QLogic’s line of SDR and DDR host channel adapters (HCAs) come in single or dual port configurations, with or without memory, and support PCI-X or PCI-Express environments.

When installed in standard servers, blade servers, storage and communications platforms, the QLogic 7000 PCI-X and 9000 PCI-Express HCAs create a high-performance channel between the host device and the InfiniBand fabric. Information transfer is at 10 Gb/s SDR or 20 Gb/s DDR—up to 20 times the bandwidth and 10% the internal latency of traditional Gigabit Ethernet server interfaces.

A comprehensive suite of host Upper Level Protocols (ULPs) is available and contained within the QuickSilver Fabric Software Suite. These include Scali MPI, Virtual Ethernet NIC, SRP, IPoIB, SDP, uDAPL, and RDS.
