| With the rapid development of computer technology and communicationtechnology, the organization of storage, and the construction materials has not only away to purchase a server which, today’s network has entered the era of efficient useof resources. Formed by the data network development has brought a lot of pressurefor today’s storage technology. To make the storage technology and the ability tohandle huge amounts of data has been improved, using a distributed file system hasevolved into a historically inevitable trend and the technology has been graduallyforming. OA (Office Automation System) system has been gradually developed froma single system through the system to become a coordination office distributedsystems, cloud computing to solve collaborative OA system deployment and improvethe effective use of server hardware has become a very popular topic. Meanwhile OAsystem files to be stored and processed has also been growing, so, how to combinecloud computing to solve technical difficulties also store various files that must beaddressed immediately.Because cloud computing is only in recent years the theory put forward, there arefew companies in the country will be applied to the concept of cloud computing OAsystem, the more is in the research stage, rarely applied in practice development. Bystudying the characteristics of the application of OA system, this paper established aEucalyptus cloud infrastructure, has become the infrastructure OACloudimplemented to improve the system resource utilization. On this basis, OA systemcreated for a relatively stable working platform, and OA system must buildapplications. The OA system built on OACloud, while the development of user-friendly management OACloud management tools, allowing users to facilitatethe operation and management of cloud OA system needs.Remove OACloud function of a variety of storage problems also exist in thesystem itself has done a thorough research. Through the study of the system, wherethe use of the storage system as HDFS. According to the status of OA systemavailable in the market now, the two proposed structural model file storage. The fileson the system for a reasonable merger deal, not only to meet the needs HADOOPhandle large data, but also speed up the processing efficiency of small files. Byreasonable set of files stored on the machine to be controlled storage file. This papertests the various treatments for OA system files in the test, including file merging,upload, and read. After laboratory tests, design ideal and the reality of the system toreach agreement, and meet the requirements of the system files are stored, OA officesystems suitable as a basic storage system.In the end of this article, the author carefully summarized in the research processinvolved in technology and the author of the major work done, and on a few issuesstill exist in the system put forward some ideas for improvement.In today’s rapid development of Internet technology, a variety of technologiesemerging, in which among the many technologies, cloud computing is one of themost striking one is the most innovative technology. The so-called cloud computing,you can use a very easy to understand example to understand, in a village, eachhousehold in order to facilitate water in every household hit a well, although doing sois very convenient, but drilling costs and future maintenance cost is a large sum,since not everyone can be for farmers in terms of commitment, so in order to makebetter use of water resources, the organization played a deep well in the village, thewhole village to meet the water volume wells. Just after the villagers erected pipelineto bring water to the house, and then pay according to the amount of water, so thereare maintenance costs can also reduce development costs. From this example, we seethat, in fact, easy to understand cloud computing is the cloud and the client, thecloud is that deep wells, the client is the villagers. The client sends a resource allocation and service costs associated with the payment, according to therequirements of cloud resources proposed by the client, the user requests to the client.Here, the cloud mainly play the role of a rational allocation of resources. Cloudcomputing is not just a technology, but also a service. |
