====Suggested Spec====
1x Quadcore Xeon @3.0 < ghz or equivalent. (Opteron preferred, if available.)
6x15k rpm, 36g scsi drives
#1 for OS
#1 for swap/px_log file. Ideally we won't be swapping, but the px_log on it's own drive is a huge benefit, or on the OS drive. Huge benefit for heavy-write DB.
#4 for Raid
##Raid 10(mirrored with striping) not Raid 0+1 (striped with mirroring)This is more fault tolerant. [Linky | http://www.bytepile.com/raid_class.php]
#6-8g ram minimum
#Minimal OS install, Postgres and little else.
