Figure: Typical VCS campus cluster setup depicts a 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.
Figure: Typical VCS campus cluster setup illustrates a typical setup with disk-based I/O fencing. You can also configure server-based I/O fencing.
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.
