Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a method for creating RAID, an apparatus for creating RAID, an electronic device, and a readable storage medium. Background Technology

[0002] With the rapid development of technology, servers are being used more and more widely across various industries. Consequently, the demand for servers is increasing significantly, and consequently, the requirements for server operating systems are also rising. Currently, many customers require that the KOS operating system be pre-installed on their ordered servers so that they can use it to process data later.

[0003] KOS, a server operating system, supports multiple chip architectures and computing scenarios, including x86 and ARM, making it a server operating system for the intelligent computing era. Through hardware and software co-optimization, KOS-based applications in artificial intelligence, virtualization, and cloud-native computing have seen enhanced development efficiency, operational efficiency, and scalability. It effectively improves system maintainability and supports hot upgrades of the kernel and application software. KOS has become the preferred choice for industry users, making its promotion in the server field highly valuable.

[0004] However, before pre-installing the KOS operating system on the server, a RAID (Redundant Array of Independent Disks) needs to be created on the server, and then the KOS operating system is installed on the RAID.

[0005] RAID combines multiple relatively inexpensive hard drives into a single array using a RAID controller, enabling the array to achieve performance equal to or even exceeding that of a single, expensive, high-capacity hard drive. Depending on the chosen RAID level, RAID offers one or more advantages over a single hard drive, including enhanced data integration, improved fault tolerance, and increased processing power or capacity.

[0006] Servers sometimes come pre-installed with multiple RAID array cards, such as LSI or PMC cards, each paired with different disks. Therefore, before creating a RAID array, it's necessary to determine which RAID array card and its associated disks will be used. Once the target RAID array card and its associated disks are identified, the RAID array is then created based on these specifications.

[0007] Currently, when determining which RAID array card and its associated disk to create a RAID array, staff can manually specify the RAID array card and its associated disk on the server. However, as the number of servers requiring pre-installed KOS increases, the RAID array cards in each server are not entirely the same, and the disks associated with different RAID array cards in the same server are also not entirely the same. Therefore, manually specifying which RAID array card and its associated disk to create a RAID array on each server is labor-intensive, time-consuming, error-prone, and has high labor costs. Summary of the Invention

[0008] To address the aforementioned problems, this application provides a method for creating RAID, an apparatus for creating RAID, an electronic device, and a readable storage medium.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Before introducing the solution of this application, the technical terms that may be involved in this application will be explained.

[0036] KOS: A server operating system.

[0037] LSI RAID controller: Broadcom's RAID controller, commonly available in series such as 9440, 9460, and 9560.

[0038] PMC RAID card: Adaptec's RAID controller, commonly available in the market are the 8222, 8202 series cards, etc.

[0039] storcli64: A tool for LSI RAID cards used in the system OS. This tool can be used to implement different levels of RAID such as RAID1 and RAID0.

[0040] arcconf: A tool used by PMC RAID cards in the system OS, which can be used to implement different levels of RAID such as RAID1 and RAID0.

[0041] PXE: Pre-boot Execution Environment, is a protocol designed by Intel that allows a computer to download a boot image from a remote server over a network and load installation files or the entire operating system.

[0042] BOM is an abbreviation for Bill of Materials, commonly used in manufacturing, industrial design, and electronic device design. A BOM generally refers to a list that details the components of a product, including the quantity, specifications, and description of each part.

[0043] Reference Figure 1 The diagram illustrates a flowchart of a method for creating a RAID array according to an embodiment of the present invention, applied to a server. The method includes: In step S101, it is detected whether a first RAID card exists in the server, paired with only two disks. The two disks paired with the first RAID card are of the same type. The disk types include at least solid-state drives (SSDs) or hard disk drives (HDDs).

[0044] You can first detect the type of RAID card present on the server. The RAID card types include LSI RAID cards or PMC RAID cards.

[0045] For LSI RAID cards present on the server, the storcli64 tool can be used to retrieve relevant information about the LSI RAID card.

