+-  eNAS ``nas_quotas`` should not be confused with OpenStack manila quotas.
521
+   The former edits quotas for mounted file systems, and displays a
522
+   listing of quotas and disk usage at the file system level (by the user,
523
+   group, or tree), or at the quota-tree level (by the user or group).
524
+   ``nas_quotas`` also turns quotas on and off, and clears quotas records
525
+   for a file system, quota tree, or a Data Mover. Refer to VMAX eNAS CLI
526
+   Reference guide on `EMC support site <http://support.emc.com>`_ for
527
+   additional information.
528
+   ``OpenStack manila quotas`` delimit the number of shares, snapshots etc.
529
