To the system administrator, the Sun Cluster product is a set of Solaris hosts that share storage devices.
The system administrator sees software that performs specific tasks:
Specialized cluster software that is integrated with Solaris software to monitor the connectivity between Solaris hosts in the cluster
Specialized software that monitors the health of user application programs that are running on the cluster nodes
Volume management software that sets up and administers disks
Specialized cluster software that enables all Solaris hosts to access all storage devices, even those Solaris hosts that are not directly connected to disks
Specialized cluster software that enables files to appear on every Solaris host as though they were locally attached to that Solaris host
