Campus, or "Metropolitan," Shared Storage Cluster

In a campus environment, VCS and VERITAS Volume Manager are used to create a cluster that spans multiple data centers or buildings. Instead of a single storage array, data is mirrored between arrays using VERITAS Volume Manager. This provides synchronized copies of data at both sites. This procedure is identical to mirroring between two arrays in a data center, only now it is spread over a distance. The requirements for a campus cluster are two independent network links for heartbeat, public network connectivity between buildings on same IP subnet, and two storage arrays, each providing highly available disks.
