Input/output (i/o) interceptor that re-orders a plurality of write i/o into combined with i/o with intelligent flush control logic

Abstract

Inventive aspects include an input/output (I/O) interceptor logic section having an I/O interface coupled with a storage stack. The I/O interface can intercept write I/Os, read I/Os, and flush requests from an application. A temporary write holding buffer can store the write I/Os. A re-order logic section can change an order of the write I/Os, and combine the re-ordered write I/Os into a combined write I/O. An intelligent flush control logic section can receive the flush requests from the I/O interface, communicate write I/O completion of the write I/Os to the application without the write I/Os having been written to a non-volatile storage device, and cause the combined write I/O to be written to the non-volatile storage device responsive to at least one of a predefined Nth flush request from among the plurality flush requests, a threshold amount of data being accumulated, or an expiration of a predefined time period.
