PCIe Switch Chiseled For Fabric Connectivity

Microsemi enhances its Switchtec PCIe advanced Fabric Switch (PAX) to provide high-performance fabric connectivity and composability for multi-host graphics processing unit (GPU) and NVMe solid state drive (SSD) systems. The switch provides a scalable, low-latency and cost-effective multi-host interconnect for a network of GPUs, NVMe SSDs and other PCIe endpoints. It can be used to create a flexible fabric interconnect to a shared pool of GPUs and/or NVMe SSDs using standard operating system drivers. System management is simplified through a fabric application programming interface (API), significantly reducing time to market and development cost for multi-host systems.

 

Switchtec PAX family offers switches from 96 lanes to 24 lanes, providing:
