Table 10: Advanced Administration Tasks
Add a member to the group
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.
Set up a dedicated management
network
You can set up a separate management network for security purposes.
Create snapshots of a volume
Snapshots are point-in-time copies of volume data that can be used for back-
ups.
Create schedules for snapshots or
replicas
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.
Enable thin provisioning for a vol-
ume
Some environments can benefit from thin provisioning, which enables you to
allocate space to a volume according to usage patterns.
Set up replication across dif-
ferent groups
Replicas are point-in-time copies of volume data that are stored on a different
group.
Clone a volume or snapshot
Cloning creates a new volume in the group.
Recover data from snapshots or
replicas
There are various options for recovering data from snapshots or replicas.
