一种双控存储系统中IO缓存模块设计方法

摘要

IO caching is an important bottleneck in computer systems. Light linux file page caching mechanism to create a stand-alone IO caching framework and modules to achieve a dual control system of the IO cache memory handling mechanism. On this basis, build a storage system has good stability and good reading and writing performance. Finally, the next steps in improving the design ideas were initially described.%IO缓存处理是计算机系统的一个重要瓶颈.参照Linux文件页高速缓存机制,创建了独立运行的IO缓存框架和模块,实现了双控存储系统上的IO缓存处理机制.在此基础上构建的存储系统具有较好的稳定性和良好的读写性能.最后对该设计方法的下一步改进思路作了初步阐述.
