Table 5-3. Worksheet: Configuration Options for Creating a Linked-Clone Desktop Pool
(Continued)
Option Description Fill In Your Value Here
Select Datastores Select one or more datastores on which to store the
desktop pool.
A table on the Select Datastores page of the Add
Pool wizard provides high-level guidelines for
estimating the pool's storage requirements. These
guidelines can help you determine which
datastores are large enough to store the linked-
clone disks. For details, see “Storage Sizing for
Linked-Clone Desktop Pools,” on page 106.
You can use shared or local datastores for an
individual
ESXi host or for ESXi clusters. If you use
local datastores in an ESXi cluster, you must
consider the vSphere infrastructure constraints
that are imposed on your desktop deployment. See
“Storing Linked-Clone Desktops on Local
Datastores,” on page 112.
In vSphere 5.1 or later, a cluster can have more than
eight ESXi hosts if the replicas are stored on
datastores that are VMFS5 or later or NFS. In
vSphere 5.0, a cluster can have more than eight
ESXi hosts only if the replicas are stored on NFS
datastores. See “Configuring Pools on Clusters
With More Than Eight Hosts,” on page 147.
For more information about the disks that are
created for linked clones, see “Linked-Clone
Desktop Data Disks,” on page 119.
Storage Overcommit Determine the storage-overcommit level at which
View Manager creates linked-clone desktops 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
Desktops,” on page 110.
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 145.
