  • For the ETERNUS DX600 S6: 768 TB

  • For the ETERNUS DX900 S6: 1 PB

  • For the ETERNUS DX8900 S6: 1 PB

*1  :  To change the total TFOV capacity with CLI, use the "max-tfo-capacity" parameter for the CLI command "set storage-cluster-license". To change the total TFOV capacity with ETERNUS SF Storage Cruiser, refer to the manuals provided with ETERNUS SF Storage Cruiser.

Virtual Volume

Session ID

An identification number (0 to 1999999) for users who are logged in is displayed.

A session ID is obtained for each login and released with each logout. Because the session ID is obtained discretely, the same session ID is not used even if the same user logs in again.

The following shows the range of session IDs to be used.
