Today the IBTA announced remote direct memory access over converged Ethernet (RoCE, pronounced “rocky”) for both 10 and 40 GbE

RoCE, built on a foundation of the highly efficient use of computing resources, brings significant benefits to end users. By reducing the number of servers needed, eliminating cabling and improving application performance, RoCE can produce energy savings and reduce the footprint of Ethernet-based data centers. Its unique “one fat pipe” approach to server I/O gives the user great flexibility in deploying applications and is an excellent complement to virtualization strategies being deployed today. By attacking latency, RoCE increases performance in search, database, financial and high transaction rate applications.

…RoCE is implemented in and downloadable today in the OpenFabrics Enterprise Distribution (OFED) 1.5.1. Many Linux distributions, which include OFED, support a wide and rich range of middleware and application solutions such as IPC, sockets, messaging, virtualization, SAN, NAS, file systems and databases. RoCE can therefore deliver all three dimensions of unified networking on Ethernet – IPC, NAS and SAN.
