An Empirical Evaluation and Analysis of Performance of Multiple Optane SSDs

Abstract

Cloud Computing as a service-on-demand architecture has grown in importance over the previous few years. The storage subsystem in cloud computing has undergone enormous innovation in order to provide high-quality cloud services. Emerging non-volatile memory express (NVMe) technology has a considerable attraction in cloud computing by delivering high I/O performance in terms of latency and bandwidth. Especially, multiple NVMe SSDs can provide higher performance, fault tolerance, and storage capacity in the cloud computing environment. In this paper, we perform an empirical evaluation study of performance on recent NVMe SSDs (i.e., Intel Optane SSDs) with different RAID environments. We analyze the performance of the multiple NVMe SSDs with RAID in terms of different performance metrics via micro and macro benchmarks. We anticipate that the experimental results and performance analysis will provide the implications on various storage systems.
