Specifies an optional quota limit (in bytes) for the physical
usage of this Storage Domain (View Box).
This quota limit defines a physical limit for size of the data that
can be physically stored on the Storage Domain (View Box), after the data
has been reduced by change block tracking, compression and deduplication.
The physical usage is the aggregate sum of the data stored for this
Storage Domain (View Box) on all disks in the Cluster.
(The usage includes Cloud Tier data and user data.)
A new write is not allowed if the Storage Domain (View Box) will exceed
the specified quota. However, it takes time for the Cohesity Cluster to
calculate the usage across Nodes, so the limit may be exceeded by a small
amount. In addition, if the limit is increased or data is removed,
there may be a delay before the Cohesity Cluster allows more data
to be written to the Storage Domain (View Box), as the Cluster is
calculating the usage across Nodes.
