[0041] Embodiment 1

[0042] Figure 1 The present invention provides a method for dynamically adjusting disk loads, and the method includes at least the following steps:

[0043] Step S101, in response to a disk load dynamic adjustment request, obtaining an initial disk capacity of any disk;

[0044] Step S102, based on the initial disk capacity of the disk and according to a preset disk weight allocation rule, determining the optimal capacity ratio of the disk;

[0045] Step S103, in response to the data write request, writing the data to the target disk according to the optimal capacity ratio to achieve dynamic adjustment of the disk load.

[0046] In one embodiment, based on the initial disk capacity of the disk, the optimal capacity ratio of the disk is determined according to a preset disk weight allocation rule, including: determining the initial capacity ratio of the disk based on the initial disk capacity of the disk; and rounding the least common multiple of the initial capacity ratio to determine the optimal capacity ratio of the disk.

[0047] Specifically, when there are three disks, the disk capacities of the three disks are 13T, 15T, and 7T respectively, and the initial capacity ratio is determined to be 13:15:7; according to the initial capacity ratio and the disk weight allocation rule, the optimal capacity ratio of the three disks is determined to be 7:8:4. Among them, the disk weight allocation rule is to take the lowest common multiple of the initial capacity ratio.

[0048] In one embodiment, based on the initial disk capacity of the disk and in accordance with a preset disk weight allocation rule, the optimal capacity ratio of the disk is determined, including: obtaining the disk traffic limit of the disk and determining the disk traffic ratio of the disk; based on the initial disk capacity of the disk, obtaining the initial capacity ratio of the disk; and determining the optimal capacity ratio of the disk based on the disk traffic ratio of the disk and the initial capacity ratio of the disk.

[0049] In one embodiment, in response to a data write request, data is written to the target disk according to the optimal capacity ratio, including: in response to the data write request, obtaining the remaining disk capacity of the disk; based on the remaining capacity of the disk, updating the optimal capacity ratio of the disk according to a preset disk weight update rule; writing data to the target disk based on the updated optimal capacity ratio to achieve dynamic adjustment of the disk load.

[0050] In one embodiment, based on the remaining capacity of the disk, the optimal capacity ratio of the disk is updated according to the preset disk weight update rule, including: obtaining the remaining capacity ratio of any two of the disks; if the remaining capacity ratio of any two of the disks is greater than a preset value, updating the optimal capacity ratio of the disk according to the preset disk weight allocation rule.

[0051] Specifically, when it is necessary to adjust the disk capacity or adjust the bandwidth of different machines, such as when the disk capacity of the disk is only half and the amount of data written to this disk needs to be reduced, the capacity ratio can be set to 1:2 according to the specific usage. If the load of the disk cluster (i.e., a disk containing at least two disks) is very high, the capacity ratio of 1:2 may cause pressure on the large-capacity disk. Then the capacity ratio can be modified to 3:5, 4:7, etc. according to the actual usage. The reason for the need for modification is that when the capacity ratio is determined in this application, the disk capacity unit of the disk is T. Therefore, when the ratio between the two disks is still very different, the storage pressure on the large-capacity disk will increase.

[0052] In one embodiment, after determining the optimal capacity ratio of the disk based on the initial disk capacity of the disk and in accordance with a preset disk weight allocation rule, the method further includes: based on the optimal capacity ratio of the disk, expanding the capacity of each disk and generating a disk list; wherein there is at least one target disk in the disk list.

[0053] Specifically, three disks (Disk1, Disk2, Disk3) with capacities of 13T, 15T, and 7T are used as an example for explanation; Figure 2As shown in the figure, the disk capacities of Disk1, Disk2, and Disk3 are 13T, 15T, and 7T respectively, so the initial capacity ratio of Disk1:Disk2:Disk3 is determined to be 13:15:7; according to the initial capacity ratio and the disk weight allocation rule, the optimal capacity ratio of Disk1:Disk2:Disk3 is determined to be 7:8:4; based on the optimal capacity ratio of Disk1, Disk2, and Disk3, Disk1, Disk2, and Disk3 are expanded respectively, and the following is generated: 1, disk12, disk13, disk14, disk15, disk16, disk17, disk21, disk22, disk23, disk24, disk25, disk26, disk27, disk28, disk31, disk32, disk33, disk34]; select the target disk based on the generated disk list, and determine that at least one of disk11-disk34 is the target disk. Disk11-disk17 is the expansion result of the disk (Disk1) with a disk capacity of 13T; disk21-disk28 is the expansion result of the disk (Disk2) with a disk capacity of 15T; disk31-disk34 is the expansion result of the disk (Disk3) with a disk capacity of 7T.

[0054] In one embodiment, if Figure 2 As shown, the disk load dynamic adjustment method described in the present application is applied to a disk load dynamic adjustment device, which includes a configuration center, and the initial capacity ratio, optimal capacity ratio and usage status of any disk are stored in the configuration center; when the optimal capacity ratio needs to be modified, the configuration can be modified directly in the configuration center to achieve automatic adjustment of the disk capacity ratio.

[0055] Specifically, all disk capacity ratios in this application are stored in the configuration center, and the optimal capacity ratio of the disks in the configuration center can be manually / automatically modified. In this way, only one modification is needed to make the entire disk load dynamic adjustment system automatically sensed, so as to realize the automatic monitoring of the (optimal) capacity ratio of the disk. It should be understood that the configuration center described in this application is a unit of the same management configuration, and can perceive the changes of the system configuration (such as the optimal capacity ratio of the disk) in real time during its operation.
