VMware vCenter Site Recovery Manager (SRM) interacts with the storage arrays by using the Storage Replicator Adaptor (SRA) to discover and replicate storage Logical Unit Numbers (LUNs), or virtual disks, between Disaster Recovery (DR) sites. Also, the SRA interacts with the storage array to provide failover and test failover capabilities to the SRM allowing automated failover between DR sites. SRAs are developed and provided by the storage array vendors.
There are several tasks that you must complete to configure SRM. Some of these tasks are completed only for vSphere Replication (VR) or for array-based replication. If your environment uses both types of replication, consider all tasks, but if not, you may have to only complete a subset of the total possible set of tasks.
The set of tasks are as follows:
If you are using array-based replication, complete the following tasks at both sites:
After you have established the required infrastructure, complete the following steps:
