Hi Jan, we use CStore with ADSM ( now TSM ) since some years now. 1) I dont think the redundancy ( with a copy ) is possible. We use copy stgpools on DLT ( one tape with big capacity ). 2) There is a 1-2-1 mapping. In our case the TSM db does not seem to grow in an extreme way. We have archived about 500.000 documents and 5000 ( big ) printlists up to now. 3) We also go directly to PWORM - due to legal restrictions. We encounter one problem with this : Its the PREEMPT policy of the TSM server. A restore ( = look at an archived document ) has a higher priority the a backup (= archive a document ) and so preempts the archive session. So put as many drives as possible in your optical library. 4) No additional documentation - but web/email support is ok.

It doesn't look like I can use 2 TSM servers from the documentation that I have seen so far. -What impact will the Commonstored objects have on the TSM DB? Is there a one-to-one mapping or can X CommonStore objects be represented as 1 TSM object through some internal commonstore DB? I am looking for advice regarding the TSM DB growth. -IBM has sold our customer a solution that stores the data directly to optical storage. Any comments? Are you using a disk pool first or are you storing directly to optical storage and/or tape? -Anyone got any better documentation then the manual?
