Have you tried placing multiple disk STU's in a new v4.5 Storage group?

The disk spanning is not available in Netbackup 3.4 or 4.5. The only
solution is to create a very large filesystem.
I have few servers with 10 TB filesystems each for disk backup.
You don't need to use multiplexing for disk backup.
The number of streams per clients depends on client hardware and load. I
have six jobs per client.

Thanks,
Alex
