Dual-Port 10Gbps Server Adapter

The Intel X520-SR2 is a high-profile PCI Express network adapter built for servers and workstations that require fast Ethernet connectivity. It provides two LC fibre ports operating at 10Gbps each, using 10GBase-SR transceivers for short-range multimode links. The card targets enterprise data centres and high-performance computing clusters needing reliable throughput for virtualisation and large data set movement.

Sustained Load Behaviour

The adapter is designed for continuous data-intensive workloads rather than brief burst traffic. Its dual-port architecture distributes bandwidth across two independent 10Gbps channels, helping maintain consistent throughput during prolonged transfers. Efficient power consumption and hardware offloads reduce host CPU overhead, supporting stable performance when handling demanding enterprise applications over extended periods.

PCI Express Interface Limits

The card installs into a standard high-profile PCI Express slot, using the bus for high bandwidth and low latency communication. Practical throughput is governed by the PCIe link width and generation available on the host motherboard, which determines the ceiling for the dual 10Gbps ports. The LC connectors require compatible multimode fibre patch cables to complete the physical link.

Questions about this item

How much power does the X520-SR2 draw under sustained 10 Gbps loads?

The adapter is designed for efficient power consumption during continuous data-intensive workloads, keeping thermal output manageable in standard server airflow.

Which fibre cables and transceivers are required to use the dual LC ports?

The card uses 10GBase-SR optics with LC connectors, so you need multimode fibre patch cords and matching SFP+ SR modules for each port.

Will the high-profile bracket fit alongside older PCIe x8 cards in a legacy server chassis?

The high-profile form factor occupies a standard full-height slot, so it fits in the same chassis space as earlier generation x8 server adapters.
