so, the backup data is sent across your network to your tape drives?
yes
and the legato indexes are updated by budtools?
yes
The data is sent over-the-wire to the L11000. The L11000 is hung off an E450. The /etc/dumpdates file on the F740s are updated appropriately, and the file history information is kept by BudTool just like all other non-ndmp requests.

hi,
i'd like recommendations for a dlt autoloader to be attached to an f760 and controlled by legato. thanks. --
I've never really been a big fan of hanging a tape stacker off the netapps. We had an F330 with a 5 tape DLT stacker on it and would occasionally drop the F330.
We later upgraded to the F740s and hung a similar stacker on it while parrallel testing for production and it would hang the bus. One of the prior SAs here actually found an article somewhere which said that some stackers, locally connected, had tendencies to hang the bus.
We then started heavily using BudTool's ability to dump ndmp requests over the wire. Since we have the 100mbit trunked interfaces, we bearly scratch network throughput. The only bottleneck we see now, is at the drives. We have 12 DLT7000s in a L11000 stacker and the drives just can't write fast enough.
We're still looking for a product that'll dump ndmp requests over the wire efficiently that's also cost effective.
