Abstract
数据量的激增给计算机存储系统带来严峻的性能挑战。固态盘作为新型存储介质,已被企业级存储系统和数据中心广泛使用,但简单地将传统存储软件应用于固态盘将带来一些新的问题,如将磁盘阵列技术应用于固态盘会加剧固态盘的垃圾回收操作所引发的性能波动性问题,将传统键值(KeyValue,简称KV)存储系统部署于固态盘上也可能造成存储效率低下等问题。本文分别以黑盒和白盒的使用角度,分别对固态盘阵列和基于固态盘的KV存储系统进行研究。 首先,对固态盘阵列的最优分块大小进行研究,理论分析和真实设备的性能测试结果表明,固态盘阵列的分块大小会对固态盘阵列的读写性能产生较大影响。基于分块大小与真实应用负载的读写密集特性...
 
With rapidly increasing of data, computer storage systems encounter serious performance challenge. As new storage media, Solid State Drives (short for SSDs), have been widely used in enterprise storage systems and data centers. However, simply applying traditional storage software to SSDs will bring some new problems, such as the performance variability issue caused by Garbage Collection (short fo...
