Three Fibre Channel configurations are supported for TrueCopy:
CCI is used to set port topology.
For direct and switch connections, host I/O response time can be improved on long distance connections (longwave, up to 10 km for direct connection and 100 km for switch connection) by improving the I/O response time between storage systems and by using host mode option 51, the Round Trip Set Up option. Depending on the storage systems you are using, the function must be set either on both primary and secondary systems or only on the secondary storage system.
A Hitachi Vantara-approved channel extender is required.
