Intel E10G41BFSRBLK 10Gbps network card

SKU CH-6BWM-SD115 MPN E10G41BFSRBLK

A 10Gbps plug-in network card using 10GBase-SR optics for short-range fibre links

  • Rated speed10 Gbit/s
  • Key featuresProduct Type: 10Gigabit Ethernet Card Network Technology: 10
  • 10Gbps throughput for demanding data centre workloads
  • Single-port 10GBase-SR fibre connectivity
  • PCI Express plug-in card form factor
  • Intel X520 server adapter reliability
  • Scalable I/O for virtualised and unified storage environments

Intel X520-SR1 10Gbps Server Adapter

The Intel X520-SR1 is a 10Gbps plug-in network card built for data centre servers running virtualised workloads, HPC clusters, database nodes or video-on-demand streaming. It targets administrators who need flexible, scalable I/O for multi-core platforms.

10GBase-SR capacity and headroom

The adapter delivers 10Gbps over 10GBase-SR optics, providing bandwidth headroom for consolidated virtual machines and storage traffic. It runs out when aggregate demand exceeds a single 10Gbps lane or when longer-reach fibre is required.

Low-profile bracket changes deployment

The bundled low-profile bracket lets the card fit in 1U and other space-constrained chassis where a full-height bracket would not install. Without it the adapter would be limited to full-height server slots only.

Questions about this item

Will the 10Gbps X520-SR1 card work in an older PCIe 2.0 server slot?

The card uses a PCI Express interface and will negotiate down to the slot speed; 10Gbps throughput requires at least a PCIe 2.0 x8 or PCIe 3.0 x4 link.

How do I verify the 10GBase-SR link is running at full 10Gbps after install?

Check the adapter LEDs — solid green indicates link up — and confirm 10 Gbps speed in the OS network settings or switch port counters.

Does the Intel E10G41BFSRBLK include SFP+ optics or must I buy them separately?

The X520-SR1 ships with a short-range SFP+ transceiver installed; LC duplex multimode patch cables are not included and must be purchased separately.
