SMUGDESK QL41232HLCU-LN 10/25G SFP28 PCIe 3.0 x8 network card

SKU CH-XGRK-ZK3P1

Dual-port 10/25G SFP28 NIC with PCIe 3.0 x8, RDMA offload and virtualization acceleration for storage and cloud clusters

  • Dual 10/25G SFP28 ports for flexible copper or fibre cabling
  • PCIe 3.0 x8 interface with full-height and low-profile brackets included
  • Marvell QL41232 controller with RoCEv2 and iWARP RDMA offload for NVMe-oF
  • SR-IOV, VXLAN offload and DPDK support reduce CPU load in virtualization
  • OEM Lenovo part 01KR589 with driver support for Windows Server, Linux and VMware ESXi

Dual-Port 10/25G SFP28 Server NIC

This dual-port network card fits into a PCIe 3.0 x8 slot and delivers 10 GbE or 25 GbE connectivity through SFP28 cages. It targets server administrators upgrading storage clusters, cloud nodes or IDC racks where RDMA offload and hardware virtualization features reduce CPU overhead. The passive heatsink and included low-profile bracket suit dense 1U and 2U chassis.

Replaces legacy 10G single-port adapters

Moving from a single 10G port to dual 25G ports doubles available bandwidth per slot and enables NVMe-oF traffic to bypass the kernel via RoCEv2 or iWARP. The jump is worth it when storage latency targets demand RDMA and when SR-IOV or VXLAN offload can consolidate multiple virtual functions onto one physical interface. Older 10G DAC cables can be reused at the lower speed.

Simple drop-in for most rack servers

The card ships with both full-height and low-profile brackets so it installs in standard or shallow chassis without extra parts. SFP28 modules or DACs latch securely; the main installation issue is forgetting to enable SR-IOV or RDMA in the server BIOS and OS driver stack, which leaves the advanced offload engines inactive. Driver packages are available for Windows Server, Linux and VMware ESXi.

Questions about this item

Does the QL41232HLCU-LN card fit a low-profile server bracket?

The card ships with dual full-height and low-profile brackets so it installs in either standard or low-profile rack servers.

What is the PCIe slot requirement for the QL41232HLCU-LN?

Insert the card into a PCIe 3.0 x8 or wider slot; the edge connector is keyed for x8 electrical width.

Are the SFP28 transceivers on the QL41232HLCU-LN replaceable?

The SFP28 ports accept standard hot-pluggable modules, so you can swap 10G or 25G DAC, AOC or fibre transceivers without removing the card.
