Dynamic Memory Pro Tip – be reasonable with your startup ram

Hyper-V now allows you to configure a startup, minimum and maximum memory limit.  If you are like me – you probably leave the startup ram at the default of 512mb – but you should really consider changing it to better suit your environment.  Here is a quick screenshot from one of my Hyper-V servers: Two things that I have discovered: Some of my virtual machines benefit from having a startup and minimum that is below 512mb.  My FTP server, for instance, is a core installation of Windows server which just acts as an...

Le SP1 de Windows 7 arrive le 22 février

Microsoft vient d'annoncer officiellement la date de lancement du SP1 pour Windows 7 et Windows Server 2008 R2, première grosse mise à jour de son OS. L'annonce est tout ce qu'il y a de plus officielle. Le développement du Service Pack 1 de Windows 7 a été finalisé après une phase bêta menée depuis le mois de juillet 2010. Microsoft l'a dévoilé sur l'un de ses blogs il y a quelques heures seulement, précisant que cette mise à jour s'appliquera également à Windows Server 2008 R2. Le SP1 sera diffusé auprès du grand public à... [Lire la suite]

Tech: Dynamic Memory for Hyper-V, is it worth it for VDI?

Michel Roth, who works for the desktop virtualization division of Quest and runs the Thincomputing.net blog wrote an article titled: “A closer look at the new “Dynamic Memory” feature of Hyper-V: is it worth it for VDI? “. The article details what Dynamic Memory is and especially on what it can do for Virtual Desktop Infrastructures (VDI). Michel earlier wrote an article about the upcoming RemoteFX functionality which will also be released with SP1. Dynamic Memory provides the ability to pool available memory on a physical host and...

Hyper-V Dynamic Memory test for VDI density

Hi, I’m Michael Kleef, senior technical product manager within the Windows Server and Cloud division. As Brad Anderson and I discussed at the TechEd Europe keynote today, Dynamic Memory, a new feature in Windows Server 2008 R2 SP1, can increase Virtual Desktop Infrastructure (VDI) densities by 40% compared to Hyper-V in Windows Server 2008 R2 and also well above a leading industry solution. It’s also not just a benefit to VDI. Our Technology Adoption Program (TAP) customer data also highlights that other server workloads benefit... [Lire la suite]

Enabling Dynamic Memory on Windows Server Standard and Web Editions

With the release candidate build of service pack 1 for Windows Server 2008 R2 you can now enabled Dynamic Memory on the standard and web editions of Windows Server.  However – there is a slightly different process to do this on the various versions of Windows server: Windows Server 2003 / Windows Server 2003 R2 All you need to do for these operating systems is to update the integration services. Windows Server 2008 Here you need to first have service pack 2 installed.  Then you need to install this hotfix:... [Lire la suite]

Guest post: Storage Loves Dynamic Memory

Hi, I’m Alex Miroshnichenko, chief technology officer of Virsto Software. One of the most exciting events of my summer was the announcement of Microsoft Windows Server 2008 R2 Service Pack 1 (SP1). Though still in beta, SP1’s stability has lived up to production standards in Virsto’s test labs. SP1 brings Dynamic Memory to Microsoft Hyper-V.  In practical terms, you should be able to run meaningfully more virtual machines on the same server hardware, since static memory limits are gone. Dynamic Memory also... [Lire la suite]

Parent memory reserve with dynamic memory

Most people I know who have spent a lot of time with Hyper-V have had the experience of accidentally taking too much memory away from the parent partition.  This happens when they start too many virtual machines – and all of a sudden the performance and responsiveness of the parent partition goes down significantly. The response from people who hit this is usually to stop the last virtual machine that they started, to reduce its memory, and then start it up again. This solution has worked in the past – but is no longer an... [Lire la suite]

Six dossiers complets sur la fonctionnalité Dynamic Memory du SP1 de 2008 R2

C’est certainement la fonctionnalité qui fait couler le plus d’encre lorsque l’on évoque le futur Service Pack 1 pour Windows Server 2008 R2. En effet ce prochain SP très orienté virtualisation va apporter un grand changement dans Hyper-V puisqu’il va permettre l’allocation dynamique de mémoire aux machines virtuelles. Pour rappel, il va désormais être possible d’allouer non plus une taille fixe de RAM nécessaire à votre VM mais une fourchette, allant du minimum requis pour démarrer cette VM à la quantité maximal de RAM qu’elle...
