HyperMetro ensures real-time synchronization of data between storage arrays at two sites through the real-time cross-site data mirroring function. When the data center array receives write I/O, it needs to record the write log. In the log, only the address information is recorded, and the specific write data content is not recorded. The log is recorded in a memory space with power- failure protection for good performance.
