Dual 40GbE QSFP+ Converged Adapter

The Dell Solarflare SFN8542 is a full-height converged network adapter designed for rack-mount servers. It provides two QSFP+ ports, each capable of 40GbE throughput, enabling high-bandwidth connectivity for storage and compute clusters. The card uses the SF10-050122 controller to offload protocol processing from the host CPU.

Capacity suited to twin-port 40GbE fabrics

This adapter comfortably handles dual 40GbE links for latency-sensitive workloads such as high-performance storage access or inter-node messaging. Headroom is limited to the two physical ports; environments that require additional 40GbE connections or higher single-port speeds will need extra adapters or a different platform.

Questions about this item

Will the 40GbE QSFP+ ports on this SFN8542 card link with my existing 10GbE switches?

The card presents dual 40GbE QSFP+ ports; connecting to 10GbE gear requires compatible QSFP+ to SFP+ breakout cables or transceivers that match the switch side.

How can I verify the SFN8542 is operating at 40GbE after installation?

Check the link status LEDs on each QSFP+ port and confirm the OS reports a 40 Gb/s negotiated speed for both interfaces.
