- Time: 3-4 minKey Message: This slide presents virtualization as a key solution for solving the business challengesWhy should the audience care? The audience should understand the value that virtualization can add to their business and how it helps to convert IT from a cost center to a business enabler Additional notes:In traditional physical computing, every piece of the computing platform—for example the processor, storage, memory, network, and application—is directly dependent on the others. Virtualization removes this dependency. Separating these pieces enables greater flexibility in your IT infrastructure. For example:Consolidating IT infrastructure Fully automating IT tasks that lead to lower TCOAdhering to business policies with streamlined daily IT operationsIncreasing the flexibility of provisioning IT services to end users Hardware and software can be used in more diverse ways Systems can be made more secure by isolating problem areas IT will also be better prepared to handle common—but difficult—problems: Accelerate application deployments Ensure the availability of systems, applications, and data Take the hassle out of rebuilding servers and desktops for testing and development Reduce security risks Reduce costs Improve the agility of the organization’s entire environmentVirtualization technologies have the potential to transform your infrastructure.
- Time: 3-4 minKey Message: This slide presents Microsoft virtualization portfolios that includes Presentation Virtualization, Server Virtualization, Application Virtualization, Desktop virtualization and User State VirtualizationWhy should the audience care? The audience should understand the capability of Microsoft to provide complete virtualization solution for their organization right from the user state to the datacenterAdditional notes:Microsoft provides greatly expanded virtualization capabilities that enable IT organizations to significantly reduce operating costs, drive up server utilization, and achieve better return on investment (ROI) through full featured virtualization solutions. There are four types of virtualization technologies available from Microsoft, including server, desktop, presentation (using Terminal Server), and application (using Microsoft Application Virtualization). In this slide, we explore the four types of virtualization technologies. ServerVirtualization: Server-based technologies that enable server virtualization include Microsoft Virtual Server 2005 R2, Windows Server 2008 with Hyper-V and Windows Server 2008 R2. Windows Server virtualization provides a highly reliable, scalable, and flexible virtualization platform, enabling even very demanding server workloads to run in virtual machines (VMs) that take advantage of centralized management, powerful clustering, and enhanced security features. Windows Server virtualization enables "hot-add" of virtual resources to running VMs without downtime. It allows VM partitioning and isolation, reduces the server's attack surface using a virtual machine manager (VMM), and uses Page Sharing to optimize memory. Dynamic VMs in WSV can migrate from one server to another without downtime with Live Migration, run 64-bit or 32-bit operating systems side-by-side, use a variety of operating systems, and use advanced networking features, including VLAN, NAT, and Quarantine. DesktopVirtualization: Virtualization at the desktop level is provided by several different technologies, depending on your business requirements. For local desktop virtualization, IT Professionals can use Virtual PC 2007 to run multiple operating systems at the same time on the same physical computer, and switch between them as easily as switching applications—instantly, with a mouse click. Or they can deploy Microsoft Enterprise Desktop Virtualization (MED-V) which provides centralized management and deployment of locally executing Virtual PC images. Server-hosted desktop virtualization with Microsoft Virtual Desktop Infrastructure and VECD (Windows Vista Enterprise Centralized Desktop) enables you to deploy Windows Vista centrally in VMs that run in the data center and which users connect to remotely over the network.User State Virtualization: User state virtualization is a critical component of any desktop virtualization strategy, because it separates the user data and settings from the PC and enables IT to store them centrally (i.e., in the datacenter) while also making them accessible on any PC. Session Virtualization (with Remote Desktop Services): Remote Desktop Services in Windows Server 2008 R2 enables presentation virtualization that enables access, from almost any computing device, to a server running Windows-based programs or the full Windows desktop. Users can connect to a Remote Desktop Session Host (fkaterminal server or to a Remote Desktop Virtualization Host to access a desktop or programs, and to use network resources on that server. With Remote Desktop Services, applications are physically installed and are executing on back-end servers, not the desktop. Application Virtualization (using Microsoft App-V): Using App-V orMicrosoft Application Virualization (formerly known as Softgrid) provides organizations with application virtualization solutions that reduce the TCO of desktop deployments. Application virtualization can be layered on top of other virtualization technologies—network, storage, computer—to create a fully virtual IT environment where all computing resources can be dynamically allocated in real-time based on real-time needs. This is called the SystemGuard™ virtual application environment. SystemGuard enables each application to bring its own set of configurations and run within a protective run-time "sandbox" on the client, so there is no dependency or effect on the configuration of the machine running them. However, because applications execute locally, they run with full performance, functionality, and access to local services—including cut and paste, OLE, printing, network drives, and attached devices. Management: All assets, both virtual and physical, are managed from a single platform and a ‘single pane of glass’. The Microsoft System Center family of familiar, industry-standard management tools can be used to manage the virtualized environment. System Center Virtual Machine Manager and System Center Operations Manager work together to give virtual machines enhanced security features, business continuity, and disaster recovery features. VMs and servers appear along with physical devices in common, familiar management tools.

