These adapters 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.
This product guide describes the QLogic QLE2740 Series HBAs for Lenovo servers and provides essential pre-sales information to understand the products, their key features and specifications, and compatibility. This guide is intended for technical specialists, sales specialists, sales engineers, and IT architects who want to learn more about the adapters and consider their use in IT solutions.

Introduction
The QLogic QLE2740 Series 32 Gb Fibre Channel (FC) Host Bus Adapters (HBAs) are Generation 6 (Gen 6) FC adapters for Lenovo ThinkSystem servers. These adapters 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.
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.
The QLogic QLE2742 2-port 32 Gb Fibre Channel HBA is shown in the following figure.

Key features
The QLogic QLE2740 Series 32Gb Fibre Channel HBAs have the following features:
- 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 for NVMe over Fibre Channel (FC-NVMe). The adapters support low-latency access to scale out NVMe with full support for the FC-NVMe protocol. The adapters can simultaneously support FC-NVMe and FCP-SCSI storage traffic on the same physical port, enabling customers to migrate to NVMe at their own pace.
- 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.
- Read diagnostic parameters (RDP) feature provides detailed port, media, and optics diagnostics to easily discover and diagnose link-related errors and degrading conditions on any N_Port-to-F_Port link.
- Link cable beacon (LCB) enables administrators to visually identify both ends of a physical link by flashing HBA's LEDs, simplifying identification of the connection peers within server racks without tracing the cable.
- Single-pane-of-glass management across generations of QLogic FC adapters with QLogic QConvergeConsole (QCC).
- Deployment flexibility and integration with third-party management tools, including the VMware vCenter and Brocade Network Advisor.
- Support for 32 Gb, 16 Gb and 8 Gb FC devices.
- Comprehensive virtualization capabilities with support for N_Port ID Virtualization (NPIV).
- A common driver model allows a single driver to support all QLogic HBAs on a given OS.
- Reduce the number of cards, cables, and PCIe slots required.
- Exceptional performance per watt and price/performance ratios.
- Backward compatibility with existing 8Gb FC and 16Gb FC infrastructure, leveraging existing SAN investments.
- Allow application of SAN best practices, tools, and processes with virtual server deployments.
- Ensure data availability and data integrity.
- Boot from SAN capability reduces the system management costs and increases uptime.
The following table compares features of QLogic FC adapters available for ThinkSystem servers.
