Those
9940B drives should be good for a 262144 buffer size, unless there's still
some windows limitation....though I believe that limitation was for the built in
windows driver.
you
should be fine with the STK driver, though you'd obviously want to do some
testing.
Can
you get a report of your current disk layout from the disk
fairies?
RAID
layout? Number of spindles? Dedicated RAIDsets? Number of paths? etc,
etc?

Yes, when we speed it up we played with the buffer
settings.
# of buffers is set at 64, size is 32768.
When I started this
6 months ago, they said only professional services could help me. But I
will say that the guy that came in did help, because before it was talking 23
hours to backup. With the multiple streaming of the
information stores, buffer changes,
and installing the STK tape drivers for windows
instead of the Veritas ones, we saw
improvements.
I was talking with
the disk fairies and they are going to relay out the disks for the exchange
servers. They are saying, from what they are seeing, this will also help
with the read performance. I will just have to wait for them and be
patience.
