Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of cloud storage, and in particular to a storage resource configuration method and device. BACKGROUND

[0002] Blockchain is a new application mode of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm. In recent years, blockchain technology has been increasingly applied in various industries. For example, cloud storage is built on the basis of blockchain. Specifically, by issuing equivalent virtual currencies, a large number of personal computer (PC) users are attracted to contribute idle storage resources and network bandwidth, and a network distributed storage resource pool is built.

[0003] Since the nodes in the distributed storage network based on blockchain are all non-dedicated servers and non-dedicated storage devices, the reliability of a single node is very poor. In order to improve the reliability of the distributed storage network, the prior art adopts the following ways: 1. Through a downtime penalty measure (for example, when the storage resources and network bandwidth contributed by a PC user are unavailable, the virtual currency income thereof is deducted), the node offline caused by active shutdown and service stop is reduced; 2. Through a multi-copy storage mode, the availability of data is ensured.

[0004] Currently, an operating company can obtain a large amount of storage resources provided by PC users by issuing virtual currencies, and the cost of storage resources is very low, and the users using the blockchain storage resources are still relatively few. Therefore, the multi-copy storage mode can meet the data reliability requirements in a period of time. However, storage resources are limited, and as the number of users using storage resources increases, the cost of storage resources will also increase accordingly, so the multi-copy storage mode will not be able to meet the data reliability needs of future development. Therefore, when the cost of storage resources rises and the demand for storage resources increases, how to improve the utilization rate of storage resources while ensuring data reliability is a problem to be solved. SUMMARY

[0033] For the sake of clear and concise description of the following embodiments, a brief introduction of the related art is given first:

[0034] A storage system based on blockchain technology is a decentralized distributed storage system that does not require a third-party central authority. The data after decomposition can be encrypted using a personal key and then dispersed throughout the network. The data can be extracted at any time when the user uses it, and the data reorganization process can also be seamlessly implemented. When the data is attacked by hackers, the hacker also needs to crack the secret key of each file. When the hacker tries to tamper with the data, the user can also retrieve the file and destroy the data at any time. Therefore, the application of blockchain technology is very helpful to the development of the cloud storage industry.

The network 101 can refer to the Internet, an operator network, a private network, etc. The network 101 includes network devices such as routers and switches. The workstation 102 can be a personal computer (PC), or a dedicated workstation or server. The network 101 can be a bridge between the workstations 102, and the workstations 102 exchange information through the network 101.

[0036] Blockchain cloud storage is based on a blockchain network, and each node provides storage and computing resources to the network to build a storage resource network. Figure 2 A simplified example diagram of a blockchain cloud storage network provided for the prior art is shown in FIG. 2. The network includes storage nodes 201, computing nodes 202, and computing and storage nodes 203.

[0037] In order to solve the problem of how to improve the utilization of storage resources while ensuring data reliability when the cost of storage resources rises and the demand for storage resources increases, the embodiment of the present application provides a storage resource configuration method, and the basic principle is: after obtaining the hardware storage resources, the hardware storage resources are divided according to the preset rules to obtain virtual storage resources of n storage capacities, and the initial available level of the virtual storage resource of the i-th storage capacity is determined, wherein the number of the virtual storage resource of the i-th storage capacity in the virtual storage resources of n storage capacities is x i , i is an integer, i takes 1 to n, n is an integer greater than or equal to 1, and the number of the virtual storage resources of n storage capacities can be the same or different; then, the virtual storage resource meeting the disk establishment request information is determined from the virtual storage resources of n storage capacities according to the disk establishment request information, the available level of the j-th virtual storage resource and the DN-RAID technology, the disk establishment request information includes available level request information and storage capacity request information, and the available level of the j-th virtual storage resource is the available level corresponding to the virtual storage resource of the storage capacity indicated by the storage capacity request information. The storage resource configuration method provided by the embodiment of the present application divides the hardware storage resources according to the preset rules to obtain virtual storage resources of multiple storage capacities, and initializes the available level of the virtual storage resource, so as to select the virtual storage resource meeting the available level request information and the storage capacity request information from the virtual storage resources of multiple storage capacities when constructing the DN-RAID. Thus, the utilization of the storage resources is improved while ensuring the data reliability.

