VMware View Persona Management preserves user profiles and
dynamically synchronizes them with a remote profile repository. View
Persona Management does not require the configuration of Windows
roaming profiles, eliminating the need to use Active Directory to manage
View user profiles.
View Persona Management provides the following benefits over traditional
Windows roaming profiles:
With View Persona Management, View dynamically downloads a
user’s remote profile when the user logs in to a View desktop.
View downloads persona information only when the user needs
it.
During login, View downloads only the files that Windows
requires, such as user registry files. It then copies other files to the
local desktop when the user or an application opens them from
the local profile folder.
View copies recent changes in the local profile to the remote
repository at a configurable interval.
During logout, View copies only the files that the user updated
since the last replication to the remote repository.
You can configure View Persona Management to store user
profiles in a secure, centralized repository.
View Storage Accelerator reduces the storage load associated with virtual
desktops by caching the common blocks of desktop images into local
vSphere host memory. Storage Accelerator uses a feature of the VMware
vSphere platform called Content Based Read Cache (CBRC), which is
implemented inside the vSphere hypervisor.
When enabled for the View virtual desktop pools, the host hypervisor scans
the storage disk blocks to generate digests of the block contents. When
these blocks are read into the hypervisor, they are cached in the host
based CBRC. Subsequent reads of blocks with the same digest will be
served from the in-memory cache directly. This significantly improves the
performance of the virtual desktops, especially during boot storms, user
login storms, or antivirus scanning storms, when a large number of blocks
with identical content are read.
