Some of the 3ware products will take 8 drives. If you stock it with 75gb drives that is 600gb. If you need more than that, I guess this probably isn't the solution for you. The 3ware cards will do the RAID with IDE. I don't want to start a holy war, but I really see no need for SCSI if you follow a few basic rules with your IDE drives. 1) Get good drives (IBM) 2) Get good controllers (3ware for RAID-10) or Promise cards 3) Keep it at one drive per chain. I am no hardware expert, but it is my understanding that there are major performance hits if you have two drives on a single chain. The performance on with these sort of setups are really good at a great price. # dd if=/dev/twed1 of=/dev/null bs=32k count=40960 40960+0 records in 40960+0 records out 1342177280 bytes transferred in 37.895167 secs (35418165 bytes/sec) This is a fairly heavily loaded system using a 3ware card for RAID-10 and IBM 24GB drives (7200 ata66 I think). # dd if=/dev/ad6 of=/dev/null bs=32k count=40960 40960+0 records in 40960+0 records out 1342177280 bytes transferred in 36.997196 secs (36277811 bytes/sec) This is a system with a Promise ATA100 card and a IBM 75GB ata100 7200rpm drive. ----- Original Message ----- From: "Michael VanLoon" <MichaelV@EDIFECS.COM> To: "'Joseph Gleason'" <clash@fireduck.com>; "Ed Henderson" <Ed.Henderson@Certainty.net>; <freebsd-hardware@FreeBSD.ORG> Sent: Monday, March 26, 2001 15:29 Subject: RE: Server MB suggestions? > I wouldn't recommend building a server with IDE drives, but maybe that's > just me... > > If I were building a production server with performance in mind, I'd go > RAID-10 (or RAID 0+1, depending on what you want to call it -- either way > it's striping without parity, on top of mirrors).
