N2 - Emerging Non-Volatile Memory (NVM) technologies are promised to revolutionize storage systems by providing fast, persist data accesses on memory bus. However, the limited capacity of NVM devices calls for multi-layer storage topology that is able to combine fast, expensive NVM with slower, cheaper block devices to harness the characteristics of both technologies. This paper proposes an efficient file system named NBFS for hybrid in-memory NVM and block devices. NBFS can distribute the data pages of a single file to multiple memory nodes in NUMA architecture and multiple block devices. To take full advantages of NVM, NBFS provides a mechanism to migrate file data between NVM and block devices according to the data access features. Besides, we design a resource pool for block devices to minimize additional storage and performance overhead. Experimental results show that in write-intensive workloads, our design performs well and has a high bandwidth.
