HP NVIDIA Mellanox ConnectX-6 LX Dual Port 25GbE SFP28 NIC 25GbE

The HP NVIDIA Mellanox ConnectX-6 LX Dual Port 25GbE SFP28 NIC provides two 25 Gigabit Ethernet ports in a compact expansion card designed for dense server and data center environments. With a physical layout of approximately 168mm x 122mm x 22mm and a lightweight construction, the card delivers increased network throughput, reduced latency and efficient packet handling for virtualization, storage and clustered compute workloads. The adapter supports SFP28 optics for 25GbE links and is intended for use in systems where balanced performance and space efficiency are important.

Advantages

The dual-port configuration enables redundant or aggregated 25GbE connectivity while maintaining a small footprint suitable for 1U and 2U servers. The card is engineered to provide low-latency packet processing and optimized throughput for high-performance computing, virtualization platforms and software-defined networking. Its compact dimensions and modest weight make installation straightforward in a wide range of server chassis.

Suitable for

• High-performance computing clusters and MPI workloads
• Virtualized server environments and hyper-converged infrastructure
• Network-attached storage and fast SAN interconnects
• Data center aggregation, leaf-spine architectures and top-of-rack switches

Key specifications

• Interface type: Dual SFP28 ports supporting 25GbE optics
• Form factor: Low-profile expansion card sized ~168mm x 122mm x 22mm
• Throughput: Up to 25 Gbps per port (aggregate 50 Gbps)
• Latency: Low-latency design optimized for HPC and storage traffic
• Compatibility: Designed for standard PCIe server slots (verify server compatibility before installation)
• Weight: Approximately 0.1395 kg

How to use

Install the NIC into an appropriate PCIe slot on a powered-down server following the server manufacturer's instructions. Insert compatible SFP28 transceivers or direct-attach cables into the SFP28 cages and connect to the network fabric. After powering the system, ensure the host operating system recognizes the adapter and install any vendor-provided drivers or firmware updates to enable full functionality and performance features. Configure link aggregation, VLANs or RDMA settings as required by your network design.

Recommendations

For optimal results use certified 25GbE SFP28 transceivers or DACs and keep firmware/drivers up to date. Verify airflow and clearance in dense server builds to maintain thermal performance. When deploying in clusters or storage networks, test link aggregation and RDMA settings in a staging environment before production rollout.
