Question No. 2

HyperMetro uses cross-site real-time data mirroring to ensure real-time data synchronization between the storage arrays at two sites. Upon receiving a write I/O, the storage array in a data center generates a write log. In the log, only address information is recorded, but data is not recorded. To ensure performance, log information is recorded in memory space capable of power failure protection.
