AXX10GBTWLIOM3 Intel X540-BT2 10G RJ45 PCIe 2.1 x5 Ethernet Network Card

Enterprise Mezzanine 10GbE Copper Network Adapter featuring Intel X540-BT2 controller with the AXX10GBTWLIOM3

The AXX10GBTWLIOM3 is a server mezzanine NIC designed to extend in-chassis network bandwidth using dual-port 10GBASE-T RJ45 connectivity, optimized for environments that require copper uplinks with auto-negotiation across 100M/1G/10G profiles. Built on the Intel Ethernet Controller X540 Series X540-BT2, it targets predictable throughput and operational consistency in virtualized and converged server deployments without relying on RDMA or DPU-based offload.

Through a PCIe 2.1 mezzanine host interface with a single connector and x5 electrical specification, the AXX10GBTWLIOM3 integrates cleanly into supported server platforms while preserving primary PCIe slots for accelerators or storage HBAs. The adapter’s virtualization-oriented architecture supports Intel VT-c capabilities including SR-IOV and VMDq, enabling lower-latency I/O paths, improved queue management, and better tenant isolation for VM-dense clusters. This makes AXX10GBTWLIOM3 a practical choice for scaling east-west traffic, management networks, and copper-based top-of-rack connectivity where RJ45 operational continuity is required.

Why Choose the AXX10GBTWLIOM3?

The AXX10GBTWLIOM3 delivers a balanced density-to-performance profile by adding 2 ports of 10GbE via a mezzanine form factor, reducing cabling changes while aligning with existing 10GBASE-T copper infrastructures. For enterprise IT, the AXX10GBTWLIOM3 supports scalable virtualization I/O with SR-IOV and VMDq, improving consolidation efficiency and maintaining deterministic network behavior across mixed-speed access layers.

Intel engineering emphasizes controller-level stability, broad platform compatibility, and predictable driver behavior across enterprise operating systems and hypervisors. With the AXX10GBTWLIOM3, this translates into a standards-aligned NIC design that fits modern data center lifecycle requirements for qualification, repeatable deployment, and sustained availability.

Key Applications:

• Server virtualization and multi-tenant VM networks
• Hypervisor host uplinks and management networks
• Legacy copper 10GbE top-of-rack connectivity
• Enterprise application and database server networking
• Private cloud and clustered compute nodes
