Bridging the Gap Between NVMe SSD Performance and Scale Out Software | SNIA

Abstract

NVMe SSDs are becoming increasingly popular choice in scale out storage for latency sensitive workloads like databases, real time analytics, video streaming. NVMe SSDs provide significant performance throughput and lower latency compared to SATA, SAS SSDs. It is not unrealistic to expect these devices providing close to million random IOs per second. However scale out software stacks have significant amount of software overhead limiting the immense potential of NVMe SSDs. In this session, we present all flash scale out cluster performance, analysis on data path I/O overhead and programming techniques to systemically address software performance barriers. Learning Objectives Scale out storage software data path flows Performance profiling with NVMe SSDs User mode v/s kernel mode NVMe SSD integration Optimization techniques
