The storage server includes a processor configured to: generate a plurality of flush write commands based on a write command of first data provided from a host, provide a replication command corresponding to the write command to an external storage server, and receive an operation completion signal of the replication command from the external storage server; a memory storing a program of a log file to which the plurality of flush write commands are logged; and a storage device configured to receive a multi-offset write command including one or more flush write commands logged to the log file, and perform a flush operation on the multi-offset write command. The processor is further configured to provide the multi-offset write command to the storage device based on the log file after receiving the operation completion signal.
