Lawrence, you're calculations are off a little bit.  You're saying that
you have 22,760,941 files, while Gerald is saying he has 625,000,000...
factor of ~27... 27*12 = 324GB.  (Even at 66% utilization, 324GB is a
bit big for a TSM database.)

Gerald, you're probably going to need to look at multiple TSM servers,
which isn't as bad as it used to be.  With the Library Sharing/Drive
Sharing/Scratch Pool Sharing features that were introduced in 3.1+, you
should be able to avoid some of headaches that mutliple servers used to
involve  (servers sharing a 3494 stomping over each others tapes,
anyone? ;-)
