How do I attach a contigous 8TB drive and have a fixed drive letter in a VM?

    Question

  • I have created the correct VM configuration that allows for up to 8TB. I can see you can create a blob of max size 1024 GB, I would think then you need to create 8 x 1024 GB individual blob storage files. Does this make sense?

    My question then is how do you create a contiguous 8 TB drive that has a fixed drive letter in a VM?

    Potentially using storage manager etc?

    It does not seem obvious or am I missing something.

    thx

  • Hi,

    There are two methods to make aggregation of your disks:

    - Using the spanned disk option directly from the Storage Manager (If you are using Windows 2008 R2)

    - Or using the recommended option, which is the Storage Spaces. The following is the script of how to create an continuous 8 disks volume upon a Storage Spaces pool (Windows Server 2012 and later)

    The following is the script i use to create an 8 disks storage pool and Vdisk

    Import-Module Storage
    # Get the disks which support pooling
    $Disks = Get-PhysicalDisk -CanPool $true
    Write-Output "List of disks with CanPool True"
    $Disks
    $DiskCount = $Disks.count
    Write-Output "Starting D8"
    $SPFriendlyName = "POOL8" 
    $VDFriendlyName = "VD8" 
    
    Write-Output "Getting Storage Subsystem"
    
    $s = Get-StorageSubSystem -FriendlyName *Spaces*
    
    Write-Output "Getting Physical Disk"
    
    #If your disks are not continous, you can get their names and replace each disk name here by the real name
    $Disks = Get-PhysicalDisk  -FriendlyName $DisksNames.get(0),$DisksNames.get(1),$DisksNames.get(2),$DisksNames.get(3),$DisksNames.get(4),$DisksNames.get(5),$DisksNames.get(6),$DisksNames.get(7)  
    
    Write-Output "Creating Storage Pool"
    
    $StoragePool = New-StoragePool -FriendlyName $SPFriendlyName -StorageSubSystemFriendlyName $s.FriendlyName -PhysicalDisks $Disks
    
    Write-Output "Creating  Virtual Disk"
    
    New-VirtualDisk –FriendlyName $VDFriendlyName -ResiliencySettingName Simple –NumberOfColumns $Disks.Count –UseMaximumSize –Interleave 256KB -StoragePoolFriendlyName $StoragePool.FriendlyName
    
    Write-Output "Getting Virtual Disk"
    
    $VD = Get-VirtualDisk –FriendlyName $VDFriendlyName
    
    Write-Output "Initialzing the Disk"
    
    
    
     Initialize-Disk -VirtualDisk $VD -PartitionStyle GPT 
    
     Write-Output "Creating the Partition"
    
     New-Partition -DiskId $VD.UniqueId -DriveLetter E –UseMaximumSize
    
     Write-Output "Formating the Volume"
       
     
     Format-Volume -DriveLetter E  -NewFileSystemLabel E -FileSystem NTFS -Force -Confirm:$false
