SFN7322F

Flareon Ultra SFN7322F Dual-Port 10GbE PCIe 3.0

PTP Server I/O Adapter with Hardware Time Stamping

Flareon™ Ultra SFN7322F dual-port 10G Ethernet SFP+ server adapter combines accurate host clock synchronization and precise hardware packet time stamping with unmatched message rates and ultra-low latency 10G Ethernet. The SFN7322F delivers unmatched precision and performance on a single data network and in a single PCIe slot for financial services and other enterprise data centers with the industry’s lowest power consumption for additional cost savings.

The SFN7322F provides a comprehensive

IEEE 1588 precision time protocol solution which includes a unique PTP daemon (PTPd v2) with advanced features. The SFN7322F eliminates the need for a secondary server adapter and dedicated appliances, as well as additional physical networks, otherwise required for clock distribution.

High-Precision Hardware Time Stamping

The SFN7322F performs high-precision hardware time stamping of all received

Ethernet frames at line rate on both ports.

The SFN7322F enables nanosecond network performance analysis, precise realtime packet capture, and accurate Service

Level Agreement (SLA) measurements.

The SFN7322F driver is compatible with the

SFN7122F, and seamlessly interfaces to host software time synchronization solutions that utilize the standard Linux socket option

SO_TIMESTAMPING.

Complete Time Synchronization Solution

Solarflare provides its enhanced PTPd v2 daemon with unique features to enable a complete solution to synchronize the host server clock to the network master clock:

• Dual-clock servos

• PTP clock failover with bonding

• Hybrid multicast mode

• PTP operation in VLANs

Ultra-Low Latency

With OpenOnload ® , the SFN7322F delivers packets directly to user space, bypassing kernel and network overheads while maintaining complete application compatibility and protocol compliance. This integrated solution accelerates latency-sensitive applications where precision time is critical, such as high performance computing, cloud, grid, and financial services in enterprise data center environments.

The Flareon Ultra SFN7322F supports PCIe

3.0 with ultra-low latency features such as direct packet transfer (Tx PIO) mode, which includes a templated send API. The SFN7322F reduces CPU load with hardware acceleration features that optimize packet delivery, such as UDP multicast replication, integrated layer

2 switching capability, VLAN insertion / removal, and TCP segmentation offload (TSO).

SFN7322F Highly Accurate Time Synchronization and Precise Hardware Time Stamping

Solarflare’s SFN7322F utilizes a highly stable and precise Stratum 3 clock source, which enables a server to be synchronized to a data network clock with greater precision. Standard crystals can drift significantly, resulting in an inferior solution for clock synchronization and time stamping. For example, between PTP synchronization cycles a typical 15 PPM crystal can drift up to 4000% more than the SFN7322’s 0.37 PPM Stratum 3 clock source. Consequently, the SFN7322F significantly improves server clock accuracy and time stamp precision. SFN7322F also features a

Pulse Per Second (1PPS) input circuit that can be used to calibrate the PTP offset, and an accurate

1PPS output circuit aligned to the SFN7322F's Stratum 3 clock.