[0038] The implementation of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Figure 3A logical example diagram of a blockchain cloud storage network is provided for the embodiments of the present application. The blockchain cloud storage network includes a physical topology layer 301, a resource topology layer 302, a resource management layer 303, and a user layer 304. The physical topology layer 301 includes physical devices that provide hardware storage resources and hardware computing resources, and the physical devices can be a PC. The resource topology layer 302 includes hardware storage resources and hardware computing resources. In the resource topology layer 302, the hardware resources can be divided according to their functions, i.e., resources providing computing functions are divided into hardware computing resources, and resources providing storage functions are divided into hardware storage resources. The resource management layer 303 is used for logical management of the hardware storage resources and the hardware computing resources. The application scenario of the present application is in the field of blockchain cloud storage, i.e., in a blockchain cloud storage network, according to the preset rules provided by the embodiments of the present application, the hardware storage resources are divided to obtain virtual storage resources of n storage capacities, and the initial available levels of each virtual storage resource are determined, so that users can select virtual storage resources that meet the available level request information and the storage capacity request information from the virtual storage resources of multiple storage capacities, and build a distributed storage network based on blockchain. Thus, the utilization rate of storage resources is improved while ensuring data reliability. The user layer 304 includes the physical form of virtual storage resources, which can be a database or a PC.

[0040] Figure 4 A flowchart of a storage resource configuration method is provided for the embodiments of the present application, as shown in Figure 4 The method can include:

[0041] S401, according to the preset rules, the hardware storage resources are divided to obtain virtual storage resources of n storage capacities.

[0042] It can be understood that each virtual storage resource can be regarded as a unit disk. The unit disk is a hardware storage resource provided by a storage node, which is divided into one or more storage units according to the preset rules, and each storage unit is a unit disk. The storage capacities of the plurality of storage units can be completely the same. Of course, the storage capacities of the plurality of storage units can also be completely different, i.e., the storage capacities of each storage unit are different. The storage capacities of the plurality of storage units can also not be completely the same, i.e., the storage capacities of at least two storage units in the plurality of storage units are the same.

[0043] According to preset rules, hardware storage resources can be divided into n virtual storage resources with different storage capacities, where n is an integer greater than or equal to 1. For example, when n = 1, it means that the hardware storage resources are divided according to the preset rules, resulting in one type of virtual storage resource with different storage capacities. When n is greater than or equal to 2, it means that the hardware storage resources are divided according to the preset rules, resulting in two or more types of virtual storage resources with different storage capacities. The number of virtual storage resources with different storage capacities of n can be the same or different. The number of virtual storage resources of the i-th type among the n types of virtual storage resources is x. i Let i be an integer, ranging from 1 to n. That is, the number of the first type of virtual storage resource is x1, the number of the second type of virtual storage resource is x2, and so on, up to the number of the nth type of virtual storage resource being x. n .

[0044] For example, hardware storage resources can be partitioned based on the maximum capacity of a storage unit, the minimum capacity of a storage unit, and the ratio of storage unit capacities to obtain virtual storage resources with n different storage capacities. The relationship between the maximum capacity of a storage unit, the minimum capacity of a storage unit, and the ratio of storage unit capacities is: Y = Z. m *X, where Y represents the maximum capacity of a storage unit, X represents the minimum capacity of a storage unit, Z represents the ratio of storage unit capacities, and m is an integer greater than or equal to 0. The total storage capacity of the partitioned hardware storage resources can be expressed by the formula: Where, x i x represents the number of virtual storage resources of the i-th storage capacity. i x needs to be satisfied i <Z. u i u represents the storage capacity of the i-th type of virtual storage resource. i =Z i *X. Q represents the total storage capacity of the partitioned hardware storage resources, i.e., the hardware storage resources include x. i Block size is u i For virtual storage resources Q, Q needs to satisfy Q≤P<Q+u i P represents the storage capacity of the hardware storage resources.

