Share Usage Statistics

On the left side of the view (beneath the Project panel when collapsed) is a table explaining the current space usage statistics. These statistics are either for a particular share (when editing a share) or for the storage pool as a whole (when looking at the list of shares). If any properties are 0 (zero), then they are excluded from the table.

Some of the usage statistics are also displayed in the CLI context shares show.

The following table describes the BUI and CLI usage properties.

BUI Name	CLI Name	Description
Available space	--	This statistic is implicitly shown as the capacity in terms of capacity percentage in the title. The available space reflects any quotas on the share or project, or the absolute capacity of the pool. The number shown here is the sum of the total space used and the amount of available space.
Referenced data	usage_data	The amount of data referenced by the data. This includes all filesystem data or LUN blocks, in addition to requisite metadata. With compression, this value may be much less than the logical size of the data contained within the share. If the share is a clone of a snapshot, this value may be less than the physical storage it could theoretically include, and may be 0 (zero).
Snapshot data	usage_snapshots	The amount of space used by all snapshots of the share, including any project snapshots. This size is not equal to the sum of unique space consumed by all snapshots. Blocks that are referenced by multiple snapshots are not included in the per-snapshot usage statistics, but will show up in the share's snapshot data total.
Unused reservation	--	If a filesystem has a reservation set, this value indicates the amount of remaining space that is reserved for the filesystem. This value is not set for LUNs. The appliance prevents other shares from consuming this space, guaranteeing the filesystem enough space. If the reservation does not include snapshots, then there must be enough space when taking a snapshot for the entire snapshot to be overwritten. For more information on reservations, see Filesystem Properties.
Total space	usage_total	The sum of referenced data, snapshot data, and unused reservation.
