Hi, What type of collocation are you using. Filespace or node?

Believe me, I would if I could. It's a management decision. They want our core critical servers restored as quickly as possible so they've mandated that the offsite pool is collocated. (It's frighteningly easy for a server to be included on the "Critical" list.) The problem remains however, WHY am I seeing 150-160 tapes for the offsite pool ejected from the library every day while there are only 45 or so servers writing to the pool? Is each server's data begin spread over 3 different tapes? If so this is not an effective use of tapes. Not to mention counter productive for reducing the amount of tape mounts required for a restore. What's going on here? Is there any way for me to get this under control? Is this NORMAL behavior? If so perhaps I have some ammunition for my argument against collocating the offsite pool.

We've just moved to one from a manual library. I am having a problem with too many tapes from my offsite pool leaving the library every day when MOVE DRM is run. Our core group of critical servers are going to a collocated pool. The number of nodes using this pool is approximately 45. My problem is that between 150 and 160 tapes are ejected from the library on a daily basis! An equal number of tapes are returning from offsite. I expected that the number of tapes going offsite each day would be approximately equal to the number of nodes using the collocated pool (Plus a few more tapes for the non-collocated copypool and the DBB). Any advice on what I'm doing wrong? I am running TSM 5.2.0.0 on an AIX-RS/6000. I have a 3494 library which is shared with an OS/390 mainframe with 6 3590 drives dedicated to TSM.
