TrueCopy operations are carried out between primary and secondary storage systems. An NVMe-oF or NVMe/TCP interface is not supported. The data path, also referred to as the remote copy connection, connects ports on the primary storage system to the ports on the secondary storage system. Ports are assigned attributes that allow them to send and receive data.
One data path connection is required, but you should have two or more independent connections for hardware redundancy.
For details about interfaces that can be used as data paths, see Data path requirements and configurations.
