Description

Method, device, equipment and medium for creating RAID

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method for creating a RAID, an apparatus for creating a RAID, an electronic device, and a readable storage medium.

Background

With the rapid development of technology, the server is applied more and more widely in various industries, so that the demands of various industries on the server are gradually increased, and secondly, the demands of various industries on the operating system of the server are increased along with the water fluctuation. Currently, many clients require the KOS operating system to be preloaded in their intended servers so that the KOS operating system in the server can be used later to process data.

The KOS operating system supports various chip architectures and computing scenes such as x86, ARM and the like, and is a server operating system oriented to the intelligent computing age. Through the soft and hard collaborative optimization, the artificial intelligence, the virtualization, the cloud native and other applications based on the KOS are enhanced in the aspects of development efficiency, operation efficiency, expansibility and the like. The maintainability of the system can be effectively improved, the hot upgrading of the kernel and the application software and the like are supported, and the KOS becomes the first choice of industry users, so that the popularization of the KOS operating system in the field of servers has high value.

However, it is necessary to create a RAID (Redundant Array of Independent Disks, redundant array of disks) in the server before the KOS operating system is preloaded on the server, and then install the KOS operating system on the RAID.

RAID combines a plurality of relatively cheap hard disks through RAID array cards to form a hard disk array group, so that the performance of the hard disk array group reaches or exceeds that of an expensive and huge-capacity hard disk. Depending on the level selected, RAID has one or more of the following benefits over a single hard disk: enhancing data integration, enhancing fault tolerance, increasing throughput or capacity, etc.

In some cases, the server is preloaded with a plurality of RAID array cards, including LSI array cards and PMC array cards, and different disks are mounted on each array card, so that it is necessary to determine which RAID array card and which disk it is collocated on to create a RAID before creating a RAID. At the position ofDetermining that a target RAID array card is needed and determining that the target RAID array card is needed Matched target magnetic disk woundUnder the condition of establishing RAID, establishing RAID according to the target RAID array card and the target disk collocated with the target RAID array card.

At present, when determining which RAID array card and which disk to be matched with the RAID array card are created, a worker can manually specify which RAID array card in a server and which disk to be matched with the RAID array card on site, but as the number of servers needing to be preloaded with KOS is increased, the array cards in each server are not identical, and the disks matched with different array cards in the same server are not identical, so that the workload of manually specifying which RAID array card in each server and which disk to be matched with the RAID array card on site by the worker is large, the time consumption is long, the error is easy, and the labor cost is high.

Prior to the description of the solution of the present application, technical terms that may be related to the present application will be explained.

KOS: an operating system for a server.

LSI array card: RAID controllers from Broadcom are commercially available in the series of cards 9440, 9460, 9560, etc.

PMC array card: RAID controllers of Adaptec company are commonly used in the market, such as 8222, 8202 series cards.

arccon f: the PMC array card is applied under the system OS, and RAID of different levels such as RAID1, RAID0 and the like can be realized through the tool.

PXE: pre-boot Execution Environment, a protocol designed by Intel, allows a computer to download a boot image from a remote server over a network and load an installation file or the entire operating system.

BOM: bill of Materials (bill of materials) is commonly used in the fields of manufacturing, industrial design, electronic device design, and the like. BOM generally refers to a list of components of a product and information about the number, specifications, descriptions, etc. of each component.

Referring to fig. 1, a flowchart illustrating steps of a method for creating RAID according to an embodiment of the present invention is applied to a server, where the method includes:

in step S101, it is detected whether there is a first array card collocated in the server and only two disks are collocated. The two disks collocated by the first array card are of the same type. The type of magnetic disk at least comprises a solid state disk or a mechanical disk.

The type of array card present on the server may be detected first, and the type of array card includes an LSI array card or a PMC array card.

For LSI array cards present on the server, the relevant information for LSI array cards can be called up using the garcili 64 tool.

For example, the type of the array card existing on the server (the type at this time is LSI) may be called by using the garcili 64 tool, and the index number of the LSI array card (the index numbers of different array cards existing on the server are different) may be called by using the garcili 64 tool, the type of the magnetic disk collocated with the LSI array card, the number of magnetic disks collocated with the LSI array card, the type of the magnetic disk collocated with the LSI array card (the type of the magnetic disk includes solid state disk, mechanical hard disk, etc.), the capacity of the magnetic disk collocated with the LSI array card, and whether the LSI array card is collocated with only one type of magnetic disk (or whether the LSI array card is collocated with only solid state disk).

