To really know if you need a second server, you need to know what your current server is doing. An M80 with 5GB of RAM and 2 drawers of SSA drives should easily handle 1.5 to 2.5 TB/day; the wide variance is a function of the number of db-inserts that occur. Do you know your current backup load?
I am nervous about 5.1.5.1; I will avoid it, for now -- especially since seeing your earlier posts (and Gretchen's) about some issues. Regardless of my concern, you gotta measure your network, CPU and I/O performance on the TSM serve box, along with the current backup traffic -- see summary table and/or dsmaccnt.log for that number. Fastest way for tracking TSM load would be "ServerGraph"; alternatively, you gotta run your own statistics using VMSTAT, IOSTAT, dsmaccnt.log, and summary table select's to quantify what you're currently doing.

Sent: Sunday, November 03, 2002 7:28 PM To: [EMAIL PROTECTED] 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.
