[0082] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0083] The storage resource expansion technology of the open platform (system) in the embodiments of this specification can be applied to the financial field or other fields, and can be selected according to needs, and this specification does not limit this. In view of the problem of high manpower consumption and low efficiency caused by manual storage resource expansion of the open platform. The embodiments of this specification provide an automatically executable open platform storage expansion method, which can be used on any suitable computer device, which can be part of the open platform or independent of the open platform.

[0084] refer to Figure 1 As shown, in some embodiments of this specification, the open platform storage capacity expansion method may include the following steps:

[0085] S101: Receive a storage expansion request for a target server.

[0086] S102: Collect basic data of the target server based on a preset script program.

[0087] S103: Confirm whether the storage capacity expansion request is allowed according to the basic data.

[0088] S104: When the storage expansion request is allowed, lock the allocatable storage array from the allocatable storage pool set.

[0089] S105: Expand storage resources of the target server using the allocatable storage array.

[0090] In an embodiment of the present specification, when a storage expansion request for a target server is received, basic data of the target server can be collected based on a preset script program, and whether the storage expansion request is allowed can be confirmed based on the basic data; when the storage expansion request is allowed, the allocatable storage array is locked from the allocatable storage pool set, and then the storage resources of the target server are expanded using the allocatable storage array, thereby realizing automatic expansion of the open platform storage resources, thereby improving the efficiency of the open platform storage resource expansion and reducing the manpower consumption of the open platform storage resource expansion.

[0091] In some embodiments of this specification, a storage expansion request can be initiated based on an event trigger. For example, when the target server receives a storage capacity alarm, it can issue a storage expansion request (or a storage expansion instruction). Of course, this is just an example. In other embodiments of this specification, a storage expansion request can also be automatically initiated through other methods such as scheduled tasks, and this specification does not limit this. The target server here is a server in the open platform that needs storage expansion (such as an application server, etc.).

[0092] In the embodiment of this specification, the storage expansion request may include: the IP address of the target server, the expansion operation type (such as new construction, expansion, etc.), the expansion path and the target capacity, etc. The expansion path may refer to the path of the file system corresponding to the target server.

[0093] The script is pre-added to the target server, and its main purpose is to automatically collect the basic data of the target server when it is started. Therefore, this script can be added to any server in the open platform that may have expansion requirements, so as to facilitate the automatic expansion of storage resources.

[0094] The basic data may include information such as the storage disk type, multipath software type, and file system type of the target server. Among them, the storage disk type refers to the storage disk type of the storage disk that has been allocated to the target server for use. For example, in one embodiment of the present specification, the storage disk type may be divided according to the storage disk interface type (such as IDE storage disk, SATA storage disk, SCSI storage disk, etc.). In other embodiments of the present specification, the storage disk type may also be divided using any other suitable dimension, and the present specification does not limit this. Multipath software is a software device on the server that can aggregate the same storage resources flashed by different host bus adapters into a block for use in scenarios such as link redundancy control and load balancing control. Different types of storage disks have different types of multipath software installed or configured, that is, different types of storage disks have specific multipath software types.

[0095] In some embodiments of the present specification, the confirming whether to allow the storage capacity expansion request according to the basic data includes:

[0096] 1) Analyze the basic data.

[0097] 2) Confirm whether the storage disk type is in a storage disk type whitelist, or confirm whether the multipath software type is in a multipath software type whitelist.

[0098] In a target server based on an operating system such as Linux, in order to maintain the performance of the server, a storage disk type whitelist or a multipath software type whitelist may be pre-configured to determine whether to allow the storage resources of the target server to be expanded.

[0099] 3) When the storage disk type is in the storage disk type whitelist, or the multipath software type is in the multipath software type whitelist, it can be predicted whether the file system type exceeds its storage capacity upper limit after expansion.

[0100] Among them, the basic data includes the current capacity of the file system of the corresponding file system. The current capacity of the file system plus the specified expansion capacity is the storage capacity of the file system type after expansion. By comparing the expanded storage capacity with the upper limit of the storage capacity of the file system type, it can be predicted whether the file system type exceeds its storage capacity upper limit after expansion. For example, in an exemplary embodiment, the file system type of the target server is EXT3 (that is, the third-generation Linux extended file system), and the maximum capacity of EXT3 is 16T. If the current capacity of the file system corresponding to the target server is 5T and the target capacity is 10T, the specified expansion capacity is 10T-5T=5T. Since 10T<16T, it can be predicted that this storage expansion request does not exceed the storage capacity upper limit.

