Abstract

A system is provided for migration of an application between processing servers in a virtual server. The system includes a first processing server, a second processing server, at least one disk for storage, at least one network interface, a control server and an agent. The control server is operable to combine the first processing server with the network interface and disk into the virtual server to operate an application. The agent is coupled to the control server to promote capture from the first processing server of application state information related to execution of the application by the first processing server. The agent further promotes transfer of at least some of the captured application state information to the second processing server to enable the second processing server to execute the application using the at least some of the captured application state information.

Claims20

Dependent claims

A system for migration of an application between processing servers in a virtual server, comprising:

a first processing server;
a second processing server;
at least one disk for storage;
at least one network interface;
a control server that combines the first processing server with the network interface and disk into the virtual server to operate an application;
and
an agent operably coupled to the control server that promotes capture from the first processing server of application state information related to execution of the application by the first processing server, the agent further promotes transfer of at least some of the captured application state information to migrate the application from the first processing server to the second processing server and enable the second processing server to continue the execution of the application using the at least some of the captured application state information, and the agent further promotes stopping the application processing on the first processing server,
wherein the captured application state information includes a first set of application state information that is recorded from the first processing server and is transferred for use by the second processing server while the application executes on the first processing server and while the second processing server is in operation, and a second set of application-related information captured after the first set of application state information, the second set of application state information including application state information that is recorded from the first processing server that changed since the first set of application state information was recorded and is transferred for use by the second processing server.

A system for migration of an application between processing servers in a virtual server, comprising:

a first processing server;
a second processing server;
at least one disk for storage;
at least one network interface;
a control server that combines the first processing server with one of the at least one network interface and one of the at least one disk into the virtual server to execute an application;
and
an agent that promotes migration of execution of the application from the first processing server to the second processing server during the execution of the application by capturing application state information from the first processing server and transferring the application state information for use by the second processing server while the second processing server is in operation, the agent further causes the first processing server to end the execution of the application and to enable the second processing server to continue the execution of the application about where the first processing server ended the execution of the application,
wherein the control server combines the one of the at least one network interfaces and the one of the at least one disk for storage into the virtual server with the second processing server instead of the first processing server to continue the execution of the application subsequent to transferring the application state information.
