Dual system image deployment in a cluster of servers

摘要

The method involves installing and configuring a reference computer (1000), and recording an image of the computer (1010) on a storage unit, where the image has a copy of system of reference files and hardware setting instructions. A standard deployment message of the image is emitted (1020) toward nodes by a supervisor. Deployment of image is restarted and executed in accordance with the message by micronucleus. Tools are installed for deployment of another image during the configuration. Creation instruction of an additional partition is added to the instructions during the recording. An independent claim is also included for a digital storage device comprising a file corresponding to instruction codes to implement a method for deploying an image on nodes of a bunch of computers.
