Application Of Distributed Storage Technology In Office Automation System

With the rapid development of cloud computing technology, Distributed storage technology is becoming more and more important. Especially, it is widely used in the storage of unstructured data(such as video, pictures, files, etc.). The distributed storage technology has the characteristics of fast reading and writing speed, and also is a good solution to the problem of data backup.In order to improve the carrying capacity of China Telecom’s office automation platform, and customer service perception, based on the current user data storage capacity, application architecture and the actual situation of storage resources, In this paper, we introduce the requirement of the distributed storage technology.Through the distributed storage technology, we establish a unified data storage and backup resource pool. The composition of the resource pool is mainly composed of 3 parts, include management node, metadata log node and storage node. Through the establishment of centralized and independent distributed storage resource pool, core database pressure is reduced. The distributed storage resource pool has the ability of data multi copy,auto resource management and high concurrent read data, supporting for storage resource across physical devices, cross regional calls, so the intensive layout is conducive to the rapid deployment of products, improve the utilization of storage resources, and a single storage node’s hardware dysfunction does not affect the business use.