[0046] For example, the storcli64 tool can retrieve the type of RAID card present on the server (in this case, the type is LSI). The storcli64 tool can also retrieve the index number of the LSI RAID card (different RAID cards on the server have different index numbers), the model of the disk paired with the LSI RAID card, the number of disks paired with the LSI RAID card, the type of disk paired with the LSI RAID card (the disk type includes solid-state drives and hard disk drives, etc.), the capacity of the disk paired with the LSI RAID card, and whether the LSI RAID card is paired with only one type of disk (or whether the LSI RAID card is paired with only solid-state drives).

[0047] The retrieved information about the LSI array card can be represented by a data structure, for example, the data structure can be as follows: lsi=${i}|model=${model}|num=${num}|onlyincard=${only}|type=${type}|size=${size} LSI represents the type of RAID card. The part separated by "|" after "=" represents the following: LSI RAID card index number, the model of the disk that is paired with the LSI RAID card, the number of disks that are paired with the LSI RAID card, whether the LSI RAID card is paired with only one type of disk (or whether the LSI RAID card is paired with only solid-state drives), the type of disk that is paired with the LSI RAID card, and the capacity of the disk that is paired with the LSI RAID card.

[0048] For example, in one instance, there are two LSI array cards on the server.

[0049] The relevant information for the two LSI array cards retrieved using the storcli64 tool is shown below: lsi=0|model=MZ7L3480HCHQ-00B7C|num=2|onlyincard=0|type=SSD|size=446.625GB.

[0050] lsi=1|model=ST6000NM019B-2TG103|num=12|onlyincard=0|type=HDD|size=5.457TB.

[0051] For PMC RAID cards present on the server, the arcconf tool can be used to retrieve relevant information about the PMC RAID cards.

[0052] For example, the arcconf tool can retrieve the type of RAID card present on the server (in this case, the type is PMC). The arcconf tool can also retrieve the index number of the PMC RAID card (different RAID cards on the server have different index numbers), the model of the disk paired with the PMC RAID card, the number of disks paired with the PMC RAID card, the type of disks paired with the PMC RAID card (disk types include solid-state drives and hard disk drives, etc.), the capacity of the disks paired with the PMC RAID card, and whether the PMC RAID card is paired with only one type of disk (or whether the PMC RAID card is paired with only solid-state drives).

[0053] The retrieved information about the PMC RAID card can be represented by a data structure, for example, the data structure can be as follows: pmc=${i}|model=${model}|num=${num}|onlyincard=${only}|type=${type}|size=${size}.

[0054] PMC refers to the type of RAID card. The part separated by "|" after "=" represents the following: the index number of the PMC RAID card, the model of the disk that the PMC RAID card is paired with, the number of disks that the PMC RAID card is paired with, whether the PMC RAID card is paired with only one type of disk (or whether the PMC RAID card is paired with only solid-state drives), the type of disk that the PMC RAID card is paired with, and the capacity of the disk that the PMC RAID card is paired with.

[0055] For example, in one instance, there is a PMC array card on the server.

[0056] The following is the relevant information of a PMC RAID card retrieved using the arcconf tool: pmc=1|model=ST16000NM000J-2TW103|num=13|onlyincard=1|type=HDD|size=15259648MB.

[0057] If the LSI RAID card is paired with two disks in its information and the disks are of the same type (e.g., both are solid-state drives or both are hard disks), then this LSI RAID card can be identified as the first RAID card paired with only two disks.

[0058] Alternatively, if the PMC RAID card is paired with two disks in the relevant information of the PMC RAID card and the disks are of the same type (e.g., both are solid-state drives or both are hard disks), then this PMC RAID card can be identified as the first RAID card paired with only two disks.

[0059] In the case where a first RAID card exists in the server and is paired with only two disks, in step S102, RAID1 is created based on the first RAID card and the two disks paired with the first RAID card.

[0060] In one embodiment of this application, the server has one first RAID card that is paired with only two disks, and RAID1 can be created based on this one first RAID card and the two disks paired with this one first RAID card.

