The document discusses the convergence of Ethernet and InfiniBand networks for high-performance computing (HPC). Enhancements to Ethernet, including speeds of 40GbE and 100GbE, have closed the performance gap with InfiniBand. While InfiniBand currently dominates HPC networks, the enhancements to Ethernet and organizations' desire to leverage existing Ethernet infrastructure will result in Ethernet becoming the standard for most HPC applications over the next few years, with InfiniBand remaining only for niche uses. Annual revenue from Ethernet is expected to surpass InfiniBand by 2016.
