Planning volume types

• Primary volumes are volumes used for data storage.
• Remote volumes are used as targets for Remote Copy for business continuance, backup and recov-
ery, and data mining/migration configurations. See the Remote Copy User Manual 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

Both [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
Primary
disk space, the ability to make snapshots may be
impacted. See
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

creating.
