What is the theoretical limit of RAM that can be supported on SLES10?
I want to build a huge server with lots of virtual machines that users can
play with. I want lots and lots of RAM and processors.

On a 64 bit system, 2^64, or a buttload of RAM. There's no way you're
going to find DIMMs for that.
32 bit you can go up to 4GB.
Kernel 2.6.16 supports up to 64GB on 64 bit systems if I remember
correctly, so that'd be your operating limit.

Boy, must be nice to have an unlimited budget :). For what it'd cost to
build a big server though, you might be able to get three little servers
for the same capacity for a grand total less than what you'd pay for the
big server.

:) Ebay is your friend.
I just assembled a 4-way with 4G (system only has 2 slots), 300G
for about $2500 I have comfortably run 5 virtual machines (2xSUSE,
WinSBS2003,WinXP and Solaris) and it's not even breaking a sweat!
At the office, we have a DL585 8way/16GB running ESX Server. But so far
we only have 5 guests.
But even with ESX server, disk i/o stinks... something to keep in
mind.

Well I thought he was talking 8/16way with 16GB of RAM :)

My point is that you can get a LOT of virtual servers on a 4way
box. I'd suspect he can get quite a few on a 16way box, though
the highest I've used with ESX server is 8way. I know our
8way box with 16G cost about $23K.... but that's new of course.
I can't say how far the 8way will go though.. we just haven't
loaded ours yet (still have NICs to purchase, we only have 7
