Reducing and Managing Storage
Requirements 15
Deploying desktops on virtual machines 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 virtual machines in a pool share a virtual disk with a base image.

Managing Storage with vSphere
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 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.
Compatible vSphere 4.1 or Later Features
With vSphere 4.1 or later, you can now also use the following features:
n
vStorage thin provisioning, which lets you start out with as little disk space as necessary and grow the
disk to add space later
