Detailed Description

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, data can be written into a hard disk through a read-write device, and stored data can also be read from the hard disk, so that the performance of the hard disk directly affects the overall performance of a system. For example, if the performance of the hard disk is poor, for example, the read-write speed is low, even if the read-write device has a high read-write speed, the overall read-write speed of the storage system composed of the hard disk and the read-write device is also low, that is, the performance is poor, and at this time, the performance of the read-write speed is not effectively utilized; if the performance of the hard disk is good, for example, the read-write speed is high, and the performance of the read-write device is poor, the overall performance of the russian storage system composed of the hard disk and the read-write device is also poor, at this time, the performance of the hard disk is not effectively utilized, and generally, the read-write device and the hard disk with good performance have high prices.

Therefore, when the performance of the read-write device and the connected hard disk is not matched, the performance of one device is not effectively utilized, the performance of a storage system consisting of the read-write device and the hard disk is not improved, and the overall cost is higher than expected.

In order to solve the above technical problem, an embodiment of the present application provides a method for adapting a hard disk, in which a read/write device is connected to the hard disk, a markup file of a preset position of the hard disk is obtained, the markup file is generated by a tooling system in advance according to a grade identifier of the hard disk, wherein the grade identifier of the hard disk is determined according to a performance of the hard disk, for example, a higher read/write speed corresponds to a higher performance grade, and whether the grade identifier of the hard disk matches the grade identifier of the read/write device is determined according to the performance of the read/write device, for example, the higher read/write speed corresponds to the higher performance grade, if the grade identifier of the hard disk does not match the grade identifier of the read/write device, it is determined that the performance grade identifiers of the hard disk and the read/write device do not match, a prompt can be performed at this time, thereby avoiding a problem that the read/write device does not adapt to the connected hard disk, therefore, the utilization rate of the hard disk is improved, and the working efficiency of the read-write equipment is improved.

Referring to fig. 1, the figure is a flowchart of a method for hard disk adaptation provided in an embodiment of the present application, and is applied to a read-write device, where the read-write device is connected to a hard disk, and the method includes the following steps.

S101, obtaining a mark file of a preset position of the hard disk.

In this embodiment of the present application, the read-write device may be a network storage device, or may be other devices that can write and read data to and from a hard disk. Different read-write devices can have different performances, specifically, the read-write devices can have data processing capacity, the data processing capacity of different read-write devices can be different, the read-write devices can have read-write capacity, and the read-write speed of different read-write devices can be different. The performance of the read-write device can be embodied by the level identifier of the read-write device, and the level identifier of the read-write device can be determined by the performance of the read-write device, for example, the level identifiers "a", "B", "C", "D", and "E" can respectively indicate the performance is good, medium, poor, and bad.

The hard disk is a device for storing data, and may be a SATA hard disk, a SAS hard disk, a solid state hard disk, and the like, and different hard disks may have different performances, specifically, different hard disks may have different memories, lifetimes, read/write speeds, and the like.

The tool system comprises a hard disk, a marking file, a tool system and a tool system, wherein the marking file can be stored in a preset position in the hard disk and is generated by the tool system according to a grade mark of the hard disk, and the grade mark of the hard disk is determined according to the performance of the hard disk.

The tooling system may be a device, such as a computer, having processing capabilities and read-write capabilities. Specifically, the tool system can detect the hard disk to obtain the performance of the hard disk, the performance of the hard disk can be embodied by the grade identification of the hard disk, and the grade identification of the hard disk is determined according to the performance of the hard disk. The rank indication of the hard disk may be, for example, "a", "B", "C", "D", and "E", respectively representing performance: excellent, good, medium, poor and inferior. It can be understood that the level identifier of the hard disk and the level identifier of the read-write device have a corresponding relationship.

After the grade identification of the hard disk is determined, the tool system can generate a marking file according to the grade identification of the hard disk.

Specifically, the tooling system may encrypt the peer identifier to obtain the markup file.

Specifically, the tooling system may also perform a verification operation on the level identifier of the hard disk through a preset verification Algorithm to obtain the markup file, where the preset verification Algorithm may be, for example, a HASH (HASH) Algorithm or a Message Digest Algorithm (Message-Digest Algorithm 5, MD 5).