- 1 dkTime: 3-4 minKey Message: This slide introducesMicrosoft session virtualization offering through Remote Desktop Services in Windows Server 2008 R2Why should the audience care? The audience can get familiar with the session virtualization offering and its enabling product from Microsoft Additional notes:Session virtualization separates where an application is used from where it is run, enabling organizations to consolidate applications and data in the data center while providing broad access to local and remote users. Remote Desktop Services accelerates and extends the deployment of desktops and applications to a wide array of client devices, helping make your organization more agile and responsive. These new services provide full-featured presentation virtualization solutions that can result in:Enhance user experienceIncrease IT controlIncrease business acuityImprove IT security
- Introducing the new name in R2Microsoft has been investing in many new remote desktop & VDIareas with Windows Server 2008 R2. These changes such adding support for VDI scenarios, integrating Terminal Services and VDI management infrastructure, the investments we are making, providing new and improved user experience extend and broaden the use of this feature set beyond traditional terminal scenarios; as such we are pleased to announce Terminal Services is being renamed to Remote Desktop Services to reflect the breadth of scenarios we now provide.
- 1 dkAudio and video playback redirection. Audio and video playback redirection allows users to redirect the audio and video output of a local computer to an RD Session Host session.Audio recording redirection. Audio recording redirection allows users to redirect the output of an audio recording device, such as a microphone, from the local computer to an RD Session Host session.Desktop composition. Desktop composition provides users with the user interface elements of the Windows® Aero® desktop experience within their RD Session Host session.The following steps set up the server to support Aero Glass remoting:1) Add the Desktop Experience feature from the Server Manager.2) Set the Themes service to autostart, and start the Themes service.3) Enable the “Allow desktop composition for remote desktop sessions” policy from gpedit.The policy path is “ComputerConfiguration\\AdministrativeTemplates\\WindowsComponents\\Remote Desktop Services\\Remote Desktop Session Host\\Remote Session Environment”4) Enable 32bpp:In Server Manager, go to “RD Session Host Configuration” under “Remote Desktop Services” role, right-click on the connection to bring up “RDP-Tcp Properties”:Uncheck “Limit Maximum Color Depth” from “Remote Desktop Session Host Configuration.”Fair Share CPU SchedulingFair Share CPU Scheduling is a new feature included with Remote Desktop Services in Windows Server 2008 R2. Fair Share CPU Scheduling dynamically distributes processor time across sessions based on the number of active sessions and load on those sessions by using the kernel-level scheduling mechanism included with Windows Server 2008 R2. On a remote desktop server, one user will not affect the performance of another user's session, even if the remote desktop server is under a high load.Fair Share CPU Scheduling is enabled by default. You can disable this feature by configuring the following registry entry to 0: HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft\\Windows\\SessionManager\\DFSS\\EnableDFSS.Why is this change important? Prior to Windows Server 2008 R2, the Windows scheduler provided a fair scheduling policy by distributing the processor time evenly across all threads at a given priority level. Priority could be adjusted by using management software to give one thread preference over another. In an environment with multiple users, this scheduling policy provided a good way to throttle any one user from completely monopolizing the CPU, but was unable to evenly distribute the processor time in the presence of dynamic loads.
- Roaming user profile cache managementA new Group Policy setting is available for Remote Desktop Services in Windows Server 2008 R2 that limits the size of the overall profile cache. If the size of the profile cache exceeds the configured size, Remote Desktop Services deletes the least recently used profiles until the overall cache goes below the quota.
