Intel X520-SR1 10Gbps Server Adapter

The Intel E10G41BFSR is a single-port 10Gbps network card built on the Intel 82599ES controller. It connects through a PCI Express 2.0 x8 slot and provides one LC connector for short-range fibre. The adapter supports IEEE 802.3, 802.1Q, 802.1p, 802.3ad, 802.1ae and 802.1as standards for enterprise networking.

Suited for virtualised hosts needing SR-IOV and VMDq

This card targets servers that require hardware-assisted I/O virtualisation with Single-Route I/O Virtualisation and Virtual Machine Device Queues. It also handles iSCSI, NFS and FCoE for converged storage traffic. It is not for deployments that need more than one physical port or that rely on copper twisted-pair cabling.

PCI Express 2.0 x8 electrical requirement

The adapter needs an x8 electrical link on a PCI Express 2.0 bus to deliver the full 10Gbps throughput. A slot wired for fewer lanes will limit bandwidth and may prevent the card from operating at its rated speed. Verify the motherboard or riser provides an x8 electrical connection before purchase.

Questions about this item

What type of PCI Express slot does the Intel E10G41BFSR require?

The card uses a PCI Express 2.0 x8 interface and fits a compatible x8 or larger slot on the motherboard.

Will the E10G41BFSR negotiate a link with 1 Gbps switches that only support IEEE 802.3?

The adapter complies with IEEE 802.3 standards, so it will negotiate the highest common speed with the connected switch.

Which LED behaviour confirms the Intel E10G41BFSR has established a 10Gbps fiber link?

A steady link LED on the LC port indicates a valid 10Gbps connection over the short-range fiber cable.