[0061] In another embodiment of this application, there are multiple first RAID cards in the server, each paired with only two disks. Thus, one first RAID card can be selected from among the multiple first RAID cards, and then RAID 1 can be created based on the selected first RAID card and the two disks paired with it.

[0062] The types of disks that can be paired with an RAID card include solid-state drives (SSDs) or hard disk drives (HDDs).

[0063] In this way, it is possible to detect whether there is a first RAID card with two solid-state drives among multiple first RAID cards.

[0064] In the information about the first LSI type RAID card, if the number of disks paired with the first LSI type RAID card is 2 and the type of disks is solid-state drives, it can be determined that this first LSI type RAID card is a first RAID card paired with two solid-state drives.

[0065] Alternatively, if the information about the first RAID card of type PMC shows that the number of disks it is paired with is 2 and the type of disks is solid-state drives (SSDs), then it can be determined that this first RAID card of type PMC is a first RAID card paired with two SSDs.

[0066] In the case of a RAID 1 array with two solid-state drives (SSDs) among multiple RAID 1 array cards, a RAID 1 array can be created based on the RAID 1 array with two SSDs and the two SSDs associated with the RAID 1 array with two SSDs.

[0067] For example, in one example, among multiple first array cards, a first array card with two solid-state drives is considered as one. Thus, RAID1 can be created based on this first array card with two solid-state drives and the two solid-state drives paired with this first array card.

[0068] Alternatively, in another example, among multiple RAID controllers, at least two RAID controllers are paired with two solid-state drives (SSDs). In this case, the RAID controller with the lowest total SSD capacity can be selected from these two RAID controllers. Then, a RAID 1 array is created based on the selected RAID controller and its paired SSDs. This minimizes the storage space occupied by creating the RAID 1 array, freeing up more storage space for other server tasks and improving storage utilization.

[0069] Alternatively, if there is no RAID card with two solid-state drives among the multiple RAID cards, it is possible to detect whether there is a RAID card with two mechanical hard drives among the multiple RAID cards.

[0070] If the information about the first LSI type RAID card shows that the first LSI type RAID card is paired with two disks, and both disks are mechanical hard drives, then it can be determined that this first LSI type RAID card is a first RAID card paired with two mechanical hard drives.

[0071] Alternatively, if the information about the first RAID card of type PMC shows that the number of disks it is paired with is 2 and the type of disks is mechanical hard drives, then it can be determined that this first RAID card of type PMC is a first RAID card paired with two mechanical hard drives.

[0072] In the case of a RAID 1 array where there is a RAID 1 array with two mechanical hard drives, a RAID 1 array can be created based on the RAID 1 array with two mechanical hard drives and the two mechanical hard drives paired with the RAID 1 array with two mechanical hard drives.

[0073] For example, in one example, among multiple first array cards, there is one first array card with two mechanical hard drives. In this way, RAID1 can be created based on this first array card with two mechanical hard drives and the two mechanical hard drives paired with this first array card.

[0074] Alternatively, in another example, among multiple RAID controllers, at least two are paired with two hard drives. In this case, the RAID controller with the lowest total capacity of its paired hard drives can be selected from these two options. Then, a RAID 1 array is created based on the selected RAID controller and its paired hard drives. This minimizes the storage space occupied by creating the RAID 1 array, allowing more storage space to be used for other server tasks, thus improving storage utilization.

[0075] In this application, RAID 1 is first created using a first RAID card with two solid-state drives and two solid-state drives paired with the first RAID card. If there is no first RAID card with two solid-state drives among the multiple first RAID cards, RAID 1 is then created using a first RAID card with two hard disk drives and two hard disk drives paired with the first RAID card. In this way, the RAID 1 created can be made to be on solid-state drives as much as possible. The performance of solid-state drives is often higher than that of hard disk drives. Thus, the performance of the created RAID 1 can be maximized, thereby improving the performance of the KOS system pre-installed on the created RAID 1.

