Source : Microsoft Technet

Go beyond doing more with less and reducing your carbon footprint; virtualization enables a more agile, responsive infrastructure and lays the foundation for cloud services.

By Mitch Irsfeld

With IT departments wedged between limited budget growth in 2011 and the expectations for new services–especially cloud computing–getting in the virtualization game has become a virtual no-brainer. The reason: Running enterprise workloads on virtual machines not only positions your existing IT infrastructure for cloud services, it delivers substantial savings over physical servers and enables a more agile, scalable and resilient server environment…

SCVMM for VDI deplyoments: tuning

February 4, 2011 Leave a comment

SCVMM as a platform

While most people are aware of SCVMM (System Center Virtual Machine Manager) being used for managing virtualized datacenters, it’s probably less well known that  a number of partners have built products using SCVMM as a platform by using the powershell based API.  Products that use SCVMM as a platform include Citrix XenDesktop, Quest vWorkspace and Visual Studio Lab Management (this is not an exhaustive list by any means).  Two of those products (XenDesktop and Quest workspace) are VDI (Virtual Desktop Infrastructure) management products that can be used to manage VDI desktop VMs.

VDI

VDI management has different usage patterns compared to server virtualization management. For example, VDI VMs are powered on during the morning when the users need to log on to their desktops and they get powered off in the evening after users log off (all this is controllable via policy). So it’s fairly common to power on large number of VMs in a short period of time which causes a spike in load on VMM to handle large number of parallel jobs. These kind of spikes in load can cause the system to become overloaded. While we continue to make improvements in future versions of SCVMM to handle such scenarios, this post is about best practices for configuring SCVMM 2008 R2 for managing VDI environments. The size of the environment is around 1000 desktop VMs, if you have larger environments, you’ll probably need to use multiple instances of SCVMM

December 6, 2010 Leave a comment

As many are requesting the links to download the Microsoft Hyper-V Cloud Deployment guides.

Building Private Clouds With Hyper-V Cloud and the Windows Server Platform

Windows Server 2008 R2, Microsoft’s server platform, already delivers comprehensive virtualization and management capabilities through Windows Server 2008 R2 Hyper-V. These technologies, along with Microsoft System Center, provide the components organizations need to implement private clouds. With the new Hyper-V Cloud Fast Track program, Microsoft and its partners will deliver a broad choice of predefined, validated configurations for private cloud deployments, comprising compute, storage, networking resources, virtualization and management software. These programs and offerings help reduce the risk and increase the speed of private cloud deployments.

Virtualisation planning process : memory configuration maximums.

October 21, 2010 Leave a comment

Today’s  challenge for a virtualization admins it’s to provision memory requirements within the guest for unique workloads,  paying attention to the host environment.

Although today, memory is relatively cheap, it may not be the case in the future and we also need to take in consideration the host maximums, as this will impact what OS would be available for a guest virtual machine as well as the aggregated impact on the host. It is notorios that system/applications that are replacing older servers running W2K/W2K3 to now require more resources(RAM, CPU, Disk, Network )  than the previous systems/apps.

It is important to pay special attention to the memory limits, requirements and aggregate memory capacity with insight to future needs.

Limits on memory and address space vary by platform, operating system, and by whether the IMAGE_FILE_LARGE_ADDRESS_AWARE value of the LOADED_IMAGE structure and 4-gigabyte tuning (4GT) are in use. IMAGE_FILE_LARGE_ADDRESS_AWARE is set or cleared by using the /LARGEADDRESSAWARE linker option.

Limits on physical memory for 32-bit platforms also depend on the Physical Address Extension (PAE), which allows 32-bit Windows systems to use more than 4 GB of physical memory.

Memory and Address Space Limits

The following table specifies the limits on memory and address space for supported releases of Windows. Unless otherwise noted, the limits in this table apply to all supported releases.

Memory type Limit in 32-bit Windows Limit in 64-bit Windows
User-mode virtual address space for each 32-bit process 2 GBUp to 3 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE and 4GT 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared (default)4 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE set
User-mode virtual address space for each 64-bit process Not applicable With IMAGE_FILE_LARGE_ADDRESS_AWARE set (default):x64:  8 TBIntel IPF:  7 TB2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared

Paged pool Limited by available kernel-mode virtual address space or the PagedPoolLimit registry key value.Windows Vista:  Limited only by kernel mode virtual address space. Starting with Windows Vista with Service Pack 1 (SP1), the paged pool can also be limited by the PagedPoolLimit registry key value.Windows Home Server and Windows Server 2003:  530 MBWindows XP:  490 MBWindows 2000:  350 MB 128 GBWindows Server 2003 and Windows XP:  Up to 128 GB depending on configuration and RAM.Windows 2000:  Not applicable
Nonpaged pool Limited by available kernel-mode virtual address space, the NonPagedPoolLimit registry key value, or physical memory.Windows Vista:  Limited only by kernel mode virtual address space and physical memory. Starting with Windows Vista with SP1, the nonpaged pool can also be limited by the NonPagedPoolLimit registry key value.Windows Home Server, Windows Server 2003, and Windows XP/2000:  256 MB, or 128 MB with 4GT. 75% of RAM up to a maximum of 128 GBWindows Vista:  40% of RAM up to a maximum of 128 GB.Windows Server 2003 and Windows XP:  Up to 128 GB depending on configuration and RAM.Windows 2000:  Not applicable

Short list of Microsoft Desktop Virtualisation solutions

October 13, 2010 1 comment

And how you can use them in your organization:

VDI: Enables users to access their personalized Windows desktops hosted on servers. For many organizations, virtualizing desktops within the datacenter is seen as an excellent means to provide a centrally-managed Windows desktop to connected users. http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=8d454921-72d6-45b4-b6ba-ac1c26d337bd

Session Virtualization: Makes it possible for you to run an application or an entire desktop in one location, but have it be controlled in another. Session virtualization allows you to install and manage session-based desktops and applications, or virtual-machine based desktops on centralized servers in the datacenter; deliver images to users, and send keystrokes and mouse movements from user client machines, in turn, back to the server. From a user perspective, applications are integrated seamlessly—looking, feeling, and behaving like local applications. http://technet.microsoft.com/library/cc742806.aspx

 MED-V: Provides you with the ability to deploy and manage virtual Windows desktops to help enterprises upgrade to the latest version of Windows, without having to worry about application compatibility. MED-V provides organizations the ability to run two operating systems on one device, adding virtual image delivery, policy-based provisioning, and centralized management. http://technet.microsoft.com/library/ff433588.aspx

App-V: Helps you make business applications available to end users on any authorized PC. App-V decouples applications from the OS and helps to eliminate application-to-application incompatibility, as applications are no longer installed on the local client machine. In addition, application streaming expedites the application delivery process so that your IT department no longer needs to install applications locally on every machine. http://technet.microsoft.com/library/ee958103.aspx

RemoteApp: Enables programs that are accessed remotely through Terminal Services to appear as if they are running on the end user’s local computer. Users can run RemoteApp programs side by side with their local programs. A user can minimize, maximize, and resize the program window, and can easily start multiple programs at the same time. If a user is running more than one RemoteApp program on the same terminal server, the RemoteApp programs will share the same Terminal Services session. http://technet.microsoft.com/library/cc755055.aspx

Data and User Settings: Utilizes folder redirection and roaming profiles to enable you to make the user’s personal profile and data available dynamically on any authorized PC, and to back up personal profiles and data to the datacenter. http://technet.microsoft.com/library/cc732275.aspx
