Reducing And Managing Storage Requirements - VMware VIEW 4.5 - ARCHITECTURE PLANNING EN-000350-01 Manual

VMware View Architecture Planning Guide
If using vSphere 4.1, specify whether to use a Microsoft Sysprep customization specification or QuickPrep

from VMware. Sysprep generates a unique SID and GUID for each virtual machine in the pool.
Specify whether the View desktop can or must be downloaded and run on a local client system.

Reducing and Managing Storage Requirements

Using virtual desktops that are managed by vCenter Server provides all the storage efficiencies that were
previously available only for virtualized servers. Using View Composer increases the storage savings because
all desktops in a pool share a virtual disk with a base image.
Managing Storage with vSphere
n
VMware vSphere lets you virtualize disk volumes and file systems so that you can manage and configure
storage without having to consider where the data is physically stored.
Reducing Storage Requirements with View Composer
n
Because View Composer creates desktop images that share virtual disks with a base image, you can
reduce the required storage capacity by 50 to 90 percent.
Managing Storage with vSphere
VMware vSphere lets you virtualize disk volumes and file systems so that you can manage and configure
storage without having to consider where the data is physically stored.
Fibre Channel SAN arrays, iSCSI SAN arrays, and NAS arrays are widely used storage technologies supported
by VMware vSphere to meet different datacenter storage needs. The storage arrays are connected to and shared
between groups of servers through storage area networks. This arrangement allows aggregation of the storage
resources and provides more flexibility in provisioning them to virtual machines.
With View 4.5 and vSphere 4.1, you can now also use the following features:
vStorage thin provisioning, which lets you start out with as little disk space as necessary and grow the
n
disk to add space later
Tiered storage, which allows you to distribute virtual disks in the View environment across high-
n
performance storage and lower-cost storage tiers, to maximize performance and cost savings
Local storage on the ESX server for the virtual machine swap files in the guest operating system

Each user is assigned a particular View desktop and returns to the same virtual
desktop at each login. Users can personalize their desktops, install applications,
and store data.
The virtual desktop is optionally deleted and re-created after each use, offering
a highly controlled environment. A floating-assignment desktop is like a
computer lab or kiosk environment where each desktop is loaded with the
necessary applications and all desktops have access to necessary data.
Using floating-assignment pools also allows you to create a pool of desktops
that can be used by shifts of users. For example, a pool of 100 desktops could
be used by 300 users if they worked in shifts of 100 users at a time.
