Will Remote Desktop Session Host and Remote Desktop Virtualization Host kill Rich Clients?Did online banking and credit cards replace cash and wallets?Did public transport services replace individually owned vehicles?There’s a simple rule: Virtual Desktops are useful for all enterprises, but not for all users!
Well, it turns out that of all hypervisors we have tested, Hyper-V R2 does best for Windows 7 VM density for this benchmark. Congratulations to the Hyper-V team for a fine job on this workload. XenServer 5.5 peaks at about 10% less than Hyper-V, and all other hypervisors perform less well than XenServer. The
Now, the two features, as it turns out, are very exciting in the context of you being a VDI user, because really on the cost side one of the challenges you have in VDI is when you have desktops, you have lots of desktops. And if each desktop requires a 2 gigabyte, for example, amount of memory, which is a good amount of memory to run Windows 7, then your server memory capacity is going to be stretched at a relatively short timeframe. So, given that in the desktop environment, not everybody is using their desktops at the same level at the same time, are there optimizations that we can do to fix that, and I think there are. So, the notion here is that while you should always size your systems relative to what your peak capacity is, and this Dynamic Memory doesn't help with peak capacity, you can definitely improve your capacity over time, given that some people are using their desktops, some people are being very intensive on what they're doing on the desktops, some people are being very light on what they're doing on the desktops, and some people frankly have their VDI desktops open but are in meetings and are not using it at all. So, depending on what the workload is on a specific desktop, the memory requirement changes. So, this Dynamic Memory feature really takes advantage of that fact, and dynamically sizes the memory of the virtual machine based on the requirements of that virtual machine.So, you set the little radio box here to dynamic, with some parameters around it, and Hyper-V begins controlling the memory management of Windows. So, when I go to a meeting and I'm not running anything, then that virtual machine will give back its memory back to the pool, and another virtual machine can use that memory. When I'm back and I'm loading multiple instances of Excel and doing lots of complex calculations, then Hyper-V will go ahead and give me back memory from the pool. So, what this feature really does is improve the overall capacity by recognizing that various workloads are sometimes strongly used, sometimes not used at all, and in aggregate the system can do a better job of memory management through the Hyper-V than within each one of the virtual machines. So, Dynamic Memory is an exciting feature coming in Windows Server 2008 R2 service pack 1. A second key feature here is really RemoteFX. Now, RemoteFX is really focused on the fact that the VDI user experience is a lower user experience than the PC user experience. There are some physics challenges, of course, associated with this, wide area networks in particular, and actually our partner Citrix is probably the leader in the market in terms of providing a wide area network experience. However, what we have done is really focused on a technology we call RemoteFX that improves over LAN networks the user experience, and in particular some of the key areas historically with a VDI experience that have been a challenge have included things like 3D graphics. So, if you are thinking about using a CAD/CAM or if you're thinking about using any 3D software in your VDI environment, it's historically been a challenge. And the RemoteFX technology, which comes from the acquisition of Calista that we made in 2008, really addresses that. RemoteFX technology builds on the notion that you install server-side graphics hardware, and by putting a server-side graphics card in, the computing of the graphics experience occurs on the server, and you can have a full fidelity graphics rich desktop piped to any type of device: thin client, PC, the whole lot. So, what you can see here on this small screenshot is full Aero glass. You get things like peek and thumbnails and the whole lot. And, in addition to that, your OpenGL, your direct 3D applications just work. So, the fidelity of the desktop experience is significantly higher for LAN environments using RemoteFX. And RemoteFX, in fact, is a very open protocol, and we have recently announced that our partner, Citrix, will be building support for RemoteFX into their HDX technologies. So, it's a very open environment, and we encourage that. So, once again, I just want to go back and really reinforce that Windows 7 service pack 1, as opposed to Windows Server 2008 R2 service pack 1, does not have any new features in it, okay? So, we are not adding features to Windows 7 service pack 1. It's all about updates. There's really no need to wait for it. It's not a big deal here, given that in this day and age updates are available to you through WSUS or through Windows Update, should you choose to use it, for the issues that are most important. So, Windows 7 service pack 1 is really not a big deal in terms of features; there aren't any. Windows Server 2008 R2 service pack 1, if you're not doing VDI, is also not a big deal in terms of features. If you are doing VDI, there's the great new features of RemoteFX and Dynamic Memory that really support my statements earlier, that Microsoft is absolutely embracing VDI, and we certainly want to be the technology with Citrix in many cases to enable that. So, to that exact point, certainly when you're comparing VMware versus Microsoft in the VDI space, then I would recommend you look at the combination of XenDesktop on top of Hyper-V. Remote FX: With Microsoft RemoteFX, users will be able to work remotely in a Windows Aero desktop environment, watch full-motion video, enjoy Silverlight animations, and run 3D applications within a Hyper-V VM – all with the fidelity of a local-like performance.
