Abstract

See full text

An information handling system may include at least one processor and a non-transitory memory coupled to the at least one processor. The information handling system may be configured to implement a disk manager configured to receive a command to perform a block input/output (I/O) job at a first physical storage resource. The disk manager may, based on characteristics of the block I/O job, classify the block I/O job as an intensive write. In response to the block I/O job being classified as an intensive write, the disk manager may invoke a speculative I/O aggregator module of the disk manager. The disk manager may create a delta disk image for the first physical storage resource at a second physical storage resource, and redirect the block I/O job to the delta disk image at the second physical storage resource.
