🔗 Redis on NVMe SSD by Zvika Guz, Samsung

"In this talk we report on our experience with Redis-on-Flash (RoF)—a recently introduced product that uses SSDs as a RAM extension to dramatically increase the effective dataset capacity that can be stored on a single server. This talk provides the first in-depth RoF system performance characterization: we consider different use cases (varying both RAM-to-disk access ratio and object size), and compare SATA-based RoF, NVMe-based RoF, and all-RAM Redis deployments. We show that the superior performance of NVMe drives in terms of both latency and pea bandwidth makes them a particularly good fit for RoF use cases. Specifically, we show that backing RoF with NVMe drivescan deliver more than 2 million operations per second with sub-millisecond latency on a single server."
