NOTE: Although you can use the Group Manager to create storage containers, Dell recommends that you use the Dell
Virtual Storage Manager (VSM) to perform this task. The VSM procedures for setting up VVols is simpler than using the
Group Manager. Using the Group Manager for VVol operations is recommended for experienced users only.
For detailed information about setting up VVols using VSM, see the Dell Virtual Storage Manager for VMware Installation and User’s
Guide.
Volume and Snapshot Space Panel
NOTE: When viewing synchronous replication (SyncRep) volumes, the panel displays the volume space, snapshot space,
and volume distribution graphs for the pools of the SyncActive and SyncAlternate volumes. The SyncActive volume is the
one to which iSCSI initiators connect when reading and writing data. The SyncAlternate volume is the one to which the
data being written on the SyncActive volume is being simultaneously written. If the volumes are in sync, these graphs
display the same capacities. If the volumes are out of sync, the graphs show dierent capacities.
Table 538. Volume and Snapshot Space Panel
Field Description
Storage pool Indicates the storage pool in which the volume resides. If synchronous replication is
enabled for the volume, the pools of the SyncActive and SyncAlternate volumes are
displayed.
Volume space
Reported size Size of the volume in MB, GB, or TB.
NOTE: Volume capacities displayed in the Group Manager GUI can be rounded up
by as much as 15MB. This behavior is normal, and is the result of the array’s
internal calculations for capacity allocations.
Thin provisioning Indicates whether thin provisioning is enabled or disabled for the volume. If enabled, the
volume reserve is equal to or less than the reported size, depending on volume usage and
the thin-provisioning settings. If disabled, the volume reserve is equal to the reported size.
TP warning mode Displays how the volume will respond if the space on the thin-provisioned volume exceeds
the warning limit. Set to either:
leave online
generate initiator write error
both
neither
Volume reserve Actual amount of pool space that the group has allocated to the volume. The amount of
the volume reserve depends on whether you enable thin provisioning on the volume.
Graph of volume space Graph comparing in-use, free, and unreserved space
Snapshot space
Snapshot reserve Snapshot reserve, expressed in capacity (MB or GB) and as a percentage of the volume’s
reported size
Space recovery Indicates whether to delete the oldest snapshot or set the volume oine when the
snapshot reserve has been reached
Number of snapshots Number of snapshots of the volume
Graph of snapshot space Graph comparing in-use, free, and borrowed snapshot reserve space
