摘要

本文研究了采用闪存和磁盘驱动器的混合存储系统中存储空间的有效管理问题。闪存驱动器和磁盘驱动器在读写行为上表现出不同的性能特征。我们提出了一种在这种混合存储系统中平衡闪存和磁盘驱动器之间工作负载属性的技术。本文提出的方法基于存取模式自动、透明地管理数据块在闪存和磁盘驱动器之间的迁移。本文通过实际实验，介绍了该方法的设计和在Linux测试平台上的评估。

Managing storage space in a flash and disk hybrid storage system

This paper considers the problem of efficiently managing storage space in a hybrid storage system employing flash and disk drives. The flash and disk drives exhibit different performance characteristics of read and write behavior. We propose a technique for balancing the workload properties across flash and disk drives in such a hybrid storage system. The presented approach automatically and transparently manages migration of data blocks among flash and disk drives based on their access patterns. This paper presents the design and an evaluation of the proposed approach on a Linux testbed through realistic experiments.
