TCO: Savings through desktop virtualization with the
Cisco/Intel/Citrix VDI solution
Cisco/Intel/Citrix VDI solution
ADDITIONAL SAVINGS SHAVE MONTHS OFF PAYBACK TIME
Enterprise requirements, current practices, and choice of delivery models
and client devices can affect the cost model and savings. In a second model, we
calculate additional savings for endpoint device energy and laptop loss (including
theft) remediation. We discuss additional potential for security savings at the
end of this section.
Energy savings. Desktop energy savings come in many forms when using
desktop virtualization. For example, in hosted models, the desktop workload
and its energy demands move from the PC to the data center, allowing the
use of low-energy thin clients. Additionally, with better PC power
management practices and energy-efficient clients featuring Intel vPro™
Technology, IT can also force use of the sleep/standby/hibernate function on
more PCs. For the purpose of this paper, because we are assuming the
repurposing of existing PCs, we include PC energy savings of 6 watts per
client device per year, a savings of a little more than $10 per device per year.

Laptop loss or theft remediation. Improved data security, protection from
viruses and other attacks, and physical security can provide additional
savings. We include security savings related to laptop loss. A 2010 Ponemon
study sponsored by Intel estimated that the cost of a single lost laptop
without confidential data was $4,078, the cost of one with unencrypted
confidential data was $56,165, and the average cost per lost laptop overall
