Problems solved by technology

[0005] The purpose of the present invention is to provide a PCIE riser card, which aims to solve the poor versatility of the riser card scheme in the prior art. Even if the NVME riser cards of different motherboards have the same functional requirements, they may not be shared; in addition, the backplane needs additional The cable is connected to the VPP interface of the motherboard, which causes waste of resources and is not conducive to management and assembly problems

Abstract

The invention relates to the technical field of data storage, and provides a PCIE Riser card and hard disk VPP lighting device. The PCIE Riser card comprises at least two NVME hard disk interfaces anddial switches respectively corresponding to the at least two NVME hard disk interfaces; one ends of the dial switches are connected with VCC ends of the NVME hard disk interfaces and the other ends of the dial switches are grounded; a hard disk backboard is connected with a CPU through a PCIE slot; each of the NVME hard disk interface is connected with a reserved pin of the PCIE slot; the reserved pin of the PCIE slot is used for importing a hard disk lighting signal. According to the PCIE Riser card and the hard disk VPP lighting device, the problem that NVME Riser cards of different mainboards cannot be shared is solved, and VPP signals are imported, so that extra demands for cables are decreased, the product complexity and cost are reduced and the universality of Riser cards is improved.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a PCIE Riser card and a hard disk VPP lighting device. Background technique [0002] In the existing NVME Riser card circuit design, such as figure 1 The circuit shown is used to realize the multiplexing of PCIE external card and NVME hard disk interface. According to Intel's virtual pin interface (Virtual Pin Port, VPP) lighting mechanism, NVME hard disks hung under different PCIE interfaces of the CPU, in addition to specific I2C addresses, also have corresponding strap pins, called Cable IDs, each Cable ID consists of 4-digit binary numbers, which are implemented with four sets of pull-up and pull-down resistors on the motherboard or Riser card. According to the NVME backplane management specification, two NVME disks share an I2C address, but each NVME disk has a specific CableID. There is a fixed correspondence between the PCIE interface of the CPU, the I2...
