Option Description Fill In Your Value Here
Storage Overcommit Determine the storage-overcommit level at which
linked-clones are created on each datastore.
As the level increases, more linked clones fit on the
datastore and less space is reserved to let individual
clones grow. A high storage-overcommit level lets you
create linked clones that have a total logical size larger
than the physical storage limit of the datastore. For
details, see “Set the Storage Overcommit Level for
Linked-Clone Virtual Machines,” on page 208.
NOTE This setting has no effect if you use Virtual
SAN.
Use View Storage Accelerator Determine whether to use View Storage Accelerator,
which allows ESXi hosts to cache common virtual
machine disk data. View Storage Accelerator can
improve performance and reduce the need for extra
storage I/O bandwidth to manage boot storms and
anti-virus scanning I/O storms.
This feature is supported on vSphere 5.0 and later.
This feature is enabled by default.
For details, see “Configure View Storage Accelerator
for Desktop Pools,” on page 212.
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 215.
Reclaim VM disk space (Available only if you do not use Virtual SAN or
Virtual Volumes) 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 213.
