InfiniHost III Ex MHEA28-1TC 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.

InfiniBand HCA Application Support
The InfiniBand architecture defines and supports many applications, most with remote direct memory access (RDMA) capabilities. This dexterity enables high performance clustering, communication and storage traffic to be run over an InfiniBand fabric. These HCA cards have hardware support for the following protocols: MPI (for HPC clusters), DAT (for databases), SDP (for legacy applications), IPoIB (Internet Protocol over InfiniBand), NFS over RDMA (for network attached storage), SRP (for block storage), and many embedded applications like video streaming, aerospace, military, and electronic controls.
