Peter,

  Just a bit of info. We are running ADSM v3.1.2.50 on OS/390 v2.8 our ADSM
data base is 21GB supporting 152 clients. Total backup files 26,000,000
total archive files 4,000,000. Data base is currently at 50% utilization.
Hope this helps.

I am in the process of moving from ADSM on an AIX system to TSM on OS/390
(I
know, I know). In calculating the database size in accordance with TSM
Implementation Guide (Redbook) for 40 servers with approximately 3.4
million
files with a 60 day retention requirement I get a db size of ~128 GB. This
seems a bit much for me. Currently on the AIX side my db size is 3.7 GB.

Any ideas....
