Server dynamic expansion system and method

Abstract

The invention relates to a server dynamic expansion system and method. A load balancer monitors the load of a storage server, and sends an expansion request command to a management server when the load of the storage server exceeds a preset value. After receiving the expansion request instruction, the management server sends the expansion address information to the load balancer. The load balancer establishes a communication connection with the expansion server according to the expansion address information, and adjusts the load of the storage server to the expansion server. When it is detected that the storage server is overloaded, the load of the overloaded server is adjusted to the expansion server to avoid insufficient disk capacity of the server. When the server is expanded, it can avoid the impact on the normal operation and access of the website and users, and it can also reduce the restrictions on the server disk model and capacity, effectively alleviating the security risks brought by the server data during the expansion process. Operation The reliability is high, and the expansion method is simple and easy, which facilitates the dynamic expansion of the platform.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a server dynamic expansion system and method. Background technique [0002] With the popularization and continuous development of the Internet, the ever-increasing demand for access is increasingly testing the load capacity of the server. For a server, a large amount of data generated by users during use may cause insufficient disk capacity of the server. [0003] The traditional server expansion method is to add a new hard disk with a larger capacity, and copy the contents of the original disk to the new drive letter. A drop in website traffic. At the same time, the cost of adding a hard disk with a larger capacity is high, and there are also requirements for the hard disk model, and during the expansion process, the two disks cannot be taken offline, otherwise data will be lost. The traditional server expansion method has the disadvantage of low operational reliabi...

Problems solved by technology

For a server, a large amount of data generated by users during use may cause the problem of insufficient disk capacity of the server

[0003] The traditional server expansion method is to add a new hard disk with a larger capacity, and copy the contents of the original disk to the new drive letter. Decline in website traffic

At the same time, it is more expensive to add a hard disk with a larger capacity, and there are also requirements for the hard disk model, and during the expansion process, the two disks cannot be offline, otherwise data will be lost

The traditional server expansion method has the disadvantage of low operational reliability
