Abstract

The invention relates to an access control method of network storage equipment, belonging to a computer network storage system. The invention solves the problem that the prior access control method maintains and manages one centralized access control list, thereby forming the performance bottleneck and influencing the performance and the expandability of the storage system. In the invention, the access control method comprises the steps of object establishment and object operation. The network storage equipment stores data objects and directory objects needed by users, each of the data objectsand the directory objects comprises an attribute part and a data part, and each attribute part comprises an access control list. The invention uses each access control list as a security attribute ofeach data object to be stored together with the data, defines the inherited rules of each access control list and the priority of each access control item, improves the flexibility of data access control, positions the corresponding access control list while reading the data to be operated by users, realizes the distributed access control, greatly reduces the access control cost of a distributedstorage system, and improves the expandability of the system.

Description

technical field

[0001] The invention belongs to a computer network storage system, and in particular relates to an access control method of a network storage device. Background technique

[0002] The expansion of the Internet has resulted in the explosive growth of data information in a geometric progression. Turing Award winner Jim Gray pointed out that the amount of new data added every 18 months in the network environment is equal to the sum of the amount of data in history. With the continuous development of applications such as digital libraries, e-commerce, medical imaging, bioengineering, scientific computing, virtual reality, digital earth, and website multimedia, there is a demand for the establishment of high-performance, high-reliability mass information storage systems. Future storage systems Its scale will reach PB level. The PB-level high-performance network storage system has hundreds of storage devices, and needs to provide concurrent and burst services to a...
