocol planning
The storage servers support many file sharing protocols, including sharing protocols for Windows, UNIX,
Linux, Novell, Macintosh, Web, and FTP clients. However, not all of these protocols can take advantage
of clustering. If a protocol does not support clustering, the share is not available to the clients until
the owner cluster node is brought back online.
HP recommends placing cluster aware and non cluster aware protocols on different file shares.

AppleTalk
NOTE:
AppleTalk is not supported on clustered disk resources. AppleTalk requires local memory for volume
indexing. On failover events, the memory map is lost and data corruption can occur.
