Store .vhd's on Windows Storage Server RRS feed

  • Question

  • I am looking to create a virtual environment for my business but I don't have the money for an iSCSI SAN.  Is it possible to buy a Server that has Server 2008 with Hyper-V and store all of the .vhd's on Windows Storage Server 2003 R2?  I run .vhd's across a network in my lab environment and haven't had any issues other than it is slower than DAS or iSCSI but it doesn't perform too bad on a gigabit network.  Has anyone tried to do this before and/or is it possible.  My vendor told me it is impossible but they also said that Windows Storage Server 2003 R2 doesn't support Exchange 2003 either.  Any help is greatly appreciated.

    Thanks,

    Windows Storage Server family now includes iSCSI target capabilities, and the iSCSI initiator is all free on the Hyper-V enabled Windows Server 2008 box

    The Windows Server 2008 based version of Storage Server is not yet released, but you can still do iSCSI

  • It is indeed possible to store vhds on a NAS.

    See http://blogs.technet.com/josebda/archive/2008/06/24/storing-windows-server-2008-hyper-v-files-on-an-cifs-smb-file-share.aspx

    Of course, performance will be slower as compared to some other options like iSCSI. Also, some workloads within the vhd will behave better than others e.g. a transactional workload runs the risk of a lengthy recovery process.

    As Jose points out in his blog, using a Windows Server 2008 based NAS gives you the extra advantage of using SMB2 between the Hyper-V and NAS boxes. This can add some speed, but again it depends upon a lot of factors

  • Hi,

    I have recently implemented the environment you have talked about. Two Hyper-V hosts, NAS back-end using Windows storage server 2003R2 x64, a handful of virtual Windows 2008 servers delivering AD, File&Print, sharepoint, management SW, & Exchange 2007. There have been some mixed results.........Firstly had to introduce an additonal 'physical' stand-alone domain controller. Lots of 2008 blue screens otherwise. 

    http://blogs.dirteam.com/blogs/sanderberkouwer/archive/2008/08/13/active-directory-in-hyper-v-environments-part-1.aspx

    Also the number of virtual machines per processor when virtualising Exchange 2007 is dramatically reduced. Single Processor HP DL360 with a Quad core chip has not been able to support anything more than the Exchange instance and one other 2008 virtual instance. Not Good.

    Other limiting factors have included not being able to present SCSI devices connected to the host to virtual machines (Tape drive in this instance).

    Snap shots have worked OK, backups have been hit and miss.

    Jared Humiston ...Have you had a differing results.

     

    Thanks
