1.
Backup server create the
dedicated virtual tape drives

on
233x for each application server.

2.
VTL head just kicks the backup
job and all the backup data
stream goes directly from
application servers to 233x and
no overheads on VTL server.

3.
Application server can also
have its own volume on the
same 233x system.

Fault Tolerent configuration

When Failed
-
over

233x supports multiple IP addresses, so when failover the remaining
controller takes over the LUN of failed controller to the application
servers.

DAS connection allowed maximum of four connections (don’t need
Ethernet switches).
