Data replication is a process in which storage data is duplicated to a remote cluster, which provides an enhanced level of redundancy if the main storage system fails. Replication minimizes the downtime-associated costs of a system failure and simplifies the recovery process from a natural disaster or human error. PowerStore supports asynchronous remote replication for volumes and volume groups. PowerStore asynchronous native replication is supported for NAS servers which contain the underlying file systems in PowerStoreOS versions 3.0 and later, on Unified PowerStore T models. Asynchronous replication of vVol-based VMs is also supported with PowerStoreOS versions 3.0 and later with VMware SRM integration. When a protection policy with a replication rule is applied to a volume, volume group, or NAS server, the related replication session that is created appears in PowerStore Manager > Protection > Replication page as shown in the following figure. You can use this page to monitor, pause, or fail over replication sessions as needed.
