ABSTRACT:
The present invention provides an architecture and method for increasing the performance and resource utilization of networked storage architectures by use of hardware-based storage element mapping. The architecture utilizes a customized programmable processing element to map host read or write commands to physical storage element commands. The present invention uses a plurality of data structures, such as tables, to map host read and write commands to physical storage elements. The hardware-based storage element mapping controller uses the tables, including a mapping segment descriptor table, to map from global address space addresses to physical storage element addresses.
