    摘要: A method, system and computer program product for minimizing read response time in a storage subsystem including a plurality of resources is provided. A middle logical block address (LBA) is calculated for a read request. A preferred resource of the plurality of resources is determined by calculating a minimum seek time based on a closest position to a last position of a head at each resource of the plurality of resources, estimated from the middle LBA. The read request is directed to at least one of the preferred resource or an alternative resource.

    摘要: An apparatus, system, and method are disclosed for parallelizing access to shared assets. A size module determines if a size of a first spoke of a plurality of spokes is greater than a low threshold. The spokes are arranged in a circular order wherein a global spoke pointer identifies the first spoke as a current spoke. Each spoke is configured as an asset queue. A request module requests an asset from the first spoke if the size of the first spoke is greater than the low threshold. A rotate module rotates the global spoke pointer to a second spoke of the plurality of spokes if the size of the first spoke is not greater than the low threshold, wherein the second spoke becomes the current spoke.
