Abstract: This paper proposes a novel buffer management model for network storage device(Service-oriented Buffer Management model, SBM). It supports not only configurable buffer management policy but also configurable policy-based buffer allocation mechanism. Compared with buffer management module in general-purpose OS, SBM enables I/O performance optimization targeted for specific storage application, and facilitates realizing storage QoS across multiple storage applications.

Key words: network storage device, buffer management, buffer allocation

摘要： 给出一种适用于网络存储设备的面向存储服务的新型缓存管理模型，它支持可配置的缓存管理策略和可配置策略的缓存分配机制。与通用操作系统中的缓存管理模块相比，该模型的主要优点是使能针对具体存储应用的性能优化，使能多个存储应用之间的数据访问 QoS控制。
