Description

Locating system for storage resources

technical field

The invention relates to a resource positioning system, in particular to a resource storage positioning system.

Background technique

With the explosive growth of information volume, the demand for storage devices of various application systems has increased significantly. Therefore, a single storage device can no longer meet the growing demand for storage space. Therefore, some manufacturers set up multiple storage device nodes on the network through network connection. And on each storage device node, various storage devices are connected to increase the storage space of the storage device.

In order to facilitate the management of these storage devices, they will be stored in specific spaces, such as computer rooms or servers. When there are more storage devices, the connecting wires will also increase accordingly. In this way, the administrator cannot find specific data storage devices from these devices or wires.

Contents of the invention

In view of the above problems, the object of the present invention is to provide a storage resource positioning system, which is used to point out the storage location of a specific storage resource in a storage system.

The storage resource positioning system disclosed in the present invention includes a storage device, a resource mapping module, a resource positioning module and a main control module. The storage device has at least one storage resource. The resource location module connects the resource mapping module and the main control module. The resource mapping module records resource codes of stored resources. The main control module is connected to the resource mapping module, and the main control module receives resource calling requirements and outputs corresponding resource merging results. The resource location module searches for the resource code in the resource mapping module according to the resource calling requirement, and searches for other storage resources and resource codes connected to the resource code. The resource locating module merges the repeatedly found storage resources, and outputs the storage resources as a result of resource merging.

The storage resource locating system of the present invention can point out the storage location of a specific storage resource in the storage system, so as to provide the user with a fast way to find the physical device of the storage resource.

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

Please refer to FIG. 1A , which is a schematic diagram of the architecture of the present invention. The storage resource location system of the present invention includes a storage device 110, a resource mapping module 120 (Resource Map), a resource location module 130 (Resource Locator), a main control module 140, a resource merger module 150 (resource merger) and an interface display module 160. There may be at least one storage resource in the storage device 110 , or the same storage resource is shared by multiple storage devices 110 . The storage resources described in the present invention can be but not limited to physical storage devices 110 such as storage devices 110 of independent disks, disk arrays (Redundant Array of Independent Disks, RAID), and can also be applied in network small computer system interfaces (Internet Small Computer System Interface, iSCSI), storage area network (storage area network, SAN), logical volume (logical volume), snapshot (snapshot), file (document), disk cluster (Just a Bunch Of Disks, JOBDS), directory or In the network storage device 110.

In addition to being connected to the resource location module 130 , the main control module 140 is also connected to the interface display module 160 at the same time. The resource location module 130 is connected to the main control module 140 , the resource mapping module 120 and the resource merging module 150 . The main control module 140 is used for receiving resource calling requirements, and outputting corresponding resource merging results. After the main control module 140 receives the resource calling request, the main control module 140 calls the resource mapping module 120 to find the location of the resource in the storage device 110 . The resource mapping module 120 is used to point to the physical location of the file data in the storage device 110 . Therefore, the resource mapping module 120 can locate the required resources. And each resource mapping module 120 is responsible for one mapping. Since the storage device 110 may have multiple levels at the same time, such as file system, snapshot, logical volume, RAID, etc., each level needs a resource mapping module 120 . The following is an example of a logical volume (Logical Volume) and please cooperate with Figure 1B. For users, a logical volume is a block device (BlockDevice) similar to a hard disk. However, in terms of hardware and software implementation, a logical volume may be composed of multiple storage areas on different storage devices (such as hard disks, RAID). As shown in the figure below, on the two storage devices, there are three logical volumes——LV-1, LV-2, and LV-3. Storage device one has logical volume LV-1 and a part of logical volume LV-2, while storage device two has another part of logical volume LV-2 and logical volume LV-3. In order to specifically point out that each segment of each logical volume (LV-1, LV-2, LV-3) exists in that area on the underlying storage device, the present invention therefore maps the actual stored position by the mapping module .

A storage resource may contain several fragments, so the present invention adopts the form of a range group composed of multiple ranges. The resource calling requirement in the present invention is composed of information range set (Range Set), storage resource mark (Resource ID), storage location start position (Start Address), storage resource length (Length) and storage resource attribute (Attributes) ) constitutes. The information range set of the present invention is represented by the following formula:

Range Set＝{Range1, Range2,..., Range n}

The information range set contains at least one resource (Range n, n is a positive integer). Among them, each resource can be further defined as:

Range=(Resource ID, Start Address, Length, Attributes)

Wherein, Resource ID is storage resource sign, represents the specified file or storage device 110, can be file name, directory name, device name etc. Start Address is the starting location of the resource. Length is the length of the resource. Attributes are special attributes of the data included in this range, such as the original data, mirror data (Mirror) or snapshot (Snapshot) of the file. The StartAddress or Length in the Range Set can be replaced by ALL to indicate the entire range of the specified storage resource.

The resource location module 130 is responsible for controlling the location processing, and the resource location module 130 invokes the resource mapping module 120 according to the received information range set. Please refer to FIG. 2, the operation flow of the resource location module 130 of the present invention is as follows:

Step S210: the resource location module receives the input information range set #i;

Step S220: find the corresponding resource mapping module #i;

Step S230: call the resource mapping module machine to the resource mapping module #(i+n) in sequence, and use the output of each resource mapping module as the input of the next resource mapping module, wherein i and n are integers;

Step S240: According to the invocation result of the resource mapping module, determine whether to call the resource merging module, remove duplicated ranges and merge adjacent ranges; and

Step S250: Output the final information range set #(i+n) as a resource combination result.

First, the resource location module 130 receives an input information range set #i from the main control module 140 . The resource location module 130 searches from the i-th storage resource to the n-th storage resource sequentially according to the set of input information ranges. In the present invention, the output of each resource mapping module 120 is used as the input of the next resource mapping module 120 . In other words, the resource output of the i-th storage resource becomes the input of the i+1-th storage resource. If the resource locating module 130 finds that the output of each storage resource is duplicated, the resource locating module 130 will remove the duplicate range, and the resource merging module 150 will merge adjacent ranges. The resource locating module 130 outputs the final information range set #(i+n) as a resource merging result. After the main control module 140 receives the output of the resource locating module 130 , the main control module 140 will drive the interface display module 160 to display the resource merging result. The interface display module 160 can be a display (displayer) or a display light signal (Light-Emitting Diode, LED).

In order to clearly illustrate the operation of the present invention, the following description is used as an example, but not limited to this hardware and its structure. Suppose storage device D contains the following layers:

(1) File system
