Businesses of all sizes are seeking to adopt desktop virtualization and gain its benefits to meet challenges such as:consumerization of the workplaceMicrosoft Windows upgradesFrequent and expensive PC refresh cyclesSoftware upgradesBurdensome ongoing support. Employees carry multiple devices to their evolving workplaces for flexibility, but each device has its own desktop that needs to be maintained. Users expect business continuity as they move from one device to another. The ratio of computing devices to employees is growing quickly, especially mobile devices, creating a significantly increased risk of data loss and theft. IT departments have to meet these challenges while facing shrinking budgets, changing priorities, and inadequate personnel skills..Data center managers are being tasked with mitigating this risk. Systems engineers are challenged with administering all the additional devices being added to the network. The increased volume and variety of computing devices has made application upgrades and deployments much more difficult to manage.
Here’s what’s driving this interest in VDI. IT organizations of all sizes must address the consumerization of the workplace, the cost of 3-5 year PC refresh cycles, software upgrades and burdensome on-going support; all while dealing with ever-shrinking budgets, changing priorities and insufficient personnel skillsets.This is why companies implement virtual desktops - the promise of eliminating the inefficiencies and costs of operating and managing PCs, not to mention securing and enabling a wide range of mobile devices to access data from outside the firewall.
At first, PCs look affordable, until you factor in the security issues they introduce; the fact that they are difficult and costly to maintain, manage, troubleshoot and patch; the cost of the power they consume; and the 20+ hours per year they are unavailable to the user. And you get to do a refresh every 3-5 years to keep up with the latest operating system and applications. We hear from customers that PC management is the key reason they are looking at virtual desktops.In a recent visit with Gartner, they said the number of questions they get on VDI far outweighs the questions on any other topic, by about a 3 to 1 ratio – even when compared to subjects like “Cloud” which you would think is pretty hot today. So IT has a big pain-point around desktop management.
VDI is a desktop delivery model that allows users to access full desktop environments including Operating Systems, applications, user settings and data that reside in virtual machines running on centralized servers within the data center.The essential technology is pretty simple. We take the PC image itself, we virtualize it, and run that virtual desktop centrally on servers. So now from any device you can connect in and get your virtual desktop streamed to you. This increases the availability of the desktops, and provides the end users the freedom to connect to the desktop from any device at any time from anywhere. At the same time, for IT, it consolidates the management of the desktops. So they can manage a few of these “master” desktops, instead of managing every endpoint.Virtual desktops provide an easy way for IT to increase the availability and access, improve security, while decreasing downtime. Ultimately, all of this means better productivity and greater business agility. This sounds great, which is why there is a lot of interest in desktop virtualization.VDI is just one form of desktop virtualization and is what we will focus on in this training.There are two deployments of VDI that are commonly utilized, Personal Virtual Desktops and Virtual Desktop Pools. T: Personal Virtual Desktop gives the end user freedom to move.

