A method and device for automatically switching a faulty computer

Abstract

The invention provides a fault computer automatic switching method and device. The method comprises following steps: according to the computer performance and / or computer features demanded by the application programs operated on computers, grouping all computers in a private cloud environment to obtain multiple host groups; monitoring the operation states of all computers in the private cloud environment in real time; when a downtime computer is monitored, searching an idle computer in the host group to which the downtime computer belongs, transferring the application programs operated on the downtime computer to the idle computer to be operated. Through using the method of the invention to switch the fault computer, the computer in accord with the demand can be selected; manually selecting the computer is unnecessary, therefore, the operation and maintenance difficulty is reduced, the manpower is saved, and the interrupted time of the application program service on the downtime computer is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for automatically switching a faulty computer. Background technique [0002] Cloud computing is an innovative IT application model, which abstracts a large number of server hardware into a huge resource pool through hardware virtualization, and can dynamically provide users with services in three forms: infrastructure, platform and application. [0003] A private cloud is built on the basis of an enterprise's own facilities and built for the sole use of an enterprise customer, thus providing the most effective control over data, security, and service quality. The enterprise owns the infrastructure and controls how applications are deployed on this infrastructure. More importantly, many enterprises have already established relatively complete hardware facilities before establishing a private cloud. Although the performance and characteristics of the hardware...

Problems solved by technology

[0008] However, the above two device switching schemes have the following defects: scheme (1) due to the random selection of computers, it is impossible to ensure that a computer that meets the computer characteristics requirements of the application program that needs to be migrated can be selected. On a computer with a mega-network card, if a randomly selected computer only has a normal network card, it will inevitably affect the application service quality

Solution (2) requires manual computer selection, which not only wastes manpower while increasing the difficulty of operation and maintenance, but also inevitably increases the time for application service interruption on the downtime computer
