Dell DVS Simplified Appliance Reference Architecture
4.1.2
PowerEdge T620 Tower-Based Solution
The PowerEdge T620 stands in the same class
of performance and shares the same hardware
configuration options as the R720; only
delivering it in Dell‖s tower-based form factor.
The T620 tower-based form factor is ideal for
deployments where rack and power resources
are unavailable (small branch offices or remote
locations), or in VDI pilots/proofs of concept
where the appliance location may be
temporary.

Storage
Since VDI-in-a-Box only supports local storage, determining the correct size and type of
disk is crucial. The following table details the methods by which to assume storage
capacity:
Storage
Disk Space
Golden Desktop Images
2x Golden Image size
VM Storage
15% x Image size x #VMs
VDI-in-a-box VM
75GB
Recommended Swap Space
VM RAM size x VM #
Thin clone expansion buffer
10% x Golden Image Size x Number of VMs
Also note that VDI-in-a-Box utilizes linked clones technology to further reduce the
amount of storage required. This means the virtual machine is a copy of the golden
image and in turn, shares virtual disks of the parent clone (i.e., golden image). This is why
the storage required per VM is only 15% of the golden image as opposed to 100%. In order
to provide linked clones, VDI-in-a-box must copy the golden images to each server on
the grid so that linked clones can be created on each host server. Note that the hypervisor
must be configured to utilize thin provisioning in order to take advantage of this 85%
