  • Microsoft Virtual Desktop Infrastructure

    Microsoft® VDIimage

    Yeah.. its been three weeks i have posted anything on my blog, just trying to organize some stuff which keeping me really busy these days..

    Anyways.. i don't think i talk enough on this blog about Microsoft VDI aka Virtual Desktop Infrastructure solution.

    Virtual Desktop Infrastructure is a delivery solution where administrators can centralize the user desktop with OS like Windows Vista as Virtual Machines on servers in your datacenter and make these Virtual Desktop workspace available to users via Remote Desktops, Terminal Services or through connection broker like Citrix.

    Why do we need VDI?

    Through virtualization, employees can access their applications and data very safely over a network and the risk of data loss is minimized. On the IT side, virtualization accelerates deployment of new capabilities without needing to acquire new hardware and configure
    components. It also reduces application testing requirements and compatibility issues and simplifies disaster recovery and compliance.

    With Desktop Virtualization, It administrators can decouple layers like Operating System, Application and data from Hardware and store them at centralized servers.


    Microsoft VDI solution comprises of  following Technologies

    Windows Server® 2008 with Hyper-VTM — provides great value with a reliable virtualization platform and integrated management that enables customers to virtualize their desktop infrastructure.

    System Center Virtual Machine Manager 2008 — simplifies the deployment, provisioning, and management of virtualized desktops.

    Windows Server 2008 Terminal Services — virtualizes the presentation of entire desktops or specific applications in a virtualized desktop.

    Microsoft Application Virtualization (App-V) — is part of the Microsoft Desktop Optimization Pack and delivers desktop applications that are never installed, and are dynamically delivered on demand.

    Windows VistaTM Enterprise Centralized Desktop — is a unique licensing option of Windows Vista for VDI

    Microsoft also has a strategic alliance with Citrix to create a Dynamic desktop delivery model. With Citrix Connection broker Virtual Desktops gets created On Demand as user logs in. This way administrators don't have to create Multiple Virtual Machines, they just create a master copy of the Windows Image which gets provisioned as user logs in.

    It works something like this. 

    When user logs in with his thin client PC or Rich Client PC, image                                                                       

    • Connection broker provisions new Virtual Machine with Microsoft System Center Virtual Machine Manager.
    • Microsoft Application Virtualization publishes the application to the newly provisioned Virtual desktop
    • User gets his profile with Profile Virtualization.

    So three layers Operating System+Application+Data gets combined together and presented to the user.

    This way user always have access to his desktop, his application and his data no matter what device he is using,

    He can use any PC in office or even from home PC. he will always have access to his Desktop.

    So this was just an Introduction, i will get back with some advance information on Microsoft VDI solution very soon.

  • Hyper V R2 + SCVMM R2: Introducing Storage Migration

    Hyper V R2 + SCVMM R2 are better together, Can they be any more better….???

    Yes, they can and Teams here at Microsoft are constantly making it better and better than the best.

    Today Edwin Yuen, Senior Technical Product Manager at Microsoft's Integrated Virtualization team introduced a much awaited feature in System Center Virtual Machine Manager 2008 R2 called Quick Storage Migration(QSM) in a great post on Microsoft Virtualization official blog.

    In addition to Live Migration, I get to hear a lot about storage migration when i interact with our partners and customers, How can they migrate the Hyper V storage (VDHs) from 1 SAN box to another.                                                                                                           Lots of customer uses Shared storage like SAN to store their VMs VHDs to create a failover cluster to make high available VMs and when it comes to move the Storage from 1 SAN box to another storage location, that causes a considerable amount of downtime.


    Now with System Center Virtual Machine Manager R2 and Hyper V with Server 2008 R2, You can do the storage Migration with less than 1 minute of Downtime.

    You know the best part i like about this post and this technology, How it helps our customers to further lower the TCO.

    In Edwin’s words,

    One thing our customers have been telling us loud and clear is that they are very, very happy we are offering Live Migration for FREE with Hyper-V R2. With Quick Storage Migration, we knew we had another opportunity to drive down the costs for storage migration capability that has been largely priced out of the reach of most customers. Specifically, VMware Storage VMotion is only available in their Enterprise/Enterprise Plus SKUs ($2875 & $3495 per processor respectively). Contrast this with the fact that Quick Storage Migration is included with System Center Virtual Machine Manager 2008 R2 both the Enterprise Edition and the Workgroup Edition which will be available for starting at about $500.

    For a small five node cluster consisting of two and four processors servers, that would cost at a minimum:

    Storage migration

    That's customer focus.”

    Isn’t this piece of technology so irresistible and adds so much value to your existing investments with so lower cost??

    I strong recommend you to please read the full blog post of Edwin Yuen to understand how Microsoft Quick Migrations works and how it can benefit business continuity HERE

    And do let me know your feedback and comments. :-)