[0076] In this application, the RAID levels include: RAID0, RAID1, RAID0+1, RAID1+0, RAID3, RAID4, RAID5 and RAID6. The most common are RAID0, RAID1 and RAID5. The number of disks required for each RAID level is different. For example, RAID0 can be created using 1 disk, RAID1 can be created using 2 disks, and RAID6 can be created using 3 or 4 disks.

[0077] If there is no first RAID card in the server that is paired with only two disks, in step S103, it is detected whether there is a second RAID card in the server that is paired with only one disk.

[0078] If the number of disks paired with the LSI RAID card in the relevant information of the LSI RAID card is 1, it can be determined that this LSI RAID card is a second RAID card paired with only one disk.

[0079] Alternatively, if the number of disks paired with the PMC RAID card is 1 in the relevant information of the PMC RAID card, it can be determined that this PMC RAID card is a second RAID card paired with only one disk.

[0080] In step S104, if a second RAID card exists in the server and is paired with only one disk, RAID0 is created based on the second RAID card and the disk paired with the second RAID card.

[0081] In one embodiment of this application, if there is only one second RAID card in the server that is paired with one and only one disk, then RAID0 can be created based on this one second RAID card and the disk paired with this one second RAID card.

[0082] In another embodiment of this application, the server may have multiple second RAID cards paired with one disk. Thus, one second RAID card can be selected from among the multiple second RAID cards, and then a RAID 0 array can be created based on the selected second RAID card and the two disks paired with it.

[0083] The types of disks that can be paired with an RAID card include solid-state drives (SSDs) or hard disk drives (HDDs).

[0084] In this way, it is possible to detect whether there is a second RAID card with a solid-state drive among multiple second RAID cards.

[0085] In the information about the LSI type second RAID card, if the number of disks paired with the LSI type second RAID card is 1 and the type of disk is solid-state drive, it can be determined that this LSI type second RAID card is a second RAID card paired with one solid-state drive.

[0086] Alternatively, if the information about the PMC type second RAID card indicates that the number of disks paired with the PMC type second RAID card is 1 and the type of disk is a solid-state drive (SSD), then it can be determined that this PMC type second RAID card is a second RAID card paired with a single SSD.

[0087] In the case of a second RAID card with a solid-state drive (SSD) among multiple second RAID cards, a RAID 0 array can be created based on the second RAID card with a SSD and the SSD associated with the second RAID card with a SSD.

[0088] For example, in one example, among multiple second RAID cards, there is one second RAID card paired with a solid-state drive. In this way, RAID0 can be created based on this second RAID card paired with a solid-state drive and the solid-state drive paired with this second RAID card.

[0089] Alternatively, in another example, among multiple secondary RAID controllers, at least two are paired with a single solid-state drive (SSD). In this case, the RAID 0 array can be created by selecting the secondary RAID controller with the lowest SSD capacity from the at least two paired with one SSD, and then using the selected secondary RAID controller and its paired SSD. This minimizes the storage space occupied by creating the RAID 0 array, freeing up more storage space for other server tasks and improving storage utilization.

[0090] Alternatively, if there is no second RAID card with a solid-state drive among the multiple second RAID cards, it is possible to detect whether there is a second RAID card with a mechanical hard drive among the multiple second RAID cards.

[0091] In the information about the LSI type second RAID card, if the number of disks paired with the LSI type second RAID card is 1 and the type of disk is a mechanical hard drive, it can be determined that this LSI type second RAID card is a second RAID card paired with one mechanical hard drive.

[0092] Furthermore, if the number of disks paired with the PMC type second RAID card is 1 and the type of disk is a mechanical hard drive, then it can be determined that this PMC type second RAID card is a second RAID card paired with one mechanical hard drive.

[0093] When there is a second RAID card with a mechanical hard drive among multiple second RAID cards, RAID 0 can be created based on the second RAID card with a mechanical hard drive and the mechanical hard drive paired with the second RAID card with a mechanical hard drive.