The amount of concurrent users that a single Cisco router or server can support depends on the four key components:How many CPU cores it has and are they hyper-threaded;How much RAM is available;How many drives it has, their type (SAS, SATA or SSD), their speed, and how many disks it has; andHow much storage it has. In this example, the ISR G2 routers have been sized to support 25 Windows 7 desktops (20 pooled, 5 personal desktops) and have:Five hyper-threaded CPU Cores;48GB RAM;Two 300GB 15K SAS Drives using Raid 0; andRequires a minimum of 1.625MB of network bandwidth [ENTER] The VDI-in-a-Box GridThe real magic comes with the VDI-in-a-Box Grid. This is what enables growth without re-architecting; and High-Availability without a SAN. The Grid is just a collection of routers or servers connected over an IP network. The routers or servers work as a single entity, adjusting for different performance and capacities and handling all load balancing across the grid. [ENTER] High-AvailabilityVDI-in-a-Box uses the N+1 high-availability model. Add one additional router and the Grid load balances the 25 users in this example across both. [ENTER] In the event one router fails, there is capacity on the other for all 25 users. Unlike other VDI solutions, VDI-in-a-Box doesn’t need a SAN, Windows servers, SQL databases or a DBA to provide HA. It’s built into the software appliance, and all done with the local storage and that one extra router. ScalabilityNeed to grow the number of users you need to support. Add another router or blade, or you can add some Cisco UCS servers. [ENTER] The Grid allows you to mix the type of components that are running the VDI-in-a-Box virtual machine and automatically adjusts for their performance and capacities. The Cisco UCS C260 M2 servers in this example have been sized to support 100 Windows 7 desktops (80 pooled, 20 personal desktops) and have:Sixteen hyper-threaded CPU Cores;256GB RAM;Seven 250GB 15K SAS Drives using Raid 0; andRequires a minimum of 6.5MB of network bandwidth You don’t even need to take the Grid down to add servers as it a hot pluggable grid. The Grid automatically copies all images, data, templates and preferences to new server and brings it online. [ENTER] Software Updates and UpgradesUpgrades are just as easy [ENTER] as they need only to be performed on one server in the Grid. Here, we are adding Windows 7 to the VDI-in-a-Box virtual machine running on the first router [ENTER] and this change is automatically passed to all other router and servers in the Grid. So that’s what it looks like to IT. Now let’s look at what the user experiences. [ ENTER to go to the next slide)
Because the Grid acts as a single entity, the users never have to be concerned with which router or server they need to login into, what operating system they need or where their applications are. Once they login with their credentials, everything else is transparent to them – the Grid serves up a desktop on the least loaded router or server and presents them with a full Windows desktop.

Focusing on each component, lets’ start with the ISR G2.For UCS E-Series Servers, ISR G2 functions as the server blade enclosure. The advantage of this approach is that the ISR G2 is the most widely deployed branch office device and already has slots for various networking modules. Now you can re-use the same slots for x86 blade servers.The ISR G2 has a rich set of functionality. The features that are relevant when considering it in the context of a blade server chassis are the following:1,2,4 blade slot options depending on the ISR G2 model. 2911 and 2921 have 1, 2951 and 3925 have 2, and 3945 has 4The router provides comprehensive security measures to prevent un-authorized access, but also unlike stand-alone servers, blade servers reduce the physical attack surface by eliminating wires to tap into, ports to listen on, monitors to peek at.The 3900 ISRs have options for redundant power supplies to improve high availabilityMulti-Gigabit backplane switch allows direct access to the LAN either through EHWIC or SM EtherSwitch modules, without sending the traffic through the router CPU ISRs have typically 5-6 year service life, but have been designed to last much longer. The overall system MTBFs are in 250K-300K range compared to 100K-150K for a typical branch serverISR G2 with slots come in 2 or 3 RU form factorsUnlike any other device on the market ISR G2 can consolidate ALL branch office services into a single box. These include:Connectivity: LAN and WANMobility: Wireless LAN and WANApplication Performance: WAN optimizationSecurity: VPNs, Firewalls, IPS, AAACollaboration: voice gateways, video processing, call management, and voicemailApplication platforms: network integration for applications
You understand the benefits of VDI, so this presentation examines the top five VDI considerations from a company point of view and compares two approaches to implementing VDI: the traditional enterprise VDI architecture and VDI-in-a-Box with a shared-nothing architecture. Companies have come to realize that they can drastically cut operational costs, optimize use of computing resources and increase employee productivity by deploying virtualized desktop infrastructure (VDI). VDI can free end-users from the tethers of their desktop computers and enable them to access corporate desktops anytime from any device, including tablets and mobile phones. The result is a more agile, responsive and secure computing environment that scales quickly, creating real market advantages in today’s fast-paced business world. As enterprises adopt VDI and increase business agility while reducing support costs, other businesses want to do the same—but face tight resource and budget constraints. Many VDI solutions are designed for enterprises and are an extension to server virtualization, requiring the same type of datacenter setup, along with expert IT resources. While companies can amortize the costs for such a footprint, this approach requires a high upfront investment, and if the number of virtual desktops is low or phased in gradually, it can take a long time for a business to generate a return on investment (ROI). For both these reasons, traditional ways of delivering VDI simply don’t work for many companies.

