Interoperability with existing and previous generations of the DS8000 series
Remote mirroring solutions use Fibre Channel as the communications link between the primary and secondary storage systems. The Fibre Channel ports used for remote mirror and copy can be configured as either a dedicated remote mirror link or as a shared port between remote mirroring and Fibre Channel Protocol (FCP) data traffic.
The remote mirror and copy solutions are optional capabilities
of the DS8870 and are compatible with previous
generations of DS8000. They are available as follows:
- Metro Mirror indicator feature numbers 75xx and 0744 and corresponding DS8000 series function authorization (2396-LFA MM feature numbers 75xx)
- Global Mirror indicator feature numbers 75xx and 0746 and corresponding DS8000 series function authorization (2396-LFA GM feature numbers 75xx)
Global Copy is a non-synchronous long distance copy option for data migration and backup, and is available under Metro Mirror and Global Mirror licenses or Remote Mirror and Copy license on older DS8000, or ESS systems.