Specifically, the tool system may also obtain the unique identifier of the hard disk, and encrypt the unique identifier and the level identifier of the hard disk according to an encryption key stored in advance by the tool system to obtain the markup file. The Encryption may be performed by a gpg Encryption tool, and the Encryption mode may be a symmetric Encryption, such as Data Encryption Standard (DES), Advanced Encryption Standard (AES), Triple Data Encryption Algorithm (3 DES), or an asymmetric Encryption, such as RSA (Ron Rivest-Adi Shamir-Leonard adapter), Digital Signal Algorithm (DSA), or gaelmal Algorithm. In addition, the unique identifier of the hard disk is an identifier that can identify different hard disks, and may be, for example, a serial number of the hard disk.

Specifically, the tool system can also perform verification operation on the unique identifier and the grade identifier of the hard disk through a preset verification algorithm to obtain a first operation value, and obtain the markup file according to the first operation value.

Specifically, the tooling system may also encrypt the first operation value obtained by the verification operation according to an encryption key stored in advance by the tooling system, so as to obtain the markup file.

After the mark file is generated, the tool system can write the generated mark file into a preset position of the hard disk. The preset location may be a location for storing user-defined data, which is not modified by default.

S102, judging whether the grade identification of the hard disk is matched with the grade identification of the read-write equipment or not, and prompting if not.

After the mark file of the preset position of the hard disk is obtained, the read-write device can judge whether the grade identifier of the hard disk in the mark file is matched with the grade identifier of the read-write device according to the mark file, if so, the read-write device considers that the performance of the hard disk is matched with that of the read-write device, the read-write device can perform read-write operation on the hard disk, and if not, the hard disk is considered to be not matched with the performance of the read-write device, for example, the high-performance read-write device is connected with the low-performance hard disk, or the low-performance read-write device is connected with the high-performance hard disk.

As a possible implementation manner, if the markup file is generated by encrypting the level identifier of the hard disk by the tooling system, it is determined whether the level identifier of the hard disk in the markup file matches the level identifier of the read-write device, which may specifically be to decrypt the markup file according to a decryption key stored in advance by the read-write device to obtain the level identifier of the hard disk, and then determine whether the level identifier of the hard disk matches the level identifier of the read-write device.

As another possible implementation manner, if the markup file is that the tooling system performs a verification operation on the level identifier of the hard disk according to a preset verification algorithm pre-stored by the tooling system to obtain a third operation value, and generates the markup file according to the third operation value, it is determined whether the level identifier of the hard disk in the markup file matches with the level identifier of the read-write device.

As another possible implementation manner, if the markup file is generated by encrypting the level identifier and the unique identifier of the hard disk by the tooling system, the determining whether the level identifier of the hard disk in the markup file matches the level identifier of the read-write device may specifically be that, according to a decryption key stored in advance by the read-write device, the markup file is decrypted to obtain the level identifier and the unique identifier of the hard disk, the unique identifier of the hard disk connected to the read-write device is obtained, whether the obtained unique identifier of the hard disk matches the decrypted unique identifier is determined, and if so, whether the decrypted level identifier of the hard disk matches the level identifier of the read-write device is determined.

As another possible implementation manner, if the markup file is that the tooling system performs verification operation on the unique identifier and the level identifier of the hard disk through a preset verification algorithm to obtain a first operation value, and the first operation value is used as the markup file, it is determined whether the level identifier of the hard disk in the markup file matches the level identifier of the read-write device, which may be specifically, obtaining the unique identifier of the hard disk connected to the read-write device, performing verification operation on the level identifier of the read-write device and the unique identifier of the hard disk through the preset verification algorithm to obtain a second operation value, and determining whether the first operation value matches the second operation value.

As another possible implementation manner, if the markup file is generated by the tooling system through performing verification operation on the unique identifier and the level identifier of the hard disk by using a preset verification algorithm to obtain a first operation value, and then encrypting the first operation value, it is determined whether the level identifier of the hard disk in the markup file matches the level identifier of the read-write device, and specifically, the method includes decrypting the markup file according to a decryption key stored in advance by the read-write device to obtain the first operation value, obtaining the unique identifier of the hard disk connected to the read-write device, performing verification operation on the obtained unique identifier of the hard disk and the read-write level identifier by using the preset verification algorithm to obtain a second operation value, and determining whether the first operation value matches the second operation value. Because the obtained unique identifier of the hard disk is fixed, if the first operation value is matched with the second operation value, the grade identifier of the hard disk is matched with the grade identifier of the read-write equipment.

