My environment could be up to 25TB and 625,000,000 files. According to the

Take a look at the list archives for many detailed discussions on this
topic.
For a late Friday email, the largest TSM DB I have worked with is 120GB.
After about 80GB you may start to see performance problems. I would
recommend 5-7 TSM servers for your implementation

Hmm at 66.5% you're using more like 7,820MB of DB space. With 22,760,941
files that's more like (7,820,000,000 / 22,760,941) 343 bytes per file. The

Hi:
We have an assigned capacity on our DB of 11,760 MB, of which 66.5 % is
currently in use. We have 22760941 files, which represent 4953359.67

Lawrence, you're calculations are off a little bit. You're saying that

bit big for a TSM database.)
Gerald, you're probably going to need to look at multi
Actually...it's probably worse than that. That 600 bytes/file refers to
the first copy of the file resident on the TSM server. Each additional
copy takes ~200 bytes.
If you dig back in the archives for this list, you'll finde references
indiacting (I believe) that you should probably "split up"
