Joshua,
  Thanks for the feedback. This is REAL close to what we are looking to do.
You mention that 2GB is a good amount and that we could even go to 4GB.  Our
experience at TSM 4.1 revealed MANY memory errors and TSM internal errors.
Hence, my question was posted.  (We are now at a later TSM Server version!)
We are looking at a LARGE pSeries server to handle backups in an LPAR
environment. Again, the question becomes, how much memory should this LARGE
pSeries machine have?
  I am interested in knowing if there is some architectural limit as to how
much memory TSM can use? If that is the case I can easily determine how much
memory we should purchase.  For example: If a TSM Server cannot use more
than 4GB of memory and we intend to utilize 2 LPARS running TSM Server, then
it would not benefit us to install more than 8GB of real memory.  But, if
the architectural limit is 2GB, then we would not benefit by installing more
than 4GB of real memory.
  How much memory should a pSeries have installed in order to run two (2)
TSM Servers?

Hmmmm...
TIA,
