Server system expansion method and apparatus and expansion processing device

Abstract

The embodiment of the invention provides a server system expansion method and apparatus and an expansion processing device. The method comprises the following steps: for a non access layer server, determining a server expansion number of each service cluster; after the server expansion number of each service cluster of the non access layer server is determined, and the non access layer server is expanded, simulating a business request in an access layer service cluster; in a process of simulating the service request, if the query rate per second QPS corresponding to the access layer service cluster cannot be improved by increasing the flow of the business request, after the number of the access servers of the access layer service cluster is increased according to a preset number, judging whether the QPS is increased; and if so, determining the number of the access servers of the access layer service cluster, which needs to be increased according to the set number again, until the QPS reaches a set QPS value. The expansion manner provided by the invention is relatively rational, the condition of resource waste of the server of the expanded server system can be reduced.

Description

technical field [0001] The invention relates to the technical field of server capacity expansion, in particular to a server system capacity expansion method, device and capacity expansion processing equipment. Background technique [0002] The server system is a server cluster composed of many servers, which can provide business services for users through the server system; at present, the server system is generally set up as a multi-layer server structure, such as access layer servers, business logic layer servers, and job layer servers ( Such as leaf node server), etc.; among them, the access layer server can receive the business request, and send the business request to the corresponding business logic layer server, and the business logic layer server forwards the business request to the corresponding job layer server, and the job layer server Realize the response to business requests and the provision of business services. [0003] As the data processing capacity of the...

Problems solved by technology

[0004] The inventor of the present invention finds out in research process: the quantity of each floor server of the server system after capacity expansion, and the multiple relation of the original quantity of each floor server of server system before capacity expansion, and the required data of server system after capacity expansion The relationship between the processing capacity and the multiple of the original data processing capacity of the server system is not the same, and there is no direct linear relationship; the existing data processing capacity required by the expanded server system has a multiple relationship with the original data processing capacity of the server system , the way of doubling the number of servers at each layer of the server system will lead to a relatively large number of server systems after expansion, and there will be redundant servers that cannot be used, resulting in a waste of server resources; therefore, how to reasonably Expanding the server system to reduce the waste of server resources in the server system after expansion has become a problem that those skilled in the art need to consider
