Three Fibre Channel configurations are supported for TrueCopy:
Hitachi Device Manager - Storage Navigator or 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.
- VSP G1x00, and VSP F1500: Has to be set on both primary and secondary systems.
- VSP 5000 series, VSP E series, VSP G/F350, G/F370, G/F700, G/F900, VSP G200, G400, G600, G800, VSP F400, F600, F800: Can be set on the secondary system only, but it is advantagous to set HMO51 on both primary and secondary systems in situations in which your systems reverse directions (the primary becomes the secondary), for example.
A Hitachi Vantara-approved channel extender is required.
