Supported Protocols

Supported Protocols
The ETERNUS DX supports the CIFS protocol, the NFS protocol, and FTP/FXP. The CIFS protocol and NFS protocol
can be used simultaneously and enable file sharing between clients in which different OSs (such as UNIX and
Windows) are running. CIFS and NFS are client/server protocols that can perform file management such as exclu-
sive control on the NAS side, which allows exclusive control over each file and simultaneous access.

CIFS

The Common Internet File System (CIFS) is a protocol that is used for file sharing in Windows system environ-
ments.
Files on the network can be shared.

NFS

Network File System (NFS) is a protocol that is used for file sharing in Linux or UNIX system environments.
File sharing for NFS can be performed by mounting a shared directory from a client.

FTP/FXP

With File Transfer Protocol (FTP), the shared folder can be accessed. With File eXchange Protocol (FXP), data in
the shared folder can be transferred between ETERNUS DX storage systems.

NAS Volume Management

Thin Provisioning Volumes (TPVs) that are virtual volumes are used for NAS.

User Management

When the ETERNUS DX is used as a file server, access control over shared files is required. If no control is per-
formed, access from any user is allowed.
If a directory service such as the Active Directory service or the LDAP service is used for access control, user man-
agement and group management can be consolidated.

Active Directory Service

The ETERNUS DX supports authentication by an Active Directory domain controller (user management server) in
a Windows Server.
A directory is stored in a file on the server that is called a domain controller and can be accessed from network
applications and services.
Security is maintained by controlling user access through logon authentication and access control over the ob-
jects in the directories. The Active Directory stores user qualification information and access control information.
Users obtain authentication to log on to the network and privileges to access system resources.
Group accounts can also be created and effective management for user access privileges is available.
