Typical VCS campus cluster setup

VCS campus cluster typically has the following characteristics:

• Single VCS cluster spans multiple sites.

  In the sample figure, VCS is configured on four nodes: node 1 and node 2 are located at site A and node 3 and node 4 at site B.

• I/O fencing is configured with one coordinator disk from each site of the campus cluster and another coordinator disk from a third site.
• The shared data is located on mirrored volumes on a disk group configured using Veritas Volume Manager.
• The volumes that are required for the application have mirrors on both the sites.
• All nodes in the cluster are tagged with the VxVM site name. All disks that belong to a site are tagged with the corresponding VxVM site name.
• The disk group is configured in VCS as a resource of type DiskGroup and is mounted using the Mount resource type.