The retrieved information about the LSI array card may be embodied in a data structure, for example, the data structure may be as follows:

lsi＝${i}|model＝${model}|num＝${num}|onlyincard＝${only}|type＝${type}|size＝${size}

lsi is the type of array card, and the parts separated by "=" behind "|" are respectively represented by: the index number of the LSI array card, the type of the disk in which the LSI array card is paired, the number of the disks in which the LSI array card is paired, whether the LSI array card is paired with only one type of disk (or whether the LSI array card is paired with only a solid state disk), the type of the disk in which the LSI array card is paired, and the capacity of the disk in which the LSI array card is paired.

For example, in one example, there are two LSI array cards on the server.

The information about two LSI array cards called using the garcali 64 tool is as follows:

for PMC array cards present on a server, the arcconf tool may be used to retrieve information about the PMC array card.

For example, the arcconf tool may be used to retrieve the type of array card that exists on the server (where the type is PMC), the arcconf tool may also be used to retrieve the index number of the PMC array card (where the index numbers of different array cards that exist on the server are different), the type of disk that the PMC array card mates with, the number of disks that the PMC array card mates with, the type of disk that the PMC array card mates with (the type of disk includes solid state disk and mechanical disk, etc.), the capacity of the disk that the PMC array card mates with, and whether the PMC array card mates with only one type of disk (or whether the PMC array card mates with only solid state disk).

The relevant information of the retrieved PMC array card may be embodied in a data structure, for example, the data structure may be as follows:

pmc＝${i}|model＝${model}|num＝${num}|onlyincard＝${only}|type＝${type}|size＝${size}。

pmc is the type of array card, and the parts separated by "=" behind "|" represent the meanings of: the index serial number of the PMC array card, the type of the matched magnetic disk of the PMC array card, the number of the matched magnetic disks of the PMC array card, whether the PMC array card is matched with only one type of magnetic disk (or whether the PMC array card is matched with only a solid state disk), the type of the matched magnetic disk of the PMC array card and the capacity of the matched magnetic disk of the PMC array card.

For example, in one example, there is one PMC array card on the server.

The relevant information for one PMC array card called using arcconf tool is as follows:

when the number of matched magnetic disks of the LSI array card in the related information of the LSI array card is 2 and the types of the matched magnetic disks are the same (for example, both are solid-state hard disks or both are mechanical hard disks, etc.), the LSI array card may be determined to be the first array card matched and only two magnetic disks are matched.

Or, in the case that the number of matched magnetic disks of the PMC array card in the related information of the PMC array card is 2 and the types of the matched magnetic disks are the same (for example, both are solid state hard disks or both are mechanical hard disks, etc.), it may be determined that the PMC array card is the first array card matched and only matches two magnetic disks.

In the case that there is a first array card collocated in the server and only two disks are collocated, in step S102, RAID1 is created according to the first array card and the two disks collocated by the first array card.

In one embodiment of the present application, the first array card collocated in the server and only collocated with two disks is one, so that RAID1 can be created according to the one first array card and the two disks collocated with the one first array card.

In another embodiment of the present application, the first array card collocated in the server and collocated with only two disks is plural. Thus, one first array card may be selected among the plurality of first array cards, and RAID1 may then be created from the selected one first array card and the two disks collocated with the selected one first array card.

The type of the magnetic disk matched with the array card comprises a solid state disk or a mechanical hard disk and the like.

Therefore, whether the first array cards matched with the two solid state disks exist in the plurality of first array cards can be detected.

When the number of matched magnetic disks of the LSI type first array card in the related information of the LSI type first array card is 2 and the types of matched magnetic disks are all solid-state disks, the LSI type first array card may be determined to be the first array card matched with two solid-state disks.

Or, in the related information of the first array card of the PMC type, the number of matched magnetic disks of the first array card of the PMC type is 2, and the types of the matched magnetic disks are all solid state disks, it may be determined that the first array card of the PMC type is the first array card matched with two solid state disks.

Under the condition that the first array cards matched with the two solid state disks exist in the plurality of first array cards, RAID1 can be established according to the first array cards matched with the two solid state disks and the two solid state disks matched with the first array cards matched with the two solid state disks.

For example, in one example, in the plurality of first array cards, the first array card collocated with the two solid state disks is one, so that RAID1 can be created according to the first array card collocated with the two solid state disks and the two solid state disks collocated with the first array card collocated with the two solid state disks.

