Four Node SFCFS Cluster Built on Fibre Channel Fabric
Shared storage
Shared storage can be one or more shared disks or a disk array connected either
directly to the nodes of the cluster or through a Fibre Channel Switch. Nodes can
also have non-shared or local devices on a local I/O channel. It is advisable to have
/, /usr, /var and other system partitions on local devices.
Fibre Channel switch
Each node in the cluster must have a Fibre Channel I/O channel to access shared
storage devices. The primary component of the Fibre Channel fabric is the Fibre
Channel switch.
