SFN5322F dual-port enterprise SFP+ server adapter combines precision time
synchronization with ultra-low latency 10G Ethernet, both accelerating time synchronization
and providing the industry’s best application performance on a single data network and in a
single PCIe slot. The SFN5322F delivers unmatched scalable performance for data centers
and the industry’s lowest power consumption for additional cost savings.
SFN5322F High-Precision Time Synchronization
Solarflare’s SFN5322F utilizes a high-precision clock source, which meets the rigorous requirements
for use in a Stratum 3 clock system for network synchronization. SFN5322F’s high-precision clock
stability enables servers to synchronize to a data network clock with greater precision, and serve as a
highly stable and precise clock source. Alternative products utilizing crystals can drift significantly over
time, temperature, and age, resulting in an inferior clock synchronization solution. For example, between
synchronization cycles a typical 15 PPM crystal can drift 4000% more than the SFN5322’s 0.37 PPM
Stratum 3 clock source, significantly impacting time stamp precision. Consequently, in PTP applications
the SFN5322F limits drift and increases precision, which are key factors for high-precision PTP clock
synchronization.
The SFN5322F accelerates time synchro-
nization by performing high-precision hard-
ware time-stamping of IEEE 1588 Ethernet
frames together with high-performance,
ultra-low latency application acceleration.

The SFN5322F eliminates a secondary
server adapter (freeing PCIe slots) and
dedicated appliances, as well as additional
physical networks, which would otherwise be
required for clock distribution, while facilitat-
ing slave servers to precisely synchronize
internal clocks to a network master clock.
Combining ultra-low latency data transfers
with clock synchronization on a single net-
work simplifies latency-sensitive applications
where clock synchronization is critical, such
as financial services and distributed processing
environments.

The SFN5322F driver is compatible with the
SFN5122F product and seamlessly interfaces
to host software time synchronization solutions
that utilize the standard Linux socket option
SO_TIMESTAMPING, such as PTPv1 or
PTPv2 daemons, which implement the IEEE
1588 time synchronization protocols. Driver
interfaces to kernels that predate SO_TIME-
STAMPING are also available.
