Abstract

The invention discloses a hard disk backplane connection method supporting hard disks with various bit widths. The method comprises the following steps: carrying out packaging compatibility on a cable connector interface of a hard disk backplane; setting a reference clock of the NVME hard disk as an in-board clock in the hard disk backboard; designing cables of the NVME hard disks with different widths, and butting a controller through the cables; setting a dial switch, connecting the dial switch with a CPLD, identifying a working mode by the CPLD through the dial switch, and lighting according to the working mode. By means of the mode, the problem that a current multi-mode hard disk backboard only supports an NVME hard disk with the x4 width and does not support an NVME hard disk with the x2 width and an NVME hard disk with the x1 width can be solved, the specification number of the hard disk backboard is reduced, and the competitiveness of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of hard disk backplanes, in particular to a hard disk backplane connection method and device supporting hard disks with multiple bit widths. Background technique [0002] With the continuous development of the storage market, the demand for data storage continues to increase, the requirements for the capacity, quantity and transmission of the hard disk supported by the server are getting higher and higher, and the requirements for the hard disk backplane are also increasing. [0003] The current multi-mode hard disk backplane can only support x4-bit wide NVME hard disks, such as figure 1 As shown, the hard disk backplane supports 4 x8 high-speed interfaces (such as Slimline x8 high-speed connector interface), the NVME hard disk mode that is connected to the CPU, or the NVME hard disk mode that is connected to the RAID card. The high-speed interface provides x4 for each 2.5-inch NVME hard disk. PCIE interfac...
