NVMe over Fabric in a Nutshell
NVMe –based devices are gaining increased popularity in datacenters. However, once Shared Storage becomes an indispensable part of a data storage solution we are facing various technical issues. One of them is the bottleneck of obsolete SAN protocols.
The 4.8 kernel has included support of NVMe over RDMA. In this presentation, I’ll elaborate on the essence of this technology and describe options of SAN configuration based on the new approach.
I’ll unveil the results of testing NVMe over RDMA performance with other protocols using remote direct access to memory (iSER, SRP, SMB Direct) in a cluster with overall bandwidth above 4 TB/s.
Last but not least, I’ll share a few insights into optimal methodology of testing data storage systems based on Flash (SNIA SSS PTS), and the impact of NUMA on performance.
