QLogic QLE2740-SR-CK High Performance Fiber Channel HBA

product overview

QLE2740-SR-CK is a high-performance 16Gb Fibre Channel (16GFC) host bus adapter designed specifically for enterprise storage area networks (SANs). It features PCIe 3.0 interfaces and short wave (SR) SFP+optical modules, providing low latency, high reliability storage connectivity for critical business applications, suitable for virtualization, database, and high-performance storage environments.

core features

High speed fiber channel support

Supports 16GFC (compatible with 8GFC/4GFC/2GFC), automatically negotiates speed, seamlessly integrates with existing SAN architecture.

SR SFP+optical module interface (850nm wavelength), multi-mode fiber transmission distance up to 100 meters (OM4 fiber).

Excellent performance and low latency

PCIe 3.0 x8 interface provides up to 8GT/s bandwidth to meet high throughput requirements.

Hardware acceleration function: Supports FCP (Fiber Channel Protocol) offloading to reduce CPU overhead.

Enterprise level reliability and scalability
