I thought the frameworks created a shim layer between the SATA command set and the SCSI-based, but I could be wrong. So, I thought there was a different command set on the physical device. I may be wrong on that. For me, and I haven't done a lot of experimenting, but SCSI is so much faster for certain operations on Solaris. Some of my systems have SATA that are running in compatibility mode, so that is a bad comparison. I'm going to try and swap a controller around this coming week, so I can move a set of SATA drives to me main workstation at home, it has only SCSI in it now, but the SCSI is great to work on. In general I have much better experiences with SCSI rather than SATA, although SATA always sounds better on paper to me. > In the event that it requires some effort to do, I'll +1 it as a > project. (I am a CC here.) It would be nice if we could get someone from the SATA team to join and work with the community on this, maybe Steve can help by providing some information on the device he has, and put that together with what they may know already. From Alan Perry's response, he might be working on SATA also these days. -- Alan DuBoff - Solaris x86 IHV/OEM Group _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
