Problems solved by technology

On the Intel Purley platform, the LED of the NVME hard disk is directly controlled by the CPU. The CPU on the previous platform cannot directly control the LED of the NVME, so other control methods are required to control the LED of the NVME
For the LEDs currently used in the industry, there are generally defective products in the welding process. On the one hand, they are already defective products before welding. light up

Abstract

The invention discloses an NVME LED testing system which comprises the components of a to-be-tested hard disk LED, a CPLD which is arranged at the front side of the hard disk back board and is connected with the hard disk, a CPU and a BMC, wherein the CPU and the BMC are connected with the CPLD. A slimline connector at the back surface of the hard disk back board is connected with the CPU. A signal connector at the back surface of the hard disk back board is connected with a BMC. The invention further discloses an NVME LED testing method. On a Purley platform, a sideband signal on the slimlineconnector is used for satisfying a requirement for controlling the NVME led by a VPP module of the CPU of the platform. On other Intel platforms, the IIC signal of the BMC is used for controlling theNVME led. The NVME LED testing system has advantages of ensuring normal operation of a server LED, improving working efficiency through quickly testing the LED, shortening processing time and reducing cost.

Description

technical field [0001] The invention relates to the technical field of hard disk detection, in particular to an NVME LED detection system and detection method. Background technique [0002] At present, in the field of server storage, server storage capacity and storage speed are important indicators for evaluating the performance of a server. The server storage device will be equipped with three LED lights to indicate its corresponding information, and these three lights are green light, red light and blue light respectively. The green light means in place, the red light means error, and the blue light is used to locate the hard disk. The storage rate of the server is getting higher and higher, and the NVME hard disk is the device with the fastest storage rate in the industry and is gradually becoming popular. On the Intel Purley platform, the LED of the NVME hard disk is directly controlled by the CPU. The CPU on the previous platform cannot directly control the LED of th...
