System for controlling hard disk sequential start

Abstract

The invention discloses a system for controlling hard disks to start sequentially, which is applied in an electronic system with at least a first group of hard disks and a second group of hard disks. The system mainly includes a power supply module, at least one processing module and at least one control module. The total power signal value (current signal value) generated by the system for controlling the sequential startup of hard disks in the present invention will not exceed the overcurrent protection value of the power module, which can ensure the normal startup of the system and avoid the simultaneous startup of the hard disks in the existing system. If the value exceeds the overcurrent protection value of the power supply device, the system cannot be started normally, the power supply device is burned, and the cost of replacing the dedicated power supply device is increased. The power signal can save power; the invention can also increase the number of processing modules according to the actual electrical design requirements to meet the increased demand of the system hard disk, thereby improving the design flexibility.

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...

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.
