Option Description Fill In Your Value Here
Use native NFS snapshots
(VAAI)
(Available only if you do not use Virtual SAN) If
your deployment includes NAS devices that
support the vStorage APIs for Array Integration
(VAAI), you can use native snapshot technology
to clone virtual machines.
You can use this feature only if you select
datastores that reside on NAS devices that
support native cloning operations through
VAAI.
You cannot use this feature if you store replicas
and OS disks on separate datastores. You cannot
use this feature on virtual machines with space-
efficient disks. VAAI is not supported on
machines that are virtual hardware version 9 or
later, because the OS disks are always space-
efficient, even when you disable the space
reclamation operation.
This feature is supported on vSphere 5.0 and
later.
For details, see “Using View Composer Array
Integration with Native NFS Snapshot
Technology (VAAI),” on page 198.
Reclaim VM disk space (Available only if you do not use Virtual SAN)
Determine whether to allow ESXi hosts to
reclaim unused disk space on linked clones that
are created in space-efficient disk format. The
space reclamation feature reduces the total
storage space required for linked-clone desktops.
This feature is supported on vSphere 5.1 and
later. The linked-clone virtual machines must be
virtual hardware version 9 or later.
For details, see “Reclaim Disk Space on Linked-
Clone Virtual Machines,” on page 196.
Initiate reclamation when
unused space on VM exceeds:
(Available only if you do not use Virtual SAN)
Type the minimum amount of unused disk
space, in gigabytes, that must accumulate on a
linked-clone OS disk to trigger space
reclamation. When the unused disk space
exceeds this threshold, View initiates the
operation that directs the ESXi host to reclaim
space on the OS disk.
This value is measured per virtual machine. The
unused disk space must exceed the specified
threshold on an individual virtual machine
before View starts the space reclamation process
on that machine.
For example: 2 GB.
The default value is 1 GB.
