Device, method and computer for managing power supply circuit of memory equipment

Abstract

The invention provides a device, a method and a computer for managing the power supply circuit of memory equipment; wherein, the device is used for managing the power supply for a backup disk in an independent redundant disk array in the computer and comprises a main control unit, a communication interface, a control circuit and a power control circuit; the main control unit is used for generating and transmitting a control command according to the preset control strategy, disk array configuration information and the alarm message from a disk array controller, the communication interface is connected with the main control unit and is used for receiving the control command, the control circuit is connected with the communication interface and is used for conveying the control command, and the power control circuit is connected with the control circuit and is used for regulating the power supply state of the backup disk in the independent redundant disk array according to the control command. The technology provided in the invention is used for carrying out effective control on the power-down and power-on of a hot backup disk which is taken as the backup disk, thereby remarkably reducing the power consumption of the hot backup disk in the idle state while realizing the protection of data, thus effectively lowering the total power consumption of the system.

Description

technical field [0001] The invention relates to computer system storage device management technology, in particular to a device, method and computer for managing a storage device power supply circuit. Background technique [0002] Computer systems, especially the server systems, are generally configured with Redundant Array of Independent Disks (RAID, Redundant Array of Independent Disks) in order to achieve fast orientation data and save data verification information. Advanced RAID configurations can combine multiple physical The disks are organized to form a virtual large-capacity logical disk. When a limited number of physical disks are damaged, the damaged data information can be recovered through the data verification information stored on other physical disks, so as to effectively maintain data security. [0003] In the prior art, the RAID5 array in the advanced RAID configuration can recover data completely when two disks are damaged at the same time; the RAID6 array ...

AI Technical Summary

Problems solved by technology

[0004] When the disk is working, it has a working power consumption (generally 20W), and when the disk is in the standby idle (IDLE) state, the standby power consumption is very small (generally 2.5W, that is, each HotSpare disk will consume 2.5W), If there are 100 servers in a computer room, and the RAID configuration of each server is 6+2, which conforms to the RAID5 standard, and 200 HotSpare disks are in the charged standby state, then the annual power consumption of all HotSpare disks is about 4380 kWh; It can be seen that the application of existing technologies will cause excessive power consumption of the entire computer system and increase power consumption.
