Embodiment Construction

[0008] The principle of the present invention is to increase the electronic switch on the power supply circuit of each hard disk, whether the power supply of hard disk is controlled by the electronic switch conduction, use P channel MOS tube to realize electronic switch among the present invention; Realize the opening and closing of electronic switch in addition The switch signal is also required for closing, and the generation of the signal is composed of four modules: a clock module, a switch signal distribution module, a burr filter module and a switch signal isolation module. The clock module generates the clock and provides the reference clock to the switch signal distribution module, thereby generating the power switch signal required by each hard disk. After the switch signal passes through the burr filter module to eliminate the burr, it reaches the electronic switch through the switch signal isolation module, and then controls the electronic switch. Power on the hard d...

Abstract

The invention discloses a system and a method for reducing requirements on power supply power in a hard disk array system. The system mainly comprises a clock module, a switch signal distribution module, a burr filtering module, a switching signal isolation module and an electronic switch module which are connected sequentially, wherein the clock module generates a clock and provides a reference clock for the switch signal distribution module; the switch signal distribution module generates a power supply switching signal needed by each hard disk; the burr filtering module removes burr from the power supply switching signal which reaches the electronic switch through the switching signal isolation module and controls the electronic switch to open a hard disk power. The system and the method can eliminate the shock to the system power by simultaneous starting up of the hard disks in a disk array system with multiple hard disks, and evade the relation of hard disk starting power and system power supply power so as to greatly reduce the requirements on the power supply power. The components of the system are common logic components and separated components with low cost.

Description

technical field [0001] The invention relates to a hard disk array system, in particular to a system and method capable of effectively reducing the output power requirement of a system power supply in a hard disk video recorder, network storage server, and other hard disk array systems. Background technique [0002] At present, in a device or system that uses multiple hard disks to store data, all hard disks are started at the same time when the system is started; and the power of the hard disk is much smaller than the power of the hard disk when it is started. 40% to 50%. Therefore, in the conventional design, the total power of the system must meet the power requirements of all hard disks when starting up, which requires the selection of a higher-power power supply to meet the requirements for normal system startup. On the one hand, this will lead to waste of power supply, on the other hand, choosing a high-power power supply will greatly increase the cost, especially in d...
