Intel X520-SR2 10GBase-SR adapter

The Intel X520-SR2 is a 10 Gigabit Ethernet server adapter with two SFP+ ports for short-range fibre connectivity. It installs in a PCI Express x8 slot and targets data-centre workloads such as high-performance computing clusters, database nodes and video-on-demand streaming servers. The card is RoHS compliant and built for PC platforms requiring scalable 10 GbE links.

Sustained 10 GbE throughput

Dual 10GBase-SR ports maintain line-rate traffic under continuous load from multi-core servers running HPC jobs or database replication. The PCI Express x8 host interface supplies enough bandwidth to keep both ports saturated without host-side bottlenecks. This makes the adapter suitable for environments where sustained 10 GbE performance matters more than burst speed.

Thermals and power in normal use

The plug-in card form factor relies on server chassis airflow for cooling during typical operation. RoHS-compliant construction meets environmental standards for deployment in regulated facilities. Power draw scales with link utilisation on the two SFP+ ports, and the 5.7 inch width fits standard low-profile brackets.

Questions about this item

Does the Intel X520-SR2 generate much heat when running at 10 Gbps all day?

The 10GBase-SR adapter plugs into a PCI Express x8 slot and uses two SFP+ ports; power draw and thermal output stay within the slot specification.

What slot and cabling must I already have for the X520-SR2 to work?

You need a free PCI Express x8 slot and two multimode fibre cables with SFP+ transceivers for the 10GBase-SR links.

Will this 10GBase-SR card link with my older 1 GbE switch ports?

The X520-SR2 operates at 10 Gbps over SR optics; it does not negotiate down to 1 GbE on the same fibre interface.
