QLogic 16Gb FC Single-port and Dual-port HBA for IBM System x The QLogic 16 Gb FC Single-port and Dual-port Host Bus Adapters (HBAs) for IBM System x are sixth generation Fibre Channel Adapters. They offer 16 Gbps line-rate performance at extremely low CPU utilization with full hardware offloads. Support for powerful virtualization features make this adapter ideal for virtualized environments that need excellent input/output (I/O) performance to service growing numbers of virtual machines (VMs). Port architecture that offers independent functionality on each port -- independent CPU, isolated memory and independent firmware image -- provides higher reliability and predictable performance. Support for Message Signaled Interrupts eXtended (MSI-X) improves host utilization and enhances application performance. Support for 16 Gb, 8 Gb, and 4 Gb FC devices. Full hardware offload for Fibre Channel protocol. Support for PCIe 2.0 and PCIe 3.0 host interfaces.
