The first check you need to do is to see if it's a NetBackup transport limitation.  Do one of the various tests to see if you're reading off the file system fast enough (a backup to the null device is documented in a technote somewhere).

I picked up some Enterprise Client licenses to speed up the backups on
some of my larger database servers. I've gone through the Fiber
Transport guide and setup everything as the guide suggests. When I
fire off my first backup, I'm only getting like 20 MB/s - 30 MB/s.
Those aren't quite the numbers I was expecting. I've gone back through
the guides and checked to see if there's some glaring mistake I've
made and I can't find one.

My question is this: For those of you that use FT, do I need to go
into the OS and change anything on the HBA? Is there perhaps a setting
in the OS or maybe on the firmware of the HBA itself that might be
throttling my SAN bandwidth?

Thanks.
