| Abstract: | Solid state disk wins its edge over hard disk in storage systems,for it provides better random I/O performance.In this paper,the different I/O characteristics of HDD,Flash-based SSD and DRAM-based SSD are investigated respectively.And then the related research of storage acceleration with SSD is introduced.After that,the architecture of accelerated Lustre-oriented storage system with SSD is presented and the modules and object migration policy of it are designed. |
