Virtualization Terms
• VDI
• Stands for Virtual Desktop Infrastructure. VDI is the
hosting of a desktop OS within a Virtual Machine
running on a centralized server.
• Thin Client
• A computer that depends heavily on some other
computer or server. They have a “full” OS on them so
they can connect to the host machine.
• Zero Client
• A computer that does not have a full OS. The kernel is
responsible for networking and displaying the video.
Benefits
• Longer End of Life for the end user devices.
• Lower TCO over time, not typically initially
• Buy processing power and memory as needed
rather than purchasing it up front
• Centralization of hardware
• Ability to add redundancy
• Lower support cost and time spent on
troubleshooting
• Power Savings with Thin/Zero Clients
Challenges
• An error or failure could affect some to all
users in environment.
• Network traffic bandwidth and management
may be needed on your network
• Software Compatibility and Support
• Software Licensing

• http://www.ncomputing.com
• X Series
– PCI Card
– Up to 11 Users on
a single computer
– $399.99 for the
X550 device
• Low Cost
• Shared Computing
• No Microphone or USB Port for Flash Drives
• U Series
– Similar to the X series, but rather than CAT5 cables to a PCI
card, no PCI card and plugs directly in USB ports
– USB
– Up to (10?) users on a single computer
– ~$89.99 for each U170 device
– Low Cost
– Shared Computing
• Microsoft Licensing for nComputing Devices
– http://www.ncomputing.com/WindowsMultiUserLicensing
• L Series (L300)
– Network to a shared computer/server
– Numo SoC (System-On-Chip) - link
– L300 runs on Windows XP and Windows 2003
currently
– Up to “30” per shared Server/PC. The number
really depends on the workload/tasks.
– ~$223.99 for the L300 device
• MultiPoint Server
– Similar to the nComputing X Series
– Website

– Video
• http://www.microsoft.com/windows/multipoint/learnmore.aspx
• HP also has something similar to this product
as well
• http://www.vmware.com/products/view/
• Not a shared computing environment. Each user
has their “own” desktop
• PCoIP (PC over IP) protocol
– There are different elements on a screen (Icons,
Motion Video, Text, Photos, Graphics). The protocol
adapts to what is on the screen and optimizes
bandwidth and the user experience.

• XenDesktop
– HDX (High-Definition User Experience)

– Licensing Challenges
• www.panologic.com
• Zero Client
• Works with both VMware and Hyper-V
• Wyse WSM
• Website and Video
– http://www.wyse.com/products/software/wsm/in
dex.asp
• Requires hardware at end user station
• Server hardware is mainly disk accesses and
streaming over the hard drive
Microsoft Licensing for VDI
• http://www.microsoft.com/virtualization/en/
us/products-desktop.aspx
• Beginning July 1, 2010, Windows Client Software Assurance
customers will no longer have to buy a separate license to
access their Windows operating system in a virtual desktop
infrastructure (VDI) environment. Virtual desktop access rights
will be included as a Software Assurance (SA) benefit.
Tips before switching to VDI
• Test, Test, Test!
– You need to test software and ideally, have it
tested in the environment it will be in. All because
a program runs does not mean it works fully.
• Understand Hardware and Software Licensing
costs.
• Make sure software vendors will offers
support in VDI
