From the Advanced Backup Configuration tab of the dashboard, an administrator can add the following supported NAS systems if at least one NDMP Accelerator node is deployed:   

  •          EMC Celerra, EMC Unity, or EMC VNX     
  •          EMC Isilon     
  •          NetApp filer     
  •          Oracle ZFS     
    This view also allows an administrator to edit or delete an existing connected NAS system.   
  1.         From Advanced Backup Configuration > NAS page, click Add.     
  3.         Select the NAS Type, Encoding Scheme, and NDMP Accelerator.     
  5.         Type the NDMP Account Name, NDMP Account Password, and Avamar Account Name.

      Only the following characters may be used in the NDMP account name: a-z       
        (lowercase), '.', '-', and '_'.       
        A green check mark indicates that the NDMP Account Password and Confirm       
        Password field match.
Expected results   
      After adding a NAS system, you can create a protection job for the new system with the Avamar Administrator GUI.
