Quad-port Enhanced 16GFC Fibre Channel Adapters SFP+ QLE2694 Network Card

QLogic QLE2694-SR Product Overview

QLE2694-SR is a high-performance 16Gb fiber channel (16GFC) dual port HBA launched by QLogic (now under Cavium/Marvell), designed specifically for enterprise storage area networks (SANs), suitable for applications that require high bandwidth and low latency, such as virtualized environments, data storage, and critical business data centers.

Key Features

High performance interface

16Gb Fiber Channel (16GFC): Each port supports up to 1600 MB/s full duplex bandwidth, compatible with 8Gb/4Gb/2Gb rates, ensuring backward compatibility with older devices.

Dual port design: A single card provides two independent ports, supporting redundancy and load balancing.

Low latency and high reliability

Adopting PCIe 3.0 x8 host interface, providing sufficient bandwidth to avoid bottlenecks.

Hardware acceleration functions (such as T10-DIF data integrity verification) ensure the integrity of data during transmission.

Virtualization optimization

Support NPIV (N_Port ID Virtualization), allowing multiple virtual ports to be assigned to a single physical port, suitable for virtual server environments such as VMware, Hyper-V, KVM.

Compatible with mainstream hypervisors and operating systems, including Windows, Linux, Solaris, etc.

Advanced management functions

Support QLogic SANbox management tool, providing remote monitoring, diagnosis, and firmware updates.

Integrate Boot from SAN functionality to simplify deployment of diskless servers.

Energy saving design

Compliant with RoHS standards and supports low-power modes (such as dynamic link throttling).
