Prerequisites
n
Verify that your vCenter Server and ESXi hosts are version 5.1 with ESXi 5.1 download patch
ESXi510-201212001 or later.
In an ESXi cluster, verify that all the hosts are version 5.1 with download patch ESXi510-201212001 or
later.
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.
View Composer Array Integration is not supported in pools that are enabled for View Storage Accelerator.
View Composer Array Integration uses vStorage APIs for Array Integration (VAAI) native NFS snapshot
technology to clone virtual machines.
