Administration

Procedure
1 In View 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 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
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 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. To operate on a
desktop pool, View Storage Accelerator must be enabled for vCenter Server and for the individual desktop
pool.
View Storage Accelerator is enabled for desktop pools by default. The feature can be disabled or enabled
when you create or edit a pool. The best approach is to enable this feature when you first create a desktop
pool. If you enable the feature by editing an existing pool, you must ensure that a new replica and its digest
disks are created before linked clones are provisioned. You can create a new replica by recomposing the
pool to a new snapshot or rebalancing the pool to a new datastore. Digest files can only be configured for
the virtual machines in a desktop pool when they are powered off.
You can enable View Storage Accelerator on desktop pools that contain linked clones and pools that contain
full virtual machines.
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.
IMPORTANT If you plan to use this feature and you are using multiple View pods that share some ESXi hosts,
you must enable the View Storage Accelerator feature for all pools that are on the shared ESXi hosts. Having
inconsistent settings in multiple pods can cause instability of the virtual machines on the shared ESXi hosts.
