Description

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.

Flareon Ultra SFN7122F delivers the industry’s lowest latency and highest message rates accelerating applications, such as high performance computing, cloud, grid, big data, storage, Web 2.0, and financial services in enterprise data center environments. Featuring a full set of stateless offloads, SFN7122F reduces CPU processing loads for the most demanding network tasks.
