ABSTRACT:
An information handling system includes first and second servers in communication with shared storage. The shared storage may include a shared operating-system storage subdivision containing unmodified operating system data, as well as first and second delta storage subdivisions containing operating-system data configured for the first and second servers, respectively. The information handling system may also include one or more delta drivers that use the shared operating-system storage subdivision and the first and second delta storage subdivisions to provide first and second virtual storage subdivisions for booting first and second instances of an operating system, where each instance may be configured differently for each server. For example, for operations from the first server involving modified and unmodified portions of the first virtual storage subdivision, the delta driver may automatically access the first delta storage subdivision and the shared operating-system storage subdivision, respectively.
