For an Alpha an enormous amount would be 1GB or more. An Alpha has a higher
memory footprint than a VAX due to the Alpha being a RISC processor. Memory
for an Alpha is relatively inexpensive, though, so that's not a problem.
But again, it all depends on what you are doing. If you aren't running
DECwindows, a database, or supporting a lot of interactive users an Alpha
with 128MB is fine. On the other hand, one of the clusters I manage has
two VAX 7730 systems with 2GB of memory each and the memory isn't going
to waste.