- Remote Desktop IP VirtualizationRemote Desktop IP Virtualization allows IP addresses to be assigned to remote desktop connections on a per session or per program basis. Remote Desktop IP Virtualization is configured on the RD IP Virtualization tab of the Remote Desktop Server Configuration tool. If you assign IP addresses for multiple programs, they will share a session IP address. If you have more than one network adapter on the computer, you must also choose one network adapter for Remote Desktop IP Virtualization. Why is this change important? Some programs require that each instance of the application be assigned a unique IP address. Prior to Windows Server 2008 R2, every session on a remote desktop server was assigned the same IP address. With Windows Server 2008 R2, you specify a network ID that Remote Desktop IP Virtualization uses to assign IP addresses on a per session or per program basis.
- Time: 3-4 minKey Message: This slide shows the key benefits of Terminal Services. This purpose of this slide is to help the presenter introduce the key benefits of TS first and then introduce what is new and improved in R2.Why should the audience care? Audience can get familiar with what Microsoft already provide through Terminal Services.Additional notes:Microsoft Terminal Services in Windows Server 2008 provides presentation virtualization solutions and has undergone significant enhancements in Windows Server 2008 R2. To reflect the continued focus on enhancing the remote desktop experience, in Windows Server 2008 R2 Microsoft has renamed Terminal Services to Remote Desktop Services . The change in RDS, however, goes far beyond just a name as it now supports both presentation and desktop virtualization technologies as part of the platformis of R2 improvements.Terminal Services provides the following key benefitsSimplified Remote Application Delivery Terminal Services RemoteApp™ applications appear no different than local applications. They work seamlessly with the task bar and new Windows Vista® features like 3-D flip.

- 1-2Time: 3-4 minKey Message: This slide provides an overview of what is new and improved in RDSWhy should the audience care? Audience can get an overview of the key new features and enhancements over Terminal ServicesAdditional notes:Completing the Remote Desktop Services toolset addressing customer needs. Remote Desktops Services in Windows Server 2008 R2 improves capabilities forthe existing scenarios delivered previously in Terminal Services, and in addition RDS adds exciting new VDI scenarios.Remote Desktop Services in Windows Server 2008 R2 includes the following improvements over Windows Server 2008 :Extending Remote Desktop Services to enable a Virtual Desktop Infrastructure (VDI). The in-box Remote Desktop Services capability is targeted at low-complexity deployments and as a platform for partner solutions, which can extend scalability and manageability to address the needs of more demanding enterprise deployments. Combined with Microsoft Hyper-V Server, System Center Virtual Machine Manager, App-V within MDOP, and VECD licensing, Microsoft provides a complete end to end VDI solution.Providing simplified access to Remote Desktops and Applications. The new RemoteApp & Desktop Connections feature provides access to a set of resources, such as RemoteApp programs and Remote Desktops. For Windows 7 users, these remote resources are made available, and are continually updated, via the new RemoteApp & Desktop Connection control panel. The new RemoteApp & Desktop Web Access provides the ability to connect to resources from Vista & XP in addition to Windows 7. RD Gateway securely provides access to these remote resources from outside the corporate network without the need for opening additional ports or the use of a VPN. Improving User Experience through new Remote Desktop Protocol capabilities. These new capabilities, enabled with Windows Server 2008 R2 in combination with Windows7 Enterprise Edition and Ultimate Edition, improve significantly the experience of remote users, making it more similar to the experience enjoyed by users accessing local computing resources.
- Time: 3-4 minKey Message: This slide provides an overview of how RDS provides a flexible virtualization platform for remote desktop and application deployments Why should the audience care? Audience can understand the capability of RDS to support various desktop deployment optionsAdditional notes:Windows Server 2008 R2 Remote Desktop Services embraces Virtual Desktop Infrastructure (VDI) scenarios,delivering a complete business desktop to employees’ remote PC’s and other access devices. The new Remote Desktop Connection Broker, which extends the Session Broker capabilities already found in Windows Server 2008, makes it easier for administrators to deliver remote resources (desktop, applications) to end user devices. The Remote Desktop Connection Broker supports four key deployment scenarios :Session-based Remote DesktopsSession-based Remote Applications (RemoteApp)VM-based, Personal (permanent) Virtual DesktopsVM-based, Pooled (non-permanent) Virtual DesktopsIf your organization includes structured task workers, such as call center and retail branch employees, you can provide access to a session-based desktop or session-based applications installed on a Remote Desktop Session Host. This type of deployment allows access to standard applications in a cost-effective manner and enables users to access LOB applications even from their legacy systems.In the case of VM-based desktops, the out-of-the-box solution supports the storage of virtual client images on a Hyper-V host server. Hyper-V is the foundation of Microsoft server and desktop virtualization solutions and is installed as a role on Windows Server 2008 and Windows Server 2008 R2. RDS supports both personal and pooled virtual desktops.
