  • Patent number: 7587531
    Abstract: An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. An input/output subsystem image is identified by an input/output subsystem image identifier, which is used by various programs to designate the particular input/output subsystem image for which an I/O operation is to be performed. An input/output subsystem image includes, for instance, one or more input/output paths. An input/output path of an input/output subsystem image is identified by an input/output path identifier, as well as a physical input/output path identifier.

  • Patent number: 7177961
    Abstract: An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. In response to an operating system image submitting an input/output (I/O) request requesting access to an input/output subsystem image, a determination is made as to whether the operating system image is authorized to access the input/output subsystem image. In response to the access being authorized, the I/O request is authorized.

  • Patent number: 7130938
    Abstract: An input/output subsystem of a computing environment is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. An input/output subsystem image includes one or more communications adapters used for communicating within the computing environment. A communications adapter is identified by hardware of the computing environment by using a first identifier, and it is identified by a program of the computing environment by using a second identifier. The identifiers can be of different sizes.

  • Patent number: 6963940
    Abstract: The utilization of various individual components of a channel is determined in order to learn which portion of a channel is busy and to what extent that portion is busy. The determination of a component's utilization is dependent on the type of component, as well as the operational characteristics of that component.

  • Patent number: 5613068
    Abstract: A multi-system interconnect facility in which each central processor complex in the system has an assigned storage space for each other central processor complex in the system for use in communicating with each other central processor complex. The allegiance or association of systems to particular storage spaces is established when each system is initialized and enables a simple interface between user program(s) and message passing hardware consisting primarily of instructions for moving control and data blocks between the program addressable space and the hardware addressable space.

  • Patent number: 5600805
    Abstract: Enables any OS of plural OSs within any of plural logical-resource partitions (LPARs) of a CEC to use interpretive execution for synchronously-executable CHSC (channel subsystem call) commands. A CHSC command authorization mask (CCAM) is provided to control which CHSC commands are allowed to execute interpretively (with pass-through), and which commands are executed with hypervisor intervention (as all prior CHSC commands did). By enabling interpretive execution of those commands which can successfully operate with pass-through, significant system efficiency is obtained. And by disabling interpretive execution for a subset of CHSC commands (which are not allowed to execute with pass-through) potential system failures may be prevented. Thus, interpretive execution may be restricted differently among the OSs in a CEC. Novel CHSC command execution now handles multiple images of shared I/O resources by use of image identifiers, which could not be done before.

  • Patent number: 5548791
    Abstract: A data processing system includes a host processor and host memory means. The processor interacts with a plurality of peripheral units through an I/O system that includes a plurality of channels, one or more I/O processors (IOP's), and control data in a system area of the host memory means. Each channel has an associated busy bit in a vector, and is provided with a one position queue for dispatching work to the channel. Each queue has a bit in a vector indicating its full or empty status. A very efficient algorithm for the assignment of work for peripherals by the IOP's is provided in a system that provides for multiple paths through multiple channels between the host and a particular peripheral using the busy vector and queue vector.

  • Patent number: 5522088
    Abstract: A shared channel subsystem has an input-output element for coupling each of a plurality of input-output controllers to each of a plurality of processor nodes by means of a self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individually phase aligned with the clock signal, providing a cost effective, modular input/output element.

  • Patent number: 5513377
    Abstract: An enhanced input-output element has a self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individually phase aligned with the clock signal to provide a cost effective, modular, broadband, input/output element that can serve economically two channels and is modularly scalable to serve several hundred channels.
