Embodiment Construction

[0015] refer to figure 1 Shown is a schematic diagram of the operating environment of a preferred embodiment of the system for reducing the startup current of the storage system according to the present invention. The system 10 for reducing the startup current of a storage system runs in a data processing device 11 . The storage system 12 includes a plurality of expanders 13 and storage devices 14 . The data processing device 11 is connected with an expander 13 and a power supply 15 . Each expander 13 is connected to multiple storage devices 14 . The storage 14 may be a SAS (Serial Attached SCSI, Serial Attached SCSI) hard disk or a SATA (Serial Advanced Technology Attachment, Serial ATA) hard disk. The expander 13 includes a storage area 16 (such as a flash memory) in which the startup time of the memory 14 is stored.

Abstract

The invention relates to a system for reducing starting current of a storage system. The storage system comprises a plurality of expanders and storages. The system comprises a detection module used for detecting the current of each storage provided by a power supplier when the storage system is started and calculating power of each storage according to the current of each storage; a determination module used for determining whether the power of the storage system is larger than a designated value or not according to the power of each storage; a shutdown module used for shutting down the storage system when the power of the storage system is larger than the designated value; a calculation module used for arranging a starting sequence according to the powder of each storage and calculating the starting time of each storage; and a storage module used for storing the starting time of each storage to a storage area of the expanders. The invention also provides a method for reducing the starting current of the storage system. With the system and the method provided by the invention, the starting current of the storage system can be reduced, and the situation that the storage system can not be started or even damaged due to power shortage can be prevented.

Description

technical field [0001] The invention relates to a system and method for controlling a storage system, in particular to a system and method for reducing the starting current of the storage system. Background technique [0002] As data storage requirements increase, more and more storage devices (such as hard disks) are included in a storage system (such as a disk array). When the storage system is started, if too many storage devices are started at the same time, the starting current of the storage system is too large. At this time, if the power supply of the power supply is insufficient, the storage system will not start normally or even be damaged. Using a high-power power supply can solve the problem of insufficient power supply. However, using a high-power power supply will increase system cost and power consumption. Contents of the invention [0003] In view of the above, it is necessary to provide a system for reducing the startup current of the storage system, whi...
