Broadcom and Arista offer industry's first open, end-to-end RDMA networking solution

Broadcom Inc. has announced the availability of the industry’s first open end-to-end networking solution optimized for Remote Direct Memory Access (RDMA) over Converged Ethernet. Hyperscaler and enterprise data-center operators can now deploy fully optimized systems that are connected by Broadcom, using open-standard RDMA.

Jointly integrated by Broadcom and Arista, this end-to-end solution features Broadcom’s Ethernet NIC and switch technology. The Broadcom and Arista RoCE solution simplifies the deployment of RoCE in the data center, by using an end-to-end open congestion control algorithm to deliver the industry’s lowest latency at scale.

The whole-fabric optimization, covering NIC and switches, contributes to scale and performance improvements over solutions that rely exclusively on the NIC to manage network behavior. Tests conducted by both companies demonstrate improvement in congestion control latency over existing solutions, improved bandwidth, and collective completion times.

In addition, Broadcom and Arista have collaborated to provide comprehensive documentation to simplify RoCE deployment, management, and increase performance in the data center.

“Knowing and delivering what the market needs is critical to Arista. High-performance RoCE networking is key to our customers in a wide range of verticals such as the cloud, machine learning, AI, storage, and HPC. Our mission to offer market-leading, scalable, Ethernet networking solutions to expand the RDMA ecosystem and simplify deployments is essential for our customers,” said Narayanan Surynarayanan, director, systems engineering, Arista. “By combining Broadcom’s NIC with Arista switches, customers get turnkey, performance-optimized, end-to-end solutions for RoCE networking.”

“RDMA has become a must-have technology in the data center for Ethernet NIC and switches. Broadcom has been diligently working with Arista, a networking industry leader, to expand the hardware ecosystem,” added Jas Tremblay, VP and GM of the Data Center Solutions Group at Broadcom. “This long-standing collaboration marks a critical turning point for the networking industry by making RoCE a multi-vendor, competitive technology that will benefit a broad range of customers and applications. We are deeply committed to developing open standards RDMA for low-latency, high-speed data transfers, and working with Arista ensures we deliver the best technology to customers, the right way.”
