Background
At present, with the increase of the calculation amount of the server, the demands of people on hard disks are also higher and higher, and the capacity quantity of the hard disks in the server is increased. The number of hard disks in one server reaches as many as several tens. While SSDs (SolidState Drives; solid state drives) and NVMEs are increasingly replacing HDDs (HARDDISKDRIVE; hard drives), a lot of heat is generated due to their high speed computation. As the temperature increases, the electronics in the server may overheat, causing a malfunction or enter overheat protection to self-lock. For the hard disk, once the threshold value set in the hard disk is exceeded, the hard disk is subjected to frequency reduction due to overheat protection, so that the calculation speed is greatly reduced. In severe cases, hard disk life is greatly reduced. Therefore, monitoring the hard disk temperature is an important task for server development.
At present, the monitoring of the temperature of the hard disk is usually realized based on hardware monitoring equipment, but the monitoring of the temperature of the hard disk by the hardware monitoring equipment generally has the following disadvantages: 1. the economic cost is high; in the existing technical scheme for monitoring the hardware temperature, hardware monitoring equipment is required to be additionally arranged, and in order to ensure the accuracy of the monitored hardware temperature, the number of the hardware monitoring equipment is required to be large; 2. the accuracy of the hard disk temperature monitored by the hardware monitoring equipment is not high; because a large number of computing modules are arranged in the hard disk, the internal temperature is far higher than the external temperature, and the hardware monitoring equipment is usually arranged on the back plate, the actual temperature in the hard disk cannot be accurately obtained by the hard disk monitoring equipment; in addition, the hard disk and the backboard are usually arranged at the position of the air inlet of the server, so that the temperature monitored by the hard disk monitoring equipment arranged on the backboard is lower than the actual temperature of the hard disk; 3. the bandwidth waste rate is high; based on the fact that the hardware monitoring equipment monitors the temperature of the hard disk, in the prior art, the hardware monitoring equipment monitors the temperature of the hard disk through a smart command, in order to ensure the accuracy of reading the temperature of the hard disk, the temperature of the hard disk needs to be repeatedly read within a certain time interval, and when the hard disk frequently executes reading operation, a large amount of bandwidth is wasted, and the performance and consistency of the hard disk are adversely affected; 4. the hardware monitoring equipment has hysteresis, namely when the hardware temperature is monitored by the hardware monitoring equipment, whether the hardware temperature is abnormal or not can only be monitored, and early warning can not be carried out on the hardware temperature.
