I think you are absolutely right. On all of our servers here, all running various versions of FreeBSD, we've been using SCSI drives for years, which as we all know have the same "problem" that ATA drives have now. The only difference is that with SCSI devices, a mechanism exists to wire-down device names to devices. The only real problem that exists with the new ATA driver is that it doesn't support the same wiring-down for ATA devices. I don't remember who suggested it a couple of days ago, but I thought it was a good idea: to simply extend the wiring-down scheme that we already have to support ATA devices too. He also suggested a more universal device name like drv0, drv1, drv2, etc rather than deliniating between whether the drive is ATA or SCSI...I also think that is a good idea as I don't see any good reason an application should care whether the drive is ATA or SCSI, as long as the functionality is provided does it matter how? Great job Soren, the new drivers are great (although DMA support would make them extra cool :) ) Kelly ~kbyanc@posi.net~ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
