Abstract
A block storage memory management scheme. According to the disclosed embodiments, a memory list of data is generated from a set of address ranges, a descriptor is created to interact with the memory list, and data is retrieved by preparing the memory specified by the descriptor for an input/output operation, performing the operation, and deleting the descriptor. Memory mappings are delayed as long as possible to enhance the performance of the system, particularly for RAID applications.
