I've seen whitepapers from MySQL's web site, co-authored with Dell, that recommend the hardware optimization be:
1. More Memory 2. Faster Drives (15K RPM is better the 10K) 3. Faster CPU. Based on this, we're spec'ing 2950s with 16Gb, dual 2.8 dual-core Xeons, and 146Gb 15K (times 6) drives. The plan is to RAID then 2 x RAID1 for the o/s (/boot, /, /var, and some working space for dumps and restores), and 4 x RAID10 for /data. Anyone have any feedback on this?
