Term Available Space Oversubscribed Space Snapshot space Data Reduction Savings Description Storage space that is physically available for the NAS container. The available space for a NAS container is the amount of unused NAS container space (reserved and unreserved), provided that the NAS reserve has free space. A portion of a thin-provisioned NAS container that is not available and not in use by the NAS container. The overcommitted space for a NAS container is the amount of space allocated (not necessarily reserved) to thinly provisioned containers that exceeds the available NAS reserve free space. With thin provisioning enabled, storage space is consumed only when data is physically written to the NAS container, not when the NAS container is initially allocated. This difference means that more storage space can be allocated for the NAS container than has been allocated to the NAS container itself. Storage space occupied by snapshots of a NAS container. Storage space reclaimed as a result of data reduction processing. About NAS Containers To provision NAS storage, you can create multiple NAS containers in a NAS cluster. In a NAS container, you can create multiple SMB shares and SMB home shares and NFS exports. Access to shares and exports is through one or more NAS cluster virtual IP addresses. The number and size of the NAS containers in a NAS cluster depend on the storage needs of your NAS clients and applications. You can increase or decrease the size of a NAS container as needed without disruption to the NAS clients accessing the NAS container. In addition, NAS containers: • Have robust security mechanisms • Support user and group quotas • Support snapshots for data protection • Support thin clones • Support NDMP for remote backups • Support replication to remote FS Series NAS clusters for disaster tolerance • Support thin provisioning You can create a single, large NAS container, or you can create many NAS containers. Creating multiple NAS containers enables you to apply different management policies to the NAS containers, as required by your organization. For example, you can apply different backup, snapshot, security, and quota policies to the NAS containers. When you create a NAS container, SMB share, SMB home share, or NFS export, the NAS cluster applies default values. Enable Thin Provisioning on a Container To enable thin provisioning on a container: 1. Select the NAS container. 2. Click Modify Settings. 3. Click the Space tab. 4. Select the Thin Provision checkbox. 5. Move the slider (arrow below gray bar) to adjust the space reservation values. 6. Click OK. 210 NAS Container Operations

Term
Description
Available Space
Storage space that is physically available for the NAS container. The available space for a NAS container is
the amount of unused NAS container space (reserved and unreserved), provided that the NAS reserve has
free space.
Oversubscribed
Space
A portion of a thin-provisioned NAS container that is not available and not in use by the NAS container. The
overcommitted space for a NAS container is the amount of space allocated (not necessarily reserved) to
thinly provisioned containers that exceeds the available NAS reserve free space. With thin provisioning
enabled, storage space is consumed only when data is physically written to the NAS container, not when the
NAS container is initially allocated. This
difference
means that more storage space can be allocated for the
NAS container than has been allocated to the NAS container itself.
Snapshot space
Storage space occupied by snapshots of a NAS container.
Data Reduction
Savings
Storage space reclaimed as a result of data reduction processing.
About NAS Containers
To provision NAS storage, you can create multiple NAS containers in a NAS cluster. In a NAS container, you can create multiple SMB
shares and SMB home shares and NFS exports. Access to shares and exports is through one or more NAS cluster virtual IP
addresses.
The number and size of the NAS containers in a NAS cluster depend on the storage needs of your NAS clients and applications. You
can increase or decrease the size of a NAS container as needed without disruption to the NAS clients accessing the NAS container.
In addition, NAS containers:
Have robust security mechanisms
Support user and group quotas
Support snapshots for data protection
Support thin clones
Support NDMP for remote backups
Support replication to remote FS Series NAS clusters for disaster tolerance
Support thin provisioning
You can create a single, large NAS container, or you can create many NAS containers. Creating multiple NAS containers enables you
to apply
different
management policies to the NAS containers, as required by your organization. For example, you can apply
different
backup, snapshot, security, and quota policies to the NAS containers.
When you create a NAS container, SMB share, SMB home share, or NFS export, the NAS cluster applies default values.

1.
Select the NAS container.
2.
Click
Modify Settings
.
3.
Click the
Space
tab.
4.
Select the
Thin Provision
