SS22-0B00-02 Key Technical Features

🔹 Industry-Leading PCIe 5.0 Performance

The SS22-0B00-02 supports the PCIe Gen 5.0 (32 GT/s) specification, delivering up to 1024 Gb/s (128 GB/s) of raw bandwidth per port (x16). This makes the chip an ideal interconnect solution for hyperscale computing systems, AI/ML clusters, and high-performance storage systems.

🔹 72-Lane, 36-Port Massive Connectivity

Offering massive connectivity with 72 lanes and 36 ports, it allows designers to:

Fan out CPU PCIe ports to connect to a large number of I/O devices or other subsystems

Build complex PCIe matrix topologies to enable multi-host communication within the chassis

Implement basic switching functions without software configuration

🔹 Embedded Dual-Core ARM Management Core

An integrated dual-core ARM processor provides on-chip management capabilities, simplifying system design and reducing BOM costs.

🔹 SR-IOV and Multi-Host Support

Supports standard SR-IOV (Single Root I/O Virtualization) and multi-host capabilities, allowing multiple hosts to coexist on a single PCIe matrix topology. It also includes TWC (Tunnel Window Connection) for specialized low-latency host-to-host communication, ideal for efficient transmission of short data packets.

🔹 Optimized for Data Centers and AI

The chip is designed to address the pain points of modern data centers:

Reduce latency: Minimize system latency in data-intensive environments

Lower power consumption: Optimize energy efficiency

Simplify connectivity: Deliver maximum PCIe switching performance

Support for NVMe AFA All-Flash Arrays: Optimized for storage systems

Typical Application Scenarios

The SS22-0B00-02 covers a wide range of scenarios, from traditional servers to cutting-edge AI infrastructure:

AI/ML/DL Acceleration Clusters: Supports hyper-converged architectures, enabling resource sharing via Single Root I/O Virtualization (SR-IOV) and efficient connectivity to accelerators such as GPUs and FPGAs.

NVMe All-Flash Arrays (AFA): Optimized for NVMe storage systems, supporting the construction of high-performance, low-latency storage backplanes.

Data Centers and Servers: Connects a large number of I/O devices and subsystems by fan-out the CPU’s PCIe ports, simplifying cabling and reducing power consumption.
