| 摘 要： | 针对存储系统中的缓存管理单元设计一种区分应用优先级的缓存回收策略,简称PARP.该策略基于分区缓存管理模型,它能够根据应用优先级区分回收缓存资源以实现对各应用缓存分区容量的在线动态调节进而达成应用级缓存管理语义.实验数据表明PARP策略能够在实际系统中有效的支持区分应用优先级,这不仅可以用于实现存储系统的服务质量保证同时也能够改善存储系统的整体性能.

| Abstract: | Presented a priority-based application-level buffer reclaim policy-PARP designed for the buffer management unit in storage system.Based on partitioned buffer management model,it can differentially reclaim buffer resource from multiple applications according to their priorities.This realizes the dynamically adjustment of the application's buffer capacity to provide application-level buffer management semantics.Experiment results show that PARP effectively supports application priority in real system,which ca... |
