Fly on the wings of technologyVDI The Good the Bad and the Ugly

This will not be a speech on how great VDI is, its great for some users and lousy for others;

We will discuss the preparation for VDI; How to license the desktops for VDI; & VDI Nitty-Gritties

(as I see it)Do I need a SAN for my VDI Farm?NO! (Unless you go blade route.)DAS will give great performance at much lower cost.Connection broker will balance the loads; no need for shared storage for Vmotion or Live Migration to dynamically balance.A VDI host server failure will cause the desktop to act like it crashed (no ones died from this yet). Log back in and the Broker will find a working machine for you.Design to avoid Boot Storms to avoid crazy expensive Solid State cards.VDI Will Save you MoneyNothing is more dangerous than a salesman with an ROI calculator. (They get the development teams for ROI calculations from the guys that package bacon.)Dont believe them. It will not save you money, it will be at least 15% more expensive than just refreshing your desktops.This doesn't mean dont do it; just make sure the benefits you get will justify the costs. Assessments, Planning and ImplementationDo test studies in your lab environments, you will learn a lot.This is not server virtualization. Virtual server environments have their ups and downs. VDI environments are off the charts manic depressives. Use a VAR/OEM to assess historic workload patterns, plan and design/implement, andcheck their references.

Licensing the DesktopsAsk three different Microsoft people how to licensing anything and you will get three different answers.Two ways to license (independent of Hypervisor choice)Have Software Assurance on DesktopsPurchase VDA Subscription (all thin clients are licensed this way.)VDA Subscription conveys Software Assurance so either option entitles you to Windows Thin PC to reuse old desktops.Remember a new Thin PC will consume about 1/7 the power of a desktop.
