Dell supply them with a 64meg cache and are hardware raid, I have always just installed FreeBSD on them and only 1 hard drive comes up as RAID should be. I have only been ordering the machines in dual drive mirror 1 Raid, but you could get a PowerEdge Tower servers like the 830 which do raid 5, I never used one though. Alternatively all the Dell SCSI RAID systems have 256megs cache which use the LSI Logic MegaRAID ( man amr ) Stay away from the ultra low end SC1425 systems they have some kind of software based raid. The thing I have noticed is that if you compare other (often claiming to be much cheaper) servers from other companies they often really skimp on their hard drive subsystems with software based stuff claiming its RAID. I used to be anti Dell and build my own U1 servers from case and up and had a keen interest in cheap RAID technologies but I gave up a little while ago. I believe Dell are great value when you consider their RAID implementations and as long as you are happy with Intel chips.
