About disaster recovery scenarios

Storage Foundation offers cost - effective, short-distance disaster recovery with active configurations and long distance replication solutions to effectively manage disaster recovery requirements.

This guide describes how to configure campus clusters, global clusters, and replicated data clusters (RDC) for disaster recovery failover using the following Storage Foundation and High Availability Solutions products:

See the Storage Foundation Cluster File System High Availability Administrator's Guide for more information on configuring SFCFSHA.

See the Storage Foundation for Oracle RAC Administrator's Guide for more information on configuring SF Oracle RAC.

See the Cluster Server Administrator's Guide for more information on configuring VCS.

See the Veritas InfoScale™ Replication Administrator's Guide for more information on configuring VVR.

Table: Key use cases for disaster recovery configurations lists key use cases for campus cluster, global cluster, and replicated data cluster disaster recovery configurations.

Use case description

Recommended disaster recovery configuration

Disaster Recovery of business-critical applications from the production site to a geographically distributed Disaster Recovery (DR) site.

  • Distance between the two sites exceeds 80 KM or 50 miles

  • Application data is made available at the DR site through replication

  • Application is expected to be active at only one site at any point of time (Active/Passive)

Cluster Server HA/DR with global clustering

See How VCS global clusters work.

SFRAC with global clustering

Disaster Recovery of business-critical applications from the production site to a geographically distributed Disaster Recovery (DR) site.

  • Distance between the two sites is less than 80 KM or 50 miles

  • Application data is made available at the DR site through replication

  • Application is expected to be active at only one site at any point of time (Active/Passive)

  • Automatic application failover within a site, automated failover across sites

Cluster Server HA/DR with Replicated Data Cluster (RDC)

See How VCS replicated data clusters work.

Disaster Recovery of business-critical applications from the production site to a geographically distributed Disaster Recovery (DR) site.

  • Distance between the two sites is less than 80 KM or 50 miles

  • Application data is made available at the DR site through remote mirroring

  • Application is expected to be active at only one site at any point of time (Active/Passive)

  • Automatic application failover within a site, automated failover across sites

Cluster Server HA/DR with Campus Cluster

See How VCS campus clusters work.

Storage Foundation for remote mirroring

High Availability of business-critical applications across two geographically distributed sites.

  • Distance between the two sites is less than 80 KM or 50 miles

  • Application data is made available at the DR site through remote mirroring

  • Application is expected to be simultaneously active at both the sites (Active/Active)
