Patent ID: 8381007

Claim:
A data storage system with power backup mechanism, comprising: N power supply modules, wherein each of the N power supply modules generates a presence signal, a warning signal and a state signal, and N is an integer greater than 1; N programmable logic devices, wherein each of the N programmable logic devices is connected to the N power supply modules and configured to receive N presence signals, N warning signals and N state signals generated from the N power supply modules respectively, each of the N programmable logic devices configured to convert N presence signals, N warning signals and N state signals into a converted first presence signal, a converted second presence signal, a converted first warning signal, a converted second warning signal and a converted state signal; a storage server connected to the N programmable logic devices and configured to receive N converted first presence signals, N converted second presence signals, N converted first warning signals, N converted second warning signals and N converted state signals from the N programmable logic devices respectively, wherein the storage server is configured to output two power condition signals according to N converted first presence signals, N converted second presence signals, N converted first warning signals, N converted second warning signals and N converted state signals; and a control module connected to the storage server and configured to monitor a power condition of the N power supply modules according to the power condition signals.
