Abstract

The invention provides a design method for lighting backplanes of hard disks of multiple NVMe (non-volatile memory expresses), and belongs to the field of backplanes of hard disks of servers. The design method includes design steps of leading out a group of VPP (virtual pin ports) signal wires on each controller of a motherboard and transmitting the VPP signal wires to the backplanes via connectorsideband channels of each port; transmitting VPP addresses to backplane sides in a cyclic manner by the controllers and analyzing address information after data streams transmitted by the controllersare received by the backplane sides; transmitting hard disk lighting information of corresponding disk positions to the backplanes by the controllers if simulated VPP addresses of backplane channelsare identical to the addresses transmitted by the controllers; converting serial data streams on VPP into parallel signals by the backplanes, lighting backplane lamps of corresponding ports and uploading monitored hard disk in-place information to the controller. The design method has the advantages that the problem of incapability of normally lighting Locate lamps of existing backplanes of existing hard disks of existing NVMe can be solved by the aid of the design method, address wire information is added into connectors, and accordingly the multiple NVMe can be flexibly configured.

Description

technical field [0001] The invention relates to the field of server hard disk backplanes, in particular to a design method for realizing the lighting of multiple NVMe hard disk backplanes. Background technique [0002] With the continuous improvement of the performance of CPU and graphics card, the computing bottleneck of the server has gradually shifted to the storage device, and the storage technology has also been upgraded accordingly. The transmission rate of the hard disk has been increased from 6G to 12G, and will gradually increase to 24G. Based on the original SATA / SAS mechanical hard disk, new hard disk types such as SATAe / M.2 / NVMe are gradually derived, and the mainstream hard disk form is also upgraded from the original mechanical hard disk to SSD. In this context, higher requirements are put forward for the compatibility of the hard disk backplane of the server. Mainstream computing server backplanes generally support mixed insertion of SATA / SAS / NVMe hard disks,...
