4. 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.

5. 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

6. 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

8. 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

9. 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 http://www.ncomputing.com/WindowsMultiUserLicensing

10. L Series (L300) – Network to a shared computer/server – Numo SoC (System-On-Chip) - linklink – 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

11. MultiPoint Server – Similar to the nComputing X Series – Website http://www.microsoft.com/windows/multipoint/defaul t.aspx http://www.microsoft.com/windows/multipoint/defaul t.aspx – Video http://www.microsoft.com/windows/multipoint/learn- more.aspx http://www.microsoft.com/windows/multipoint/learn- more.aspx HP also has something similar to this product as well

12. 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. Video - http://www.youtube.com/watch?v=APVP0DUu34c http://www.youtube.com/watch?v=APVP0DUu34c

16. Wyse WSM Website and Video – http://www.wyse.com/products/software/wsm/in dex.asp 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

17. Microsoft Licensing for VDI http://www.microsoft.com/virtualization/en/ us/products-desktop.aspx 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.

18. 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
