Example Embodiment

[0049] Example 1:

[0050] figure 2The flow chart of the disk access control method provided by the embodiment of the present invention specifically includes the following processing flow:

[0051] Step 201, receiving a disk access request from an application server.

[0052] In the embodiment of the present invention, a disk array is created and initialized on the storage device, and the disk array is divided into multiple user data volumes. On the application server, after the operating system mounts the storage device through the network, a disk is generated for each user data volume, and the disk can provide the application server with a read-write interface for accessing the disk. The application server can request access to the disk by requesting to load the file system metadata of the disk. When the disk is a network disk, perform the following steps 202-207.

[0053] Wherein, the inherent information of the application server is obtained by the file system on the ...

Example Embodiment

[0076] Example 2:

[0077] Based on the same inventive concept, according to the disk access control method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 2 of the present invention also provides a disk access control device, the structural diagram of which is as follows Figure 4 shown, including:

[0078] a receiving unit 401, configured to receive an application server's access request to the disk;

[0079] The first calculation unit 402 is configured to perform hash calculation on the acquired inherent information of the application server when the disk is a network disk;

[0080] A matching unit 403, configured to match the attribution field set in the header of the file system corresponding to the disk with the hash calculation result;

[0081] A first allowing access unit 404, configured to allow the application server to access the disk if the matching is successful;

[0082] The denying unit 405 is configured to de...

Abstract

The invention discloses a disk access control method and device. The disk control method and device comprises the steps that an access request of an application server for a disk is received; when the disk is a network disk, hash calculation is carried out on the acquired inherent information of the application server; an affiliation field set in the head part of a file system corresponding to the disk is matched with a hash calculation result; if matching is successful, the application server is allowed to have access to the disk; if matching fails, the application server is refused to have access to the disk. By means of the scheme, the access of the application server to the disk is automatically and effectively controlled.

Description

technical field [0001] The invention relates to the field of computers, in particular to a disk access control method and device. Background technique [0002] With the advent of the era of big data, data storage technology has also developed rapidly. In the early days, there was direct attached storage (DAS, Direct Attached Storage) technology of large servers. In order to improve the utilization of storage space, storage area network (SAN , Storage Area Network), Network Attached Storage (NAS, Network Attached Storage) and other technologies, among them, the IP SAN technology based on the network protocol (IP, Internet Protocol), can be shared and used due to the transmission of data through the IP network and the construction of a storage network Large-capacity storage space is not limited by transmission speed, distance, and capacity, and can be expanded freely, so it is widely used. [0003] If the storage device has 16 physical disks, five of them can be combined into...
