Optimizing NVMe-oF Comparing Performance of Different Transports with Host Factors using Synthetic & Real-World Workloads

NVMe-oF performance is compared using RDMA (iWARP & RoCEv2) and TCP transports across 100GbE. Synthetic and real-world workloads are applied across different Fabrics to a storage target using both standard (1500B) and jumbo (9000B) MTU frames. Performance is compared between a 6-SSD 3D XPointLUN and a 6-SSD 3D NAND LUN. Results show the impact of different workloads (synthetic corner case and real-world workloads), RDMA and TCP transport mechanisms (CPU onload vs. CPU offload) and different types of storage LUNs (3D XPoint vs. 3D NAND).
