Abstract
Provided is a hard disk peak shift starting system, including: a power supply unit, a mainboard and a hard disk backplane. The power supply unit provides power to hard disks via a first power connector, a second power connector, E-Fuse chips and hard disk connectors. A Complex Programmable Logic Device (CPLD) unit sets a power-up starting sequence of the hard disks and a power-up starting time interval between the hard disks, and the CPLD unit is connected to a logical control end of each of the E-Fuse chips to control, based on the set power-up starting sequence and the set power-up starting time interval, on-off of a power supply end of each of the E-Fuse chips, to realize control of peak shift powering up and starting of the hard disks.
Claims8
A hard disk peak shift starting system, comprising:
- a mainboard comprising a Complex Programmable Logic Device (CPLD) unit, a first enable signal connector and a first power connector;
- a hard disk backplane comprising a plurality of hard disks, a second enable signal connector, a second power connector, E-Fuse chips and hard disk connectors, wherein the number of the E-Fuse chips and the number of the hard disk connectors are same as the number of the hard disks, the E-Fuse chip is connected to the hard disk via the hard disk connector, and the E-Fuse chip comprises a logical control end and a power supply end;
- and
- a power supply unit connected to an input end of the first power connector, wherein an output end of the first power connector is connected to an input end of the second power connector, and an output end of the second power connector is connected to the power supply end of each of the E-Fuse chips, wherein
- the power supply unit is configured to provide power to the hard disks via the first power connector, the second power connector, the E-Fuse chips and the hard disk connectors;
- the CPLD unit is connected to an input end of the second enable signal connector via the first enable signal connector, and an output end of the second enable signal connector is connected to the logical control end of each of the E-Fuse chips;
- and
- the CPLD unit is configured to set a power-up starting sequence of the hard disks and a power-up starting time interval between the hard disks, and the CPLD unit is connected to the logical control end of each of the E-Fuse chips to control, based on the set power-up starting sequence and the set power-up starting time interval, on-off of the power supply end of each of the E-Fuse chips, to realize control of peak shift powering up and starting of the hard disks.
