InfiniHost III Ex Dual-Port 10 or 20Gb/s InfiniBand Adapter
Overview
The InfiniHost III Ex is a dual-port 4X InfiniBand adapter silicon device that enables the expansion of PCI Express infrastructure in data center and high performance computing environments. The dual 4X InfiniBand ports on the InfiniHost III Ex supports either 10Gb/s (SDR version) or 20Gb/s (DDR version) per port. Each InfiniBand interface features four integrated 2.5Gb/s (SDR version) or 5Gb/s (DDR version) SerDes interfaces, eliminating the requirement for external physical layer devices. By providing world-class latency and high-bandwidth connectivity over a PCI Express x8 interface, the devices provide the optimal solution for high-performance server and storage clustering.
