Abstract: Aspects of dislocated charge storage for power loss protection in non-volatile memory systems are described. A system includes a power supply having an output power stage with bulk capacitance to supply power for a period of time after a power supply failure. The system also includes a network storage interface device and a non-volatile memory media card both coupled to the power supply for power. The power supply is configured to generate a power loss alert in response to the power supply failure. In turn, the network storage interface device is configured to perform a power loss data protection procedure with the non-volatile memory media card based on the power loss alert and during the period of time that the bulk capacitance can supply power after the power supply failure. The additional capacitance typically needed for power loss protection features is located apart from the non-volatile memory media cards.

Abstract: Systems and methods for handling resources in a computer system differently in certain situations, such as catastrophic events, based upon an assigned layer of the resource in the system. The layer can be based, for example, on criticality of the resource to the system. Services or devices can be assigned a criticality level representing a layer. The different layers can be treated differently in the case of an event, such as fire, a power outage, an overheating situation and so forth. In response to receiving information about such an event, the different layers can be handled in accordance with their criticality.

Abstract: A connection panel for enabling quick change over of a network device comprises a body and an engaging device. An exterior side of the body has multiple sockets, each of which can receive a plug connector. The panel is configured for positioning at one end of a rack space for the network device. The panel's interior side has first network device connections configured to mate with second network device connections on the network device. The engaging device has at least one member extending between the network device and the panel, and is repositionable between at least an engaged position in which the network device is moved towards and mechanically coupled to the panel with the second network device connections urged into engagement with and electrically connected to the first connections, and a disengaged position in which the network device is disengaged from the panel and removable from the rack space.

Abstract: Slidable electrical connection systems are described. An example system may include a compute component that may include a slide component and an elongate conductive structure disposed at an outer casing of the compute component. The slide component may permit the compute component to move linearly between an extended position and a stowed position. The elongate conductive structure is configured and positioned to engage with an electrical contact of a support surface to form an electrical connection. The electrical connection is maintained at least while the compute component is moved between the extended position and the stowed position.

Abstract: A network of interconnected circuit protection devices in a datacenter that can communicate over a network. Each circuit protection device can have a management component such that each device could know the state of every other device or a centralized management component could know the state of all devices. The states of the protection devices could include, fault or non-fault (e.g., high-current, current-imbalance and high temperature). Using this information, the management component(s) can prevent a single-device failure from triggering circuit-protection devices in other sections of the data center to open. The breaker logic can operate such that if a single device short-circuited and all devices upstream in the power delivery system sensed the short-circuit, then the lowest-level device would open and if the fault was still detected upstream, then the next level device would open.

Abstract: A controller may drive a first digital value onto a first address terminal of a first peripheral. The controller may transmit a data message on a data bus while driving the first digital value onto the selected address terminal. The first peripheral is coupled with the data bus, in accordance with at least one embodiment. A second peripheral having a second address terminal may also be coupled to the data bus. The first peripheral may be configured to accept the data message over the data bus when the first digital value is received on the first address terminal. The second peripheral may be configured to accept the data message over the data bus when the first digital value is received on the second address terminal.

Abstract: A power monitoring system monitors the actual configurations of power distribution systems which supply power to computer systems, based on data signals received at the computer systems via the power lines from the power distribution systems. The system determines if an actual power system configuration of a computer system is distinct from a target power system configuration of the computer system. A target configuration can be associated with particular computing operations performed on the computer system and can specify particular power system configurations of computer systems which execute such computing operations. The system can, in response to a determined distinction, adjustably control computing operation execution on the computer system, including adjustably routing data traffic. The system can, in response to a determined distinction, command power distribution system adjustments which mitigate the distinction.

Abstract: An expansion card mounting assembly includes a mounting structure and a circuit board coupled to the mounting structure. Expansion cards are mounted on a top side and a bottom side of the circuit board and secured at opposite ends by a moveable plate of the expansion card mounting assembly. The mounting structure includes an opening along a length of the expansion cards that allows air to flow over the expansion cards in multiple directions including a vertical direction. The moveable plate and mounting structure are configured to allow a position of the moveable plate on the mounting structure to be adjusted to mount expansion cards having different lengths in the expansion card mounting assembly.

Abstract: Cable-routing systems can be provided for a tray configured for movement between an extended position and a stowed position. The cable-routing system can include a biasing mechanism and a pivot. The pivot can receive a bend of a cable about the pivot. The pivot can be coupled with the biasing mechanism. Movement of the tray toward the extended position can pull the cable away from a stored state against a biasing force of the biasing mechanism. The cable can be biased into the stored state by the biasing force of the biasing mechanism when the tray is in or moved toward the stowed position.

The layer can be based, for example, on criticality of the resource to the system. Services or computing device resources can be physically segregated in accordance with layers and can be managed in accordance with the segregation. In response to receiving information about an event, the different layers can be handled in accordance with their criticality, for example by shutting some of the resources down and/or slowing some of the resources down.

The layer can be based, for example, on criticality of the resource to the system. Services or computing device resources can be physically segregated in accordance with layers, and can be managed in accordance with the segregation. As an example, critical layers can be fenced off or otherwise made not available except to users with secure clearance or authorization. In addition, a light or other indicator can be provided for indicating that a datacenter component is in a particular layer. The indicators can be at a device level, rack level, and/or room or area level.
