Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Although the recommended CP server configurations use three coordination

points, you can use more than three (must be an odd number) coordination points

for I/O fencing. In a configuration where multiple application clusters share a

common set of CP server coordination points, the application cluster as well as

the CP server use a Universally Unique Identifier (UUID) to uniquely identify an

application cluster.

Figure 7-5 displays a configuration using three CP servers that are connected to

multiple application clusters.

CP servers hosted on a single-node VCS cluster

(can also be hosted on an SFHA cluster)

application clusters

(clusters which run VCS, SFHA, SFCFS, SVS, or SF Oracle RAC

to provide high availability for applications)

Figure 7-6 displays a configuration using a single CP server that is connected to

multiple application clusters with each application cluster also using two

coordinator disks.
