An update to the &os; RDMA stack based on code from Linux + v4.9 was merged into &os; 12-CURRENT on November 4th, + including many bug fixes and new features with a focus on + RoCEv2 — Routable RoCE.

+ +

RDMA over Converged Ethernet (RoCE) is a network protocol + that leverages Remote Direct Memory Access (RDMA) capabilities + to accelerate communications between applications hosted on + clusters of servers and storage arrays. RoCE incorporates the + IBTA RDMA semantics to allow devices to perform direct memory + to memory transfers at the application level without involving + the host CPU. Both the transport processing and the memory + translation and placement are performed by hardware resulting + in lower latency, higher throughput, and better performance + compared to software based protocols.

+ +

RoCEv2 is the most recent version of RoCE, adding some routing + capabilities as both IP and UDP headers are included in the + packet format. To complete the RoCEv2 solution, Support for + ECN (Explicit Congestion Notification, lossy fabric) and PFC + (Priority Flow Control, lossless fabric) protocols with rate + limiting options will be added in the first quarter of + 2018.

+ +

This project also introduces the following updates:
