There are those of us who have machines that need long cables. One of the boxes I manage has disks that are 15 meters away from the CPU cabinet. If you need to have hundreds of disks, you can't have silly cable lengths. Of course, the next generation box will be all Fibre Channel, but still. Even on my home box, I have a need for greater than 1 metre bus lengths. david To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
