VDI Practical Guidelines and Real Life Considerations Richard Price Virtualization Specialist email@example.com www.virtguy.com (512) 431-7080 Austin, Texas Fly on the wings of technology
Agenda • This will not be a speech on how great VDI is, it’s 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
Desktop Virtualization Prerequisites User State Virtualization Folder Redirection Roaming Profiles Session Virtualization ie. Terminal Services Management Infastructure Application Virtualization Desktop Virtualization
Personal / Pooled Virtual Desktops • Personal Virtual Desktops • One OS image per user • Administrator access, desktop customizable • User state typically part of the image Personal Virtual Desktops • Personal Virtual Desktops • Shared OS images, identically configured • No administrator access • User state temporary (discarded at session end) Pooled Virtual Desktops
True Multi-Monitor Support • Support for multiple screens and resolutions • Support for up to 16 monitors • Multi-monitor support fully configurable by administrator All operations supported locally, work remotely
Audio Enhancements • Audio input and recording • Streams microphone input from the user’s machine to the Remote Desktop. Enables VoIP and voice recognition applications over RDS. • Improved Audio / Video synchronization • Provides an experience closer to using an physical desktop RD Session Host / RD Virtualization Host
App-V for RDS • Isolation of incompatible apps • Fewer RDSH server silos • Clean app state separation • NEW: Now available as part of the RDS-CAL App-V Management Server RD Session Host RD Virtualization Host RD Client

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 one’s 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 Money” • Nothing is more dangerous than a salesman with an ROI calculator. (They get the development teams for ROI calculations from the guys that package bacon.) • Don’t 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 don’t do it; just make sure the benefits you get will justify the costs.
Assessments, Planning and Implementation • Do 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 Desktops • Ask 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 Desktops • Purchase 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.
