Method and system for optimizing operations on memory device

摘要

A method and system for managing operation streams for multiple memory devices is presented. The method determines cross-dependencies among multiple operations and uses the cross-dependencies to optimize the execution of the operations. Also presented is a method of synchronizing memory devices with little adverse effects on system operations. The method entails sampling the objects in a predetermined order. Since the system is in normal use while the sampling is happening, an operation is received to be performed on at least one target object. A state of the target object is determined. If the target object is in a revising state, revision is performed on the second storage system and the operation is applied to the target object but its application to the second memory device is deferred until the target object is in its final state.
