InfiniHost III Ex dual-port 4X InfiniBand Host Channel Adapter (HCA) cards connect to the host system through a PCI Express x8 interface. Single data rate (SDR) InfiniHost III Ex cards support dual 10Gb/s InfiniBand connections while double data rate (DDR) versions support dual 20Gb/s InfiniBand connections. InfiniHost III Ex HCA cards deliver the most cost effective 10 or 20Gb/s solution available and feature remote direct memory access (RDMA), hardware transport, and advanced per queue pair (QP) QoS services. All InfiniHost III Ex cards can be directly inserted into PCI Express x8 or wider slots of standard servers, blade servers, storage and communications platforms to enable InfiniBand fabrics. All adapter cards utilize 4X MicroGigaCN InfiniBand compliant connectors for copper cables. This copper connector provides the lowest cost 10 or 20Gb/s connection available. In addition, a pluggable media adapter module can be used for fiber connections up tp 300m. Feature Highlights Enabled by the high-bandwidth and low-latency capability of PCI Express, the MHEA28-XT and MHGA28-XT cards feature MemFree technology. This removes the requirement for local memory on the PCI Express adapter card itself, and instead, uses system memory to store connection information resulting in lower power, lower adapter card cost, and smaller physical size. InfiniHost III Ex HCA cards feature a full hardware implementation of the InfiniBand architecture memory protection and translation tables, as well as hardware transport. This drastically reduces processing overhead and allows the host CPU to spend its cycles on processing applications rather than network transport tasks. Software Support All InfiniHost III Ex low profile HCA cards include verbs interface and device drivers for both Windows and Linux operating systems. In addition, the cards include internal Subnet Management Agent (SMA) and General Service Agents, eliminating the requirement for an external management agent CPU. The HCAs are fully compatible with the open source software suite. Mellanox also provides InfiniBand Gold, an easy-to-install, open-source software package including device drivers, upper layer protocols and management tools. In addition to Linux and Windows, industry support for virtually all other operating systems is available including HPUX, AIX, OS-X, Solaris, and VxWorks.