[0101] 4) If it is not exceeded, the storage expansion request is allowed, and the basic data is updated to the database. Updating the basic data to the database can facilitate the use in subsequent steps.

[0102] In some other embodiments of the present specification, when the storage capacity expansion request meets one of the following rejection conditions, the storage capacity expansion request may be rejected, wherein the rejection condition includes:

[0103] 1. The storage disk type is not in the storage disk type whitelist;

[0104] 2. The multipath software type is not in the multipath software type whitelist;

[0105] 3. The file system type exceeds its storage capacity limit after expansion.

[0106] It should be noted that the processing logic for determining whether to allow the storage expansion request can be changed according to actual needs. For example, in other embodiments of this specification, other judgment conditions (such as Figure 2 The “other judgment conditions” in the description are not limited to this.

[0107] In some embodiments of the present specification, locking the allocatable storage array from the allocatable storage pool set may include the following steps:

[0108] 1) Obtain the allocated storage disk information of the target server from the database.

[0109] The basic data includes the allocated storage disk information of the target server. In one embodiment of the specification, the allocated storage disk information may include: the current allocation rate, current usage rate and current total number of logical unit numbers (LUNs) of the file system corresponding to the target server.

[0110] 2) Generate a set of allocatable storage pools.

[0111] The allocatable storage pool set refers to the allocatable storage pool list generated by the built-in function. The allocatable storage pool list records the information of all the allocatable storage pools. The allocatable storage pools corresponding to this information can all be candidates for capacity expansion, that is, some storage arrays can be allocated from these allocatable storage pools for the target server capacity expansion.

[0112] 3) According to the allocated storage disk information, select an allocatable storage array with a designated expansion capacity from the allocatable storage pool set.

[0113] In an embodiment of the present specification, selecting an allocatable storage array of designated expansion capacity from the allocatable storage pool set according to the allocated storage disk information may further include:

[0114] a) Selecting (e.g., sequentially selecting) an allocatable storage pool from the allocatable storage pool set.

[0115] b) predicting, based on the current allocation rate, current usage rate and current total number of LUNs, whether the allocation rate, usage rate and total number of LUNs of the file system exceed corresponding upper limits (upper limit thresholds) after the allocatable capacity of the allocatable storage pool is allocated. The allocatable capacity of the allocatable storage pool refers to the maximum allocatable capacity of the allocatable storage pool.

[0116] c) If the allocation rate, usage rate and total number of LUNs of the file system exceed the corresponding upper limits after the allocable capacity of the allocable storage pool is allocated, then it is confirmed whether the allocable capacity reaches the specified expansion capacity. Otherwise, the next allocable storage pool can be taken to continue the judgment.

[0117] d) If the allocatable capacity does not reach the specified expansion capacity, continue to allocate from the remaining allocatable storage pools in the allocatable storage pool set until the allocated allocatable capacity reaches the specified expansion capacity.

[0118] For example, in an embodiment of the present specification, the allocatable storage pool set has 10 allocatable storage pools, and the specified expansion capacity is 5T. When the allocatable capacity of the first allocatable storage pool is 1T, since 1T is less than 5T, the second allocatable storage pool needs to be used for continued allocation; if the allocatable capacity of the second allocatable storage pool is also 1T, the accumulated allocatable capacity reaches 1T+1T=2T at this time, and since 2T is still less than 5T, the third allocatable storage pool needs to be used for continued allocation; this is repeated recursively until the accumulated allocatable capacity reaches the specified expansion capacity.

[0119] Of course, when the total allocatable capacity of all the allocatable storage pools in the allocatable storage pool set does not reach the specified expansion capacity, a prompt is output and a user interface (such as Figure 3 As shown in the figure, it is convenient for users to operate, so that when the automatic pre-disk partitioning fails, manual intervention can be performed so that the subsequent automatic expansion steps can continue to be executed. The pre-disk partitioning here means to pre-lock some allocatable storage arrays before the formal disk partitioning.

