1QL46AA HP X550-T2 10G RJ45 PCIe 3.0 x4 Ethernet Network Card

High-Performance Dual-Port 10GbE PCIe 3.0 Networking Adapter for Low-Latency Uplinks with the 1QL46AA

The 1QL46AA is an HP dual-port 10GbE PCIe NIC designed to deliver predictable bandwidth and low CPU overhead for modern server and workstation platforms. Built on the Intel X550-T2 controller, it targets enterprise uplinks where sustained throughput, stable latency, and driver maturity are critical for virtualization clusters and storage-connected compute.

Using a PCIe 3.0 x4 host interface, the 1QL46AA aligns with contemporary expansion topologies and preserves higher-lane slots for accelerators or NVMe. The dual 10GbE ports support resilient network designs such as active/active teaming, network segmentation, or dedicated paths for management and east-west traffic. For iSCSI and NAS client connectivity, the architecture enables high-throughput access to shared storage while maintaining headroom for VM traffic consolidation, helping reduce oversubscription at the rack level without reworking the core platform.

Why Choose the 1QL46AA?

The 1QL46AA provides a practical density-to-performance ratio by delivering 2x 10GbE from a single PCIe 3.0 x4 slot, simplifying port planning and switch uplink mapping in scale-out environments. It supports enterprise reliability expectations through a controller and platform integration approach optimized for consistent operation under sustained load, enabling straightforward rollouts across homogeneous server fleets.

HP designs adapters like the 1QL46AA to align with data centre operational standards, emphasizing validated interoperability, regulatory compliance, and predictable lifecycle behavior. This engineering focus helps reduce integration risk when standardizing network connectivity across mixed workloads and multi-generation compute nodes.

Key Applications:

• 10GbE server and workstation uplinks
