We currently have 3 servers running the following config: Tyan S2567U3AN mobo 2x Intel 1G Chip 2gig ram escalade 7800, 8 channel *16* WD 80gig drives and two servers running: Tyan S2567U3AN mobo 2x Intel 1G Chip 2gig ram escalade 6800, 8 channel *16* Maxtor 80gig drives All RAID5 All are in cases from rackmountpro.com that have a 450W mini redundant power supply. These servers are slammed pretty hard.. each taking in a full newsfeed etc. No problems at all.. We've lost 3 drives in 4 months, no problems w/ rebuilds. I couldn't be happier w/ the 3ware stuff..
