Problems solved by technology

[0004] FC is a serial interconnection technology that combines traditional channel technology and network technology, enabling it to achieve reliable data transmission over long distances, but its expensive equipment and management costs have become the biggest problem restricting FC SAN
The InfiniBand specification (IBA) uses channel-based point-to-point connections, which can be applied to server internal communication, interconnection, server and storage devices, and interconnection between storage devices, but the initial investment and cost are too high, and there is still a long way to go before large-scale applications

Embodiment Construction

[0015] A storage system access control method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] The invention provides a storage system access control method, the access control method is usually used in SAN storage systems, because storage devices are connected to many front-end systems in SAN storage systems, therefore, it is necessary to protect valuable data on each system , to prevent other front-end systems from accessing data without authorization, or destroying data. The method can effectively solve the problem of unauthorized front-end system accessing data in the SAN storage system. as attached figure 1 As shown, the specific implementation process is: set up a three-layer architecture, namely the upper layer, the middle layer and the lower layer. The lower layer completes the same virtualization of the physical storage device through the virtualization module to obtain the virtual storage space, and t...

Abstract

The invention provides a storage system access control method. The realization process of the method is listed as follows: a three-layer framework, which is composed of an upper layer, an intermediate layer and a lower layer, is arranged. Identical virtualization of a physical storage device is completed by the lower layer via a virtualization module so that a virtual storage space is obtained. Then the virtual storage space is mapped to the intermediate layer. An LUN is mapped to different areas via an LUN isolation module by the intermediate layer. Compared with methods in the prior art, valuable data in each system are protected and access to the data or damage to the data without authorization by other front-end systems is prevented by the storage system access control method so that the storage system access control method is great in security, high in practicality and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of communication information, in particular to a storage system access control method for effectively solving the problem of unauthorized front-end system accessing data in a SAN storage system. Background technique [0002] A storage area network (SAN) is a high-speed network or subnetwork that provides data transfer between computers and storage systems. A storage device is one or more disk devices used to store computer data. A SAN network consists of a communication structure responsible for network connections, a management layer responsible for organizing connections, storage components, and computer systems to ensure the security and strength of data transmission. [0003] Currently, there are three main protocols for building SAN solutions: FC (Fibre Channel Protocol), Infiniband, and iSCSI. [0004] FC is a serial interconnection technology that combines traditional channel technology and network ...