- 1-2Cont…Personal Virtual DesktopThe Personal Virtual Desktop uses a dedicated virtual machine that is assigned to a particular user. All user data (such as My Documents) and profile information (personalization) is retained on an image specific to the virtual machine, so the experience is similar to a physical desktop client. This deployment is suitable for knowledge workers (for example software developers or testers) who require administrator rights to have full control over their desktop and who need to be able to deploy their own applications. A personal virtual desktop also allows for full customization and personalization of the virtual desktop, similar to a physical desktop. Pooled Virtual DesktopAnother way of deploying virtual machine-based desktops is through pooled virtual machines that are identically configured and hosted on one or more Hyper-V servers. Pooled Virtual Desktops are best suited for task workers or even some office workers who need to work on some standard applications and do not require administrator rights for desktop configuration, or a lot of customization. In this configuration, when a user’s session ends, their data is not stored on the virtual machine. A typical configuration uses folder redirection to save their data to another server so it is available when they next log on, but no configuration data is saved between sessions. The Pooled Virtual Desktop is a more efficient use of virtual machine resources—a given set of virtual machines can support a larger number of users than the Personal Virtual Desktop .

- Implement "Loopback Processing" on GPOs to control settings for users that are not in the same OU as the terminal server computer objects – This is most important when you have users from different OUs accessing terminal servers that are in another OU. When using this configuration, because user accounts log on to the servers after the servers are booted, there may be inconsistencies between the terminal server-linked GPOs and the GPOs for the user accounts. In this case, you can use the GPO loopback feature to apply Group Policy Objects that depend only on which computer the user logs on to.If the protection of the traffic between the clients and the terminal server is important, use IPSec to add an extra layer or security and encryption to the traffic
- Limit the idle session and disconnected session time – Idle sessions should not be left open for ever, and they should be automatically terminated after 15 or 30 minutes. Disconnected sessions, on the other hand, are harder to control because of the possibility that a user's connection has terminated due to network issues, and killing that session will result in lost un-saved data on the user's session. I use 3 hours for application or desktop sharing, and 24 hours for remote administration scenarios.
- This setting determines whether bitmaps are cached on the local computer. Bitmap caching can improve the performance of your remote session by storing frequently used images on the local computer.
- With regards to the RemoteFX RDSH scenario the only hardware requirement is that the CPU has SSE2 instructions. The server will need to be running Windows Server 2008 R2 SP1 in order to enable the RDSH role. Hyper-V/Physical GPUs are not required as we do not virtualize a GPU. You *can* virtualize the RDSH role and enable RemoteFX compression and that *will* work. You get the same rich media full fidelity video/user experience but you do not get 3D acceleration since there is no physical GPU(s) being virtualized and exposed to the session, which also means no Aero.
- SLAT is a feature of the CPU, and .is also known as Extended Page Tables (EPT) by Intel and Nested Page Tables (NPT) by AMD. You can use Wikipedia to look up Intel Nehalem and AMD NPT: http://en.wikipedia.org/wiki/Intel_Nehalemhttp://en.wikipedia.org/wiki/AMD-V_Nested_Paginghttp://en.wikipedia.org/wiki/Extended_Page_TableSLAT-enabled processor The processor in the RemoteFX server must support Second-Level Address Translation (SLAT). In virtualization scenarios, hardware-based SLAT support improves performance. On Intel processors, this is called Extended Page Tables (EPT), and on AMD processors, it is called Nested Page Tables (NPT).Integer ve FPU ( Floating Point Unit ) Nedir ?
