Hello,
Kindly refer the Hardware compatibility List to check if the version is supported:
Symantec Backup Exec for Windows Servers (tm) 11d (11.0) Hardware Compatibility List. Includes HCL information for supported drives, libraries, virtual tape devices, fibre-channel HBAs, switches, routers/bridges, VSS, NDMP and iSCSI components. For printing purposes, the latest version of Acrobat is recommended.
