+      <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>
