提出了一种采用RAMdisk的混合存储系统,在计算节点的并行文件系统的元数据服务器和对象存储服务器组件中设置不同用途的RAM-disk,用于缓存各种访问模式的文件并提高系统的读写性能.结果表明,采用RAM-disk的混合存储系统可以明显提高系统的读写性能,同时可提高系统的可用性和可维性.
A hybrid storage system with RAM-disk is proposed. It was a novel method which can reduce the latency of I/O by inserting a RAM-disk in the different nodes of the system for caching the I/Ofiles. The result of experiment implies that the hybrid storage system with RAM disk can improve the perform ance and availability of file system.