[0045] Assuming the minimum storage unit capacity is 4GB, the storage unit capacity ratio is 4, and the maximum storage unit capacity is 1024GB, according to Y=Z m *X can divide hardware storage resources into virtual storage resources of 5 different storage capacities. When m=0, Y=Z m *X=1*4=4, meaning the storage capacity of the first type of virtual storage resource is 4GB; when m=1, Y=Z m *X = 4 * 4 = 16, meaning the storage capacity of the second type of virtual storage resource is 16GB; when m = 2, Y = Z m*X = 16 * 4 = 64, i.e. the storage capacity of the third kind of virtual storage resource is 64 GB; when m = 3, Y = Z m *X = 64 * 4 = 256, i.e. the storage capacity of the fourth kind of virtual storage resource is 256 GB; when m = 4, Y = Z m *X = 256 * 4 = 1024, i.e. the storage capacity of the first kind of virtual storage resource is 1024 GB.

[0046] It is assumed that the division result of the hardware storage resource can be represented as [x1, x2, x3, x4, x5]. For example, for a hardware storage resource with a storage capacity of 100 GB, it can be divided into 1 4 GB virtual storage resource, 2 16 GB virtual storage resources, and 1 64 GB virtual storage resource, and the division result can be represented as [1, 2, 1, 0, 0]. For a hardware storage resource with a storage capacity of 200 GB, it can be divided into 2 4 GB virtual storage resources and 3 64 GB virtual storage resources, and the division result can be represented as [2, 0, 3, 0, 0]. For a hardware storage resource with a storage capacity of 300 GB, it can be divided into 3 4 GB virtual storage resources, 2 16 GB virtual storage resources, and 1 256 GB virtual storage resource, and the division result can be represented as [3, 2, 0, 1, 0]. For a hardware storage resource with a storage capacity of 400 GB, it can be divided into 1 16 GB virtual storage resource, 2 64 GB virtual storage resources, and 1 256 GB virtual storage resource, and the division result can be represented as [0, 1, 2, 1, 0]. For a hardware storage resource with a storage capacity of 600 GB, it can be divided into 1 16 GB virtual storage resource, 1 64 GB virtual storage resource, and 2 256 GB virtual storage resources, and the division result can be represented as [0, 1, 1, 2, 0]. For a hardware storage resource with a storage capacity of 700 GB, it can be divided into 3 4 GB virtual storage resources, 3 16 GB virtual storage resources, 2 64 GB virtual storage resources, and 2 256 GB virtual storage resources, and the division result can be represented as [3, 3, 2, 2, 0]. For a hardware storage resource with a storage capacity of 1 TB (1024 GB), it can be divided into 1 1024 GB virtual storage resource, and the division result can be represented as [0, 0, 0, 0, 1]. For a hardware storage resource with a storage capacity of 2 TB (2048 GB), it can be divided into 2 1024 GB virtual storage resources, and the division result can be represented as [0, 0, 0, 0, 2]. The storage resource pool of the blockchain-based distributed storage network obtained after the division of the hardware storage resources with the above respective storage capacities includes 9 4 GB virtual storage resources, 9 16 GB virtual storage resources, 9 64 GB virtual storage resources, 6 256 GB virtual storage resources, and 3 1 TB virtual storage resources.

[0047] S402, determining an initial available level of the i-th virtual storage resource of the storage capacity.

[0048] The available level can refer to a level of the availability of the virtual storage resource. The availability can refer to a ratio of a normal use duration of the virtual storage resource within a preset duration to the preset duration. The preset duration can be one month or half a year, etc.

[0049] The preset available level can include -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and 6. The availability of -4 is lower than 30%. The availability of -3 satisfies [30%, 50%). The availability of -2 satisfies [50%, 70%). The availability of -1 satisfies [70%, 80%). The availability of 0 satisfies [80%, 90%). The availability of 1 satisfies [90%, 99%). The availability of 2 satisfies [99%, 99.9%). The availability of 3 satisfies [99.9%, 99.99%). The availability of 4 satisfies [99.99%, 99.999%). The availability of 5 satisfies [99.999%, 99.9999%). The availability of 6 is greater than or equal to 99.9999%.

