+ <p>CAM Target Layer (CTL), used as base for the kernel iSCSI
+ server, got support for VMWare VAAI and Microsoft ODX
+ storage acceleration. It permits avoiding network
+ bottlenecks and improved storage efficiency on sets of large
+ operations, such as virtual machine (or large file) creation,
+ initialization to zeros, copy, delete, etc..</p>
+
+ <p>VMWare VAAI includes support for these primitives/SCSI
+ commands: Atomic Test and Set (ATS) — COMPARE AND
+ WRITE command; Extended Copy (Clone) — SPC-3 subset
+ of XCOPY commands; Write Same (Zero) — set of WRITE
+ SAME commands; Dead Space Reclamation (Delete) &mdash UNMAP
+ command.</p>
+
+ <p>Microsoft ODX includes support for these SCSI commands:
+ POPULATE TOKEN/WRITE USING TOKEN (SPC-4 extensions of
+ XCOPY), WRITE SAME and UNMAP.</p>
+
+ <p>All XCOPY operations are currently limited to one storage host.
+ ODX operations are currently limited only to iSCSI disks.
+ Accelerated inter-host copying or copying to/from files on
+ Samba shares is not implemented and handled by initiators in
+ the legacy way.</p>
+
+ <p>The code is committed to FreeBSD head and stable/10 branches,
+ and will be present in FreeBSD 10.1 and FreeNAS 9.2.1.8 /
+ 9.3 releases.</p>
