A Veritas Cluster Server (VCS) global cluster links clusters at separate locations and enables wide-area failover and disaster recovery. A global cluster configuration enables disaster recovery of business-critical applications from the production site to a geographically distributed disaster recovery (DR) site, and is recommended when:

  • The distance between the two sites exceeds 80 KM or 50 miles
  • The application data is made available at the DR site through replication
  • The Application is expected to be active at only one site at any point of time (Active/Passive)

In a VCS global cluster, if an application or a system fails, the application is migrated to another system within the same cluster. If the application is unable to come online in the same cluster or the entire cluster fails, the application is migrated to a system in another cluster based on policy. Clustering on a global level also requires the replication of shared data to the remote site.

Additionally you can configure a global cluster using other Veritas Storage Foundation products:
