  • Virtualization of I/O adapter resources
    Patent number: 7818459
    Abstract: A method and apparatus relates to hardware-to-hardware data transmission in computer systems, and in particular, it relates to method and system for operating I/O adapters attaching either one or more computing devices to an I/O periphery, to a network, or to other computing devices. It is proposed to operate a memory local to the network coupling adapter as a cache memory relative to a system memory associated with the one or more computing devices for storing transmission control information.
    Type: Grant
    Filed: October 31, 2007
    Date of Patent: October 19, 2010
    Assignee: International Business Machines Corporation
    Inventors: Gerd Konrad Bayer, Wolfgang Eckert, Markus Michael Helms, Juergen Maergner, Christoph Raisch, Thomas Schlipf, Klaus Theurich

  • Processing channel subsystem pending I/O work queues based on priorities
    Patent number: 6651125
    Abstract: Asynchronous requests, such as input/output (I/O) requests, within a coprocessor of a computing environment are managed. The management of the asynchronous requests is based on priorities associated with the asynchronous requests. This management includes, for instance, selecting an asynchronous request to be processed using a priority scheme, and/or affording resources to the asynchronous requests using a priority scheme.
