InfiniBand (IB) 4X SDR to PCI Express Host Channel Adapter (HCA) 
An integral member of the QLogic family of interconnect offerings, the 7104-HCA-xxx series Single Data Rate (SDR) HCA is a single or dual port 4X IB HCA utilizing a x8 PCIe interface to enable higher server bandwidth than is possible with PCI-X. It offers an aggregate to 20 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 10 Gbps, up to 10 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.
 
 
QLogic HCA in the Enterprise
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 10-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.
 
 
Guaranteed Interoperability 
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 yourInfiniBand networking needs.
