The embodiment of the invention takes the switch as a carrier, configures the photoelectric interface and adds a function of recording the port identification of the connected equipment in the system firmware.
The two servers and the two sets of storages are respectively connected with equipment ports of the disaster recovery module, the equipment ports of the disaster recovery module provide two ports, namely an optical fiber port and a network port, the identification of the optical fiber port is a WWN number, the identification of the network port is an IQN number, for example, the two servers and the two sets of storages are respectively provided with port identifications, the port identification of the Server1 is WWN1/IQN1, the port identification of the Server2 is WWN2/IQN2, the port identification of the Storage 35 1 is WWN3/IQN3, and the port identification of the Storage2 is WWN4/IQN 4. After the server is connected to the disaster recovery module, the disaster recovery module can record the port identifier of the server connection, and the storage is the same.

When a server fails, a new server in the same system is connected to the disaster recovery module, and the disaster recovery module covers the original server port identifier to the port of the new server, so that the original mapping can be ensured without interruption without any configuration, and the purpose of rapidly recovering services is achieved. The Server1 and the Server2 are configured identically, only the Server1 and the Storage1 are mapped currently, when the Server1 fails, the Server2 is started to be on-line, and the disaster recovery module covers the port identification WWN1/IQN1 of the Server1 on the port of the Server2, so that for Storage, the mapping of the front end is not changed, and the service is not interrupted.
Similarly, when two sets of storage are configured identically, and one set of storage fails, the other set of storage connected to the disaster recovery module can immediately acquire the port identifier of the failed storage, so that service is ensured not to be interrupted. The Storage1 and the Storage2 are configured identically, the current Server1 accesses the Storage1, when the Storage1 fails, the Storage2 starts to be online, and the port identification WWN3/IQN3 of the Storage1 can be covered on the Storage2 through the disaster recovery module, so that the mapping is not changed, and the continuity of the service is finally guaranteed.
