The QLogic 32 Gb Fibre Channel (FC) 1-port and 2-port Host Bus Adapters (HBAs) are Generation 6 (Gen 6) FC adapters for Lenovo ThinkSystem servers. These adapters are based on Cavium technology and offer industry leading native FC performance with extremely low CPU usage with full hardware offloads. With performance of up to 1.3 million I/O operations per second (IOPS), these adapters can be used to support all-flash arrays (AFAs) -- Fibre Channel storage systems comprised completely of high-speed solid-state drives.<br><br>Powerful management tools automate and simplify SAN provisioning to help reduce cost and complexity, while the unmatched 32 Gbps performance eliminates potential I/O bottlenecks in today’s powerful multiprocessor, multicore servers.

• Maximum performance with up to 650K input/output operations per second (IOPS) per port (1.3 million IOPS in a dual-port adapter) to support larger server virtualization deployments and scalable cloud initiatives, and performance to match new multicore processors, SSDs/flash storage, and faster server host bus architectures
• Independent function, transmit and receive buffers, an on-chip CPU, DMA channels, and a firmware image for each port enable complete port-level isolation, prevent errors and firmware crashes from propagating across all ports, and provide predictable and scalable performance across all ports
• Support forward error correction (FEC) to enhance reliability of transmission and thereby performance
• Industry-standard class-specific control (CS_CTL)-based frame prioritization Quality of Service (QoS) helps alleviate network congestion by prioritizing traffic for time-sensitive mission critical workloads for optimized performance
• T10-PI data integrity with high performance offload provides end-to-end data corruption protection
• Support for Message Signaled Interrupts eXtended (MSI-X) improves host utilization and enhances application performance
• Fabric-assigned port worldwide name (FA-WWN) and fabric-based boot LUN discovery (F-BLD) pre-provisioning services allow servers to be quickly deployed, replaced, and moved across the SAN; the creation of zones, LUNs, and other services can be completed before the servers arrive on site
• Using the Brocade ClearLink diagnostic port (D_Port) available on the Brocade Gen 5 switches, administrators can quickly run automated diagnostic tests to assess the health of links and fabric components
