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 MB 
in physical storage, and includes copypool data.  This are actual numbers that 
do not jive with your calculations.

My environment could be up to 25TB and 625,000,000 files. According to the
TSM 4.2 Admin Guide to calculate the size of my DB I multiply that by 600
bytes..

625,000,000 * 600 = 375,000,000,000 bytes = 375,000,000 KB = 375,000 MB =
375 GB

There also needs to be an offsite copypool of this data.. According to the
TSM 4.2 Admin Guide:

625,000,000 * 200 = 125,000,000,000 bytes = 125GB

So my DB needs to be 500GB, yikes..

How big can one scale a single TSM server installation up to before you need
to start thinking about additional TSM servers? I.e. in this instance can my
TSM server even handle this amount of data? How much could it handle?