The company assists clients in buying, selling, financing, leasing, managing and valuing assets, and provides strategic planning and research, portfolio analysis, site selection and space location and other advisory services. Cushman & Wakefield seeks to provide its professionals with the technological resources they need to add value at every step of the real estate process.The ChallengeCushman & Wakefield recognized the value of virtual desktop infrastructure (VDI) and wanted an efficient way to try out virtual desktops on a small scale. They weren’t sure whether VDI would work for them, so they were not ready to invest a lot of money in the VDI infrastructure. When the EMEA office needed a way to allow employees of a third-party contractor to access proprietary applications without exposing the firm to security risks, the perfect VDI proof of concept opportunity presented itself. They were not sure about their security policies, so they wanted two separate environments. They wanted something really small and consolidated. They wanted it quick, not very expensive and resilient.The Solution – VDI-in-a-Box, a quick, easy VDI solution for multiple business needs VDI-in-a-Box literally took only two days to do the proof of concept. It was so simple there was not very much of an effort, but it delivered a lot of value.Just as the IT team completed the virtual desktop implementation for the initial support contractor, Cushman & Wakefield undertook a project in Dubai that required a finance system to be deployed in a local office. However, corporate security protocols required finance systems to be deployed in the datacenter, not the local office. So, VDI-in-a-Box was an ideal solution for them. They created a VDI-in-a-Box template for them, deployed it for these users and exposed to their SSL VPN connection. Now when they log in they could come into the web browser, into the Citrix Receiver, and then just work normally, as if they were in the office.The virtual desktop “experiment” proved to be the solution to other branch office problems, as well. A client-server session in a Spanish office was continually crashing as they tried to access the same finance system . IT gave them the same VDI-in-a-Box solution, and they were very happy with the performance. Belgium had a similar problem with a client-server solution that just didn’t work. It was too slow. Now, Cushman & Wakefield’s offices in Dubai, Spain and Belgium are accessing the finance system virtually, with VDI-in-a-Box.

THE NOTES WILL BE REWRITTEN SO IT STAYS GENERIC AND THE PRESENTER KNOWS WHAT TO SAYThe Reject Shop, a VMware shop, spent months without much success evaluating various virtual desktop solutions for their Pop-up Stores – temporary seasonal stores. The system had to securely support iPads which they use for processing sales. Everything they evaluated was too overhead intensive and required too much management. A new Citrix sales rep and a new Citrix SE joined a new Partner in presenting VDI-in-a-Box – demo’d on iPads. The decision-maker, very knowledgeable with VMware, couldn’t believe how simple it was. They downloaded the trial and 6 days later placed a 60 license order with another 200 to follow. Quick and simple setup on-demand for their Pop-up Stores and simple management were key in their decision to deploy VDI-in-a-Box.Account SituationNeeded to support virtual desktop in their Pop-up Stores (temporary sites)Needed iPad support for order processingWanted a solution with minimal overhead and management requiredPrice sensitive to MSFT product licensingResult:1st meeting to purchase order in 6 daysSold 60 VDI-in-a-Box licenses and 2 serversAn additional 200 license order is planned for Q2Why VDI-in-a-Box?This very knowledgeable customer, running a large VMware shop, decided only VDI-in-a-Box provided the quick setup and minimal overhead they needed:Support for iPads standardQuick and simple setup on-demand (doesn’t require a WAN to support the stores)Self-contained (server(s), Wi-Fi router)The whole system could be run by existing IT staffOnly required MSFT VDA licenses