Or in another example, in the plurality of first array cards, there are at least two first array cards collocated with two solid state disks, so that a first array card with the lowest sum of capacities of the collocated solid state disks can be selected from the at least two first array cards collocated with the two solid state disks, and then RAID1 is created according to the selected first array card and the two solid state disks collocated with the selected first array card. Therefore, the storage space occupied by creating RAID1 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

Or, under the condition that the first array cards matched with the two solid state disks do not exist in the plurality of first array cards, whether the first array cards matched with the two mechanical disks exist in the plurality of first array cards or not can be detected.

Wherein, in the case where the number of matched magnetic disks of the LSI type first array card in the related information of the LSI type first array card is 2 and the types of matched magnetic disks are all mechanical hard disks, it is possible to determine that the LSI type first array card is the first array card matched with two mechanical hard disks.

Or, in the case that the number of matched magnetic disks of the first array card of the PMC type in the related information of the first array card of the PMC type is 2 and the types of the matched magnetic disks are all mechanical hard disks, it may be determined that the first array card of the PMC type is the first array card matched with two mechanical hard disks.

In the case that the first array cards matched with the two mechanical hard disks exist in the plurality of first array cards, RAID1 may be created according to the first array cards matched with the two mechanical hard disks and the two mechanical hard disks matched with the first array cards matched with the two mechanical hard disks.

For example, in one example, in the plurality of first array cards, the first array card collocated with the two mechanical hard disks is one, so that RAID1 may be created according to the one first array card collocated with the two mechanical hard disks and the two mechanical hard disks collocated with the one first array card collocated with the two mechanical hard disks.

Alternatively, in another example, the first array cards collocated with the two mechanical hard disks are at least two in the plurality of first array cards, so that the first array card with the lowest sum of capacities of the collocated mechanical hard disks in the at least two first array cards collocated with the two mechanical hard disks can be selected, and then the RAID1 is created according to the selected first array card and the two mechanical hard disks collocated with the selected first array card. Therefore, the storage space occupied by creating RAID1 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

In the application, RAID1 is preferably established according to the first array card matched with the two solid state disks and the two solid state disks matched with the first array card matched with the two solid state disks, and RAID1 is established according to the first array card matched with the two mechanical disks and the two mechanical disks matched with the first array card matched with the two mechanical disks under the condition that the first array card matched with the two solid state disks does not exist in the plurality of first array cards, so that the performance of the established RAID1 is higher than that of the mechanical disks as much as possible, and the performance of the established RAID1 is higher as much as possible, and the performance of a KOS system preloaded on the established RAID1 is improved.

In the present application, the level of RAID includes: RAID0, RAID1, RAID0+1, RAID1+0, RAID3, RAID4, RAID5, and RAID6 are common, and RAID0, RAID1, RAID5, and the like, and the number of disks required for each level of RAID is different, for example, RAID0 may be created using 1 disk, RAID0 may be created using 2 disks, or RAID1 may be created using 3 or 4 disks, and RAID6 may be created using 3 or 4 disks.

In the case that the first array card matched with only two disks does not exist in the server, in step S103, it is detected whether the second array card matched with only one disk exists in the server.

Wherein, in the case where the number of matched magnetic disks of the LSI array card in the information about the LSI array card is 1, it is possible to determine that this LSI array card is a second array card that is matched and matches only one magnetic disk.

Alternatively, in the case that the number of disks collocated with the PMC array card in the related information of the PMC array card is 1, it may be determined that this PMC array card is a second array card collocated with only one disk.

In the case that there is a second array card collocated in the server and only one disk is collocated, in step S104, RAID0 is created according to the second array card and the one disk collocated by the second array card.

In one embodiment of the present application, the second array card collocated in the server and collocated with only one disk is one, so that RAID0 can be created according to the one second array card and the one disk collocated with the one second array card.

In another embodiment of the present application, the server has a plurality of second array cards collocated with one disk. Thus, one second array card may be selected among the plurality of second array cards, and then RAID0 may be created from the selected one second array card and the two disks collocated with the selected one second array card.

Therefore, whether the second array card matched with one solid state disk exists in the plurality of second array cards can be detected.

Wherein, in the case that the number of matched magnetic disks of the LSI type second array card in the related information of the LSI type second array card is 1 and the type of matched magnetic disk is a solid state disk, the LSI type second array card may be determined to be a second array card matched with a solid state disk.

