Paper Title: Highly scalable and performant All Flash CEPH Storage with NVMe-oF

Paper Abstract: It is well known that an all flash CEPH solution can provide a highly resilient shared storage environment that can also be high performance. When paired with NVMe-oF, the scaling options increase drastically while meeting and/or exceeding the expectations of resiliency or performance. NVMe-oF provides CEPH with the foundation of a truly independent scaling between compute nodes and storage. The use of Ethernet as the storage fabric means capacity scaling is limited only by an IP range, while RDMA over Converged Ethernet ensures the low latency and high performance. Composable Disaggregated Infrastructure enables device connectivity to be allocated in any way desired. This presentation will discuss the integration, configuration, final outcomes of the testing we have done to validate this solution.
