Dual 10Gbps SFP+ Network Adapter

The Solarflare SFN7122F is a PCI-Express network interface card providing two 10Gbps SFP+ ports for high-throughput server and workstation environments. It targets administrators building low-latency fabrics for high-performance computing, financial services, or data-intensive cloud workloads.

Replacing Single-Port or Slower NICs

This dual-port adapter replaces single-port 10GbE cards or older 1GbE interfaces when aggregate bandwidth or link redundancy is required. The upgrade is justified when applications saturate a single 10Gbps lane or when failover paths must exist without adding a second physical card.

Sustained Load With Stateless Offloads

Under continuous traffic the card uses a full set of stateless offloads to reduce CPU processing overhead for demanding network tasks. OpenOnload technology bypasses kernel networking stacks to maintain consistent message rates and low latency during prolonged high-volume transfers without degrading host performance.

Questions about this item

What PCI-Express slot size does the SFN7122F need to fit?

The SFN7122F installs in a standard PCI-Express slot inside the server chassis.

Which step is often missed when installing the SFN7122F?

After seating the card, the two SFP+ transceivers must be inserted and the fibre cables latched before the link will come up.

What will need replacement on the SFN7122F over time?

The SFP+ transceivers are the only field-replaceable parts; the card itself has no moving components.
