Abnormal power-down testing system for hard disk

Abstract

The invention provides an abnormal power-down testing system for a hard disk. The abnormal power-down testing system comprises a plurality of testing hosts, a PDU (Power Distribution Unit), a testing server, to-be-installed system software and to-be-tested system software, wherein each testing host is connected with the testing server; the PDU is connected with the testing server; the PDU provides power for all the testing hosts; each testing host is provided with a hard disk connector; the testing server is provided with a monitoring module and a control module; the monitoring module is used for recording the operating state of each testing host; the control module is used for controlling the PDU so as to control the power-on time and the power-off time of each testing host. According to the abnormal power-down testing system for the hard disk, a to-be-tested hard disk is placed on one testing host, and test programs run on the server, so that a plurality of solid-state hard disks can be tested at the same time, and the test number can be regulated in a programming manner, a power-down test with various strengths can be met, and the testing efficiency and testing effect are both improved.

Description

technical field [0001] The invention relates to the field of hard disk testing, in particular to a testing system for hard disk abnormal power failure. Background technique [0002] The performance and erasure loss of the hard disk should be considered in the design of the hard disk, and the write buffer will be used to reduce the operation of the nand flash or the magnetic track. In actual user use, it is difficult to avoid unsafe abnormal power-off operations during the process of reading and writing hard disks. When an abnormal power failure occurs, the data in the buffer may not actually be written into the nand flash or the magnetic track. The abnormal power failure will cause data loss in the hard disk and affect the normal use of the user. [0003] Therefore, the data security index of the hard disk during abnormal power-off operation is an important test and evaluation index of the hard disk, and it is also a must-test item. At present, the abnormal power failure t...

Problems solved by technology

Manually observe and test whether there are abnormal phenomena such as blue screen or crash during the boot process of the test host. If there is, the test will fail

[0012] The defect of method 1 is: the whole test process requires human participation, which is a waste of human resources; and because the power supply of the test host needs to be manually plugged and unplugged during the test process, the number of tests will be greatly limited, resulting in insufficient test intensity for solid-state drives.

[0014] On the basis of method 1, the power-on and power-off operations of the test host are integrated and controlled, and multiple test hosts can be controlled to test simultaneously through hardware connections, but this method has weak programmability

It is still necessary to manually observe and test whether the host has abnormal phenomena such as blue screen or crash during the boot process. If there is, the test will fail.

The defect of method 2 is: the entire testing process requires human participation, wasting human resources

Although multiple platforms can be tested at the same time, because the power-on and power-off operations of the test host are integrated control, if an error occurs in one of the test hosts, the entire test will stall

The test interval is fixed and cannot be changed, and the programming ability is poor
