QLogic Corp. QLE2694-SR 16Gb Quad Port FC PCIe Gen3 x16 network card

SKU CH-TPNC-2MKFK MPN QLE2694-SR

A 16 Gbps quad-port Fibre Channel HBA with a PCIe Gen3 x16 interface for high-throughput storage networks

  • Quad-port design expands SAN connectivity with four fibre-channel links
  • 16 Gbps per port delivers high-throughput storage traffic
  • PCIe Gen3 x16 interface maximises bandwidth and minimises latency
  • Backward-compatible speeds support 8 Gbps and 4 Gbps environments
  • Broad OS and server compatibility simplifies enterprise integration

Quad Port 16Gbps Fibre Channel HBA

The QLogic QLE2694-SR is a Fibre Channel host bus adapter with four ports, each running at up to 16Gbps. It connects through a PCI Express Gen3 x16 slot to deliver high-throughput storage networking. The card is built for enterprise SAN environments that require reliable, low-latency connectivity. Its quad-port design consolidates multiple links into a single expansion slot.

Suited for multi-port SAN hosts.

This adapter targets servers that need four independent Fibre Channel connections from one PCIe slot. It fits data-centre hosts attaching to redundant fabrics or scaling port density without consuming extra slots. Buyers needing only one or two ports should consider a dual-port or single-port HBA instead. The Gen3 x16 interface also requires a compatible motherboard or riser.

PCIe Gen3 x16 slot required for full performance

The card installs in a PCI Express Gen3 x16 slot to achieve its rated throughput. A smaller or slower slot will limit bandwidth and may prevent the adapter from operating correctly. Verify that the target server provides a physical x16 slot wired for Gen3 speeds before purchase. No other specification determines fit as decisively as the slot interface.

Questions sur cet article

Will the PCIe Gen3 x16 slot saturate before the four 16Gbps ports reach full speed?

The Gen3 x16 link provides enough bandwidth for all four ports at 16Gbps, so the bus will not be the first limit.

How much heat and noise should I expect when all four ports run continuously?

The card is passively cooled and designed for sustained enterprise workloads, so it runs silently within standard server airflow.

What cabling and transceivers do I need to connect the QLE2694-SR to my SAN?

Each port uses a short-wave SFP+ transceiver and OM3 or OM4 multimode fibre with LC connectors.
