1. In a storage controller having a processor and a memory, in which the controller receives I/O commands having corresponding addresses, a set of processor-executable instructions residing in the memory, comprising:

  • a communication stack for receiving and transmitting information on a network;

    message queue facilities (MQF), cooperating with the communication stack and responsive to a message queue verb, for causing the communication stack to provide information to a queue in the MQF or causing a queue in the MQF to provide information to the communication stack;

    interface logic, responsive to the I/O commands, to determine whether an I/O command is within a first set of predetermined I/O commands and, if so, to map the I/O command to a corresponding message queue verb and queue to invoke the MQF such that the MQF may cooperate with the communication stack to send and receive information corresponding to the verb.
