May 28, 2020 – To support cloud, data center and hyperscale computing that facilitates advancements in Artificial Intelligence (AI) and Machine Learning (ML), Microchip Technology released to production its Switchtec PAX Advanced Fabric Gen 4 PCIe switch family, enabling fabric topologies. Microchip’s Switchtec PAX PCIe family of switches provides a fabric solution for systems requiring multi-host sharing of Single Root I/O Virtualization (SR-IOV) Non-Volatile Memory (NVMe) Solid State Drives (SSDs), Graphics Processing Units (GPUs) and other PCIe endpoints. The Switchtec PAX devices are Gen 4 PCIe switches. The Switchtec PAX family of switches is available in the following variants: 100-lane, 84-lane, 68-lane, 52-lane, 36-lane and 28-lane. Other PAX family of switches features include:
- Error containment
- Diagnostics and debug capabilities
- I/O interfaces
- Integrated MIPS processor
- Secure boot to prevent execution of unauthorized firmware through public key cryptography.
Applications include GPU workstations, composable General Purpose GPUs (GP-GPU) fabrics, scalable multi-host systems, SR-IOV-enabled JBOFs, disaggregated systems and rack-scale architectures.
