At IBTA, we are pleased to announce the launch of the RoCE Initiative, a new effort to highlight the many benefits of RDMA over Converged Ethernet (RoCE) and to facilitate the technology’s adoption in the enterprise data centers. With the rise of server virtualization and big data analytics, data center architects are demanding innovative ways to improve overall network performance and to accelerate applications without breaking the bank in the process.
Remote Direct Memory Access (RDMA) is well known in the InfiniBand community as a proven technology that boosts data center efficiency and performance by allowing the transport of data from storage to server with less CPU overhead. RDMA technology achieves faster speeds and lower latency by offloading data movement from the CPU, resulting in more efficient execution of applications and data transfers.
Before RoCE, the advantages of RDMA were only available over InfiniBand fabrics. This left system engineers that leverage Ethernet infrastructure with only the most expensive options for increasing system performance (i.e. adding more servers or buying faster CPUs). Now, data center architects can upgrade their application performance while leveraging existing infrastructure. There is already tremendous ecosystem support for RoCE; it is supported by server and storage OEMs, adapter and switch vendors, and all major operating systems.
Through a new online resource, the RoCE Initiative will:
- Enable CIOs, enterprise data center architects and solutions engineers to learn about improved application performance and data center productivity through training webinars, whitepapers and educational programs
- Encourage the adoption and development of RoCE applications with case studies and solution briefs
- Continue the development of specifications, benchmarking performance improvements and technical resources for current/future RoCE adopters

High performance computing has been integral to solving large-scale problems across many industries, including science, engineering and business. Some of the most interesting use cases have come out of NASA, where supercomputing is essential to conduct accurate simulations and models for a variety of missions.
NASA’s flagship supercomputer, Pleiades, is among the world’s most powerful, currently ranking seventh in the United States and eleventh globally. It is housed at the NASA Advanced Supercomputing (NAS) facility in California and supports the agency’s work in aeronautics, Earth and space science and the future of space travel. At the heart of the system is InfiniBand technology, including DDR, QDR and FDR adapters and cabling.
The incremental expansion of Pleiades’ computing performance has been fundamental to its lasting success. Typically, a computer cluster is fully built from the onset and rarely expanded or upgraded during its lifetime. Built in 2008, Pleiades initially consisted of 64 server racks achieving 393 teraflops with a maximum link speed of 20Gb/s. Today, the supercomputer boasts 160 racks with a theoretical peak performance of 5.35 petaflops, or 5,350 teraflops, and a maximum link speed of 56Gb/s.
To further demonstrate the power of the InfiniBand-based Pleiades supercomputer, here are several fun facts to consider:
- Today’s Pleiades supercomputer delivers more than 25 million times the computational power of the first Cray X-MP supercomputer at the NAS facility in 1984.
- The number of days it would take every person in the world to complete one minute of Pleiades’ calculations if they each performed one calculation per second, eight hours per day: 1,592.
- The NAS facility has the largest InfiniBand network in the world, with over 65 miles (104.6 km) of cable interconnecting its supercomputing systems and storage devices-the same distance it would take to stretch to from the Earth’s surface to the part of the thermosphere where auroras are formed.
