A Flash-based Hybrid Storage Simulation System
Chen Cha · Jisuanji gongcheng · 2015
Flash memory is developing very rapidly in recent years. It becomes a new non-volatile storage storage product with large capacity,high performance,low pow er consumption,and can effectively make up for the performance gap of memory and disk to improve the storage system. Based on it,this paper designs and implements a flash-based hybrid storage simulation system called Hybrid Arch. It supports file splitling distribution,and the file-interface accessing by increasing the file distribution layer,and implements some typical architectures of hybrid storage,including Tw o Layers( TL),Pure Flash( PF),Flash-as-Part-of-Disks( FPD),Tow er( TO),and Horizontal Cache( HC). And then a series of evaluation experiments are made based on Hybrid Arch to compare and analyze the performance and flash w rite amounts for different architectures. The results indicate the Horizontal Cache( HC) architecture makes a good balance among performance,cost-efficiency,and lifetime.