[0094] For example, in one example, among multiple second RAID cards, there is one second RAID card paired with a mechanical hard drive. In this way, RAID0 can be created based on this second RAID card paired with a mechanical hard drive and the mechanical hard drive paired with this second RAID card.

[0095] Alternatively, in another example, among multiple first RAID cards, there are at least two second RAID cards paired with a single mechanical hard drive. This allows selecting the second RAID card with the lowest-capacity mechanical hard drive from among the at least two paired cards. Then, a RAID 0 array is created based on the selected second RAID card and its paired mechanical hard drive. This minimizes the storage space occupied by creating the RAID 0 array, freeing up more storage space for other server tasks and improving storage utilization.

[0096] In this application, RAID 0 is first created using a second RAID card with a solid-state drive (SSD) and a SSD paired with the second RAID card. If no second RAID card with an SSD is available, RAID 0 is then created using a second RAID card with a hard disk drive (HDD) and a HDD paired with the second RAID card. This maximizes the performance of the created RAID 0 on the SSD, which typically outperforms HDDs. This approach aims to improve the performance of the created RAID 0 and, consequently, the performance of the KOS system pre-installed on the created RAID 0.

[0097] If there is no second RAID card in the server and it is only equipped with one disk, in step S105, it is detected whether there is a third RAID card in the server equipped with three or more disks.

[0098] If the number of disks paired with the LSI RAID card is 3 or more in the relevant information of the LSI RAID card, it can be determined that this LSI RAID card is a third RAID card paired with three or more disks.

[0099] Alternatively, if the number of disks paired with the PMC RAID card is 3 or more in the relevant information of the PMC RAID card, it can be determined that this PMC RAID card is a third RAID card paired with three or more disks.

[0100] In the case where there is a third RAID card in the server with three or more disks, in step S106, RAID1 is created based on the third RAID card and two disks of the same type from the three or more disks that are paired with the third RAID card.

[0101] In one embodiment of this application, a third RAID card in a server is configured with three or more disks, and at least two of the disks are of the same type. RAID 1 can then be created based on this third RAID card and two of the three or more disks configured with this third RAID card that are of the same type.

[0102] In one embodiment of this application, there are multiple third RAID cards in the server, each equipped with three or more disks, and at least two of the disks are of the same type. A third RAID card can be selected from among the multiple third RAID cards, and then RAID1 can be created based on the selected third RAID card and two of the three or more disks of the same type that are equipped with the selected third RAID card.

[0103] The types of disks that can be paired with an RAID card include solid-state drives (SSDs) or hard disk drives (HDDs).

[0104] In this way, it is possible to detect whether there is a third RAID card among multiple third RAID cards that is paired with disks including two solid-state drives.

[0105] In the case where the number of disks paired with the LSI-type third RAID card is 3 or more and the type of disks is solid-state drive (SSD) in the relevant information of the LSI-type third RAID card, it can be determined that this LSI-type third RAID card is a third RAID card with two SSDs as its paired disks.

[0106] Alternatively, if the number of disks paired with the PMC type third RAID card in the relevant information of the PMC type third RAID card is 3 or more and the type of disks paired with it is solid-state drives, it can be determined that this PMC type third RAID card is a third RAID card with two solid-state drives paired with it.

[0107] In the case of multiple third-array cards, there are third-array cards with two solid-state drives (SSDs) as their paired disks. RAID 1 can be created based on the third-array card with two SSDs as its paired disks and the two SSDs paired with the third-array card with two SSDs as its paired disks.

[0108] For example, in one instance, among multiple third-array cards, one third-array card is configured with two solid-state drives (SSDs). Thus, RAID 1 can be created using this single third-array card with two SSDs and the two SSDs associated with this single third-array card.

[0109] Alternatively, in another example, among multiple third-array cards, at least two of them are paired with disks including two SSDs. In this case, the third-array card with the lowest total capacity of the two SSDs can be selected from the at least two paired third-array cards. Then, RAID 1 is created based on the selected third-array card and the two SSDs paired with it. This minimizes the storage space occupied by creating the RAID 1 array, freeing up more storage space for other server tasks and improving storage utilization.

