SYSTEM AND METHOD FOR PROVIDING A COMPUTER STANDBY NODE

摘要

An apparatus for providing a computing environment in a computing system includes a first node, a second node, an operations server, and a communication link. The first node is capable of supporting a production computing environment and 5 has a first disk storage. The second node is capable of supporting a second operational computing environment, independent of the production computing environment and has a second disk storage.;A method of switching a production computing environment from a first node, having a first disk storage, to a second node in the event of a failure on the first 15 node includes determining if the first node had a failure and if the first node had a failure: reassigning ownership of the partition definition to the second node; restoring communications configuration on the second node; and booting the second node from the first disk storage.

1. An apparatus for providing a computing environment in a computing system, the apparatus comprising:
a first node capable of supporting a production computing environment and having first disk storage; a second node capable of supporting a second operational computing environment, independent of the production computing environment, and having second disk storage; an operations server that manages the first and second node and that can switch the production computing environment from the first node to the second node; and a communications link between the first node, the second node, and the operations server; wherein the operations server can cause the second node to take over the production computing environment from the first node upon a failure of the first node by providing the second node with access to the first disk storage and rebooting the second node from the first disk storage.
