Methods, apparatus and computer program products implement embodiments of the present invention that include receiving a storage command from a host computer to retrieve first data from a specific physical region of a storage device, and responsively retrieving second data from one or more additional physical regions of the storage device based on a logical mapping managed by the host computer. The second data is conveyed to a cache. In some embodiments, the logical mapping is received from the host computer prior to receiving the storage command. In alternative embodiments, the logical mapping is retrieved from the storage device prior to receiving the storage command.

A computer system, method, and program product for dynamically allocating storage bandwidth in an exchange is provided. The method provided creates, by an exchange server, a total inventory of resources for auction, whereby the total inventory of resources for auction includes resources from at least one provider. The total inventory of resources for auction is broadcast to at least one bidder. The amount of a resource is awarded to the at least one bidder at an end of a bidding interval, based on a bid provided by the at least one bidder during the bidding interval, where the amount of the resource is a portion of the total inventory of resources for auction.

According to one embodiment of the present disclosure, a method for testing a boot image is disclosed. The method comprises creating a test boot image for a first logical partition, creating a second logical partition wherein the second logical partition is a duplicate of the first logical partition, initiating a boot sequence for the second logical partition using the test boot image, and returning a result of the boot sequence to a requestor.

A system for balancing component load. In response to receiving a request, data is updated to reflect a current number of pending requests. In response to analyzing the updated data, it is determined whether throttling is necessary. In response to determining that throttling is not necessary, a corresponding request to the received request is created and a flag is set in the corresponding request. Then, the corresponding request is sent to one of a plurality of lower level components of an input/output stack of an operating system for processing based on the analyzed data to balance component load in the input/output stack of the operating system.
