  • Reducing latency in a channel adapter by accelerated I/O control block processing
    Patent number: 7466716
    Abstract: The present invention generally relates to digital network communication, and in particular to processing data according to the InfiniBand™ (IB) Protocol with reduced latency and chip costs in an InfiniBand™ type computer system. ID information in a packet header is obtained before the body of the packet has completely arrived at a receiving Channel adapter. The ID information is used to obtain work Queue Pair Context (QPC) and when needed an associated Work Queue Element (WQE), for operating on the data content of the packet being received.
    Type: Grant

    Date of Patent: December 16, 2008
    Assignee: International Business Machines Corporation
    Inventors: Rainer Dorsch, Martin Eckert, Markus Helms, Walter Lipponer, Thomas Schlipf, Daniel Sentler, Harmut Ulland

  • Channel adapter managed trusted queue pairs
    Publication number: 20060013397
    Abstract: An InfiniBand™ Channel Adapter encrypts or decrypts user data on-the-fly. The user data is read from system memory and encrypted in by the Channel Adapter before sending it to a network. Similarly received data is decrypted on the fly before storing it in system memory. The encryption/decryption keys are preferably stored in a Queue Pair Context storage area of system memory as Public key for sending data and Private key for receiving data.
