IBTA Announces RoCE Specification, Bringing the Power of the RDMA I/O Architecture to Ethernet-Based Business Solutions
As you may have already heard, earlier this week at HPC Financial Markets in New York, the IBTA officially announced the release of RDMA over Converged Ethernet - i.e. RoCE. The new specification, pronounced “Rocky,” provides the best of both worlds: InfiniBand efficiency and Ethernet ubiquity.
RoCE utilizes Remote Direct Memory Access (RDMA) to enable ultra low latency communication - 1/10th that of other standards-based solutions. The low latency is enabled by the use of RDMA which moves data from one node to another without requiring a lot of help from the CPU or operating system. The specification applies to 10GigE, 40GigE or higher speed adapters.
For people locked into an Ethernet infrastructure who are not currently using RDMA but would like to, RoCE lowers the barriers to deployment. In addition to low latency, RoCE end user benefits include improved application performance, efficiency, and cost and power savings.
RoCE delivers compelling benefits to high-growth markets and applications, including financial services, data warehousing and clustered cloud computing. Products based on RoCE will be available over the coming year.
