Power share controller for providing continuous system peripheral bay access between at least two data processing systems on a data network with no interruption to peripheral bay operation

摘要

A data processing system such as a server system connected to a data network having a network peripheral bay access feature that enables another server system on the same data network to have access to the system peripheral bay with no operating interruption, when the system main baseboard is disabled. An exemplary server system includes a system peripheral bay supporting at least one peripheral device; a system main baseboard supporting at least one main processor; and a power share board supporting a power share controller for controlling power voltages supplied to the system peripheral bay and the system main baseboard, including automatically switching off electrical connection between the power share board and the system main baseboard when the system main baseboard is disabled, while maintaining the electrical connection between the power share board and the system peripheral bay for peripheral bay operation to enable another server on the same data network to have access to the system peripheral bay with no operating interruption.
