3. In the right pane, click the Protocols tab, and then click Edit Settings. The Edit NFS Protocol Settings dialog box appears.
4. For the Maximum NFS Protocol Supported eld, click the down-arrow and select the version of NFS that you want to use.
The options are NFSv3, NFSv4.0, and NFS v4.1.
5. Click OK.
Setting Permissions for an NFS Export
To assign users access to an NFS export, you must log in to the NFS export using a trusted client machine account and set access
permissions and ownership of the NFS export using the
chmod and chown commands on the NFS mount point.
Accessing an NFS Export
Clients use the mount command to connect to NFS exports on UNIX or Linux systems.
NOTE: The parameters shown in the command lines are recommended parameters. See the mount command manual
page in the respective operating system for more information and other options.
Global Namespace
Global namespace is a virtual view of shared folders in an organization. This feature allows the Administrator to provide a single point
of access for data that is hosted on two or more separate servers.
Global namespace is enabled by default, and can be congured using the CLI. See the Dell FluidFS Version 5.0 FS8600 Appliance CLI
Reference Guide for more information about global namespace commands.
Global Namespace Limitations
• Global namespace is supported on SMB2.x, SMB3.x, and NFSv4.x clients only.
• Global namespace cannot be congured on these volumes:
– NAS volume that reached full capacity
– Replication destination NAS volume (or by any other read-only NAS volume)
• NFSv4 redirection targets support NFSv4 protocol (the remote NAS server supports NFSv4, enabling NFSv4 redirections).
• SMB shares cannot be dened on the redirection folder directly. An SMB share is dened on a local folder that contains the
redirection folder. The redirection folder cannot be dened on SMB shared folder (even when empty).
• Redirection folders cannot be set on non-empty directories.
• NAS virtual volume backup, restore, replication, and snapshot operations are not supported on the remote target data. It is
supported only on the redirection folders (including the redirection data information) that reside inside the local volume data.
• After the NFSv4 or SMB client is redirected to the remote server and establishes the remote connection, the client continues
further communication with the remote server.

Using FTP
File Transfer Protocol (FTP) is used to exchange les between computer accounts, transfer les between an account and a desktop
computer, or to access online software archives. FTP is disabled by default. Administrators can enable or disable FTP support, and
specify the landing directory (volume, path) on a per-system basis.
FTP user access to a le is dened by le permissions. FTP anonymous users are treated as nobody. Access permission is denied or
granted, depending on the le’s ACLs or UNIX access mode. FTP access respects and interoperates with SMB/NFS le permissions:
ACLs, NFSv4 ACLs, UNIX word, SID owner, and UID ownership. FTP access to a le also considers SMB/NFSv4 open le state and
byte-range locks. It breaks oplocks when needed.
