FTP/FXP

Shared folders can be accessed using the File Transfer Protocol (FTP) and the File eXchange Protocol (FXP).
Up to five shared folders can be published using FTP.
For FXP, data in the shared folder can be transferred between ETERNUS DX storage systems.
For access using FTP and FXP, a user authentication in the authentication servers (Active Directory
authentication servers and LDAP authentication servers) or an account that is registered in the local user
authentication setting is required.

Access shared
folders with FTP
When the user account that is registered in the authentication servers is used for the FTP login, the shared
folders that are published in the home directory can be accessed. Files in the folder can be downloaded and can
be uploaded to shared folders.
Caution
During the operation phase
• Both active mode and passive mode can be used as the connection mode for FTP and FXP.
• A total of 50 sessions can be accessed with FTP and FXP at the same time.
• Volumes for snapshots and backup volumes cannot be accessed with FTP connections.
• Encrypted communications (FTPS/SFTP/FXSP) are not supported.
• If a failover or failback occurs during an FTP, the connection is disconnected and must be reconnected
from the FTP client side.
• For NAS FTP, if a large quantity of small files were written (with a PUT operation) continuously (for
example: tens of thousands of files with tens of KB were written), FTP may be terminated abnormally
according to the OS/FTP tools' specification on the FTP client side.
If FTP is terminated abnormally and an error message (for example: Could not bind the data socket:
Address already in use) is displayed on the FTP client side, continue process after dividing the number of
files.
