[0025] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0026] In addition, the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0027] Please refer to Figure 1 As shown, the centralized storage management method provided by the present invention specifically includes:

[0028] S101 obtains managed host node information and storage device information in a target management system;

[0029] S102 collects the physical nodes corresponding to the host node information and the disks corresponding to the storage device information according to the preset period according to the host node information and the storage device information, and obtains hardware information and configuration information;

[0030] S103 associates the hardware information and the configuration information with the host information to generate a query information set;

[0031] S104 obtains change requirement parameters, and obtains corresponding hardware information and configuration information through the query information set according to the host information in the change requirement parameters;

[0032] S105: performing change processing on the corresponding hardware information and configuration information according to the change requirement parameters, and feeding back the change result to the provider of the change requirement parameters.

[0033] In actual work, the above method mainly provides services for IT administrators, connecting to the company's storage devices, heterogeneous physical servers (including physical server nodes such as Windows, Linux, Unix), and the company's heterogeneous virtualization platforms (such as Openstack and VMware).

[0034] Please refer to Figure 2 As shown, in one embodiment of the present invention, collecting the physical nodes corresponding to the host node information according to the preset period respectively includes:

[0035] S201 obtains identification information of the physical node and unique identification information of the FC port of the host bus adapter;

[0036] S202 generates a keyword in the information key value according to the identification information, and generates a key value of the key-value pair according to the unique identification information;

[0037] S203 generates hardware information using the keyword and the key value.

[0038] In actual work, in order to solve the problem that the host information in the SAN storage device cannot be associated with the actual physical nodes of the enterprise, the above embodiment can use a crawler-like method to collect information on the managed host nodes. It is assumed that the server collection component can grasp the application purposes of all managed nodes, such as the IP address of the node (such as 56.78.90.11), the purpose of use (such as a certain application, a certain virtualization platform, a certain host machine), the user department and other information. If it cannot be grasped, the relevant information can be obtained from the business configuration management database (CMDB). Specifically, the key hardware information of the physical node can be collected regularly (such as every 1 hour, or when the node is enabled, or after the node has undergone hardware changes). (For example, connect to Linux through the SSH protocol, and Esxi collects information through the cli command line). When collecting data, select the unique identifier of the physical device in the enterprise (such as the device serial number, IP address, etc.) as the keyword (Key) in the key-value (KV Pair) pair of the information sent; collect the name of the FC port (also called the initiator) of the HBA (Host Bus Adapter) card of the node and the port WWN (also called the initiator WWN) as the value (Value) of the key-value pair. After collecting the key-value pair of each host, it is stored in the information centralized storage device with the usage information from the CMDB and the HBA port as the record dimension, as shown in Table 1 below.

[0041] In one embodiment of the present invention, collecting the disk corresponding to the storage device information according to the storage device information at a preset period includes: collecting the configuration information of the disk corresponding to the storage device information through a command line or an HTTP-based programming interface at a preset period. In actual work, in order to solve the problem that the host information in the SAN storage device cannot be associated with the actual physical node of the enterprise, a crawler-like method can be used to collect information from the managed centralized storage device. Usually, a storage device will be configured to maintain a mapping on it to provide storage services for the host, such as Figure 3 The storage mapping diagram shows that a mapping includes a port group, a host group, and a LUN group. Under each port group, there are one or more ports; under each host group, there are one or more hosts; under each LUN group, there are one or more LUNs. Under each host, there are one or more initiators. Specifically, the configuration information of all managed disk drives can be collected and recorded in the information storage component through the command line (CLI) or HTTP-based programming interface (RESTAPI) on a regular basis (such as every hour, every 12 hours, etc.). In general, all relevant information of the disk drive is collected, among which the mapping relationship example is shown in Table 2 below, and the relationship between the host and the initiator is shown in Table 3 below.

[0046] In one embodiment of the present invention, associating the hardware information and the configuration information through the host information to generate a query information set further includes: providing the query information set to a predetermined location for display and output. In actual work, in order to solve the problem that the host information in the SAN storage device cannot be associated with the actual physical node of the enterprise, a relational database can be used to associate and aggregate the above-obtained information. By associating Table 1 and Table 3 through the condition that the host initiator WWN is equal, the following result Table 4 is obtained:

[0047] Table 4

[0048]

[0049] Afterwards, the contents in Table 4 are stored and displayed for query by IT administrators or other relevant personnel. Through such information collection, aggregation, and online display, information matching is transformed from the original manual query to a quasi-real-time query, which facilitates IT administrators to quickly collect statistical data, analyze usage, diagnose faults, and evaluate availability. Furthermore, various associated queries can be constructed according to enterprise needs to display different query results. For example, (disk drive-mapping-host-usage-host ID), (host-disk drive-LUN group), (disk drive-port group-sum of LUN groups), etc.

