TrueCopy operations are carried out between primary and secondary storage systems connected by a Fibre Channel or iSCSI interface. An NVMe-oF 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 two or more independent connections are recommended for hardware redundancy.
