Prerequisites
n
Verify that your vCenter Server and ESXi hosts, including all ESXi hosts in a cluster, are version 5.1
with ESXi 5.1 download patch ESXi510-201212001 or later.
Procedure
1 In Horizon Administrator, complete the Add vCenter Server wizard pages that precede the Storage
Settings page.
a Select View Configuration > Servers.
b On 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 Horizon 7, set up space reclamation for desktop pools.
Configure View Storage Accelerator for vCenter Server
In vSphere 5.1 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 Horizon 7 performance during I/O storms, which can take place when
many virtual machines 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 Horizon 7 deployment.
You enable caching on your ESXi hosts by selecting the View Storage Accelerator setting in the vCenter
Server wizard in Horizon Administrator, as described in this procedure.
Make sure that View Storage Accelerator is also configured for individual desktop pools. To operate on a
desktop pool, View Storage Accelerator must be enabled for vCenter Server and for the individual
desktop pool.
