Embodiment Construction

[0014] image 3 A structural schematic diagram of the present invention is given. and figure 2 In contrast, the configuration and implementation of a virtual disk array is distributed across multiple servers. Wherein, the configuration of the virtual disk array is not completed on the server 1 , but is completed through a virtual storage server 5 . The virtual storage server 5 virtualizes one or more disk array devices 3 connected through the high-speed Internet 2 into a virtual disk array pool 4 through its virtual storage configuration and management 6 . Different applications require virtual disk arrays with different availability configurations. This requires that the virtual disk array pool includes various virtual disk arrays, configured and managed by the virtual storage server 5 according to different requirements of the server 1, and the corresponding server 1 is responsible for implementing the virtual disk array. In this way, the performance and scalability of ...

Abstract

The high-availability network memory system based on configurable virtual disc array includes virtual memory server to virtualize disc array device connected to the network into virtual disc array pond; virtual configuration and management unit connected to the virtual memory server to configure and manage the virtual disc array pond; and server to realize the virtual disc array. The virtual disc array is distributed in several servers and supports several serving nodes to raise the performance expandability of the system greatly. In addition, different virtual disc arrays may be configured based on different availability requirement of different services. The present invention can support several servers and realize expansion of availability and flexible configuration and management.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a highly available network storage system. Background technique [0002] In a network storage system, a disk array (RAID for short) is a physical storage medium commonly used at present. Due to its low price, good performance and fault tolerance, disk array has become the first choice of various network storage systems. figure 1 A schematic diagram of the network storage system using disk array is given. One or more servers 1 are connected to one or more disk array devices 3 through a high-speed Internet 2, and each disk array device includes an array controller 4 and one or more disk arrays 5 under its planning. [0003] With the rapid development of network technology and various network applications, such as data centers and e-commerce, figure 1 The structure shown has become more and more difficult to meet the requirements of various applications on the network storag...
