Solarflare Communications, Inc. SFN7322F 10Gbps network card

10Gbps dual-port adapter

The Solarflare SFN7322F is a new 10Gbps network card with two SFP+ slots on a PCI-Express interface. It delivers high-precision hardware time stamping on both ports at line rate for network analysis and SLA measurements. The card includes a comprehensive IEEE 1588 precision time protocol solution with a unique PTP daemon. This adapter eliminates the need for a secondary server adapter or dedicated appliances for clock distribution.

Suits latency-sensitive deployments

Engineers who need nanosecond-level timestamping on two 10Gbps links will benefit from the hardware PTP implementation. Builders requiring more than two ports or a different physical connector should look at other models. The card targets environments where precise real-time packet capture and clock synchronisation are primary requirements. It is not intended for general-purpose connectivity without timing demands.

Two SFP+ ports at 10Gbps

The SFN7322F provides exactly two SFP+ slots operating at 10Gbps each over a PCI-Express bus. This port count and speed combination determines whether the adapter fits the available slots and cabling plan. No other port configurations or speeds are offered by this specific model. Verify the host system has a compatible PCI-Express slot and the required SFP+ transceivers.
