I remember My point was that NonPC machines tend to have a higher peripherial loads, and better designed hardware. They have things like memory subsystems that support 16-way interleaving and multiple-bit ECC. They are also much lower volume, which pushes up the cost of parts. The setup costs for an ASIC are much the same if you are making 20,000 or a million. > trying to put a generic SCSI drive into an SGI system several years > ago.

They do use a proprietary disk enclosure system, but it is very nice, and we did look at other systems. Equivelent systems weren't much cheaper, and didn't have as good guarantees about long-term replacement part availability. If a system has a design life-time of seven years, you want to be sure you can get spares in 6.5! (You can, of course, stockpile them yourself, but there are non-trivial costs involved with that. ) David scheidt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
