Experience High Performance Networking with Silicom’s P425G2SNx IAONIC SmartNIC Intel® Based

The Silicom P425G2SNx IAONIC is a smart NIC that combines two of the industry’s most sought after features:

A hardware-standard NIC (over PCIe v4) interface with 2 ports of 25G or 1 port of 100G
Ability to offload a complete infrastructure workload from the main host, while still working in line rate.

Silicom P425G2SNx IAONIC is based on an Intel P5700 processor that contains 8/16 X86 cores, an integrated packet processor with 25G/100G interfaces, and an Ethernet MAC using Intel® E810.

Optimize Server Resources with Silicom P425G2SNx IAONIC SmartNIC Intel® Based

With Silicom P425G2SNx NIC, the workloads that usually run alongside the host’s main business logic – including infrastructure workloads and workloads that serve the main server workload – can now be offloaded onto the NIC, rather than consuming CPU power from the main business logic.

Boosting Performance with Silicom’s P425G2SNx NIC: The Benefits of Workload Offloading

Examples of such workloads include:

Network traffic load balancing (hash-based or 5 tuple based)
Network mirroring and forwarding
Complete TLS termination on NIC
Complete IPSec termination on NIC

As a result, the Silicom P425G2SNx NIC supports and enhances use cases such as:

Intrusion detection systems
Telco subscriber billing and SLA monitoring
SDWAN on a NIC
Application delivery controller on a NIC
DNS over HTTPS proxy service
Layer 3 networking offload
PSec bridge on a card

and many more.

Revolutionize Your Server Infrastructure with Silicom P425G2SNx Smart NIC

Depending on the SKU, Silicom P425G2SNx cards employ 8 to 16 x86 CPU cores, the benefit of which is twofold:

Enables immediate asset reuse, meaning that any x86-based software running on the main host can now be ported to the card with minimal effort.
The physical separation of the CPU core from the main host brings the advantage of infrastructure isolation from the main workload.

These workloads and benefits can be available almost instantly by drop-in replacing any standard NIC with the Silicom P425G2SNx smart NIC.
