Applies to

  • ONTAP 9
  • Microsoft Hyper-V
  • SMB/CIFS

Answer

  • Hyper-V over SMB support nondisruptive operations (NDOs).
  • With a Hyper-V over SMB solution, the application servers and the contained virtual machines or databases remain online and provide continuous availability during the ONTAP upgrade.
  • Continuously available CIFS shares (CA), accessed by Hyper-V Server clients using the SMB 3.0 protocol, do not need to be terminated before upgrading or downgrading.
