Yes, jumbo frames, no irq coalescence, blockio and see if you can get Backup Exec to use large io request sizes when reading and writing the data. The larger the better.

Ok, Jumbo's enabled on the switch and media server. For the sake of our sanity jumping back and forth, I am trying to enable jumbo's on the bonded pair in the target, # ifconfig bond0 mtu 9014 and it errors out? Any idea what I am doing wrong?

Yeah, it's MTU 9000 on Linux, Linux adds 14 byte ethernet frame by default (standard MTU is actually 1514).

Also, where do I tune irq coalescence?

It can be done through ethtool if the cards are supported, or sometimes it needs to be done on mod load. Which card?
