NFS Storage

In an NFS storage repository (SR), VM images are stored as thin-provisioned VHD format files on a shared NFS target. Existing NFS servers (that support any version of NFSv3 or NFSv4 over TCP/IP) can be used immediately as an SR for virtual disks.

NFS SRs can be shared, allowing any VMs with their virtual disks in an NFS VHD storage repository to migrate between servers in the same resource pool.

Since virtual disks on NFS SRs are created as sparse, ensure that there is enough disk space on the SR for all required virtual disks.

To configure an NFS SR

  1. Open the New Storage Repository wizard: click New Storage on the toolbar.
  2. Select NFS as the physical storage type, then click Next.
  3. On the Name page, enter the name of the new SR. By default, the wizard generates a description of the SR. This description includes a summary of the configuration options that you select as you progress through the wizard. To enter your own description, clear the Auto-generate description based on SR settings check box and type in the Description box. Click Next to continue.
  4. On the Location page, specify the NFS storage target details:
    • Share Name The IP address or DNS name of the server and the path. For example, server:/path where server is the DNS name or IP address of the server computer, and path is the directory used to contain the SR. The NFS server must be configured to export the specified path to all servers in the pool.
    • Advanced Options You can enter any additional configuration options here.
    • NFS Version Select the NFS version used by the SR.


      If the underlying storage array does not support NFSv4, NFSv3 is used to mount the share.

  5. Click Scan to have the wizard scan for existing NFS SRs in the location you specified.
  6. The New Storage Repository wizard lists any existing SRs which are not already attached. You can select an SR from the list and attach it as the new storage repository. click Reattach an existing SR and select the SR from the list, then click Finish.
  7. If no existing SRs are found, simply click Finish to complete the new SR configuration and close the wizard.
