Dan,
I've used the Filers both as storage pool volumes for my TSM server and for
filespaces for clients. The connection between the Filers and TSM was 100
MBit dedicated. The connection between the Filer and the clients was 100
MBit switched. Clients connected to TSM via the switched network so data
took two trips through the network, one from the Filer to the client and
from the client to TSM. It was as fast as any other NT backup I've seen.
The TSM component seemed to work fine. I noticed some initial performance
hits but I was really hammering the Filer box as I was setting up the
environment. Once we got into production, performance was as good as
locally attached drives. We have the db, log and storage pool volumes on
the Filer. I didn't think this was going to be good, but it turned out just
fine.
I would say for now, let the client using the storage on the Filer do the
backup to TSM. As technology changes, you can implement that as you see
fit. I believe you'll have adequate performance, especially in a well
designed network.

Subject: Net App backups?
Antbody out there with a Network Appliance filer? How are you doing backups?
Any plans to integrate those backups with TSM? They told us that TSM would
support NDMP sometime soon - but I am still not sure exactly what that would
look like. I gather I would have to connect the filer directly to some tape
drives, which is different from the current model where the TSM server owns
the drives. If its all shared via fiber channel, then maybe I dont care. But
I suspect this is all 6-12 (or more)months away, and we are considering some
NetApp's now.
Thanks - any input would be appreciated.
