Introduction to the Dorado HyperMetro feature


HyperMetro creates active-active relationships between two data centers so that both the data centers are running and carry the same host services concurrently. A mutual backup relationship is set up between the storage arrays in the two data centers. If the storage array in one data center malfunctions, the storage array in the other data center automatically takes over services without data loss or service interruption, improving the data center serviceability and system resource utilization.
