SolarFlare SFN7322F SFP+ Dual-Port 10GbE PCIe 3.0 Onload PTP SolarCapture Pro Server I/O Adapter. On Flareon (8000 and 7000 series) adapters with a SolarCapture Pro key installed the “SolarCapture Pro” feature set is enabled, which includes the following.

ExaNIC X4 SUB-MICRO LATENCY QUAD-PORT 10GBE NETWORK INTERFACE CARD Exablaze's ExaNIC is an ultra low latency network interface card. Typical latency is under a microsecond application to application for small Ethernet frames (using the native API) and approximately 1.1 microseconds for small TCP and UDP payloads (using the transparent socket acceleration library).

The SFN7322F eliminates the need for a secondary server adapter and dedicated. The SFN7322F enables nanosecond. Product TypeComputer Internal Network Cards. clock distribution. Product Details. I would like to enable hardware timestaming for all traffic in and out of an interface. The NIC is a SolarFlare SFN7322F. The idea is to use the HW stamps in the traffic to compute precise end to end latencies in some of the apps running in the box (some of which I do not have the source code for). Solarflare, the leader in application-intelligent 10 Gigabit Ethernet networking software and hardware, today announced the launch of its family of powerful packet capture software. The first ...Managing hardware accelerator cards like GPUs or high-performance NICs in Kubernetes is hard. The special payload (driver, device-plugin, monitoring stack deployment and advanced feature discovery), updates and upgrades, are tedious and error-prone tasks, and often third-party vendor knowledge is needed to accomplish these steps.

Hardware-based timestamping, implemented well, should give accurate and deterministic results. The next problem is one of resolution – hardware timestamping cards usually have a resolution of around 4ns – that’s about the same as the maximum useful clock speed in the FPGAs generally used to implement them.
