5.5 SAT-2 On-disk data format [Wolford and Elliott]

Jeff Wolford presented SAT-2 On-disk data format, a proposal that has not yet been posted. This topic is a SAT-2 open work item. This proposal deals with storing metadata on the ATA device, potentially accessed by more than one SATL, either concurrently or sequentially. He asked for feedback on the types of metadata that may be stored on ATA devices. There were concerns expressed about doing concurrent (multi-initiator) operations without an atomic ATA update operation. Jeff said they would remove this topic for now as they were more interested in sequential operations. Rob Elliott suggested how this metadata could coexist with DDF disks. There were some concerns that the SAT metadata should not be visible at the DDF level.

Mark Overby noted that he plans to upload SAT-2 revision 1 soon.
