| 摘 要： | 固态盘具有低功耗、高性能、耐冲击等优势,硬盘具有高容量、低价格等优势.通过改进文件系统的结构,把固态盘和硬盘结合起来,固态盘作为硬盘的大容量缓存,组成一个我们称之为异构盘的异构系统,其性能接近于固态盘,价格却接近于硬盘.同时,在硬盘有足够空闲时长时,使之关闭以减少能耗.针对大容量缓存,我们采用了合适的树形搜索结构,提出...

| Abstract: | Compared with traditional hard disk drives(HDDs),solid-state drives(SSDs) are shock-resistant and quieter,and have lower power consumption,lower access time and latency while HDDs have much higher capacity and are cheaper than SSDs.To have the merits of both sides while avoiding their disadvantages,we propose a hetero-drive to combine SSD and HDD by using SSD as a cache for HDD,which creates more idle time for HDD to shut-down for power-saving.At the same time,we put forth a decay-enforcement replacement al... |
