Flor - An Open High Performance RDMA Framework Over Heterogeneous RNICs

Explore a 15-minute conference talk from OSDI '23 that introduces Flor, an innovative open framework designed to address the challenges of heterogeneous RDMA-capable NICs (RNICs) in datacenter applications. Discover how Flor provides a flexible control plane in software and a unified hardware plane to improve cooperation between RNICs from different vendors and generations. Learn about the framework's implementation across various RNIC models, including Intel E180, Mellanox CX-4 and CX-5, and Broadcom RNICs. Gain insights into Flor's performance in scenarios such as packet loss, incast, and large-scale cross-pod communication, and understand how it mitigates performance gaps between different RNIC models without relying on PFC.
