From PowerStoreOS 3.6 and storage replication adapter version 2.1.0.190, Site Recovery Manager supports cross vCenter migration with PowerStore Metro Volume stretched storage. Metro Volume is an active/active replication that supports recovery point objectives (RPO) and recovery time objectives (RTO) of seconds in migration or disaster avoidance scenarios, (Metro Witness is required for RTO of zero) For best practices regarding Metro Volume (uniform/non-uniform configurations, latency, workload mobility, etc.), see Dell PowerStore: Metro Volume.
Note: Stretched storage is supported only on vCenter Single Sign-On Enhanced Linked Mode environments.
