+- eNAS ``nas_quotas`` should not be confused with OpenStack manila quotas.
+ The former edits quotas for mounted file systems, and displays a
+ listing of quotas and disk usage at the file system level (by the user,
+ group, or tree), or at the quota-tree level (by the user or group).
+ ``nas_quotas`` also turns quotas on and off, and clears quotas records
+ for a file system, quota tree, or a Data Mover. Refer to VMAX eNAS CLI
+ Reference guide on `EMC support site <http://support.emc.com>`_ for
+ additional information.
+ ``OpenStack manila quotas`` delimit the number of shares, snapshots etc.
+ a user can create.
