PM45052中文资料PAX 52xG4 Gen 4 Automotive-Qualified PCIe Switch数据手册Microchip规格书

描述 Description

The Switchtec Gen 4 PM42052 PAX Advanced Fabric PCIe switch is a programmable, high reliability switch supporting high performance PCIe fabric connectivity to a shared pool of GPUs, NVMe, SSDs and other endpoints, multi-host sharing of single-root input/output virtualization (SR-IOV) endpoints, 52 lanes, 28 ports, and hot- and surprise-plug controllers for each port.  PAX switches features advanced error containment, comprehensive diagnostics and debug capabilities, a wide breadth of I/O interfaces, and an integrated MIPS processor. PAX switches utilize a system-on-chip architecture that optionally enables customer differentiated solutions through firmware customization and enhancements.

Applications for the PAX family include scalable multi-host systems, SR-IOV-enabled JBOFs, composable GP-GPU fabrics, disaggregated systems and rack scale architectures.