Or, in the related information of the second array card of the PMC type, the number of matched disks of the second array card of the PMC type is 1, and the type of the matched disks is a solid state disk, it may be determined that the second array card of the PMC type is a second array card matched with a solid state disk.

Under the condition that a plurality of second array cards are matched with a second array card of a solid state disk, RAID0 can be established according to the second array card matched with the solid state disk and the solid state disk matched with the second array card of the solid state disk.

For example, in one example, in the plurality of second array cards, the second array card collocated with one solid state disk is one, so that RAID0 can be created according to the one second array card collocated with one solid state disk and the one solid state disk collocated with the one second array card collocated with one solid state disk.

Or in another example, in the plurality of second array cards, at least two second array cards matched with one solid state disk are arranged. Therefore, the second array card with the lowest capacity of the matched solid state disk can be selected from the at least two second array cards matched with one solid state disk, and RAID0 is built according to the selected second array card and the selected solid state disk matched with the second array card. Therefore, the storage space occupied by creating RAID0 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

Or, under the condition that the second array card matched with one solid state disk does not exist in the plurality of second array cards, whether the second array card matched with one mechanical hard disk exists in the plurality of second array cards or not can be detected.

Wherein, in the case where the number of matched magnetic disks of the LSI type second array card in the related information of the LSI type second array card is 1 and the type of matched magnetic disk is a mechanical hard disk, it is possible to determine that this LSI type second array card is a second array card matched with one mechanical hard disk.

And determining that the second array card of the PMC type is the second array card collocated with a mechanical hard disk under the condition that the number of matched magnetic disks of the second array card of the PMC type in the related information of the second array card of the PMC type is 1 and the type of the matched magnetic disks is the mechanical hard disk.

In the case that there is a second array card collocated with one mechanical hard disk in the plurality of second array cards, RAID0 may be created according to the second array card collocated with one mechanical hard disk and one mechanical hard disk collocated with the second array card collocated with one mechanical hard disk.

For example, in one example, in the plurality of second array cards, the second array card collocated with one mechanical hard disk is one, so RAID0 may be created according to the one second array card collocated with one mechanical hard disk and the one mechanical hard disk collocated with the one second array card collocated with one mechanical hard disk.

Or, in another example, the number of the second array cards collocated with one mechanical hard disk is at least two in the plurality of first array cards. Thus, the second array card with the lowest capacity of the matched mechanical hard disk can be selected from at least two second array cards matched with one mechanical hard disk. RAID0 is then created based on the selected second array card and the selected second array card collocated with a mechanical hard disk. Therefore, the storage space occupied by creating RAID0 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

In the application, RAID0 is preferably established according to the second array card matched with one solid state disk and one solid state disk matched with the second array card matched with one solid state disk, and RAID0 is established according to the second array card matched with one mechanical disk and one mechanical disk matched with the second array card matched with one mechanical disk under the condition that the second array card matched with one solid state disk does not exist in a plurality of second array cards, so that the performance of the established RAID0 is higher than that of the mechanical disk as much as possible, and the performance of the established RAID0 is higher as much as possible, and the performance of a KOS system preloaded on the established RAID0 is improved.

In the case that there is no second array card collocated with only one disk in the server, in step S105, it is detected whether there is a third array card collocated with more than three disks in the server.

Wherein, in the case where the number of matched magnetic disks of the LSI array card in the information about the LSI array card is 3 or more, it is possible to determine that this LSI array card is a third array card matched with three or more magnetic disks.

Or, in the case that the number of disks collocated with the PMC array card in the related information of the PMC array card is 3 or more, it may be determined that the PMC array card is a third array card collocated with three or more disks.

In the case where there is a third array card collocated with three or more disks in the server, in step S106, RAID1 is created according to the third array card and two disks of the same type among the three or more disks collocated with the third array card.

In one embodiment of the present application, the third array card with the same type as the at least two disks collocated with more than three disks in the server is one, and then RAID1 may be created according to the one third array card and two disks with the same type as the at least two disks collocated with the one third array card.

In one embodiment of the present application, the server has a plurality of third array cards with more than three disks and at least two disks with the same type, one third array card may be selected from the plurality of third array cards, and then RAID1 may be created according to the selected one third array card and the two disks with the same type in the three more than three disks with which the selected one third array card is collocated.

Therefore, whether the matched magnetic disk in the plurality of third array cards comprises the third array cards of the two solid state disks can be detected.

