Description
Technical Field
The present invention relates to the field of servers, and more particularly, to a method, a system, a computer device, and a readable medium for protecting a mechanical hard disk.
Background
Although the speed of the mechanical hard disk is not as high as that of the solid state hard disk, most of the current servers use the mechanical hard disk, and the solid state hard disks are relatively few. Ordinary solid state hard drives are more expensive than mechanical hard drives, enterprise-level solid state hard drives are cheaper, and the capacity of the solid state hard drives is generally small, so that if servers all use the solid state hard drives, the cost is very high, and the ordinary enterprises are hard to bear. The server stores important mass data and has high requirements on the capacity of the hard disk. However, the capacity of a single block of the existing server mechanical hard disk can reach more than 2TB, and the capacity of the mainstream server mechanical hard disk reaches about 10 TB. Even hard disks with 14TB and 18TB are going to be marketed. Moreover, the traditional mechanical hard disk has been used for decades, the technology is mature, the reliability is excellent, the damaged mechanical hard disk can be maintained, data is lost, and the damaged mechanical hard disk can be retrieved at a high rate through professional data recovery software. The solid state disk starts later, and although the speed has absolute advantage, the solid state disk is stored in a wafer level mode, once the solid state disk is damaged, data can hardly be retrieved. In addition, the solid state disk loses data and is hardly restored again. However, in the mechanical hard disk, since the motor drives the hard disk to rotate for reading, the hard disk needs to be placed vertically or horizontally to prolong the service life of the hard disk.
The existing system basically uses vertical or horizontal placement to prolong the service life of the hard disk, but in fact, the chassis of the system or the bracket of the hard disk can cause the hard disk to incline or even vibrate after long-time use or under the condition of too large design tolerance, the inclined and vibrating hard disk bracket is easy to cause damage to the hard disk after long-time use, and the user must replace the hard disk at this time. The conventional hard disk bracket is not provided with an angle detection device, when the bracket is inclined or abnormally vibrates, a BMC monitoring end cannot be effectively informed to monitor, and a worker is dispatched to handle the inclined vibration condition of the hard disk in time, so that the hard disk is in an abnormal operation mode for a long time, and the hard disk is easy to damage, and the situations of data loss and the like are possibly caused.

In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for protecting a mechanical hard disk. Fig. 1 is a schematic diagram illustrating an embodiment of a method for protecting a mechanical hard disk according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
