The docs say it can take up to 36 R10k processors and 16GB Ram, but
that requires the third card cage which I don't have. I have 15 Ebus
slots to fill, so it will be either lots of CPU's and less memory or
more memory and less processors (until I can afford 2GB MC3's).
Their is a good chance I will use one of the 4xR10k boards in an Onyx
instead (4xR10k, 512MB, IR, MCO should make a nice machine).

Well, I am VERY lucky, they are charging me a flat rate for power and
it's _REALLY_ low, so I hope to be able to run the machines 24/7.

Nope, just two. it only has two disks in it now, but it will get more
in the future at which point I will pick up a third PS. It does have
4x300MHz processors and 1GB Ram now. I am still figuring out Solaris,
so it isn't used much.
