A remote management system with adaptive management mechanism is disclosed, by using an adaptive feedback session management decision (AFSMD) server to connect a plurality of clients and a plurality of cluster nodes respectively. AFSMD server includes a session ID map manager for recording mapping between session and cluster node forwarded to; a decision grade producer, for producing a decision grade to determine the session management manner required for the current session; a session connection number query (SCNQ) for communicating with a storage to obtain a total connection number of a client; a cluster node communication interface, for communicating with cluster nodes and for information cluster nodes if session needs duplication; and a session management decision controller for overseeing the entire session management decision flow to achieve higher efficiency.
