Hi Christoph, If someone else wants to work on this that would be great. I do not plan to work on this because I do not expect that a SCSI zone append command would be standardized by the time we need it. Although there are references to T10 drafts in the UFS standard, since a few months JEDEC strongly prefers to refer to finalized external standards in its own standards. Hence, standardizing zoned storage for UFS would have to wait until T10 has published a standard that supports a zone append command. INCITS published ZBC-1 in 2016, two years after the first ZBC-1 draft was uploaded to the T10 servers. INCITS approved ZBC-2 this month, six years after the first ZBC-2 draft was uploaded to the T10 servers. Because of the long time it takes to complete new versions of T10 standards we plan not to wait until T10 has standardized a zone append operation. Thanks, Bart.
