System for controlling hard disk sequential start

Abstract

A system used for starting-up control hard disc in sequence comprises power supply module, at least one processing module and at least one control module. The said system is applied in electronic system with at least the first and the second hard discs and it can control total power supply signal value generated by start-up hard discs to not be over over-current protection value of power supply module for ensuring system start-up properly.

Description

technical field [0001] The present invention relates to a system for controlling the sequential start of hard disks, in particular to a system which is applied to an electronic system with multiple hard disks and adopts a delay technology to control the sequential start of the hard disks. Background technique [0002] A general system (computer system or service system) has three major components: a central processing unit (CPU), a hard disk (hard disk) and a memory (memory), among which the hard disk, CPU and memory occupy an absolutely important position. As the most important external storage device of the system (other auxiliary storage devices include floppy disk, CD, flash memory, tape, etc.), the hard disk forms the data storage center of the entire system, and most of the programs and data used by the system during operation are stored on the hard disk . Hard disks can be divided into traditional PATA (Parallel Advanced Technology Attachment) hard disks and SATA (Se...

AI Technical Summary

Problems solved by technology

For example, there are up to 12 hard disks connected to the service system today. When the 12 hard disks are started at the same time, the total instantaneous peak current can be as high as 24A. At this time, the total instantaneous peak current value exceeds the setting of the overcurrent protection of the power supply device. value, causing the system to shut down (shutdown) and fail to complete the boot action

As mentioned above, when 12 hard disks are started at the same time, the total instantaneous peak current can be as high as 24A. Ordinary power supply devices cannot withstand such a large instantaneous peak current and are easily burned. Therefore, it is necessary to replace it with a special and expensive one. power supply unit, the cost will increase accordingly

[0004] In view of this, proposing a technology to control the sequential booting of hard disks to avoid problems such as system failure and power supply device burnout caused by multiple hard disks starting at the same time due to excessive power consumption has become a problem that the industry needs to overcome urgently.
