Characteristics Of Volumes - HP StoreVirtual 4000 User Manual

Types of volumes
Primary volumes are volumes used for data storage.
Remote volumes are used as targets for Remote Copy for business continuance, backup and
recovery, and data mining/migration configurations. See the HP LeftHand Storage Remote
Copy User Guide for detailed information about remote volumes.
A SmartClone volume is a type of volume that is created from an existing volume or snapshot.
SmartClone volumes are described in

What it means
The name of the volume that is displayed in the CMC. A
volume name is from 1 to 127 characters and is case
sensitive. The volume name cannot be changed. You can
enable and customize a default naming convention for
volumes. See "Setting naming conventions" (page 18)
more information.
[Optional] A description of the volume.
The logical block storage size of the volume. Hosts and file
systems operate as if storage space equal to the volume size
is available in the cluster. This volume size may exceed the
true allocated disk space on the cluster for data storage,
which facilitates adding more storage systems to the cluster
later for seamless storage growth. However, if the volume
size does exceed true allocated disk space, the ability to
make snapshots may be impacted. See
(page 162).
Remote volumes contain no data, since they serve as pointers
to tell the system where to make a copy of a primary
snapshot. Therefore, remote volumes do not have a size.
[Optional] Servers are set up in the management group to
connect application hosts to volumes. Select the server that
you want to have access to the volume you are creating.
If the management group contains more than one cluster, you
must specify the cluster on which the volume resides.
The data protection level indicates the number and
configuration of data copies created on storage systems in
the cluster.
There are six levels of data protection
Network RAID-0 (None)
Network RAID-5 (Single Parity)
Network RAID-6 (Dual Parity)
Network RAID- 1 0 (2–Way Mirror)
Network RAID- 1 0+1 (3–Way Mirror)
Network RAID- 1 0+2 (4–Way Mirror)