It can be understood that the tooling system can also sign the markup file, and at this time, after the read-write device reads and writes the markup file, the read-write device can perform the steps of first de-signing the markup file and then performing the judgment step or the decryption step.

If the grade identification of the hard disk is not matched with the grade identification of the read-write equipment, the performance of the hard disk and the performance of the read-write equipment are not matched, at the moment, the overall performance of the storage system is low, the cost is high, and the effective utilization of the hard disk and the read-write equipment is not facilitated, so that prompt can be performed, and a user can connect other hard disks for the read-write equipment according to the prompt.

In the embodiment of the application, the grade identification of the hard disk can be determined according to the marking file.

As a possible implementation manner, the first level identifier may be subjected to a verification operation by using a preset verification algorithm to obtain a fifth operation value, where the first level identifier may be one of all the level identifiers of the hard disk, if the fifth operation value matches the first operation value in the markup file, the level identifier of the hard disk is considered as the first level identifier, if the fifth operation value does not match the first operation value in the markup file, the second level identifier may be subjected to a verification operation by using the preset verification algorithm to obtain a sixth operation value, the second level identifier may be a level identifier different from the first level identifier in all the level identifiers of the hard disk, if the sixth operation value matches the first operation value in the markup file, the level identifier of the hard disk is considered as the second level identifier, and if the sixth operation value does not match the first operation value in the markup file, the other level identifiers may also be subjected to a verification operation.

As another possible implementation manner, a preset verification algorithm may be performed on the first class identifier and the unique identifier of the hard disk through a preset verification algorithm to obtain a seventh operation value, and with reference to the above implementation manner, the class identifier of the hard disk is determined. For example, the read-write device may further determine a level identifier of the hard disk, specifically, hash operations may be performed on all level identifiers of the hard disk, such as "a", "B", "C", "D", and "E", and the unique identifier of the hard disk, and it is determined whether the obtained operation value matches the first operation value, where the level identifier corresponding to the operation value matching the first operation value is the level identifier of the hard disk.

In the method for adapting a hard disk provided by the embodiment of the application, a read-write device is connected with the hard disk to obtain a label file of a preset position of the hard disk, the label file is generated by a tool system in advance according to a grade identifier of the hard disk, wherein the grade identifier of the hard disk is determined according to the performance of the hard disk, for example, a higher read-write speed corresponds to a higher performance grade, whether the grade identifier of the hard disk is matched with the grade identifier of the read-write device is judged, wherein the grade identifier of the read-write device is determined according to the performance of the read-write device, for example, a higher read-write speed corresponds to a higher performance grade, if the grade identifier of the hard disk is not matched with the grade identifier of the read-write device, the performance grade of the hard disk is not matched with the performance grade identifier of the read-write device, a prompt can be given at the moment, thereby avoiding the problem that the read-write device is not matched with the connected hard disk, and improving the utilization rate of the hard disk, the work efficiency of the read-write equipment is improved.

Referring to fig. 2, a flowchart of another hard disk adapting method provided in an embodiment of the present application is applied to a tooling system, where the tooling system is connected to a hard disk, and the method includes the following steps.

S201, detecting the hard disk to obtain the grade identification of the hard disk.

The tooling system may be a device, such as a computer, having processing capabilities and read-write capabilities.

The hard disk is detected, so that the performance of the hard disk can be obtained, the grade identification of the hard disk is determined according to the performance of the hard disk, specifically, the automatic detection analysis and report information of the hard disk can be obtained through detection, and the information can comprise the unique identification and the grade identification of the hard disk. The unique identifier of the hard disk is an identifier capable of identifying different hard disks, for example, a serial number of the hard disk, and the rank identifier of the hard disk is an identifier capable of embodying the performance of the hard disk, for example, "a", "B", "C", "D", and "E", which respectively represent the performance: excellent, good, medium, poor and inferior.

S202, generating a marking file according to the grade identification of the hard disk.

