Embodiment Construction

[0033] The overall design principle of the present invention is: centralized decision-making, distributed processing. The design strategy of the present invention mainly includes: on the system structure, select a dedicated server mode to process metadata; on data access, select a direct access mode; on the mapping from files to system servers, select a dynamic single mapping mode; on data consistency , select the file contract method.

[0034] Compared with the serverless method (Serverless method), the system structure and function division of the dedicated server (group) method is clearer; when the storage system is upgraded, there is no need to upgrade the application server; the data is confidential; the storage system is easy to control and manage And optimization without being affected by the application server; in addition, it also has good scalability.

[0035] Direct data access means that the storage device is directly connected to the network, and the server direc...

Abstract

A server system and method based on network storage and scalable architecture, interconnected switching network, all servers and network storage devices in the system are distributed and connected through the interconnected switching network; multiple application servers running application programs are connected through the interconnection Connect the switching network to access the metadata information of the metadata server and the load balancing server, and directly access the data on the storage device through the interconnection switching network; multiple metadata processing metadata information servers provide metadata access and operation services; at least A load balancing server, which completes the dynamic mapping of files to metadata servers and dynamic balance of system load; network storage device, stores metadata and data. The present invention has good expansibility, including the expansibility of performance and the expansibility of storage capacity. Under the condition that the system structure remains basically unchanged, the performance and capacity of the system can both increase with the increase of the network bandwidth.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a computer server system and method based on network storage and scalable architecture. Background technique [0002] The server system based on network storage and scalable architecture refers to the design of the server system, with the storage system as the core, emphasizing the reliability, high performance, scalability, manageability and dynamic processing capabilities of data services. The technology commonly used today is SAN (Storage Area Network). [0003] A SAN is a high-speed dedicated storage network or subnet similar to a normal LAN. The SAN structure contains an independent network or subnet, and Fiber Channel is the backbone of this network. SAN structure such as figure 1 As shown, the server 1 and the storage device 3 are separated, and the server accesses the storage device through the fiber channel network 2 . Storage devices include disk arrays and the...
