I see the exact opposite of what you describe. With the dell 'virtual disk' SCSI disk device under a "SAS 6iR integrated workstation controller, there is nothing visible from any piece of HW that shows me the individual parts

You never so much as hinted that you where talking about SAS i.e. SCSI onboard devices. I thought we were talking about the *much* more common SATA RAID on consumer level motherboards and with those you will see what I wrote a number of times.

I thought SATA devices were moving toward SAS? Most of the disks I have hooked up to my SAS controller ARE 7.2K SATA's. Among the disks, only 3/32 devices are really SAS drives, so the detail that it's a SAS controller isn't something normally first and foremost on my mind. It's a very small cost difference to get a SAS controller that handles both types of drives vs. a SATA-only controller that is far more limited. I'd be surprised if many modern machines don't have some inexpensive option for upgrade. Dell doesn't offer a SATA-only based workstation controller for their workstations or servers. It would take too much work to cripple it enough to save <1% on some configs (they do offer SATA only configurations, just not SATA-only controllers in their workstation line (for the past 12+ years). So it never occurred to me that I'd even need to mention such. Sorry. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
