  • Publication number: 20190278659
    Abstract: A method, computer system, and a computer program product for enhanced application write operations is provided. The present invention may include performing a write operation by an application node. The present invention may then include committing the write operation to a local buffer cache. The present invention may then include sending the application node an indication that the write operation was successful. The present invention may then include flushing the local buffer cache to a disk based on a buffer flush trigger, and the present invention may lastly include sending a Remote Procedure Call (RPC) to at least one gateway node, wherein functionality of the gateway node is located on different physical nodes which are separated from the application node over the network.

  • Publication number: 20190236050
    Abstract: Data is migrated from a source storage device to a destination storage device using tape media. Both the source storage device and the destination storage device utilize disk drives to store data. A portion of data is detected migrating to the tape media. Metadata of the portion of data is changed to identify the portion of data as residing on the tape media. A prefetch command for the portion of data is detected. It is determined that the portion of data is stored on the tape media. In response to determining that the portion of data is stored on the tape media, the prefetch command is executing without recalling the portion of data to the disk drives. Instead, the portion of data is read directly from the tape media.

  • Patent number: 8493211
    Abstract: A method, apparatus, and computer program product for providing event indications in an event model in a manner so that indication storms resulting from excessive indication generation and delivery is prevented. An object behavior change in an information model corresponds to an event. An indication of interest is sent to a listener process when the detected object behavior change corresponds to a specified top level indication class in an indication class hierarchy.
