About Array-Based Replication Protection Groups and Datastore
Groups
When you create a protection group for array-based replication, you specify array information and
Site Recovery Manager computes the set of virtual machines to a datastore group. Datastore groups contain
all the files of the protected virtual machines.
You add virtual machines to an array-based replication protection group by placing them in a datastore that
belongs to a datastore group that Site Recovery Manager associates with a protection group.
Site Recovery Manager recomputes the datastore groups when it detects a change in a protected virtual
machine. For example, if you add a hard disk that is on another LUN to a protected virtual machine,
Site Recovery Manager adds the LUN to the datastore group of that protection group. You must reconfigure
the protection to protect the new LUN. Site Recovery Manager computes consistency groups when you
configure an array pair or when you refresh the list of devices.
You can also add virtual machines to the protection group by using Storage vMotion to move their files to
one of the datastores in the datastore group. You can remove a virtual machine from an array-based
replication protection group by moving the virtual machine's files to another datastore.
If your storage array supports consistency groups, Site Recovery Manager is compatible with vSphere
Storage DRS and vSphere Storage vMotion. You can use Storage DRS and Storage vMotion to move virtual
machine files within a consistency group that Site Recovery Manager protects. If your storage array does not
support consistency groups, you cannot use Storage DRS and Storage vMotion in combination with
Site Recovery Manager.
How Site Recovery Manager Computes Datastore Groups
Site Recovery Manager determines the composition of a datastore group by the set of virtual machines that
have files on the datastores in the group, and by the devices on which those datastores are stored.
When you use array-based replication, each storage array supports a set of replicated datastores. On storage
area network (SAN) arrays that use connection protocols such as Fibre Channel and iSCSI, these datastores
are called logical storage units (LUN) and are composed of one or more physical datastores. On network file
system (NFS) arrays, the replicated datastores are typically referred to as volumes. In every pair of
replicated storage devices, one datastore is the replication source and the other is the replication target. Data
written to the source datastore is replicated to the target datastore on a schedule controlled by the
replication software of the array. When you configure Site Recovery Manager to work with a storage
replication adapter (SRA), the replication source is at the protected site and the replication target is at the
recovery site.