After the grade mark of the hard disk is determined, a mark file can be generated according to the grade mark of the hard disk. Specifically, the level identifier may be encrypted to obtain a tag file, or the level identifier of the hard disk may be verified by a preset verification algorithm to obtain a third operation value, and the tag file is generated according to the third operation value, or the unique identifier of the hard disk may be obtained, and the unique identifier and the level representation of the hard disk may be encrypted according to an encryption key pre-stored in the tool system to obtain the tag file, or the unique identifier and the level identifier of the hard disk may be verified by the preset verification algorithm to obtain a first operation value, and the tag file may be generated according to the first operation value, or the first operation value obtained by the verification operation may be encrypted according to the encryption key pre-stored in the tool system to obtain the tag file.

It is understood that, in order to further improve the security of the markup file, in the embodiment of the present application, the generated markup file may also be signed.

And S203, writing the mark file into a preset position of the hard disk.

After the markup file is generated, the generated markup file may be written in a preset location of the hard disk. The preset location may be a location for storing user-defined data, which may not be modified by default.

When the hard disk is connected with the read-write equipment, the read-write equipment can acquire the label file in the hard disk, and judge whether the grade identifier of the hard disk is matched with the grade identifier of the read-write equipment or not according to the label file, if so, the performance of the hard disk is matched with that of the read-write equipment, the read-write equipment can carry out read-write operation on the hard disk, if not, the performance of the hard disk is not matched with that of the read-write equipment, for example, the high-performance read-write equipment is connected with the low-performance hard disk, or the low-performance read-write equipment is connected with the high-performance hard disk, at the moment, the overall performance of the storage system is low, the cost is high, the effective utilization of the hard disk and the read-write equipment is not facilitated, and at the moment, a prompt can be carried out, so that a user can connect other hard disks for the read-write equipment according to the prompt.

In the embodiment of the application, in order to prevent illegal personnel from maliciously marking the hard disk, the tool system can be verified, and only if the tool system passes the verification, the marking file can be written in the preset position of the hard disk.

Specifically, the tooling system may send attribute information of the tooling system to the authorization device, so that the authorization device authenticates the tooling system according to the attribute information. The attribute information of the tool system may include at least one of information of a Central Processing Unit (CPU), memory information, a serial number of a boot disk, a Media Access Control (MAC) address, an Identification (ID) of an operating system, and the like in the tool system. The authorization device may be a device with data processing capabilities, such as a computer device.

In order to enhance the security of the attribute information of the tool system, the attribute information of the tool system may be encrypted according to an encryption key pre-stored in the tool system to obtain encrypted attribute information, and the encrypted attribute information of the tool system may be sent to the authorization device.

The authorization device receives the attribute information of the tool system, authenticates the tool system according to the attribute information of the tool system, specifically, the authorization device can judge whether the attribute information of the tool system is matched with the attribute information stored in advance, if yes, the authentication is passed, an authentication file is generated, and if not, the authentication is not passed.

After receiving the encrypted attribute information of the tool system, the authorization device can decrypt the attribute information of the tool system according to a decryption key prestored by the authorization device, wherein the decryption key corresponds to the encryption key prestored by the tool system, if the attribute information of a plaintext can be obtained, the decryption is successful, the authentication can be considered to pass, an authentication file is generated, and if the decryption is not successful, the authentication is not considered to pass. Of course, the authorization device may also determine whether the attribute information of the tooling system matches the attribute information stored in advance.

The authorization device generates an authentication file, which may specifically be that the authorization device uses the acquired attribute information of the tool system as the authentication file, or signs the acquired attribute information of the tool system to obtain the authentication file, or decrypts the encrypted attribute information of the tool system according to a decryption key stored in advance by the authorization device to obtain the attribute information of the tool system, and signs the attribute information to obtain the authentication file.

After the authorization equipment generates the authentication file, the authentication file can be sent to the tooling system, and the authentication file can also be stored to a position designated by the tooling system, so that the authorization of the tooling system is completed.

The tooling system may acquire the authentication file from the authorization device, for example, receive the authentication file from the authorization device, or read the authentication file from the authorization device at a specified location.

After the authentication file is obtained, the authentication file may be verified. Specifically, whether the attribute information in the acquired authentication file is matched with the attribute information of the tool system or not can be judged, and before judgment, the authentication file can be subjected to label release.
