Abstract: Mechanisms are provided for implementing intelligent input/output (I/O) operation completion modes in a high-speed network. An application thread executing on a central processing unit in the data processing system, receives a first indication to enter a mode of operation. The application thread enters the mode of operation, arms an arm file descriptor, and processes further completions that enter the completion queue until a second indication is received indicating that the mode is to be exited. Responsive to receiving the second indication to exit the mode, the application thread exits the mode of operation and disarms the arm file descriptor.

Abstract: Provided are a computer program product, system, and method for prefetching data blocks from a primary storage to a secondary storage system while data is being synchronized between the primary storage and secondary storage. A determination is made of data blocks to prefetch from the primary storage to the secondary controller not yet synchronized from the primary storage to the secondary storage in anticipation of future access requests for the data blocks to the secondary controller while data blocks are being synchronized between the primary storage and the secondary storage over the network. A prefetch command is sent to prefetch the determined data blocks to copy from the primary storage to the secondary controller to make available to future access requests received at the secondary controller for the determined data blocks.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include detecting, on a communications network in a computing facility including a first computer coupled to a second computer via the communications network, an input/output (I/O) request conveyed from the first computer to the second computer. Subsequent to detecting the I/O request, data traffic resulting from the second computer processing the I/O request is identified on the communications network, and network statistics are collected based on the I/O request and the data traffic. Upon detecting a performance degradation of the computing facility, the performance degradation greater than a predetermined amount, heuristics can be applied to the collected network statistics, to identify a cause of the performance degradation and to identify a remedy to the detected performance degradation. In some embodiments, the identified cause and the identified remedy can be presented to a user on a display.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include configuring multiple servers coupled to a network as a software defined storage (SDS) grid. A first given server receives, via the network, an input/output (I/O) request from a host computer, and determines a location of data associated with the I/O request. In some embodiments, each of the servers maintains a local grid data map that store locations for all data managed by the SDS grid. Upon identifying, in its respective local grid data map, that a second given server is configured to process the I/O request, the first given server forwards the I/O request to the second given server for processing, and upon receiving a result of the I/O request from the second given server, the first given server conveys the result of the I/O request to the host computer.