[0050] In order to solve the problem that the changes of a large number of storage devices require manual operations by IT administrators, the WEB front desk can allow IT administrators to make changes to servers and storage devices online through the WEB. Generally, changes to enterprise SAN storage devices include new storage allocation, existing storage expansion, storage resource recovery, etc. Taking new storage allocation as an example, in the past, when IT administrators made such changes, they needed to do the following: Figure 4The multi-role manual operation of the traditional storage new allocation change shown requires the collection of host IP, host ID, and each port WWN for recording, and these parameters are manually filled in the mapping allocation when the storage is allocated; the LUN needs to be manually created and added to the LUN group according to the required LUN specifications. In one embodiment of the present invention, the change requirement parameters include LUN specifications, port groups, physical node identifiers, and host information. Furthermore, the change processing of the corresponding hardware information and configuration information through the change requirement parameters includes: after changing the hardware information and the configuration information according to the change requirement parameters, constructing a mapping relationship between the disk and the host, and adjusting the corresponding unique identification information of each host in the hardware information for storage allocation. In actual work, using the above embodiment, only one IT administrator is required to log in to the WEB front desk of the present invention and enter simple requirement parameters (without entering complex WWNs) to accurately complete storage allocation. Specifically, the WEB front desk receives the change elements such as LUN specifications, port groups, and physical host node IDs input by the administrator. According to the physical host ID, by querying the data in the information centralized storage component, the WWN information of each physical node involved in the change and other elements of this change (LUN specifications, port groups, etc.) are sent to the SAN change implementation component. Afterwards, the LUN, LUN group, host, host group, and mapping creation are automatically completed, and each host is automatically managed. The WWN is completed, the automatic allocation of storage is completed, and then the newly allocated storage is identified and formatted, and the change results are fed back to the IT administrator through the WEB front desk.

[0051] Please refer to Figure 5 As shown, the present invention also provides a centralized storage management device, which includes: a server information collection module, a centralized storage information collection module, an information centralized storage module and a change processing module; the server information collection module is used to obtain the managed host node information in the target management system; the physical nodes corresponding to the host node information are collected according to the host node information at a preset period to obtain hardware information; the centralized storage information collection module is used to obtain the managed storage device information in the target management system; the disks corresponding to the storage device information are collected according to the storage device information at a preset period to obtain configuration information; the information centralized storage module is used to associate the hardware information and the configuration information through the host information to generate a query information set, store and display the query information set; the change processing module is used to obtain change requirement parameters, obtain the corresponding hardware information and configuration information through the query information set according to the host information in the change requirement parameters; and, change the corresponding hardware information and configuration information through the change requirement parameters, and feedback the change results to the provider of the change requirement parameters.

[0052] In the above embodiment, the server information collection module includes: obtaining the identification information of the physical node and the unique identification information of the FC port of the host bus adapter; generating a keyword in the information key value according to the identification information, and generating a key value of the key-value pair according to the unique identification information; generating hardware information through the keyword and the key value. Specifically, the server information collection module can be similar to the crawler technology to collect information on the managed host node. In another embodiment, when configuring the initiator of the host on the storage device, only the WWN information can be entered. Therefore, when the IT administrator is performing storage device maintenance, he cannot understand which physical node in the environment this WWN and the host on it specifically correspond to. The above-mentioned server collection component collects the WWN information of the server node and associates and matches the WWN on the disk drive with the WWN of the server.

[0053] In one embodiment of the present invention, the information centralized storage module can query the query information set through a similar method as described above; through such information collection, aggregation, and online display, the information matching is transformed from the original manual query to a quasi-real-time query, which facilitates IT administrators to quickly collect statistical data, analyze usage, diagnose faults, evaluate availability, etc. In order to solve the problem that the change of a large number of storage devices requires manual operation by IT administrators, the WEB front-end, i.e., the change processing module, can allow IT administrators to perform change operations on servers and storage devices online through the WEB. Generally, changes to enterprise SAN storage devices include new storage allocation, existing storage expansion, storage resource recovery, etc. Taking new storage allocation as an example, in the past, when IT administrators made such changes, they needed to perform traditional multi-role manual operations; they needed to collect host IP, host ID, and each port WWN for recording, and manually fill these parameters into the mapping allocation when allocating storage; they needed to manually create LUNs according to the required LUN specifications and add them to the LUN group.

[0054] The beneficial technical effects of the present invention are: it solves the problem that IT administrators cannot quickly and accurately match the hosts on the storage devices with the actual physical and running business associations in the IT environment when making storage allocation, expansion and recovery changes, thereby improving the accuracy and efficiency of IT administrators in service identification and service provision; it provides IT administrators with one-stop WEB-based storage changes, eliminating the need for IT administrators to query and obtain complex change parameters, allowing IT administrators to quickly and accurately complete storage changes with minimal effort, thereby improving the efficiency of enterprise IT supply.
