'Data storage system, method, controller, and design structure for realizing performance optimization on storage adapters by performing hardware operations collectively

摘要

A data storage system comprising: a controller (100) comprising: a variety of hardware engines (120); a processor (104), wherein a plurality of instruction blocks (400) of firmware (304) are selectively arranged in a predefined chain, including a plurality of concurrent instruction blocks; wherein the concurrent command blocks are executed concurrently by respective hardware engines (120) and completed in any order, and wherein a next command block in the predefined chain is started under hardware control without any Hardware Firmware (HW-FW) lock being notified of the concurrent execution of the concurrent command blocks and the processor is notified if the hardware engines (120) are the predefined chain have executed.
