Windows 2003 SBS R2 - Redundancy question

    質問

  • Hi All,

    We currently have a Proliant ML115 (dont laugh) in our small business environment. We have slowly started growing and I know the server is not going to last forever as its quite a basic model. 

    server environment: Exchange server, file server, 8 workstations connected and 1 client RWW.

    I have a ML350 at home which is better than what my work is using.

    Now my main question, is it possible to provide failover with these two different servers, or is it the same case like PC's where you can only use an image if the hardware is exactly the same?

    Ideally I'd like to have the ML350 as the primary and the ML115 sitting there mirroring everything until the ML350 one day fails over.

  • Yes, I agree wit Setsunaaa.  Here are the steps....

    - Level your ML350 and install Hyper-V Server 2008 R2, which is free and comes with clustering.
    - Use SCVMM 2008 R2 to do a P2V conversion of SBS2003
    - Run the new VM on the ML350
    - When you are confident your new system is running well, level the ML115 and install Hyper-V Server 2008 R2
    - Create a mirror of volume holding the VHD file using something like SteelEye DataKeeper Cluster Edition so that it continuously replicates to the ML115
    - Cluster the Hyper-V resource for easy switchover and failover.

    You can do the same thing without the replication, but you will need to get some shared storage.  However, in that configuration your shared storage becomes a single point of failure, so you better have a good backup plan or replication for your shared storage.

  • The only way I know to create an SBS2003 with real failover is to create an hyper-v cluster and run the sbs2003 virtualized (don't forget /usepmtimer in bootoptions of sbs2003 or you will have funny effects). We've done that quite a few times now, works without probelms. But it is not officially supported my MS due to known possible side effects with the virtualised hardware timers (hence the need for /usepmtimer).
    Everything else is manually with a lot of work, i.e. make the OS being able to boot on both machines (RAID-Controller driver problem mainly), and then create an image backup which you will use once the main machine failed. Ugly, works, but I would not recommend to have the old-slow machine as backup.

  • Thankyou both for your help, greatly appriciated. Sorry for the delayed reply.

    So it seems like quite a long process from what you have suggested. It is definatly something I want to do in the near future.

    I'm currently downloading Hyper V 2008 R2 as we speak.

    Forgive my ignorance but when you say "Level your ML350" what do you mean.

    Are there any other methods out there for this senario?

  • In case anyone else is trying to do this, I've just gone through the kind of insane trial-and-error process of installing SCVMM on Hyper-V Server 2008 R2. I'm trying to do a P2V with my Server 2003 installation, which is the only server we have. This means that SCVMM 2008 won't install on it, so it has to install on the Hyper-V server. Here are my notes:

    • Download Hyper-V Server 2008 R2
    • Download the evaluation version of Microsoft System Center Virtual Machine Manager 2008
    • Download the Windows Automated Installation Kit 2008
    • Install Hyper-V Server 2008 R2 on a machine
    • On Hyper-V Server, it may say no network adapters found
    • Download your network card drivers onto a USB stick and insert it into the Hyper-V server
    • In the command line on the Hyper-V server, go into the drivers directory on the USB stick and run "pnputil -i -a .\*.inf", which will install the network drivers
    • In the blue startup menu, do the commands necessary to join your domain
    • In order to install SCVMM, you need .NET 2.0 and 3.0. These come with the SCVMM installer, but you can't install them that way because the OS is a "core" edition and has no GUI (aka Explorer). Luckily, it's actually installed already, but it's disabled.
    • To enable .NET, type this in the Hyper-V server's command line: DISM /Online /Enable-Feature /FeatureName:NetFx2-ServerCore
    • Do it again with NetFx2-ServerCore-WOW64
    • Do it again with NetFx3-ServerCore
    • Install the Windows Automated Installation Kit
    • Finally, install SCVMM

    Hopefully this saves some people the 5 hours it took me to figure all this out!

    • Download Hyper-V Server 2008 R2

    You could have done it MUCH easier: Server 2008 R2 (including enterprise!) runs 60 days without needing to enter a key. SCVMM runs 180 days without needing to enter a key. Then you have a GUI and everything is much easier.

    60 days unlimited demo versions should be enough to do the P2V conversion. Those 60 days are also good for learning hyper-v clustering before you actually implement it at a customer.

    MY way to do a P2V conversion is usually: disk2vhd http://technet.microsoft.com/en-us/sysinternals/ee656415 - SCVMM is along my last resort, especially since it leaves an unremovable network adapter in the virtual system which is a clone-replacement of the once existing physical adapter (including the mac address and card name). Can cause network fun if you plan to reuse the machine for something else (like a NAS or whatever).
