Experiences with NVMe over Fabrics

In this video from the OpenFabrics Workshop, Parav Pandit from Mellanox presents: Experiences with NVMe over Fabrics.

“NVMe is an interface specification to access non-volatile storage media over PCIe buses. The interface enables software to interact with devices using multiple, asynchronous submission and completion queues, which reside in memory. Consequently, software may leverage the inherent parallelism and low latency of modern NMV devices with minimal overhead. Recently, the NMVe specification has been extended to support remote access over fabrics, such as RDMA and Fibre Channel. Using RDMA, NVMe over Fabrics (NVMe-oF) provides the high BW and low-latency characteristics of NVMe to remote devices. Moreover, these performance traits are delivered with negligible CPU overhead as the bulk of the data transfer is conducted by RDMA. In this session, we present an overview of NVMe-oF and its implementation in Linux. We point out the main design choices and evaluate NVMe-oF performance for both Infiniband and RoCE fabrics.”
