发明名称 A SYSTEM FOR, AND METHOD OF, OFF-LOADING NETWORK TRANSACTIONS FROM A MAINFRAME TO AN INTELLIGENT INPUT/OUTPUT DEVICE, INCLUDING OFF-LOADING MESSAGE QUEUING FACILITIES
摘要 <p>A system for, and method of, off-loading network transactions from a main frame to an intelligent input/output device, including off-loading message queueing facilities. A storage controller (102) has a processor and a memory, in which the controller receives I/O commands having corresponding addresses. In the controller memory, a communication stack (116) is provided for receiving and transmitting information on a network (106). In addition, a message queue facilities (MQF) (114) is provided that cooperates with the communication stack (116) and that is responsive to a message queue verb. The MQF (114) causes the communication stack (116) to provide information to a queue in the MQF or causes a queue in the MQF to provide information to the communication stack (116). Moreover, interface logic (105) is provided in the controller memory and is responsive to the I/O commands, to determine whether an I/O command is within a first set of predetermined I/O commands. If so, the interface logic (105) maps the I/O command to a corresponding message queue verb and queue to invoke the MQF (114). In this fashion, the MQF (114) may cooperate with the communication stack (116) to send and receive information corresponding to the verb, while off-loading the processing from a computer client (e.g., a mainframe) of the storage controller.</p>
