Configure SMB/CIFS storage for Proxmox Virtual Environment (VE) using NetApp ONTAP. SMB multichannel provides fault tolerance and boosts performance with multiple network connections to the storage system.
SMB/CIFS file shares require configuration tasks by both storage and virtualization administrators. For more details, refer to TR4740 - SMB 3.0 Multichannel.
