Green full-height PCIe network card with two SFP28 ports and a silver bracket

QLogic Corp.

QLogic Corp. QL41262HLCU-LN 25GbE SFP28 PCIe network card

SKU CH-M8HR-397AW

Dual-port 25GbE SFP28 PCIe x8 adapter with RDMA, FCoE and iSCSI offload

  • Dual-port 25 GbE throughput for high-bandwidth workloads
  • SFP28 connectivity enables flexible fibre or copper links
  • PCIe x8 interface delivers low-latency server integration
  • Hardware offload for iSCSI and FCoE reduces CPU overhead
  • RDMA support with iWARP and RoCE accelerates storage traffic

Dual-port 25GbE server adapter

The QLogic FastLinQ QL41262HLCU-LN is a full-height PCIe x8 network interface card built for servers that need dual 25 Gbps Ethernet links over SFP28 transceivers. It targets data-centre and high-performance computing environments where low-latency, high-throughput connectivity is required.

25 Gbps headroom and protocol offloads

Each of the two ports delivers up to 25 Gbps, providing ample bandwidth for storage replication, virtualisation traffic and clustered workloads. The adapter offloads RDMA over iWARP, RoCE and RoCE v2, plus FCoE, iSCSI and iSER, reducing CPU overhead when the link is saturated.

Full-height bracket with SFP28 cages

The full-height bracket fits standard server chassis and presents two SFP28 cages for direct-attach copper or optical modules. On-board support for SR-IOV and DCBX enables multi-tenant virtualisation and lossless Ethernet fabrics without additional configuration complexity.

Questions about this item

Will the dual-port 25GbE adapter fit in an older server that only has PCIe x8 slots?

The card uses a PCIe x8 edge connector, so it will seat and negotiate at x8 width in any compatible full-height slot.

How can I confirm both SFP28 ports are linked at 25 Gb/s after installation?

Check the adapter’s LED indicators or the OS network stack; each port should report a 25 Gb/s link speed when active transceivers are inserted.

Does the package include SFP28 transceivers or DAC cables, or must they be purchased separately?

The adapter ships without transceivers or cables; compatible SFP28 modules or direct-attach cables need to be sourced separately.