[0110] Alternatively, if there is no matching disk among the multiple third RAID cards that includes two solid-state drives, it is possible to detect whether there is a matching disk among the multiple third RAID cards that includes two mechanical hard drives.

[0111] In the information about LSI-type third RAID cards, if the number of disks paired with the LSI-type third RAID card is 3 or more and the type of disks paired with it is mechanical hard disk, it can be determined that this LSI-type third RAID card is a third RAID card paired with two mechanical hard disks.

[0112] Alternatively, if the information about the PMC type third RAID card indicates that the number of disks paired with the PMC type third RAID card is 3 or more and the type of disks paired with it is mechanical hard drives, then it can be determined that this PMC type third RAID card is a third RAID card with two mechanical hard drives paired with it.

[0113] In the case of multiple third-array cards, there are third-array cards with two mechanical hard drives as their paired disks. RAID 1 can be created based on the third-array card with two mechanical hard drives as its paired disks and the two mechanical hard drives paired with the third-array card with two mechanical hard drives.

[0114] For example, in one example, among multiple third-array cards, one third-array card is paired with two mechanical hard drives. Thus, RAID1 can be created based on this third-array card paired with two mechanical hard drives and the two mechanical hard drives paired with this third-array card.

[0115] Alternatively, in another example, among multiple third-array cards, at least two of them consist of two mechanical hard drives. In this case, the third-array card with the lowest total capacity of the two mechanical hard drives can be selected from the at least two paired third-array cards. Then, RAID 1 is created based on the selected third-array card and the two mechanical hard drives paired with it. This minimizes the storage space occupied by creating RAID 1, allowing more storage space to be used for other server tasks, thus improving storage utilization.

[0116] In this application, RAID 1 is preferentially created based on a third RAID card with two solid-state drives (SSDs) and the two SSDs associated with that third RAID card. If no third RAID card with two SSDs is available, RAID 1 is created based on a third RAID card with two hard disk drives (HDDs) and the two HDDs associated with that third RAID card. This maximizes the performance of the created RAID 1 array on SSDs, which generally outperform HDDs, thus improving the performance of the RAID 1 array and consequently enhancing the performance of the KOS system pre-installed on the created RAID 1 array.

[0117] In summary, the order in which the array card and the disks paired with the array card are selected for creating a RAID array in this application can be as follows: Figure 2 As shown.

[0118] Secondly, before creating a RAID array, this application determines the following data: the type of RAID card, its index number, and the model of the disks paired with it. Based on the RAID card type and index number, the RAID card used for RAID creation can be identified; based on the model of the disks paired with it, the disks used for RAID creation can be identified. Thus, a RAID array can be created based on the identified RAID card and its paired disks.

[0119] After determining the RAID card and the disks paired with it, the specific method for creating the RAID can be found in existing methods, and this application does not limit it. The focus of this application is to determine the RAID card and disks used to create the RAID.

[0120] The solution in this application is also applicable to situations where "one or more LSI RAID cards exist" in the server, or "one or more PMC RAID cards exist", or "one or more LSI RAID cards and one or more PMC RAID cards are mixed together".

[0121] After creating a RAID array, the KOS operating system can be automatically installed on the RAID array.

[0122] This application enables fully automated determination of which RAID array card and its associated disk to create the RAID array, eliminating the need for human intervention. This reduces manual workload and labor costs. Furthermore, the elimination of human intervention overcomes the possibility of human error, thereby improving the accuracy and efficiency of the determination process.

[0123] Secondly, a unified determination method is used for all batches of servers that need to be shipped. The granularity of the determination method is all servers, not just the batch of production servers. Different determination methods do not need to be set for different batches of servers. The number of determination methods that need to be set is small. Thus, the workload required to set the determination method is low and the method is highly universal.
