The TrueNAS 9.3 release features improved virtualization support with the addition of new VMware VAAI primitives. The newly added VAAI Block primitives include Write Same Zero to save resources on writes, XCOPY which reduces VM deployment time by having TrueNAS perform large data transfers, and Atomic Test and Set, which increases the number of VMs you can place on a datastore backed by TrueNAS. Also supported is the SCSI UNMAP command, which is used to recover capacity when a VM is moved or deleted.
