Abstract
Systems and methods for an architecture for optimizing execution of storage access commands is disclosed. The architecture enables a storage subsystem to execute storage access commands while satisfying one or more optimization criteria. The architecture thereby provides predictable execution times of storage access commands performed on a storage subsystem. In order to optimize execution of storage access commands, in one embodiment the host system sends a calibration request specifying a storage access command and an optimization criterion. In response to the calibration request, the storage subsystem determines the execution speeds of the storage access command within the non-volatile memory storage array and selects at least one region within the non-volatile memory storage array having the execution speed that satisfies the optimization criterion. Subsequently, when the host system desires that a storage access command be executed in satisfaction of the optimization criterion, the storage subsystem executes the command within the selected region.
