I found a list of T10 activities just since just Dec. 1, 2008 and it

For those of us that don't live and breath the SCSI spec, is there an
overview site describing what is going on.
I've been working off 08-149r7.pdf. I'm sure that's been superseded by
now.
08-356r4 SBC-3: WRITE SAME unmap bit David L. Black PDF (56608) 2008/12/10
Probably interesting. Haven't read it myself.
This is only a four page proposal - basically, we would use the write
same command with a special unmap bit set to tell the target that it may
(at its option) unmap the blocks. If not, it would in fact have to set
the data to the indicated pattern in the command which I presume would
be all zeros in the normal case.
08-356r5 SBC-3 Thin Provisioning Commands Fred Knight, David L.
Black PDF (387549) 2009/01/15
Fred Knight seems to be the main coordinator of this effort, so yes.
Fred and David Black both have been quite active.
08-149r7 SBC - Thin Provisioning Frederick Knight PDF (281001) 2008/12/08
That's the one I'm working from.
08-149r8 SBC - Thin Provisioning Frederick Knight PDF (281387) 2009/01/09
A newer version ... thought so.
09-011r1 SBC-3 Thin Provisioning Threshold Notification Frederick
Knight PDF (32757) 2009/01/09
Clearly related.
08-149r9 SBC - Thin Provisioning Frederick Knight PDF (353888) 2009/01/15
Even newer version of what I've been working from.
09-012r0 Minutes: CAP - Thin Provisioning 12/4 con-call Frederick
Knight PDF (38063) 2008/12/08
Probably tedious.
08-396r3 SPC-4: Reporting support for all DIF types George Penokie
PDF (85358) 2009/01/14
Unrelated, I would think.
I'd go with 08-149r9 to get a good overview.
