Broadcom Inc. announced the availability of the industry's first open end-to-end networking solution optimized for remote direct memory access (RDMA) over converged Ethernet. Hyperscale operators and enterprise data centers can now deploy fully optimized systems connected by Broadcom, using open standard RDMA.
Jointly integrated by Broadcom and Arista, this end-to-end solution features Broadcom's Ethernet NIC and switching technology. Broadcom and Arista's RoCE solution simplifies RoCE deployment in the data center by using an open, end-to-end congestion control algorithm to deliver the industry's lowest latency at scale.

Optimization of the entire structure, covering NIC and switches, contributes to scale and performance improvements over solutions that rely exclusively on the NIC to manage network behavior. Tests carried out by both companies demonstrate improvements in congestion control latency over existing solutions, improved bandwidth and collective completion times.
Additionally, Broadcom and Arista collaborated to provide comprehensive documentation to simplify RoCE deployment and management and increase data center performance.
“Knowing and delivering what the market needs is fundamental for Arista. High-performance RoCE networking is critical for our customers across a wide range of verticals, such as cloud, machine learning, AI, storage, and HPC. Our mission to deliver scalable, market-leading Ethernet networking solutions to expand the RDMA ecosystem and simplify deployments is essential for our customers,” said Narayanan Surynarayanan, director of systems engineering at Arista. “By combining the Broadcom NIC with Arista switches, customers get complete, performance-optimized, turnkey solutions for RoCE networks.”
“RDMA has become a must-have technology in the data center for NICs and Ethernet switches. Broadcom has been working diligently with networking industry leader Arista to expand the hardware ecosystem,” added Jas Tremblay, vice president and general manager of Broadcom's Data Center Solutions Group. “This long-standing collaboration marks a critical turning point for the networking industry, making RoCE a competitive, multi-vendor technology that will benefit a wide range of customers and applications. We are deeply committed to developing open RDMA standards for low-latency, high-speed data transfers, and working with Arista ensures we deliver the best technology to customers, the right way.”
