  • System for controlling connection requests by each IO controllers storing and managing a request queue wherein additional channel addresses can be added
    Patent number: 5878278
    Abstract: A data processing system includes a central processing complex consisting of one or more processor units, each of the processor units having one or more input/output channels, a transmission medium connected to each of the input/output channels, and one or more peripheral device controllers such as for controlling one or more direct access storage devices (DASD). In systems having more than one input/output channels, it is common to include a switching mechanism connected between the input/output channels and the control devices for enabling connection between one of a number of controllers and one of a number of channels. Each control device will include an automatic frame transmission function which includes apparatus and method for controlling transmission of frames of information between the control device and the channel. A queue of reconnection requests is constructed and a state machine controls the queue.

  • System and method for transferring compressed and uncompressed data between storage systems
    Patent number: 5630092
    Abstract: A system and method are provided for sharing a data stream between a first data storage system in communication with a second data storage system. Meta-data is associated with each record of the data stream. Zero or more records of the data stream are compressed at the first storage system. The meta-data for the compressed data record is updated to indicate that the data record has been compressed. The data stream including the compressed data record with the updated meta-data is sent to the second storage system. The meta-data and the data stream records are stored on a storage device at the second data storage system.

  • Storage management of data for ensuring communication of minimal length data
    Patent number: 5561824
    Abstract: A method and apparatus for ensuring the communication of a minimal length data stream in a system including a host and a storage management device is provided. The method and apparatus includes first and second buffers for simultaneously receiving compressed data and the original data from the host. The system compares the length of the data in the first and second buffers. If the data has expanded, indicating that compressed data is longer than the original data, the original data is provided to the storage media. If the data has not expanded, indicating that the original data is longer than the compressed data, then the compressed data is provided to the storage media.