Moving on , Microsoft and Citrix has a strong partnership in VDI offering.Some of the key components of the Microsoft VDI offering are:First, on the Virtualization Platform. Microsoft has Hyper V R2. Hyper V R2 is a Hypervisor based virtualization system which allow you to virtualize Remote Desktop Services and Client operating system on a single physical machine. In R2, you can introduce Failover Cluster and Live Migration. Live migration allow you to migrate virtual machine from one node to another node without any interruption. User will not experience interruption when accessing to remote desktop.2. Next, on Desktop and Session Delivery. Last year November, Microsoft has launched Windows Server 2008 R2 which allow you to VDI with Remote Desktop Services. Desktop and application can make available to user by using RDS.3. Then on Application Delivery, Microsoft has Application Virtualization (in short form- called App-V) allow you to virtualize application and stream the application to the user desktop. For example, you have Microsoft Office 2010 and Office 2003. By using App-V, both application can run without any conflict. Meanwhile on R2, you can use RemoteApp to host application on the server and make it available to user. This is similar as terminal service.4. Moving on, on User profiles and data. Microsoft has Roaming profile feature in. Roaming profile is one of the features which allow you to have similar setting and desktop wallpaper when you access to desktop virtual machine. Folder redirection refer to automatic rerouting standard folder such as My Document, My Picture and Start Menu to a shared storage. By using folder redirection, you can introduce centralize data and backup.Lastly on Management side, Microsoft has System Center Management Suite.1. Systems Center Virtual Machine Manager 2008:VMM allow you manage physical and virtual machine infrastructure. You can use VMM to perform commissioning and decommissioning of virtual machine as well as to perform P2V (Physical to Virtual Machine conversion) . By using P2V, you can convert your existing physical desktop to virtual machine and store into data center.2. SCCM allow you to perform software update, software distribution, operating system deployment, asset management, hardware and software inventory.3. SCOM provide an end to end solution for monitoring. You can integrate with VMM to enable reporting and enable one of the feature called enable PRO TIP. PRO TIPS allow the system to react. Example: If physical host not enough RAM, PRO TIPS can move the host which has available system resources.Lastly, MDOP is available for Software Assurance and APP-V is part of MDOP.On Citrix technology, Danny will talk more about it later.---------------not important-----------------------------------Desktop delivery through Citrix Xen Desktop:Citrix XenDesktop™ offers a next-generation, user-centric desktop virtualization solution that provides a complete system for desktop delivery. XenDesktop dynamically assembles virtual desktops on-demand, providing users a new, yet personalized, desktop each time they log on – ensuring that performance never degrades. In addition, XenDesktop’s high-speed delivery protocol provides unparalleled responsiveness over any network which helps in desktop optimization. Hence, in the WS08 R2 timeframe, we will have two options for implementing VDI:For large, complex enterprise deployments, the joint Microsoft and Citrix solution will continue to offer a superior set of features.For small scale departmental implementations, the Microsoft-only stack will provide the best balance of features and price.Organizations that are considering VDI today, are encouraged to deploy the current Microsoft-Citrix offering, as this will enable them to lay a foundation to grow their VDI infrastructure in the future.
NEW Desktop Studio lets IT admins quickly build, test and update desktop images in one place, once for all users. With XenDesktop 5, it takes just 10 minutes to install, 10 clicks to configure, and 10 seconds to add new desktop users. It’s recommended that you show a demo or demo video of Desktop Studio.
For the helpdesk, the NEW Desktop Director provides a single console where they can monitor, troubleshoot and fix virtual desktops for 1,000 users as easily as for one.
The way we use computing to work has changed pretty dramaticallyWe started with commandsWe moved to a graphical look and using appsThen the desktop metaphor came and we started focusing on documentsWith the web its about contentThe future is about doing whatever, whenever, wherever
