SERVER SYSTEM AND CLUSTER SYSTEM USING THE SAME

摘要

A server system and cluster system using the same. The server system includes power supply module for providing first operation power, an energy-storing module for providing a stored power, power management module coupled to power supply module and energy-storing module for receiving first operation power and providing a second operation power, or for receiving the stored power and providing a third operation power, at least one motherboard having internal memory module for receiving second operation power or third operation power, and an external memory module coupled to the at least one motherboard. The present invention retains the data in the memory and the operating messages while a power failure occurs suddenly in the server so that server system is capable of restoring the data and the operating messages before the power failure to simplify the system and reduce the cost.

1. A server system, comprising:
a power supply module, for providing a first operation power; an energy-storing module, for providing a stored power; a power management module electrically coupled to the power supply module and the energy-storing module, either for receiving the first operation power to provide a second operation power or for receiving the stored power to provide a third operation power; at least one motherboard comprising an internal memory module, for receiving either the second operation power or the third operation power; and an external memory module electrically coupled to the at least one motherboard; wherein when the server system operates normally, the power management module transforms the received first operation power into the second operation power to be provided to the at least one motherboard, when the server system is powered off abnormally, the power management module instantly changes the received first operation power to the stored power to transform the stored power into the third operation power, and the third operation power is provided for a time interval “T”; and wherein during the time interval “T”, a data backup module installed in an operating system is used to backup data of the internal memory module and an operation task to the external memory module while the data backup module interrupts an electrical connection between the energy-storing module and the power management module, and when the server system powers on again, the data backup module restores the data in the external memory module and operation tasks to the internal memory module so that the server system returns a normal status before the server system is powered off abnormally.
