virtual techdays INDIA │ august 2010 User State Virtualization User State Virtualization Users can view their unique settings and data from any connected PC. Users can access their data and folders from any connected PC. Users can see files on their PC without a network connection.

 OS installed on device, plus managed “guest OS” running under VPC  Applications installed on device and/or guest virtual machine  Allows abstraction from application-compatibility issues  Allows multiple user profiles on single client device  “Deploy a corporate PC to any endpoint, and run it seamlessly” virtual techdays INDIA │ august 2010 Client Virtualization: MED-V  Deploy virtual Windows XP images and customize per user  Provision and define applications and websites to users  Control usage permissions and Virtual PC settings  Maintain and Support endpoints through monitoring and troubleshooting

virtual techdays INDIA │ august 2010 MED-V: How it works Software Distribution

 OS installed locally on the client device  Applications delivered virtually, execute without being installed  Data stored on network, with folder redirection/replication  Uses device-specific physical resources virtual techdays INDIA │ august 2010 Application Virtualization: App-V  Readily accessible applications  Accelerate Windows deployment  Accelerate application recovery  Reduced application conflicts  Minimize app-to-app compatibility testing  Leverage existing PC Management investments

virtual techdays INDIA │ august 2010 App-V: How it works App-V client reads on launch, runs app local or via TS. App-V Sequencer Sequenced app and place on Content share. App-V Management Server (content) App-V Management Console App-V Terminal Server Desktop PC Virtual App is loaded into cache and icons and files are available to user. Virtual App is delivered to the client (RTSP/Http/ MSI/ESD). Standalone Mode (MSI) Use App-V Mgmt Console to import package from Content share, create application, and assign to AD Security Group. Package is available for Streaming, 3 rd Party ESD, or Standalone distribution. Use App-V Mgmt Console to import package from Content share, create application, and assign to AD Security Group. Package is available for Streaming, 3 rd Party ESD, or Standalone distribution. Streaming Server (RTSP) IIS Server (optional) (HTTP)

virtual techdays INDIA │ august 2010 MED-V vs App-V What it does Creates a package of a single application Eliminates software install What it is good for Resolve conflicts between applications Simplify application delivery and testing What it does Creates a package with a full OS What it is good for Resolve incompatibility between applications and a new OS Run two environments on a single PC (e.g. corporate and personal) Hardware Data, User settings Applications OS

 The client image is a virtual machine running in the datacenter  Client image is fully controlled/managed within datacenter  Allows abstraction from physical details of client device  Leverages datacenter resources (scale and elasticity) virtual techdays INDIA │ august 2010 VDI

virtual techdays INDIA │ august 2010 Selecting the Right Desktop Virtualization Strategy

virtual techdays INDIA │ august 2010 The Desktop Experience.. NEW PC After 6 Months Feels new A bit slow, but ok Stability & Application Problems Stability & Application Problems A bad user experience A bad user experience New PC After 6 Months After 2 Years After 4 Years Desktop Performance Configuration Control After 2 Years After 4+ Years High Control Great Performance Little Control Good Performance Lost Control Constant Troubles No Control Terrible Performance

What used to be a clear future… The roadmap to get there is just not so clear or simple anymore…

 Each of these solutions:  Has strengths and weaknesses  Depends (to varying degrees) on the datacenter  Depends (to varying degrees) on application architecture  Depends (increasingly) on management tools/processes  May only be appropriate for specific sub-segments of the users virtual techdays INDIA │ august 2010 Which one is right for me? MED-V App-V  But you don’t have to pick just one!  Multiple solutions can be combined to create flexible, targeted solutions  Workspace attributes can be dynamically composed  End-to-end management allows diversity without chaos  Your Desktops may benefit from ALL of these capabilities.

 VM Disk  Utilize Fixed Disks where possible  Reduces VM Disk fragmentation (mainly for non-SAN)  Cant be used in differencing disk scenarios  SCSI vs IDE doesn’t matter  VM Memory  Make sure there is sufficient RAM allocated to the VM  Increased Disk IO Pagefile growth from disk fragmentation (insufficient memory)  Increased fragmentation requires memory management  Lack of memory grows the pagefile  Growing pagefile requires more memory…and then creates more Disk IO virtual techdays INDIA │ august 2010 VDI Recommendations

virtual techdays INDIA │ august 2010 Windows Server 2008 R2 SP1 enhancements Dynamic Memory allows the allocation of a range of memory (min and max) to individual VMs, enabling the system to dynamically adjust the VM’s memory usage based on demand. This provides more consistency in system performance enabling better manageability for administrators Dynamic Memory RemoteFX Microsoft RemoteFX leverages the power of virtualized graphics resources and advanced codecs to recreate the fidelity of hardware- assisted graphics acceleration, including support for 3D content and Windows Aero, on a remote user’s device. This allows for a local- like, remote experience.
