According to the NVME backplane management specification, two NVME disks share one I2C address, but each NVME disk has a specific Cable ID. The PCIE interface of the CPU, the I2C address of the NVME and the Cable ID have a fixed corresponding relation.
According to different PCIE interfaces connected with a PCIE slot at the mainboard end, the corresponding Riser card uses an up-down pull resistor to realize different Cable IDs, namely the up-down pull resistor is loaded according to a specific pin. Once the BOM is determined, the Riser card needs to be connected to the fixed PCIE slot, and cannot be used on other PCIE interfaces, and the PCIE sequence cannot be changed.
