Abstract: The preferred embodiment of present invention is directed to an improved method and system for buffering incoming/unsolicited data received by a host computer that is connected to a network such as a storage area network. Specifically, in a host computer system in which the main memory of the host server maintains a I/O control block command ring, and which a connective port (e.g., a host bus adaptor) is operatively coupled to the main memory for handling I/O commands received by and transmitted from the host server, a host buffer queue (HBQ) is maintained for storing a series of buffer descriptors retrievable by the port for writing incoming/unsolicited data to specific address locations within the main memory.
