Description
Although a one-member group is fully functional, adding
more arrays expands capacity, increases network bandwidth,
and improves overall group performance, with no disruption
to data availability.
With multi-member groups, you can create multiple pools and
assign members and volumes to the pools for a tiered storage
solution.
You may want a separate management network for security
purposes.
Snapshots are point-in-time copies of volume data that can be
used for backups.
Schedules enable you to regularly create snapshots or replicas
of a volume.
Collections enable you to group multiple, related volumes for
the purpose of creating snapshots or replicas. The
administrator can then create a multi-volume snapshot or a
multi-volume replica in a single operation or through a single
schedule.
Some environments can benefit from thin provisioning, which
enables you to allocate space to a volume according to usage
patterns.
Replicas are point-in-time copies of volume data that are
stored on a different group.
Cloning creates a new volume in the group.
There are various options for recovering data from snapshots
or replicas.
