1. Desktop Virtualization Exploring new technologies to simplify and stabilize desktop reliability and support

2. What is Desktop Virtualization? Simplistic Definition - Removing the client OS from the desktop hardware and moving it to a Hypervisor, from which it can be accessed remotely Different than session virtualization (Terminal Services) Sometimes called VDI – Virtual Desktop Infrastructure

3. Example of VDI Model

4. Desktop Client Model

5. VDI Model

6. Benefits of Desktop Virtualization for the IT Dept Decreased downtime when client and server hardware fails Easily manage and deploy new OS’s, updates, and applications Centralized management of desktops Ability to backup desktops and user profiles Enhanced security Scalability Potentially lower TCO, and better ROI Environmentally friendly Malware infections can be quickly wiped out by restoring the desktop to its original state

7. Benefits for the User Familiar personalized desktop experience. Each user has their own separate VM unaffected by changes or problems with other desktops in the cluster The desktop or application can be accessed via any LAN, WAN, or Public connection, using any desktop, laptop, thin client, or smart phone Faster server hardware provides superior desktop experience Faster access from desktops to servers and applications across datacenter switches The desktop VM and applications can be delivered to the client to be run locally and offline in the event of connection failure

11. So you wanna build a VDI environment?

12. VDI Companies & Products VMWare - View Citrix - XenDesktop Microsoft - Remote Desktop Services VDI Suites Quest Software - vWorkspace RedHat – Enterprise Virtualization Kaviza – Grid Architecture VDI Atlantis Computing - iLiO

13. VDI Protocol Common Features Support for split view up to 4 monitors with resolutions of 1920 x 1200 Provides lossless image transfer (needed for applications such as 3D Design, CAD, medical applications, etc). Supports all image content including 3D graphics, video, animation, etc. Support for High Definition Audio USB support for peripherals like web cams, printers, and scanners

14. Top 3 VDI Protocols

15. HyperVisor

16. Server Hardware 10 - 20 desktops per core depending on processor At least 512mb RAM per Desktop with at least 32mb reserved for video if running dual monitors High-speed shared storage for performance and data redundancy Multiple hosts for HA and DR High speed connection to backbone and WAN

17. Network Infrastructure Sufficient bandwidth at the datacenter and remote sites (varies greatly depending on the protocols used and amount of virtual desktops being accessed) Low Latency between the datacenter and remote site. Anything between 1 – 50ms is great 50 – 100 is good 100+ the experience begins to suffer

18. Client Hardware Thin clients Zero Clients Thin Clients with a local hard drive and OS for Type 1 or 2 client virtualization Desktop or Laptop PC’s with either Windows or Macintosh Mobile Devices (Smart phones, etc)

19. The Future…… Continued push to virtualize servers, desktops, and applications and move them to the cloud Businesses will switch from purchasing high-end PC’s to more thin clients or lower end PC’s Home users will start moving their desktops to the cloud According to a Gartner report “The worldwide hosted virtual desktop (HVD) market will accelerate through 2013 to reach 49 million units, up from more than 500,000 units in 2009, according to Gartner Inc. Worldwide HVD revenue will grow from about $1.3 billion to $1.5 billion in 2009, which is less than 1 percent of the worldwide professional PC market, to $65.7 billion in 2013, which will be equal to more than 40 percent of the worldwide professional PC market.”
