To protect against outages at a system or data-center level, we recommend using replication to a remote site. This use case includes planned maintenance events, unplanned power outages, or natural disasters. PowerStore supports replication to simplify disaster recovery for block resources. Starting in PowerStoreOS 3.0, file resources are also supported for replication. In PowerStoreOS 3.0, PowerStore appliances support native metro volume replication, which provides synchronous replication of spanned block storage volumes across two PowerStore clusters in metro distance for VMFS datastores. For details on how to set up and use the replication features on PowerStore, see the white papers and on the .
