Easily add additional disk drive

    Scott,

     

    Thank you for your comment.  We have not done extensive testing on VMs with more then one drive.  We know what will or won't work within an account but need to investigate further the implications for sharing and permalinks.  We would also like to have some automation for extending the partition of the existing drive.  What tool do you recommend using to partition the free space into an additional drive?

    Hey Chris -  

    Sorry I don't.  I just do it manually through Server Manager after adding more disk space to a VM.  I think it could be scripted and if I had to do it frequently, I probably would have figured that out by now.

    I'd be happy to beta test it if you find a solution.  If I find a way to script it I'll let you know.

    Scott,

    Yes it can be scripted.  There are a few tools, and just windows commands, however the solution is OS dependent which makes it hard to scale.  Thank you for the feedback, keep it coming!

    Hi Scott (Chris)

    How did you add a hard drive?

    And what will be the benefit?

    For an - physical - SQL server it is always best to have maybe three drives but does this also count for a VM?

    Hi Soeren -

    I'll answer second question first and then explain how to do this.  From a technical perspective, since the drives are all virtual I don't know if there would be any benefits from a performance perspective.  However, I am a firm believer in trying to model and keep your DEV / QA environment configurations as close to your production configuration as you can.  Therefore, I would recommend allocating disk space to the VM and then partitioning the drive space from within the VM to mirror the configuration of your production servers.  Production environment might be sized differently but try to keep the logical configuration the same.

    Now, how to do it.  Scott Petri from CloudShare has done a nice job demonstrating this here  https://support.cloudshare.com/entries/20848008-increasing-disk-size

    I hope this helps.  

    Take care,

    Scott

    Thank Scott, I´ll try that out.

    Chris, can you answer the question re. performance?

    Hey Soeren, having a multiple drives, or in the virtualized case like this - partitions - I do not see there being a boost in performance.  

    Like Scott mentioned above, the real benefit is in mirroring your environment on CloudShare to match your Production environment.  Getting down into the technical side, the virtual disk in our data center is part of one larger disk.  So any changes you make to a single VM's disk, it is still all part of one physical, logical and contiguous drive.  

    You can either assign added disk space to the main partition or assign it its own partition and drive letter.

    Okay Scott
    I had just hoped that I could achieve the same performance benefit in a VM as with a physical server.
