Figure 29 Containment Model: PS Series Storage and FS Series NAS Reserve

The addition of the FS Series NAS appliance to a PS Series group does not change the functional

behavior of PS Series groups and pools. PS Series groups and pools are explained in more detail in

sections 3.1 and 3.2 on page 22.

6.3 NAS File Systems

To provision NAS storage, you need to create NAS file systems within the NAS service. Inside a NAS File

System you can create multiple CIFS shares and/or NFS exports. Access to all shares and exports is

through a single NAS service IP address.

You can create a single large file system, or you can create many separate file systems (a maximum of

256 files systems can be created per FS7500 appliance, 512 max per cluster). You can apply different

backup, snapshot, security, and quota policies to each file system. Creating multiple file systems gives

you the flexibility to apply different management policies to different file systems. The number and

size of the file systems in a NAS service depends on the storage needs of your NAS clients and

applications. You can increase and decrease the size of file systems as needed. The relationship

between the NAS Service, NAS Reserve, NAS File Systems, CIFs shares and NFS exports is shown in

Figure 30 below. Note that you can setup “mixed protocol” access to portions of a file system. This

means that the same portion of the file system can be simultaneously mounted by NFS clients and

mapped by CIFs clients.
