FAILOVER METHODS AND SYSTEMS FOR A VIRTUAL MACHINE ENVIRONMENT

摘要

A storage provider executing a plurality of Web servers is provided for receiving a request from a management console managing a plurality of virtual machines. The management console uses a same address to send the request, regardless of which Web server is selected to process the request. The selected Web server re-sends the request to a second storage provider node instance, when a first storage provider node instance fails to process the request, where the first and the second storage provide node instances are executed by the storage provider as virtual machines for providing failover in processing requests.

1. A machine implemented method comprising:
receiving a request at a storage provider interfacing with a storage system that maintains storage space and a management console; wherein the request is a management request associated with management of the storage space; assigning the request to a Web server from among a plurality of Web servers executed by the storage provider; sending the request to a first storage provider node instance executed by the storage provider from among a plurality of storage provider node instances; re-sending the request by the Web server to a second storage provider node instance when the first storage provider node instance fails to execute the request; and executing the request by the second storage provider node, while the management console is unaware as to which storage provider node executes the request.
