Temperature detection method and device

Abstract

The embodiment of the invention discloses a temperature detection method and device, and can accurately detect the temperature of each SSD (Solid State Disk), identify which sensors fail and avoids a phenomenon that a system executes wrong processing strategies. The method of the embodiment of the invention is applied to a storage array system and comprises the following steps: obtaining a first temperature value of a disk frame air inlet through a first sensor; obtaining a second temperature value of the air inlet of each SSD in the disk frame through a second sensor; obtaining a third temperature value of each SSD processor in the disk frame through a third sensor; according to a preset rule, analyzing the first temperature value, the second temperature value and the third temperature value to judge whether the corresponding sensors fail or not; and in a subsequent temperature detection process, neglecting the sensors which are judged as failed sensors.

Description

technical field [0001] The invention relates to detection technology, in particular to a temperature detection method and device. Background technique [0002] Solid State Drives (SSDs) have the advantages of high performance and low latency, and are widely used in storage array systems. SSD is a key component of a storage array system, and its reliability becomes an important factor in examining the performance of a storage array system. Among them, the data retention capacity of SSD has a great relationship with the temperature. The higher the temperature, the worse the data retention capacity; at this time, it is necessary to rely on the inspection mechanism inside the SSD to ensure the accuracy of the data. Usually, the higher the temperature, the corresponding inspection The shorter the period, the more frequently the data is moved, which has a certain impact on the life of the SSD. Therefore, temperature is an important factor affecting the reliability of the SSD. ...

Problems solved by technology

[0004] However, the above temperature detection scheme has the following disadvantages: the temperature detection of each SSD in the hard disk enclosure is carried out independently, and the judgment whether the temperature of the SSD exceeds the standard only depends on its corresponding temperature sensor. During this process, it is impossible to determine whether the collected temperature is accurate. If The temperature sensor of an SSD itself is faulty, and the current system cannot recognize it, causing the system to implement incorrect processing strategies, such as false alarms, incorrect adjustment of SSD inspection frequency, etc.
