Procedure
1 In
View Administrator, complete the Add vCenter Server wizard pages that precede the Storage Settings
page.
a Select View Configuration > Servers.
b In the vCenter Servers tab, click Add.
c Complete the vCenter Server Information, View Composer Settings, and View Composer Domains
pages.
2 On the Storage Settings page, make sure that Enable space reclamation is selected.
Space reclamation is selected by default if you are performing a fresh installation of View 5.2 or later. You
must select Enable space reclamation if you are upgrading to View 5.2 or later from View 5.1 or an earlier
release.
What to do next
On the Storage Settings page, configure View Storage Accelerator.
To finish configuring disk space reclamation in View, set up space reclamation for desktop pools.
Configure View Storage Accelerator for vCenter Server
In vSphere 5.0 and later, you can configure ESXi hosts to cache virtual machine disk data. This feature, called
View Storage Accelerator, uses the Content Based Read Cache (CBRC) feature in ESXi hosts. View Storage
Accelerator improves View performance during I/O storms, which can take place when many desktops start
up or run anti-virus scans at once. The feature is also beneficial when administrators or users load applications
or data frequently. Instead of reading the entire OS or application from the storage system over and over, a
host can read common data blocks from cache.
By reducing the number of IOPS during boot storms, View Storage Accelerator lowers the demand on the
storage array, which lets you use less storage I/O bandwidth to support your View deployment.
You enable caching on your ESXi hosts by selecting the View Storage Accelerator setting in the vCenter Server
wizard in View Administrator, as described in this procedure.
Make sure that View Storage Accelerator is also configured for individual desktop pools. View Storage
Accelerator is enabled for pools by default, but this feature can be disabled or enabled when you create or edit
a pool. To operate on a pool, View Storage Accelerator must be enabled for vCenter Server and for the
individual pool.
You can enable View Storage Accelerator on pools that contain linked clones and pools that contain full virtual
machines.
View Storage Accelerator is also supported with local mode. Users can check out desktops in pools that are
enabled for View Storage Accelerator. View Storage Accelerator is disabled while a desktop is checked out and
reenabled after the desktop is checked in.
Native NFS snapshot technology (VAAI) is not supported in pools that are enabled for View Storage
Accelerator.
View Storage Accelerator is now qualified to work in configurations that use View replica tiering, in which
replicas are stored on a separate datastore than linked clones. Although the performance benefits of using View
Storage Accelerator with View replica tiering are not materially significant, certain capacity-related benefits
might be realized by storing the replicas on a separate datastore. Hence, this combination is tested and
supported.
