PCIe

There are multiple reasons to need a PCIe switch. These can include expanding PCIe connectivity to more devices than the CPU is capable, to extend a PCIe fabric across multiple hosts, to generate failover support, or to increase device-to-device communication bandwidth in limited scenarios. With the advent of PCIe 4.0 processors and devices such as graphics, SSDs and FPGAs, an upgrade from the range of PCIe 3.0 switches to PCIe 4.0 was needed. Microchip has recently announced its new Switchtec PAX line of PCIe Switches, offering up to 100 lane variants supporting 52 devices and 174 GBps switching capabilities. For readers not embedded in the enterprise world, you may remember in the past we have had a number of PCIe switches enter the consumer market...
