I'd like to see data which supports this. CPUs have gotten so fast and disk I/O still sucks. All the systems I've seen are CPU rich and I/O starved. The smartest thing you could do would be to get a cheap box with a GB of ram as a disk cache and make it be a SAN device. Make N of those and you have tons of disk space and tons of cache and your 8 way opteron database box is going to work just fine. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm
