As an optional implementation, the disk array may be a disk array in a storage device, and the module that consumes more power in the storage device includes: the system comprises a main control unit, a disk array and a fan set. Where the power consumption of the disk array is relatively high. Fig. 3 is a schematic structural diagram of a storage device according to an alternative embodiment of the present invention, where a power supply module is used to provide power for a main control unit, a hard disk, and a switch, a disk array includes a plurality of disks, and the number of the disks specifically included is determined according to an actual situation.

The current for starting the hard disk is larger and is generally 2-3 times of the working current. If the requirement that the disks in the disk array are powered on simultaneously is met, the requirement on the power module is high. Such a large current is not required for normal operation after the memory device is started, thereby causing power waste. In the implementation, a power supply module with a conventional specification can be selected, the disk array is powered on in a time-sharing mode at a fixed time interval during starting, and starting current is staggered. Specifically, the disks can be divided into different starting levels according to the state information of the disks in the disk array, and the disks in the disk array are started in a time-sharing manner according to the starting levels, so that the problem that the starting speed of the disk array is slow due to high current requirements when the disks in the disk array are started simultaneously can be solved, and the technical effect of improving the starting efficiency of the disk array can be achieved.

As an alternative embodiment, after the storage device is started, the data in the disk may be read or written to the disk. If the storage device is suddenly powered off or powered up, the storage device does not know which disk in the disk array to perform read or write operation before being restarted. In this case, the reading or writing operation needs to be performed again, which is tedious and time-consuming. To prevent this, the level of the disk that performs a read or write operation before the storage device crash may be set to the highest boot level in this embodiment. After the storage device is booted, the disk that performed the read or write operation before the booter is first started, so that the read or write operation that was not completed before the booter can be continuously performed. The problem of low efficiency caused by the fact that reading operation needs to be carried out again after the storage device is restarted is solved, and the technical effect of improving the efficiency of reading data or writing data can be achieved.
As an optional implementation manner, the boot level may be set according to the size of the storage space remaining in the disk, and the boot level set for the disk with more data is higher, that is, the disk with the remaining storage space less than or equal to the first threshold is set as the second boot level, where the first threshold may be determined according to actual situations, and may be, for example, 10G, 1G, 500M, and the like. And setting the grades of other disks in the disk array except the first boot grade and the second boot grade as a third boot grade.

After the first disk is started, starting a second disk of a second starting level, and similarly, disks in the disk array which meet that the remaining storage space is smaller than or equal to the first threshold value are collectively referred to as second disks, and the number of the second disks may be one or multiple. And starting other disks in the disk array after the second disk of the second starting level is started. In this embodiment, by performing time-sharing startup on the disks in the disk array, the problem of low startup efficiency can be avoided, and the effect of improving the disk startup efficiency is achieved.

As an optional implementation manner, after the storage device is started, after the main control unit is started, the disk operated in the last disk array is firstly queried from the system log or the maintenance data table, and the fan in the corresponding physical fan area is analyzed and identified, and the two are used as the first starting stage. And informs the control unit to start the first starting-stage magnetic disk and the fan first.

And dividing the disk starting grades in the disk array according to the data requests. After the disk in the disk array is started, reading or writing data can be executed through the communication connection between the main control unit and the disk. For example, if the data is read, the read data request carries data information requested to be read, and the disk storing the data sends the data to the main control unit. If the data is written, the data writing request carries the data requested to be written, and the data can be written into the corresponding disk through the communication connection between the main control unit and the disk.
