CIFS Protocol
The CIFS (Common Internet File System) protocol defines a standard for
remote file access from many computers at a time in Windows
environments. This protocol allows users with different platforms to
share files without installing additional software.
Active Directory Support
The DXi4000 supports ADS (Active Directory Services) as well as ACLs
(Access Control Lists). This provides the following benefits:
• Compatibility with CIFS domains - NAS shares are able to join CIFS
domains and use domain authentication.
• Precise control of file system permissions - Administrators can
specify which users and groups can perform what actions.
• Robust administrative support - Administrators have the same
implicit permissions as they do in Windows operating systems.
Note: Windows 2003, Windows 2003 R2, Windows 2008, and
Windows 2008 R2 are supported for Active Directory domain
membership.
Note: When you create a CIFS share, the initial permissions are the
same as the default permissions for a Windows 2003 share
with the addition of an ACE (Access Control Entry) that permits
full access to the share for all authenticated users.
Administrators can choose to remove this full access ACE, set
up custom permissions, or leave the ACL (Access Control List)
as is if the server is set up in a fully trusted environment.
NFS Protocol
The NFS (Network File System) protocol was originally designed by
Sun™ Microsystems and allows all network users to access shared files
stored on computers of different types. NFS provides access to shared
files through an interface called the Virtual File System (VFS) that runs
on top of TCP/IP. Users can manipulate shared files as if they were stored
locally on the user's own hard disk. With NFS, computers connected to a
network operate as clients while accessing remote files, and as servers
while providing remote users access to local shared files. This protocol is
