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:
- High-performance PCIe fabric connectivity overcoming the limitations of the PCIe Specification for multi-host systems
- Multi-host sharing of SR-IOV NVMe SSDs, GPUs and other PCIe endpoints
- Virtualization of host PCIe domains and SR-IOV endpoints
- Software development kit (SDK) for virtualization of SR-IOV endpoints, and for enclosure management
- One of the industry's most flexible port bifurcation, from x2 to x16 lanes per port
- High port density, with up to 48 ports
- Advanced error reporting
- Error containment for surprise-plug and unplug to prevent system crashes
- Advanced diagnostics and debug features to identify, diagnose and fix problems
- Separate Refclk Independent SSC (SRIS) for cabled PCIe and lower cost system designs
The PCIe switches are sampling now to lead customers. For more information and specs, visit Microsemi's PCI Express Product Portfolio and/or contact [email protected].
