HyperMetro guarantees real-time data synchronization between the storage arrays of the two sites through the real-time data mirroring function across sites. The data center array needs to record the write log when it receives the write I/O. Only the address information is recorded in the log, and the specific write data content is not recorded. The log is recorded in the memory space with power-down protection capability to obtain good performance.
