Andre: we have *TWO* A1000's. Yes we can buy them for <$2000 apiece from www.mce.com. The problem is that SCSI *drives* are expensive -- the A1000 is only good for up to 36GB SCSI drives. So if you do RAID5 with *NO* hot spares that's only 396GB. The local price of Seagate 36GB SCSI drives is about $280 (we don't want to buy drives abroad so we can get good RMA support). So the drives would cost 12x280 = $3360. So the total price is $5360. Basically the drives cost more than the array. Also the A1000 with its lame processor is having trouble keeping up with our application load now (granted we're using RAID5 which doesn't have very good write performance -- but using RAID1+0 would reduce capacity and increase cost even more). Compare this with $3000 for a Promise RM8000 and $120 for Seagate Barracuda IV 80GB hard drives. With RAID5 and 1 hot spare I can get (80x6) = 540GB *and I have a hot spare* for only $4000, and it gets even better if I put 120GB or 160GB IDE hard drives in the thing. As you can probably guess from the price the RM8000 is not some "poor man's crappy RAID solution." It has dual power supplies, 4U rackmount, expandable buffer memory (using ECC DIMM's) up to 256MB.. --- Orlando Andico <[EMAIL PROTECTED]> Mosaic Communications, Inc. _ Philippine Linux Users Group.
