Problems solved by technology

The deployment is complex, and the cluster requires at least 3 nodes
The multicast mechanism is adopted in the cluster, the larger the scale, the lower the efficiency
And currently, OpenStack does not have a set of complete monitoring, isolation and recovery solutions. Therefore, users must implement service monitoring and node isolation by themselves, and at the same time trigger the Evacuate operation on the faulty computing node

Abstract

The invention discloses a method and equipment for realizing high availability of a virtualized cluster. The equipment comprises an HA controller, a storage node, a DVS controller and a plurality of calculation nodes, the HA controller is used for monitoring the heartbeat of the host and making a decision and further controlling the overtime host; the calculation node is used for reporting and storing heartbeat information of a host and monitoring a virtual machine; the storage node is used for receiving and storing heartbeat through a storage network; and the DVS controller is used for controlling the virtual machine switch of each calculation node and performing management configuration of a network strategy. According to the method, the continuous service of the physical machine and the virtual machine can be ensured through rapid fault recovery, and the data safety is ensured through storage sharing.

Description

technical field [0001] The invention belongs to the technical field of virtualization, and in particular relates to a method and equipment for realizing high availability of a virtualized cluster. Background technique [0002] The application of virtualization technology can realize server integration, provide an independent, efficient and flexible operating environment for application systems, save resources and facilitate management. Server virtualization must have high availability (High Availability, HA) in order to form a stable and continuous basic platform. When the server or the virtual machine running on it fails, the application system will continue or briefly interrupt the service. [0003] The most common high availability solution is to use server cluster technology. High-availability clusters minimize the impact of software, hardware, or human-induced failures on the business by protecting the user's business programs to provide uninterrupted services to the ...
