What is the backup window?
CPU may be a little off balance for an IP only implementation (no storage
agents) and depends on how many clients are gigabit.
Have you implmented any vmtune changes?

Subject: TSM and Performance
I'd like to hear from anyone who has dealt with performance issues and TSM
that might be able to tell me if the environment I have is at its limits or
some upgrades might help. What I have is an RS/6000 M80 on AIX 4.3.3 running
TSM, that's all it does.
My TSM environment is such that there are about 160 nodes that back up 6
days a week. The one day, Saturday, is set aside for a monthly is there are
any. There are 2 SAP nodes that each back up 200GB a day. The rest is a
mixture of environments, mostly Win2K, with SQL and Domino and a lot of, you
might say, junk. Co-location is turned on, the DB is 43GB, 47%used.
The library is a 3494 with 10 direct attached fiber 3590's. The computer has
5GB of memory, 2 CPU's, is on a GIG but also has 2 other 10/100/1000 cards
not doing anything at the moment. The local disk, 2 drawers, are spread
across 2 SSA adapters. The TSM DB and log are TSM mirrored, one on each SSA.
The TSM support people made a comment to me over the phone I'm not sure I
agree with. In any case I'd like to get some "real life" feedback from
everyone who has this type of environment and tell me if there is something
I need to do now, or very soon. I have outstanding requests to add nodes but
would like to hold off till I find out if I need additional, CPU's, memory
or just environment changes in TSM to beef this up. With all of the issues I
see with 5.1.5.1 I don't know if it's us or the software at this point.
Didn't seem to see this on 4.2.1.9.
Thanks for the help.
