Disadvantage: User mapping is required. A user needs to choose one security style, either NTFS or UNIX, and based on the security style chosen the correct mapping for other users is set.

NAS Volumes Storage Space Terminology

FluidFS Manager displays storage space details for individual NAS volumes and for all NAS volumes collectively. The following table defines terminology used in FluidFS Manager related to NAS volume

storage space.

Term

Size

Used Space

Reserved Space

Description

Maximum size of a NAS volume defined by the storage administrator.

Storage space occupied by writes to the NAS volume (user data and snapshots).

A portion of a thinprovisioned NAS volume that is dedicated to the NAS volume (no other volumes can take the space). The amount of reserved space is specified by the storage administrator. Reserved space is used before unreserved space.

Unreserved Space

Available Space

A portion of a thinprovisioned NAS volume that is not reserved (other volumes can take the space). The amount of unreserved space for a NAS volume is: (NAS volume size) – (NAS volume reserved space).

Storage space that is physically currently available for the NAS volume. The amount of available space for a NAS volume is: (unused NAS volume reserved space) + (NAS volume unreserved space, provided that there is free space in the NAS pool).

Overcommitted Space

Snapshot Space

Data Reduction Saving

A portion of a thinprovisioned NAS volume that is not available and not in use by the NAS volume. The amount of overcommitted space for a NAS volume is: (sum of all the NAS volume space) - (NAS Pool: Used Space) - (NAS Pool: Unused (un- reserved Space).

With thinprovisioning, storage space is consumed only when data is physically written to the NAS volume, not when the NAS volume is initially allocated. This means more storage space can be allocated to the NAS volumes than has been allocated in the NAS pool itself.

Storage space occupied by snapshots of a NAS volume.

Storage space reclaimed as a result of data reduction processing.

Configuring NAS Volumes

Manage NAS volumes and NAS volume alerts.

Adding a NAS Volume

Add a NAS volume to allocate storage that can be shared on the network. When a NAS volume is added, default values are applied for some settings. To change the defaults, you must modify the NAS volume.

1.Click the NAS Volumes tab on the left.

2.Click the All NAS Volumes tab on the top.

The NAS volumes are displayed in the All NAS Volumes pane.
