Sun Cluster 3.2 Release Notes for Solaris OS

Sun Cluster Quorum Server

A new quorum device option is now available in the Sun Cluster software. Instead of using a shared disk and SCSI reservation protocols, it is now possible to use a Solaris server outside of the cluster to run a quorum-server module, which supports an atomic reservation protocol over TCP/IP. This support enables faster failover time and also lowers deployment costs: it removes the need of a shared quorum disk for any scenario where quorum is required (two-node) or desired. See Sun Cluster Quorum Server User’s Guide for more information.
