Abstract: A method of preventing data loss in a data storage system includes supplying write data to a high speed volatile write buffer and supplying electrical power from an energy storage device upon detection of a primary power loss event. The backup electrical power is supplied to the write buffer and nonvolatile cache. Under backup power, the write data is transferred into the nonvolatile cache and the backup power is removed.

The method may be implemented for a system to protect it from inadvertent power losses or it may implemented in a system where the long term storage device is power cycled to save power. The energy storage device is not necessarily needed in the power cycled system unless power failure protection is also desired.

Abstract: It is possible to apply a correct power to a load even when the output impedance and a load impedance of a signal source are different from a characteristic impedance of a transmission line. The power applied to the load can be expressed by a measurement system error factor, a load coefficient X of the load, and an S parameter of the input signal R. Accordingly, a target input signal decision can decide a target value of the S parameter of the input signal R according to the power desired to be applied to the load, the measurement system error factor, and the load coefficient X of the load. Furthermore, an input signal level control section controls the input signal level so that the S parameter of the input signal R has this target value. This is performed by changing the amplification ratio of an amplification ratio variable amplifier. Thus, it is possible to apply a desired power to the load not depending on whether the impedance is matched or not.

Abstract: A storage apparatus according to the present invention can store information related to a power supply abnormality after shutting down the principal functions of a data processing board when a power supply abnormality occurs in a data processing board. A power supply controller of a data processing board mounted in the storage apparatus monitors the operational status of DC/DC power supplies mounted to the data processing board, on the basis of detection signals from a voltage detection circuit.

Shutting down the DC/DC power supplies also shuts down the principal functionality of the data processing board. Then, after storing information related to the power supply abnormality in memory, the power supply controller shuts down the auxiliary power supply.

Abstract: When causing a power saving mode to return by inputting a return signal, power is supplied to a device to which suppliance of power has been cut off. In this case, a power-saving control CPLD is masked to cancel an uncertain signal generated in the device under an intermediate potential at which the voltage of a power-saving-time power cutoff device, which supplies power to the device, is gradually rising. Thus, an erroneous operation caused by the uncertain signal can be prevented. Further, when the voltage of the power-saving-time power cutoff device reaches an operation-guaranteeing voltage, the power-saving control CPLD reads the uncertain signal again. Thereby, intrinsic characteristics of the uncertain signal can be verified, and a secure return operation can be implemented.
