PowerStore offers asynchronous and synchronous replication of block storage (including volume groups) as well as asynchronous and synchronous replication of NAS Servers and its underlying File Systems and NFS Exports as of PowerStoreOS v3.0. In addition, synchronous replication with Metro Volume support was also added as of PowerStoreOS v3.0. Replication is used to transfer data to one or more remote PowerStore clusters. When the remote cluster is in a different location than the local cluster, this feature can help to protect virtual machine data from localized geographical disasters. Replication RPOs and options are set within protection policies (see the following figure).
Note: The document Dell PowerStore: Replication Technologies provides comprehensive information about replication between PowerStore clusters. See this document for more details about replication.
