Global clusters provide the ability to fail over applications between geographically distributed clusters when disaster occurs. This type of clustering involves migrating applications between clusters over a considerable distance. You can set up HA/DR using hardware-based or software-based replication technologies.
You can set up a primary cluster for replication to a secondary cluster by configuring global VCS service groups and using a replication technology. The database cluster at the secondary site can be a single node cluster. For example, you can have a two-node cluster on the primary site and a two-node or single-node cluster on the secondary site.
You can use one of the following replication technologies:
Veritas Volume Replicator (VVR), which provides host-based volume replication. Using VVR you can replicate data volumes on a shared disk group in Storage Foundation Cluster File System High Availablity (SFCFS HA) or Storage Foundation for Oracle RAC (SF Oracle RAC).
Supported hardware-based replication technologies. Using hardware-based replication you can replicate data from a primary array to a secondary array.
To verify your configuration is supported, review the product requirements and licensing information:
See the Storage Foundation Cluster File System High Availability Configuration and Upgrade Guide.
See the Storage Foundation for Oracle RAC Configuration and Upgrade Guide.
To confirm the compatibility of your hardware, see the current compatibility list in the Veritas Technical Support website:
https://www.veritas.com/support/en_US/article.000126344
SFCFSHA and SF Oacle RAC support multiple third-party replication options.
For current information on third-party replication support:
See: https://sort.veritas.com/agents and select under .
Notes:
Check your vendor's compatibility list for the supported software versions. The support listed above only exists if the host, HBA, and array combination is in your vendor's hardware compatibility list. Check your array documentation.
All arrays must support SCSI-3 persistent reservations.
The Veritas replication agents provide application failover and recovery support to your replication configuration in environments where data is replicated between clusters.
VCS replication agents control the direction of replication. They do not monitor the progress or status of replication. The replication agents manage the state of replicated devices that are attached to global cluster nodes. The agents make sure that the system which has the resource online also has safe and exclusive access to the configured devices.
