Further, the disk array 102 that does not have an open interface but can communicate with the expansion module through a protocol may be divided into multiple types, if the disk array is NVME, the initialization management device 101 directly communicates with the PSX of the expansion module 103, so as to send the initialization management instruction to the expansion module 103, and if the disk array is SAS, the initialization management device 101 directly communicates with the operating system of the expansion module 103.
In the invention, if the disk array type is not provided with an open interface but can communicate with the expansion module through a protocol, the initialization management device 101 adopts an out-of-band management mode to send an initialization management instruction to the expansion module 103, and the expansion module 103 sends an initialization management command to the disk array 102, and the whole system 104 is not required to complete the initialization task through initialization IO, so that the CPU resources and the back-end bandwidth are not required to be occupied, and the problem of overlong initialization time caused by the background execution of the initialization task is also avoided.
In a preferred embodiment, the method further comprises:

More specific examples of the computer readable storage medium may include, but are not limited to: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In embodiments of the invention, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. In embodiments of the present invention, however, a computer readable signal medium may comprise a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: electrical wires, optical cables, RF (Radio Frequency), etc., or any suitable combination of the foregoing.
The computer readable medium may be embodied in the server; or may exist separately and not be assembled into the server. The computer readable medium carries one or more programs which, when executed by the server, cause the server to: when the peripheral mode of the terminal is detected to be not activated, acquiring a frame rate of an application on the terminal; when the frame rate meets the screen information condition, judging whether a user is acquiring the screen information of the terminal; and controlling the screen to enter an immediate dimming mode in response to the judgment result that the user does not acquire the screen information of the terminal.
Computer program code for carrying out operations for embodiments of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C + + or the like and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any type of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet service provider).

In particular, the system or system embodiments are substantially similar to the method embodiments and therefore are described in a relatively simple manner, and reference may be made to some of the descriptions of the method embodiments for related points. The above-described system and system embodiments are only illustrative, wherein the units described as separate parts may or may not be physically separate, and the parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.
The initialization method, device, electronic device and computer storage medium of the disk array provided by the invention are introduced in detail, and a specific example is applied in the text to explain the principle and the implementation of the invention, and the description of the above embodiment is only used to help understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.

acquiring the disk array type of the disk array;
and if the disk array type is a preset disk array type, sending an initialization command to the disk array to complete the initialization task.
2. The method according to claim 1, wherein the preset disk array type is an open interface, and the sending of the initialization command to the disk array to complete the initialization task comprises:
and sending a zero setting command to the disk array to complete the initialization task.
3. The method according to claim 1, wherein the preset disk array type is not provided with an open interface but can communicate with an expansion module through a protocol, and the sending an initialization command to the disk array to complete the initialization task comprises:
and sending an initialization management instruction to an expansion module connected with the disk array so as to enable the expansion module to issue the initialization command to the disk array through a protocol.
4. The method according to any one of claims 1 to 3, further comprising:
if the disk array type is not the preset disk array type, issuing an initialization task notification to the whole machine system so that the whole machine system calls initialization input/output to complete the initialization task.
5. The method of claim 4, further comprising:
receiving the predicted load degree of the front-end service input/output sent by the whole machine system in real time;
determining the target load degree of the initialization input/output according to the predicted load degree;
and sending a load degree adjusting instruction containing the target load degree to the whole machine system, so that the whole machine system adjusts the current load degree of the initialization input/output to the target load degree after receiving the load degree adjusting instruction.
6. The method of claim 5, wherein determining the target load level for the initialization input/output based on the predicted load level further comprises:
if the predicted load degree is larger than a predicted threshold value, the target load degree is smaller than or equal to a first load degree threshold value;
