Access control method and apparatus

Abstract

The invention provides an access control method and apparatus. The method comprises the following steps of obtaining a virtual software framework interface and a multi-path plug-in corresponding to a storage device; and through the multi-path plug-in and the virtual software framework interface, connecting the storage device into a virtual platform. According to the technical scheme, through the design of the virtual software framework interface and the multi-path plug-in corresponding to the storage device, storage devices of different manufacturers can be dynamically connected into the virtual platform, so that the situation that software of the virtual platform needs to be re-designed when a new storage device is connected into the virtual platform is avoided, and the cost is greatly reduced; and meanwhile, the characteristics of multi-path driving software in the storage devices of the manufacturers are fully utilized, so that the compatibility and competitiveness of virtual products are improved.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to an access control method and device. Background technique [0002] In the virtualization platform, storage virtualization technology can shield the underlying storage system and hardware complexity, integrate various storage functions and services, and provide a unified and multi-functional storage service externally, which is an indispensable key technology for virtualization; storage One of the important functions of virtualization is to shield the differences of the underlying storage hardware, and provide a unified storage service to the outside world on the basis of making full use of its storage hardware characteristics, so that it can break the boundaries of different storage vendors and avoid being tied to specific Manufacturers can make full use of existing equipment and reduce costs. [0003] The multipath function is one of the key storage features...

AI Technical Summary

Problems solved by technology

[0003] The multipath function is one of the key storage features supported by most manufacturers. In a SAN (Storage Attached Network, storage area network) environment, when a manufacturer's storage device is connected to a virtualization platform, since the manufacturer provides its own multipath Therefore, it is necessary to customize the development of storage virtualization software for this manufacturer. When other manufacturers’ storage devices are connected to the virtualization platform, it is necessary to re-customize the development of storage virtualization software, which greatly increases the development cost.

[0004] Linux provides the device mapping layer multipath software based on Device Mapper, that is, DM-Multipath software, so that the storage devices of various manufacturers can support the multipath function without installing their multipath driver software. However, the device mapping layer multipath The software supports a software-based Device Mapper mechanism, and its performance is not as good as that of each manufacturer's own multi-path driver, and it is difficult to make full use of the characteristics of each manufacturer's multi-path driver
