Abstract: A power over Ethernet (PoE) powered device with power fallback states. A powered device can be powered using a primary local power source and a secondary PoE power source. To enable consistent behavior by the powered device, a controlled power fallback state can be defined that would ensure limited functionality in the powered device upon a failure of the primary local power source. For example, the limited functionality could include a communication channel to the switch, diagnostic circuitry, etc.

Abstract: An in-vehicle apparatus includes: a flash memory; a memory controller for executing an initialization process; a backup power source; a power source; a controller; and a power source controller. According to incompletion of initialization, the controller executes standby/boot process. According to completion of initialization, the controller executes the boot process. According to reception of data backup instruction, the controller stores data in the memory. The power source controller switches to a trigger standby mode. According to trigger, the power source controller inputs the energization instruction to the power source. According to termination of trigger, the power source controller inputs the data backup instruction to the controller. According to completion of backup, the power source controller halts to input the energization instruction, and switches to the trigger standby mode. According to incompletion of backup, the power source controller resets the switch and the power source.

Abstract: In general, embodiments of the present invention provide an approach for direct memory access (DMA) without main memory for a semiconductor storage device (SSD)-based system. Specifically, in a typical embodiment, an input/output hub (IOH) is provided with an inter-DMA engine. The IOH is coupled to a central processing unit (CPU), a set of double data rate (DDR) SSD memory disk units, and a graphics card. The graphics card can comprise a cache memory unit or other type of memory unit. Among other things, this embodiment provides one or more of the following features: interchangeability of hardware; resource allocation for DMA in the CPU utilizes inter-DMA resources; direct data transfer to the graphics card/processor; and/or no need to depend on a main memory comment needed in previous approaches.

Abstract: A method is disclosed for balancing the requirements of high availability achieved by redundant active components and power saving achieved by less active components. The requirement for high availability can be expressed by the recovery time objective (RTO) which specifies the amount of time it takes to recover from a failure in the system. Based on the configured RTO, the system configures the most appropriate power mode.

Abstract: A storage system comprises multiple physical storage devices, and a power supply for the multiple physical storage devices. Each physical storage device requires an input of a first voltage and an input of a second voltage that is a lower voltage than the first voltage. The power supply comprises a first power supply circuit that is made redundant and a second power supply circuit that is made redundant. Each first power supply circuit outputs a first voltage, which is input to the respective physical storage devices. Each second power supply circuit outputs a second voltage to a storage device group (two or more physical storage devices of the multiple physical storage devices) corresponding to this second power supply circuit. Each second power supply circuit is isolated from a circuit board comprising the first power supply circuit.

Abstract: A method of operating a storage system comprises detecting a cut in an external power supply, switching to a local power supply, preventing receipt of input/output commands, copying content of cache memory to a local storage device and marking the content of the cache memory that has been copied to the local storage device. When a resumption of the external power supply is detected, the method continues by charging the local power supply, copying the content of the local storage device to the cache memory, processing the content of the cache memory with respect to at least one storage volume and receiving input/output commands. When detecting a second cut in the external power supply, the system switches to the local power supply, prevents receipt of input/output commands, and copies to the local storage device only the content of the cache memory that is not marked as present.

Abstract: In a method for detecting power statuses of one or more power supplies in an electronic device. The method detects a power status of each power supply at a first time cycle when a baseboard management controller (BMC) of the electronic device is started up, and stores all the detected power statuses into the BMC. The method determines a change value of the power status of each power supply at a second time cycle by analyzing the detected power statuses of each power supply stored in the BMC, and stores the change value of the power status of each of the power supplies in the BMC.
