PS225 - Dual-Port 25GbE PCIe Ethernet SmartNIC

Stingray™ 2x25Gb High-Performance Data Center Smart NIC

Currently Viewing:

The Stingray PS225 SmartNIC is purpose-built to enable solutions in the evolving data center. The board integrates powerful networking and processing subsystems for SmartNIC applications including data plane acceleration and software-defined storage (SDS) including NVMe-over-Fabrics (NVMe-oF). The PS225 is designed in a low-profile, half-length form factor for both half-height and full-height PCIe slots.

The PS225 SmartNIC features the BCM58802 high-performance data center SoC, which incorporates a NetXtreme E-Series advanced network controller, a high-performance ARM CPU block, PCI Express (PCIe) Gen3 x8 interface, key accelerators for compute offload and a high-speed memory subsystem including L3 cache and DDR4 interfaces, all interconnected by a coherent Network-on-chip (NOC) fabric.

The network interface is powered by the latest generation of NetXtreme controller technology, delivering high packet rate and low latency. The powerful TruFlow™ configurable flow accelerator adds a powerful packet inspection and processing capability in the hardware, moving common flow-processing workloads such as Open vSwitch (OVS) into hardware thereby freeing CPUs for application workloads. Support for the NVMe-oF standard is enabled over RoCE (RDMA over Converged Ethernet) v1 & v2 as well as over TCP and other transports, ensuring a future-proof and scalable platform for the deployment of disaggregated storage over a range of topologies.

The ARM CPU subsystem features eight ARMv8 Cortex-A72 CPUs at 3.0 GHz, arranged in a multi-cluster configuration.

The PS225 adapter provides two SFP28 connectors for dual-port 25 Gb connectivity. The interface supports optical modules or DAC (direct-attach copper) cables.

The Stingray family of products is supported by a comprehensive Software Development Kit providing a complete turn-key Linux distribution, and the open programming model enables application porting and development with minimal effort. The platform uses standard Linux and standard GNU tools and libraries. All drivers for the Stingray SoC are upstreamed to and all peripheral interfaces use standard device drivers.