[0120] 4) Locking the allocatable storage array and updating the database with the pre-allocated disk information.

[0121] Before the formal partitioning, locking the allocatable storage array can prevent conflicts in storage resource allocation and use, thereby helping to improve the stability of the open platform.

[0122] In some embodiments of the present specification, the use of the allocatable storage array to expand the storage resources of the target server may include the following:

[0123] 1) Put the allocable storage array into the lun group (lun_group) corresponding to the target server. Each target server corresponds to a lun_group, and a lun_group can have one or more luns.

[0124] For example, in Figure 4In the illustrated embodiment, placing the allocable storage array into the lun_group corresponding to the target server may include: obtaining information of the locked allocable storage array from a database; logging into the locked allocable storage array according to the information; confirming whether the lun_group corresponding to the target server exists in the allocable storage array; when the lun_group corresponding to the target server exists in the allocable storage array, confirming whether the luns of all storage disks in the allocable storage array exist in the lun_group; if there is a lun with a storage disk in the allocable storage array that does not exist in the lun_group, adding it to the lun_group. Of course, if the lun_group corresponding to the target server exists in the allocable storage array, a prompt of failure of automatic disk partitioning (here, disk partitioning refers to the formal disk partitioning mentioned above) may be output to inform the user.

[0125] 2) Calling a configuration refresh instruction to refresh the allocatable storage array from the target service.

[0126] 3) Adding the refreshed allocable storage array to the file system corresponding to the target server.

[0127] like Figure 5 As shown, in some embodiments of the present specification, adding the refreshed allocatable storage array to the file system corresponding to the target server may include: determining whether the refreshed allocatable storage array has been used; if not, calling the Automatic Storage Management (ASM) or the Logical Volume Manager (LVM) to add the refreshed allocatable storage array to the file system corresponding to the target server.

[0128] Among them, ASM is a very outstanding new feature in Oracle Database 10g, which provides services such as file system, logical volume manager and software disk array in a platform-independent way. ASM can stripe and mirror disks, so that disks can be added or removed while the database is loaded. It also supports direct and asynchronous I / O and uses the Oracle Data Manager API (simplified I / O system call interface) introduced in Oracle9i.

[0129] Logical Volume Manager is a disk management technology implemented in Linux 2.4 kernel and above. It is a mechanism for managing disk partitions in Linux environment. LVM, a disk management mechanism, can be used not only on Linux systems, but also on UNIX, Windows and other operating systems. The working principle of LVM is actually very simple. It abstractly encapsulates the underlying physical hard disk and then presents it to the upper-level application in the form of a logical volume. In the traditional disk management mechanism, the upper-level application directly accesses the file system to read the underlying physical hard disk. In LVM, it encapsulates the underlying hard disk. When operating the underlying physical hard disk, it no longer operates on the partition, but performs the underlying disk management operation on it through a logical volume. For example, if a physical hard disk is added, the upper-level service is unaware of it at this time, because the logical volume is presented to the previous service.

[0130] Although the process flows described above include multiple operations that occur in a particular order, it should be clearly understood that the processes may include more or fewer operations, which may be performed sequentially or in parallel (eg, using parallel processors or a multi-threaded environment).

[0131] Corresponding to the above-mentioned open platform storage expansion method, the embodiment of this specification also provides an open platform storage expansion device. Figure 6 As shown, in some embodiments of this specification, the open platform storage expansion device may include:

[0132] The receiving module 61 may be used to receive a storage expansion request for a target server;

[0133] The collection module 62 may be used to collect basic data of the target server based on a preset script program;

[0134] A confirmation module 63 may be used to confirm whether the storage expansion request is allowed according to the basic data;

[0135] The locking module 64 may be used to lock the allocatable storage array from the allocatable storage pool set when the storage expansion request is allowed;

[0136] The expansion module 65 may be used to expand the storage resources of the target server using the allocatable storage array.

[0137] For the convenience of description, the above device is described in various units according to their functions. Of course, when implementing this specification, the functions of each unit can be implemented in the same or multiple software and / or hardware.

[0138] The embodiments of this specification also provide a computer device.
