Cluster Configuration
Typical cluster configurations normally include a shared disk subsystem
connected to all servers in the cluster. The shared disk subsystem can be
connected via high-speed fiber channel cards, cables, and switches, or be
configured to use shared SCSI. If a server fails, another designated server in the
cluster automatically mounts the shared subsystem volumes previously
mounted on the failed server. This gives network users continuous access to the
volumes on the shared disk subsystem.
Typical resources might include data (volumes), applications, server licenses,
and services. The following figure shows how a typical fiber channel cluster
configuration might look.
Although fiber channel is the recommended configuration, you can configure
your cluster to use shared SCSI. The following figure shows how a typical
shared SCSI cluster configuration might look.