[0050] After the virtual storage resources of n storage capacities are divided according to the preset rule, the available levels of the virtual storage resources of n storage capacities are initialized. For any virtual storage resource of n storage capacities, the initialization can be performed according to the following manner. When initializing the i-th virtual storage resource, a relatively low initial available level can be set for the i-th virtual storage resource, for example, the initial available level of the i-th virtual storage resource can be -3. Alternatively, when setting the initial available level for the i-th virtual storage resource, the available level information of the virtual storage resource provided by a user can also be referred to.

[0051] S403, determining a DN-RAID that meets the disk establishment request information from the virtual storage resources of n storage capacities according to the disk establishment request information, the j-th virtual storage resource available level, and the DN-RAID technology.

[0052] The disk establishment request information includes available level request information and storage capacity request information. The j-th virtual storage resource available level is the available level corresponding to the virtual storage resource of the storage capacity indicated by the storage capacity request information. For example, the j-th virtual storage resource available level is the initial available level corresponding to the virtual storage resource of the storage capacity indicated by the storage capacity request information.

[0053] The number of virtual storage resources corresponding to the storage capacity request information can be determined according to the available level of the virtual storage resource corresponding to the storage capacity indicated by the available level request information and the storage capacity request information, and then the DN-RAID is created according to the number of virtual storage resources. It should be noted that when the unit disk is selected according to the storage capacity indicated by the storage capacity request information, the unit disk can be intelligently selected according to the unit disk topology information. For example, the unit disks distributed on different storage nodes in the blockchain cloud storage network are selected according to the unit disk topology information, and the DN-RAID is created, so as to further improve the reliability of the DN-RAID, and avoid affecting the reliability of the DN-RAID by selecting the unit disks on the same storage node. In addition, the DN-RAID level can be intelligently selected according to the available level request information, and the DN-RAID is constructed. For example, the unit disks are grouped into a disk array through the DN-RAID technology, the performance can be improved through data striping, and the reliability can be improved through data mirroring. The disk formed by grouping the unit disks through the DN-RAID has high availability and high performance, for example, a high-availability network disk (HAND). The DN-RAID level includes six levels, such as DN-RAID0 level, DN-RAID1 level, DN-RAID2 level, DN-RAID3 level, DN-RAID4 level and DN-RAID5 level.

[0054] An example is taken to illustrate the process of establishing the DN-RAID, taking a 4-level available disk with a capacity of 256GB as an example (the performance improvement through striping is not considered here). The DN-RAID1 is created, and all the 256GB unit disks are selected. The initial availability level of the 256GB unit disk is-2 level, and the minimum availability corresponding to the-2 level is 50%. Therefore, the availability of the DN-RAID1 formed by K disks is A = 1-(1-50%) K The array with a 4-level availability needs to be created, and the minimum availability corresponding to the 4 level is 99.99%. Therefore, A ≥ 99.99%, and the value of A is substituted into A = 1-(1-50%) K The calculation result is K ≥ 7, so at least 7 pieces of 256GB unit disks should be selected to form the DN-RAID1. That is, the DN-RAID1 formed by at least 7 pieces of 256GB unit disks can provide an available disk with a 4-level availability and a capacity of 256GB.

[0055] Further, after determining the initial availability level of the virtual storage resource of the i-th storage capacity, the availability level of the virtual storage resource of the i-th storage capacity can be updated according to the available duration of the virtual storage resource of the i-th storage capacity. As shown in Figure 5 The embodiment of the present application can further include the following steps.

[0056] S501, determining the available duration ratio of the virtual storage resource of the i-th storage capacity according to the available duration of the virtual storage resource of the i-th storage capacity and the preset duration.

[0057] The preset duration can be one month, that is, the virtual storage resource of the i-th storage capacity can be evaluated every month to update the available level of the virtual storage resource of the i-th storage capacity.
