The Virtues of Desktop Virtualization - Lenovo | US

Virtualization
Virtual Desktop
infrastruCture (VDi)
A server-based solution for
knowledge workers in a
distributed environment.
If your organization requires a myriad of applications used
by knowledge workers based in multiple locations (such as
regional offices or campuses) with a common data center, you
should consider virtual desktop infrastructure (VDI). A recent
development that’s gaining in popularity, VDI is designed to offer
a customizable user experience with the management and
security advantages of server-based models.
As with rDS, computation and storage are centralized, with user
applications and interfaces pushed over a network connection
via remote desktop protocol. VDI also delivers the TCO savings
that result. The major difference is that VDI can offer users their
own complete virtual machines.
As with other server-based models, performance may vary
with applications, distance, and number of users. It is possible
to run multimedia or graphics-rich applications on VDI clients,
but you may need to add media acceleration for those machines
(see the Wyse article on next page).
advanTages
accessible: users can work from any PC client
Customized: fully personalized PC environment
secure: data safe in a remote location (not on PCs)
Manageable: centralized software and image support
portable: easy to move clients to other sites with
adequate bandwidth.
disadvanTages
Mobility: PCs need physical network connection
performance: need more bandwidth as users increase
and to support advanced applications
Cost: deployment requires transition investment
dependence: all clients depend on server to function
Complexity: IT must manage multiple images
seCure ManageD
Client (sMC)
A storage-based solution
for knowledge workers in
a localized environment.
Lenovo’s exclusive secure Managed Client (SMC), and unlike
rDS or VDI, it doesn’t require additional servers or server
infrastructure investment. A storage-based solution, SMC
offers some unique advantages that are perfect for growing
organizations — or anyone looking for an alternative to their
existing virtualization program.
An SMC solution consists of standard PCs connected to a remote
storage appliance. The storage device hosts data and applications,
but the full PCs can utilize their own processors and peripherals to
run video VOIP and graphic applications. Since user data is stored
centrally, it can be easily managed to deliver the low TCO offered
by other virtualization solutions.
unlike server-based solutions, a SMC storage appliance doesn’t
require special power, cooling, or housing: a network closet will do.
And if you need redundancy, simply purchase another storage
appliance — not additional servers, storage, and software.
SMC doesn’t require drastic changes to IT processes, so users
will think they’re using standard PCs. And SMC clients are as much
as 33% more efficient than PCs using internal hard drives. With
Lenovo SMC 2.0 you can keep all your PC power while saying
goodbye to unnecessary energy use and management costs.
advanTages
powerful: run rich apps on full PCs with peripherals
Customized: fully personalized PC environment
secure: data safe in a remote location (not on PCs)
Manageable: centralized software and image support
Convertible: easy to revert client to normal PC
Cost-effective: no server infrastructure investment required
disadvanTages
Mobility: best utilized in a single location
