Hans, I don't believe that 100GB is a "magic" limit. Just doesn't make sense. The TSM server is a very complex thing; there are many factors affecting performance, as others have stated. For the record, we run a 370GB TSM on an HP rp7410 with (8) 875MHz processors and 12GB RAM. This is a Unix (HP-UX) machine. On the weekends, we typically have over 100 backup sessions running at some times, and during those periods, the CPU utilization (all 8 processors) goes to nearly 100%. But, the TSM DB just runs and runs. Others have highlighted expiration problems; due to circumstances beyond my control, we cannot delete anything at the moment, so I don't run any expirations at all. When we start them again (someday soon, I hope), I suspect they will run a long time ):. Although the TSM DB size itself does not appear to be a problem, it does make DB restores (done regularly in Disaster Recovery tests) take quite some time. It can take up to a full day to get my TSM ready to start client restores in DR tests. For that reason, among others, I am planning to split to several TSM DB's... but they will all be hosted on the same physical server.

Apart from he obvious that we have too few tape drives, bottlenecks in our LAN and an old AIX-box, we got a suggestion to add another TSM-server. The reason was that the performance degrades when the TSM-database reaches about 100Gb in size. We find it a little troublesome to add a new TSM server every time we reach 100 Gb, we would rather just buy us a new AIX-box which is 5 times faster. So I ask you if this 100 Gb limitiation really applies. What is your experience with this? Server version 5.2.3.3 Ca. 100 clients. Best regards Hans Chr. Riksheim
