Replication for Storage Arrays

With the Commvault software, you can create a replica copy of the primary snapshot copy of the local array on a remote array.

You can configure the replication feature with the following vendors, modes, and type of replication.

You cannot re-copy snapshot primary copies or snapshot replica copies.

Vendor	Supported modes	Type of replication	More information
Amazon	Synchronous	Offline
Azure NetApp Files	Asynchronous	Offline
Azure Managed Disk	Asynchronous	Offline
Asynchronous Data Replication for VMware on Nutanix	Asynchronous	Inline	Nutanix
Azure Disk Snapshot	Asynchronous	Offline
Dell EMC Isilon/PowerScale	Asynchronous	Offline
Dell EMC PowerMAX and Dell EMC VMAX	Asynchronous Synchronous	Inline	In synchronous mode, the replica copy is application-consistent, except for the Microsoft Hyper-V Agent. In asynchronous mode, the replica copy is crash-consistent. For the Microsoft Hyper-V Agent, the replica copy is crash-consistent in synchronous and asynchronous modes. For VMAX3 and VMAX All Flash, the replica copy is crash-consistent in synchronous and asynchronous modes. You cannot perform revert operations for the replica copy.
Dell EMC Powerstore	Asynchronous	Offline	You cannot perform revert operations on replica copies. Volume Group Replication is not supported.
Fujitsu ETERNUS AF / DX	Synchronous	Inline
Hitachi Vantara Virtual Storage Platform/Hitachi Unified Storage VSP/HUS-VM using Command Control Interface (CCI) Engine	Hitachi Universal Replicator (HUR) asynchronous replication Hitachi TrueCopy synchronous replication	Inline	The replica copy is crash-consistent. ShadowImage (SI) and Thin Image (TI) of replicated volumes, Dynamic Provisioning Volumes (DP-VOLs) and external volumes (ELUN) are supported. You cannot use the revert operation on either the snapshot copy or on the replica copy. You cannot create a snapshot of a clone.
HPE 3PAR StoreServ / Primera / HPE Alletra 9000 Series / HPE GreenLake for Block	Synchronous Asynchronous periodic	Inline	The primary snapshot and the replica copy are application-consistent. You cannot perform revert operations for the primary snapshot copies or replica copies. You can replicate snapshots between HPE Primera and HPE 3PAR StoreServ and vice-versa. You can perform synchronous replication. From FR 11.20 you can perform synchronous and asynchronous periodic replication.
HPE XP7 and HPE XP P9500	Continuous Access Synchronous Continuous Access Journal	Inline	The replica copy is crash-consistent. You cannot use the revert operation. You cannot create a snapshot of a clone.
HPE Nimble Storage/Nimble dHCI/HPE Alletra 5000 Series/HPE Alletra 6000 Series	Asynchronous	Offline	You cannot perform revert operations for replica copies.
IBM N-Series	Asynchronous	Offline
INFINIDAT	Asynchronous Synchronous	Inline	You cannot perform revert operations for snapshot copies or replica copies. For the Microsoft Hyper-V Agent, the snapshots replicated on the target array are crash-consistent. The primary snapshots are application-consistent.
NetApp Open Replication	Asynchronous	Offline without OnCommand Unified Manager (OCUM)	Read about specific information for Replication for VM-Centric Operations.
NetApp with SnapVault SnapMirror*	Asynchronous	Offline	Read about specific information for Replication for VM-Centric Operations.
Pure Storage FlashArray	Asynchronous	Inline	You cannot perform revert operations for replica copies. For the Microsoft Hyper-V Agent, the snapshots that are replicated on the target array are crash-consistent. The primary snapshots are application-consistent.

Note

You can use the fan-out configuration with the NetApp storage array.
For NetApp FlexGroup volumes, you cannot use the Commvault software with OCUM-based snapshot replication.
For NetApp Open Replication, you can use NetApp Flex Group volumes for two node replication topologies only, for example, either Primary to Mirror, or Primary to Vault. This limitation is because ONTAP does not support three-node replication and does not support fan-out topologies for Flex Group volumes.

*NetApp with SnapVault SnapMirror OCUM-based snapshot replication is not supported for Amazon FSx for NetApp ONTAP.
