Hi: I'm managing a pretty small TSM installation with 4 RS/6K machines (2 6M1 and 2 6H1) running AIX 4.3.3 (ML9). TSM software consists of the server (running in a 6M1 - 7Gb RAM), and the clients running in the same machine and on the others.
I�ve got the following situation: - the total of data backed up is about 200Gb's, - 4 servers are connected using gigabit ethernet links (and have 6Gb RAM and 7Gb RAM each model 6H1 and 6M1 respectively) - TSM uses a storage pool of 240Gb on FastT500 disks (those are connected by FC channels) - TSM uses a 3581 library (LTO) with 1 drive, The fact is (for the same set of information): When I do an archive backup operation with TSM, the time elapsed rounds 5 hours (TSM writes "right to" the tape). When I do an incremental backup operation, TSM uses about 6:30hs for it (TSM writes to storage pool). I'm looking for a rational approach to solve this "problem": isn't it more fast writing to storage pool (disk) that to tape? Anyone had the same performance problem? Is it really a performance problem? I would like some commentaries about this, I can provide some info about the configuration of TSM and the AIX servers. Regards Ignacio
