PCIe combiner device 用于连接多种外设并优化性能。
Computers aren't magical, but PCIX can be divided and merged. This is possible if you locate some hardware components or use extensions from Chinese PCIX modules. Keep in mind the same restrictions apply when splitting as with combining—PCI Express can only be broken down or joined into 16x8x4x2x1 configurations. This applies only to devices directly linked to the CPU, and you can't merge lanes from different CPUs. Considering this, the real-world use is limited. Motherboards can handle some splitting and merging to a certain extent, depending on their design. For example, an AMD Ryzen setup has 24 PCIe lanes, with four Gen3 lanes going to the chipset for multiplexing. This results in up to 7 PCIe 2.0 lanes or various peripherals, depending on the board. So you end up with about 20 PCIe 3.0 lanes directly connected to the CPU—4 assigned to NVMe and 16 to PCIe slots. You can organize them like this: one 16 lanes, two 8 lanes, one 8 lanes, and two 4 lanes. This arrangement helps manage data flow efficiently.
