For people who are interested, the latest drafts for the SMR
management layer (now called Zoned Block Commands) are available from
the T10.org web site. You can find the latest drafts by going to:
http://www.t10.org/new.htm
and then look for documents with "ZBC" in the title, but the current
set of documents are:
14-010r1 ZBC Proposed Commands Curtis Stevens 2014/01/15
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-010r1.pdf
14-009r1 ZBC model clauses for zone types Curtis Stevens 2014/01/15
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-009r1.pdf
14-007r3 ZBC Model clauses for write and read commands 2014/01/15
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-007r3.pdf
14-005r1 ZBC Initial Outline Curtis Stevens 2014/01/15
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-005r1.pdf
14-025r0 ZBC common model references (clause 4) Gerald Houlder 2014/01/10
http://www.t10.org/cgi-bin/ac.pl?t=d&f=14-025r0.pdf
Documents 14-009 and 14-007 are probably the most interesting to look
at. Also of note is REPORT ZONES command in section 5.3 in document
14-010.
Cheers,
- Ted
