Event details
Within the session, it mentions NVMe over Fabrics (NVMe-oF), which I believe typically refers to RDMA (TCP/ROCE vs UDP/iWARP). However, NVMe over TCP is relatively new, and I've heard that some other platforms also support it. It would be great if you could elaborate on this.
Hear you Cem. But RDMA is something planned for Microsoft NVMe over Fabric, as stated in the video snipped linked above. NVMe-OF with or without RDMA (cherry on top when ready) it will leverage TCP. Whether it will use UDP (IWARP) at all wasn't said. I personally doubt it due to the constraints of NIC hardware still supporting iWARP today. Mind UDP is not generally faster than TCP. Speaking about S2D Microsoft currently favours RoCEv2 with Mellanox Cx5/Cx6 being one of the best NICs available (from my experience).
