Description
Although a one-member group is fully functional, adding more arrays expands
capacity, increases network bandwidth, and improves overall group per-
formance, 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 can set up a separate management network for security purposes.
Snapshots are point-in-time copies of volume data that can be used for back-
ups.
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-vol-
ume snapshot or a multi-volume replica in a single operation or through a sin-
gle 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.
