An integral member of the QLogic family of interconnect offerings, the 7104-HCA-xxx series Double Data Rate (DDR) HCA is a single or dual port 4X IB HCA utilizing a x8 PCIe interface to enable high server bandwidth. It offers an aggregate to 40 Gbps of full-duplex bandwidth.

The QLogic HCA creates an expressway of balanced bandwidth between the server and the IB fabric, allowing information transfer at 20 Gbps, up to 20 times the bandwidth of current server interfaces. A comprehensive host environment of high-performance ULPs contained within the QLogic software family enables the HCA to provide unprecedented performance to core business applications that are supported by DataBase Management Systems (DBMS), clustering, HPBC, and high availability clustering.
 

Combined with its ULPs, the HCA is the channel by which today’s complex and costly enterprise environments quickly evolve to feed ever-growing processing requirements. Clustering, Ethernet, and Fibre Channel are all concurrently supported via a single 20-Gb pipe. The net effect is a significantly reduced level of infrastructure complexity and improved business responsiveness, with a lower total cost of ownership.

The HCA, used in conjunction with QLogic’s family of InfiniBand clustering switches and virtual I/O systems, is part of a complete end-to-end InfiniBand solution ready to enable today’s servers to handle tomorrow’s processing requirements.
  

InfiniBand ecosystem partner certifications, combined with agency and regulatory testing, ensures all products meet industry compliance hardware and software specifications. All HCAs are tested extensively with third-party hardware, along with multiple software applications, to ensure best-in-class InfiniBand interoperability and compatibility. You can be confident purchasing QLogic HCAs to meet your InfiniBand networking needs.
