HPE MCX631102 NIC 10/25GB 2-port

Network interface card delivering dual 25GbE ports over PCIe 4.0 x8, engineered for high-throughput data center and enterprise workloads. The HPE MCX631102 leverages the NVIDIA Mellanox ConnectX-6 Dx controller to accelerate software-defined networking, storage, and virtualization with line-rate performance and advanced offloads.

Advantages

This adapter doubles bandwidth per port compared to 10GbE while maintaining backward compatibility with 10GbE infrastructure. Hardware offloads for RoCE, NVMe-oF, VXLAN, NVGRE, and GENEVE reduce CPU overhead, freeing processor cycles for applications. SR-IOV enables efficient sharing of the adapter across multiple virtual machines, while DPDK and OVS support boost packet processing for NFV and SDN deployments. Energy Efficient Ethernet and a typical power draw of just 12.5 W keep operational costs low.

Suitable for

• HPE ProLiant Gen10 Plus servers requiring high-speed network connectivity
• Virtualized environments using VMware ESXi, Microsoft Hyper-V, or KVM
• Software-defined storage (SDS) and hyperconverged infrastructure (HCI)
• Database clusters and transactional systems demanding low latency
• Cloud-native and containerized workloads with Kubernetes or OpenShift

Key specifications

• Dual SFP28 ports supporting 25GbE and 10GbE speeds
• PCIe 4.0 x8 host interface for full-duplex bandwidth
• NVIDIA Mellanox ConnectX-6 Dx controller with advanced offloads
• RDMA over Converged Ethernet (RoCE) and NVMe over Fabrics (NVMe-oF)
• SR-IOV, VXLAN, NVGRE, GENEVE, DPDK, and OVS support
• Jumbo frame and PXE boot support; NC-SI management interface
• Low-profile and full-height brackets included
• Compatible with Windows Server, RHEL, SLES, VMware ESXi, Ubuntu, CentOS

Recommendations

For organizations standardizing on HPE ProLiant Gen10 Plus servers, this adapter is the natural choice to unlock 25GbE performance while preserving investment in existing 10GbE optics. Its rich offload and virtualization feature set makes it ideal for dense, software-defined data centers. Verify SFP28 transceiver compatibility and ensure adequate PCIe cooling for sustained throughput.
