"Desktop Virtualization Appropriateness Assessment"
Desktop Virtualization Appropriateness Assessment Tool Purpose This tool is designed to identify the best and the least appropriate targets for virtual desktops. The tactics provided are a sta organizations seeking to assess the scale of virtual desktop deployment. Instructions 1. Complete questionnaires 1 and 2 in the order that they appear. 2. All input boxes (marked in white) are required in order for Overall Results to appear. 3. The recommendations will be provided in the following tabs: ● Overall Appropriateness: Based on your responses to the questionnaire, the tool will indicate the overall appropriatenes desktops. ● Enablers: This tab will identify factors in your existing infrastructure that could act as enablers in implementing virtual des ● Motivators: The potential pain points that could warrant an investment in virtual desktop infrastructure are identified here Info-Tech Research Group tools and templates are provided for the free and unrestricted use of subscribers to Info-Tech R These tools are intended to supply general information only, not specific professional or personal advice, and are not intend substitute for any kind of professional advice.

On a scale of 1 to 6, where 1 is "strongly disagree" and 6 is "strongly agree," please rate the degree to which t Desk side support takes up significant time and effort. Our application deployment and management needs to be more streamlined. For our organization, end user access to applications needs to be secure. Our corporate data needs to be externally accessible yet secured centrally. We have completed our server virtualization implementation. Our current network infrastructure could easily handle bandwidth requirements to support desktop virtualization. (On average virtual desktop utilize 25-30 Kbps of bandwidth per desktop and can reach peak bursts of up to 150 Kbps per desktop) We have sufficient server capacity to support desktop virtualization. (Conservative estimate is 5 VMs per core. Thus, a 4-socket quad core server could run 80 VMs) We have sufficient storage capacity on our Storage Area Network to support desktop virtualization. (Estimate between 30GB to 40GB per user, depending on requirements) A significant number (> 25%) of our desktops are scheduled for refresh over the next two years. Few end users have specialized requirements (e.g. two-way audio, rich media). Few end users need support for desktop peripheral devices. Most of our end users require access to a full desktop experience (e.g. Windows Vista/XP).

Please provide a whole number in each of the 6 white boxes. The subtotals will populate themselves. Please count each user only once (e.g. If a user is sometimes stationary but often mobile, count them as mobile only). - Stationary users connect using permanent LAN links and Remote users use the same link/device to connect from multiple locations. - Mobile users have significant offline use while traveling, and use wide variety of connections – LAN, WAN, dial-up, public WiFi. # of Stationary or Remote users 13 Number of high-performance users who need local 500 graphics processing (video / graphic designers) 14 Number of knowledge workers (executive staff, 200 professional staff, administrative staff, analysts) 15 Number of process workers and data entry workers (customer service, claims and loan processing, 25 processing reservations, etc) Sub-totals 725 Total number of end users in your organization: 775 Proceed to Results ve in each category.

Benefits of doing this include: - Reduction in desk side support costs - Streamlined application deployment and management - Improved data security and user-proofing If desktop virtualization is deployed, your organization can reap the above benefits. Other benefits that you may realize include the following: - Extended refresh cycles. Virtualizing the desktop can prolong the life of existing desktop hardware. New hardware dep need not be latest and greatest in performance and in some cases can be on thin client hardware. Typically savings is 5 traditional. - What “blue screen of…?”. Virtualized desktops are more reliable (less likely to hang or crash) and if they are brought d restart time is faster than a stand-alone PC. - Fast updates. New desktops operating systems (such as a Windows upgrade) and new productivity apps can be deliv zero downtime to end users. The central deployment means it is a win-win for IT. - Green savings.
