PCIe Switches

The Marvell® Structera® S series of PCIe switches is designed to enable AI infrastructure and fanout connectivity. These devices offer ultra-low latency, high radix connectivity, and advanced fabric capabilities required for next-generation AI and HPC workloads. With an industry-first 256 lanes, the Structera S 50256 device eliminates the need for multiple smaller switches, thereby flattening the network, reducing latency and enhancing performance of AI systems. Structera S switch devices are also available for CXL applications.

  • PCIe 5.0 compliance
  • Configurable 16 ports (x16) or 32 ports (x8)
  • Up to 2 TB/s switching capacity
  • Advanced traffic management with virtual output queues (VOQ)
