The disaster recovery solution of two locations and three centers adopts the "dual-active + synchronous + asynchronous parallel" networking architecture. When the array of production center A fails, the array of production center B continues to provide services. The array of production center records the data difference with production center A, and the asynchrony of the array of production center B to the off-site disaster recovery center will be affected.