Wherein, in the case that the number of matched disks of the LSI type third array card in the related information of the LSI type third array card is 3 or more and the type of matched disk is a solid state disk, it may be determined that the LSI type third array card is a matched disk including a third array card of two solid state disks.

Or, in the case that the number of matched disks of the PMC type third array card in the related information of the PMC type third array card is 3 or more and the type of the matched disks is a solid state disk, it may be determined that the PMC type third array card is the third array card of the matched disk including two solid state disks.

Under the condition that the matched magnetic disk comprises the third array cards of the two solid state disks in the plurality of third array cards, RAID1 can be established according to the matched magnetic disk comprising the third array cards of the two solid state disks and the matched magnetic disk comprising the two solid state disks.

For example, in one example, in the plurality of third array cards, the collocated magnetic disk includes one third array card of two solid state disks. Thus, RAID1 may be created according to the one third array card with the matched disk including two solid state disks and the two solid state disks with the matched disk including the one third array card with the two solid state disks.

Or, in another example, in the plurality of third array cards, the collocated magnetic disk includes at least two third array cards of two solid state disks. Therefore, the third array card with the lowest sum of the capacities of the two matched solid state disks can be selected from the third array cards with at least two matched magnetic disks comprising the two solid state disks. And then creating RAID1 according to the selected third array card and the two solid state disks collocated with the selected third array card. Therefore, the storage space occupied by creating RAID1 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

Or, in the case that no matched disk includes two third array cards of the solid state disks in the plurality of third array cards, it may be detected whether there is a matched disk including two third array cards of the mechanical hard disks in the plurality of third array cards.

Wherein, in the case where the number of matched disks of the LSI type third array card in the related information of the LSI type third array card is 3 or more and the type of matched disk is a mechanical hard disk, it may be determined that this LSI type third array card is a matched disk including two mechanical hard disks.

Or, in the case that the number of matched disks of the PMC type third array card in the related information of the PMC type third array card is 3 or more and the type of the matched disk is a mechanical hard disk, it may be determined that the PMC type third array card is the third array card whose matched disk includes two mechanical hard disks.

In the case where there is a third array card in which the collocated disk includes two mechanical hard disks in the plurality of third array cards, RAID1 may be created according to the third array card in which the collocated disk includes two mechanical hard disks and the two mechanical hard disks collocated by the third array card in which the collocated disk includes two mechanical hard disks.

For example, in one example, in the plurality of third array cards, the collocated disk includes one third array card of two mechanical hard disks, and thus RAID1 may be created from the one third array card of the collocated disk including two mechanical hard disks and the two mechanical hard disks collocated with the one third array card of the collocated disk including two mechanical hard disks.

Alternatively, in another example, the collocated magnetic disk includes at least two third array cards of two mechanical hard disks in the plurality of third array cards. Thus, the third array card with the lowest sum of the capacities of the two matched mechanical hard disks can be selected from the third array cards with at least two matched magnetic disks comprising the two mechanical hard disks. RAID1 is then created based on the selected third array card and the two mechanical hard disks collocated with the selected third array card. Therefore, the storage space occupied by creating RAID1 can be reduced as much as possible, more storage space can be used for the server to do other things, and the utilization rate of the storage space is improved.

In the application, RAID1 is preferably established according to the matched disk comprising the third array cards of the two solid state disks and the matched disk comprising the two solid state disks, and RAID1 is established according to the matched disk comprising the third array cards of the two mechanical disks and the matched disk comprising the two mechanical disks under the condition that the matched disk comprising the third array cards of the two solid state disks does not exist in the plurality of third array cards. Therefore, the created RAID1 can be on the solid state disk as much as possible, and the performance of the solid state disk is always higher than that of the mechanical hard disk, so that the created RAID1 can be higher as much as possible, and the performance of the KOS system preloaded on the created RAID1 can be improved.

In summary, the order in which the array cards and disks collocated with the array cards are selected to create a RAID in the present application may be as shown in FIG. 2.

Secondly, before the RAID is created, the determined data comprise the type of the array card, the index serial number of the array card, the model number of the disk collocated with the array card and the like. The array card for creating RAID can be determined according to the type of the array card and the index serial number of the array card, and the disk for creating RAID can be determined according to the type of the disk collocated by the array card, so that RAID can be created according to the determined array card and the determined disk collocated by the array card.

After determining the array card and determining the disk collocated with the array card, how to create the RAID may refer to the current existing generation mode, which is not limited by the present application, and the present application focuses on determining the array card and the disk used for creating the RAID.
