That would be quite an investment. Interesting. I wonder if we should put windows or linux on it, since postgresql 8.0 works on windows.
What OS are you running on your quad opteron ?
Well here's one thing that you can bank on. You can get 64-bit Linux now while 64-bit Windows is still beta. (The word is that 64-bit Windows is pretty stable except for the lack of drivers but I'd still feel queazy about spending this much money to run a beta OS.)
And you absolutely want a 64-bit OS with that much memory. Even on our development server with just 3GB of RAM, we see quite big jumps in performance after moving from 32-bit Linux to 64-bit Linux. I'd hate to think about 64GB of RAM being swapped in and out using PAE.
