InfiniHost III Lx Single-Port 10 or 20Gb/s InfiniBand Adapter

Overview

The InfiniHost III Lx is a single-port 4X InfiniBand adapter silicon device that enables the expansion of PCI Express infrastructure in data center and high-performance computing environments. The 4X InfiniBand port on the InfiniHost III Lx supports either 10Gb/s (SDR version) or 20Gb/s (DDR version). The InfiniBand port 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 an optimal, cost-effective solution for high-performance server and storage clustering.
