+ + + VMWare VAAI and Microsoft ODX acceleration in CTL + + + + + Alexander + Motin + + mav@FreeBSD.org + + + + +

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..

+ +

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.

+ +

Microsoft ODX includes support for these SCSI commands: + POPULATE TOKEN/WRITE USING TOKEN (SPC-4 extensions of + XCOPY), WRITE SAME and UNMAP.

+ +

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.

+ +

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.

+ + + + iXsystems, Inc. + + + + +

Full support for thin provisioning, including capacity + usage reporting and thresholds notifications.

+ + +

Inter-host XCOPY operations.
