A data storage network is provided. The network includes a client connected to the data storage network; a plurality nodes on the data storage network, wherein each data node has two or more RAID controllers, wherein a first RAID controller of a first node is configured to receive a data storage request from the client and to generate RAID parity data on a data set received from the client, and to store all of the generated RAID parity data on a single node of the plurality of nodes.

A redundant processing fabric in an autonomous vehicle may include: processing, by a first processing unit of a plurality of processing units, sensor data from a first sensor of a plurality of sensors, where the plurality of processing units are coupled to the plurality of sensors via a switched fabric, wherein the plurality of processing units and plurality of sensors are included in the autonomous vehicle, wherein the sensor data corresponds to an environment external to the autonomous vehicle; determining a failure in processing the sensor data by the first processing unit; and severing, in the switched fabric, a first communications path between the first sensor and the first processing unit; and establishing, in the switched fabric, a second communications path between the first sensor and a redundant processing unit.

A method to avoid over-rebooting of a power supply device comprises Step 1: receiving a power-good signal generated by a power supply device working normally; Step 2: checking whether the power-good signal is received; if no, demanding the power supply device to reboot; and Step 3: recording a count of rebootings of the power supply device; after the power supply device reboots, checking again whether the power-good signal is received; if yes, letting the power supply device keep on working and resetting the count of rebootings; if no, demanding the power supply device to reboot again, accumulating the count of rebootings, and checking whether the count of rebootings is greater than a limited count of rebootings; if yes, forbidding the power supply device to reboot. Thus is solved the problem that a power supply device whose abnormality cannot be removed by rebooting may damage the information device.

A damage identification method for a redundant power supply system is disclosed. The redundant power supply system comprises a plurality of power supply devices and a control unit. In application of the method, the control unit respectively sends switching signals to the power supply devices to boot every power supply device. The control unit checks whether each of the power supply devices sends back a power state signal. If at least one power supply device does not sends back the power state signal, the control unit resends the switching signal to the power supply device to compulsorily reboot the power supply device, which does not output the power state signal. Thereby is solved the problem that the conventional technology cannot instantly exclude temporary abnormalities and causes the user to misjudge the failure of a power supply device.

An aspect includes coherency management between volatile memory and non-volatile memory in a through-silicon via (TSV) module of a computer system. A plurality of TSV write signals is simultaneously provided to the volatile memory and the non-volatile memory. A plurality of values of the TSV write signals is captured within a buffer of the non-volatile memory corresponding to a data set written to the volatile memory. Storage space is freed within the buffer as the data set corresponding to the values of the TSV write signals stored within the buffer is written to a non-volatile memory array within the non-volatile memory.

A data storage device and method for preventing data loss during an ungraceful shutdown are provided. In one embodiment, a data storage device is provided comprising a volatile memory; a non-volatile memory; and a controller. The controller is configured to detect an ungraceful shutdown; and in response to detecting the ungraceful shutdown: generate a reduced set of parity bits for data stored in the volatile memory, wherein the reduced set of parity bits comprises fewer parity bits than a full set of parity bits used in a graceful shutdown; and store the data and the reduced set of parity bits in the non-volatile memory. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Embodiments are generally directed to high capacity energy backed memory with off device storage. A memory device includes a circuit board; multiple memory chips that are installed on the circuit board; a controller to provide for backing up contents of the memory chips when a power loss condition is detected; a connection to a backup energy source; and a connection to a backup data storage that is separate from the memory device.

Apparatuses and methods for driving word driver lines in a gradual manner are disclosed herein. Word driver lines may be driven to intermediate potentials between high and low potentials. In some examples, the word driver lines may be driven in a step-wise manner. In some examples, the intermediate potential may be a bias voltage. The bias voltage may be provided by a bias voltage generator. One or more enable signals may be used to control the driving of the word driver line. In some examples, an address signal may be used to control the driving of the word driver line. Driving the word driver line in a gradual manner may cause a word line to discharge in a gradual manner in some examples.

A micro power outages compensation module for at least one server includes one or more capacitive storage element for storing electrical energy which is releasable for compensating the outages, the module further including a controller for the charging and/or the discharge of the capacitive storage element(s), limiting the charging and/or discharge current of the capacitive storage element(s) sufficiently to enable hot plugging and/or unplugging of the module even during operation of the server.

Systems, methods, and non-transitory computer-readable storage media for smart power clamping of a redundant power supply. A system configured according to this disclosure can measure, at a baseboard management controller, a system power consumption which indicates total power being delivered by a first power supply unit and a second power supply unit. The system can determine that the system power consumption exceeds a system power consumption capacity and, in response to the determination, communicate a power clamping signal to a processor, resulting in a reduced system power consumption. The system can further identify that the reduced system power consumption exceeds the system power consumption capacity and initiate a hardware throttling of at least one of the first power supply unit and the second power supply unit.
