It offers an aggregate to 20 Gbps of full-duplex bandwidth.The QLogic HCA creates an expressway of balanced bandwidth betweenthe server and the IB fabric, allowing information transfer at 10 Gbps, upto 10 times the bandwidth of current server interfaces. A comprehensivehost environment of high-performance ULPs contained within the QLogicsoftware family enables the HCA to provide unprecedented performance tocore business applications that are supported by DataBase ManagementSystems (DBMS), clustering, HPBC, and high availability clustering.QLogic HCA in the Enterprise. Combined with its ULPs, the HCA is the channelby which today’s complex and costly enterprise environments quickly evolveto feed ever-growing processing requirements. Clustering, Ethernet, andFibre Channel are all concurrently supported via a single 10-Gb pipe. Thenet effect is a significantly reduced level of infrastructure complexity andimproved business responsiveness, with a lower total cost of ownership.The HCA, used in conjunction with QLogic’s family of InfiniBand clusteringswitches and virtual I/O systems, is part of a complete end-to-end InfiniBandsolution ready to enable today’s servers to handle tomorrow’s processingrequirements.Guaranteed Interoperability. InfiniBand ecosystem partner certifications,combined with agency and regulatory testing, ensures all products meetindustry compliance hardware and software specifications. All HCAs aretested extensively with third-party hardware, along with multiple softwareapplications, to ensure best-in-class InfiniBand interoperability andcompatibility. You can be confident purchasing QLogic HCAs to meet yourInfiniBand networking needs.Investment Protection. For over 15 years, QLogic has been a technologicalleader with products that address the current needs of customers, yetprovide strong investment protection to support emerging technologies andstandards. QLogic stands alone in the industry with its product portfoliodepth and experience in successfully delivering technological solutions thataddress the needs of today and tomorrow.
