About RoCE

What is RoCE?

Remote Direct Memory Access (RDMA) is a critical technology at the heart of the fastest supercomputers and many of the largest data centers in the world. RDMA first became widely adopted in the Supercomputing space with InfiniBand but has expanded into enterprise markets and is now being widely adopted over Ethernet networks with RDMA over Converged Ethernet or RoCE (pronounced like “rocky”). RoCE is driving an advanced data center architecture that eliminates dedicated storage area networks and converges compute, networking and storage onto a single fabric. Leveraging the latest advances in reliable Ethernet and Data Center Bridging (DCB), efficient RDMA mechanisms in RoCE provide lower CPU overhead and increase mainstream data center application performance over Layer 2 and Layer 3 fabrics at 10, 40, and 100 Gigabit Ethernet speeds and beyond.
