Embodiment 1

[0025] This embodiment is a network storage system based on grid technology, including a network terminal as a user, the network terminal is connected to a management node as a server through the Internet, a wide area network, or a local area network, and the management node communicates with various heterogeneous storage systems through the Internet, wide area network, or local area network. The organization's PCs, workstations, and workstation clusters provide users with storage node connections for storage services in the form of grid services.

[0026] In this embodiment, the resources of various heterogeneous computers (including PCs, workstations and even clusters, etc.) running different operating systems (which can be Windows, Unix, etc.) are connected through the grid middleware to construct a storage system whose capacity can be dynamically expanded . Each storage node is connected to the management node through the enterprise's internal LAN, and users can connect to...

Embodiment 2

[0029] This embodiment is a refinement of the first embodiment, and is about the specific composition of the management node in the first embodiment. Such as figure 1 As shown: the management node includes a NAT (adding a Chinese name in front) module that translates the private network IP address inside the cluster into a legal network IP address when a workstation cluster is added to the storage system. The NAT module is connected with the system database module that records and generates node resource information necessary for system operation, node storage cost information, user information, file storage information, and system operation logs. The system database module is connected with the Web service module that provides storage services to users in the form of Web Service. The system database module is connected with the node resource monitoring module which uses the resource monitoring service provided by each storage node to realize dynamic discovery and monitoring ...

Embodiment 3

[0038] This embodiment is a refinement of Embodiment 1, and it is about the composition of the storage nodes described in the embodiment, such as figure 1 shown. The storage node includes a resource monitoring service module connected with the node resource monitoring module of the management node and responsible for monitoring its own resource utilization information. The storage service module connected with the storage service monitoring module of the management node is responsible for starting the storage service of the storage node and registering the storage service module with the storage service monitoring module of the management node in the form of a "soft state" life cycle. The resource monitoring service module and the storage service module are connected to each other.

[0039] The storage node is another important part to realize the network storage of the present invention, and the included modules are:

[0040] Resource monitoring service module: This module ...

Abstract

The invention relates to a network storage system based on a grid technology, which is used for virtualizing a large amount of existent even idle heterogeneous computer resources with dispersed geographic positions on network in an enterprise into a single storage system. The network storage system comprises a network terminal as a user connected with a management node as a server via internet orWAN or LAN. The management node is connected with storage nodes of heterogeneous PC, workstation and workstation cluster for providing storage service for the user in a grid service form. The networkstorage system effectively reduces the cost for constructing a large number of data storage systems in the enterprise, ensures safety authentication of user identity, encrypted transmission of data and safety of data access and transmission via network, provides a uniform and transparent storage access mechanism, and solves the problem of interoperability between different storage nodes.

Description

technical field [0001] The invention relates to a network storage system based on grid technology, which is an electric digital processing system and a storage system of a computer network system. Background technique [0002] Existing network storage systems can be mainly divided into two categories: one is a storage system based on Network Attached Storage (NAS) technology; the other is a storage system based on Storage Area Network (Storage Area Network, SAN) technology. However, both storage systems have certain drawbacks. To build a NAS storage system, you need to purchase special NAS equipment, and the disk array must be equipped with a dedicated file server, which is expensive in the later expansion; and the general file server does not have a high-availability configuration, which is prone to single-point failures; in addition, the network protocol adopted by NAS The access method poses a threat to the data security of the storage system. SAN is a network architect...
