Towards an Unwritten Contract of Intel Optane SSD
2019
USENIX Workshop on Hot Topics in Storage and File Systems
New non-volatile memory technologies offer unprecedented performance levels for persistent storage. However, to exploit their full potential, a deeper performance characterization of such devices is required. In this paper, we analyze a NVM-based block device -the Intel Optane SSD -and formalize an "unwritten contract" of the Optane SSD. We show that violating this contract can result in 11x worse read latency and limited throughput (only 20% of peak bandwidth) regardless of parallelism. We
