Virtualization based high availability cluster system and method for managing failure in virtualization based high availability cluster system
First Claim
1. A high availability cluster system comprising:
- a plurality of virtual nodes; and
a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node,wherein one of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of the virtual nodes included in the first physical node.

Abstract
Provided are a virtualization based high availability cluster system and a method for managing failures in a virtualization based high availability cluster system. The high availability cluster system includes a plurality of virtual nodes, and a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node. One of the virtual nodes not included in a first physical node among the plurality of the physical nodes takes over resources related to a service if a failure is generated in one of virtual nodes included in the first physical node.

3. A method for managing failure in a high availability cluster system comprising the steps of:
-
generating a message denoting that a plurality of virtual nodes are in a normal state, transmitting the generated message to virtual nodes in a same physical node, detecting a failure in a first virtual node in a first physical node; selecting one of the plurality of virtual nodes operated in a second physical node as a node for taking over resources related to a service through a failover process; and taking over resources related to the service through the selected virtual node. - View Dependent Claims (4, 5)
