There are specific configuration requirements to partner two systems over native IP links connected directly or via Ethernet switches.The topics provided here describe the configuration settings that are needed for IP partnerships.
Lenovo Storage V7000 already supports remote copy over Fibre Channel. Remote copy over native IP provides a less expensive alternative to using Fibre Channel configurations.
Partnership over native IP brings with it changes to some fundamental assumptions in that there is no name server in an Ethernet fabric to detect and discover remote copy ports. There are specific configuration settings such that the local and remote systems can discover each other's remote-copy capable IP addresses. TCP/IP sessions can then be set up across those IP addresses to establish a partnership.
