Abstract: A decentralized certificate module generates a unique key pair. The decentralized certificate module creates a certificate signing request (CSR) based at least on a public key of the unique key pair. The decentralized certificate module signs the CSR with pre-installed system data to generate a signed trust certificate. The decentralized certificate module initiates a secure communication that includes the signed trust certificate.

Abstract: Systems and methods are described for controlling inrush current for a system comprising a plurality of metal-oxide-semiconductor field-effect transistors (MOSFETs). The system may include a control circuit coupled to parallel series of gate drivers, where each gate driver is coupled to a different MOSFET. An inrush current may be received during charging of a capacitor of the switch circuit. During a first period of a ramp time, the control circuit may cause the inrush current to pass through a first gate driver. During a second period of the ramp time, the control circuit may cause the inrush current to pass through a second gate driver. By using a control circuit to cause the inrush current to pass through each MOSFET, a gate-source threshold voltage for the MOSFETs may remain below safe operating areas (SOAs) for the different MOSFETs.

Abstract: A system and method for controlling cooling in a computing device are provided. A measurement of power consumption of at least one of the computer components is received. A theoretical setting for the cooling system is determined based on the received measurement of power consumption. A current setting of the cooling system is identified. Based on a difference between the theoretical setting and the current setting, a next setting for the cooling system is determined. An output of the cooling system is controlled based on the next setting for the cooling system.

Abstract: An apparatus for bracing a face of a computer rack includes a brace mountable by hinges to one side of the face of the computer rack. A latch is mountable to the other side of the face of the computer rack. When the brace is closed against the face of the rack, the latch may be closed to capture elements of the brace and thereby provide rigidity to the face of the computer rack.

Abstract: An expansion device is disclosed for including a plurality of modular devices within a pre-defined volume, such as the drive bay of a computing device. The expansion device may include a standardized bus connection and circuitry connecting to a controller chip, circuitry electrically coupling the controller chip to a plurality of modular devices, and a housing that houses the controller chip, connecting circuitry, and modular devices and that fits within the pre-defined volume.

Abstract: A multilevel rotating drive carrier includes stacked top, middle, and bottom drive-holding brackets. The top and middle brackets pivot about a parallel axis from a closed position to an open position to provide access to middle and bottom storage drives. The top bracket makes a storage drive accessible when the carrier is closed or open. Removing one storage drive does not require the disconnecting of another storage drive.

Abstract: An apparatus for securing a cable access includes a first cable opening in a top plate of a server rack with a tray affixed to the interior side of the top plate and with a second cable opening that overlaps the first cable opening. A hatch element is movable in a space between the plate and tray to cover up the unneeded areas of the first and second cable openings after cables have been installed. A ratchet and pawl attached to the tray and hatch element cooperate to allow movement of the hatch element in a closing direction and resist movement of the hatch element in an opening direction, with a release element disengaging the ratchet and pawl to allow the hatch element to open.

Abstract: A ducting apparatus, switch, and rack of electronic devices are disclosed in which the ducting apparatus is configured to convey air from a cold aisle at a first face of the rack to a side air inlet of the switch. The ducting apparatus also hinders or prevents exhaust air from the switch from reaching the cold aisle.

Abstract: A carrier for securing a computer drive within a chassis facilitates the removal and installation of the computer drive in the carrier by using pins to engage the mounting holes of a computer drive.

Abstract: A rack test room is disclosed that provides a controlled and monitored environment for one or more server racks, the room controlling and monitoring the cold aisle temperature, the cold aisle air inlet flow rate, and the hot aisle temperature. A rack test room is disclosed that monitors the inlet and exhaust air temperatures for each server in a rack. A rack test room is disclosed that individually controls and monitors the inlet air flow rate to each of a plurality of server racks. A method is disclosed for using a rack test room to simulate a data center environment.

Abstract: A heat sink is disclosed in which a set of fins dissipates heat, where the heat is conducted from a heat source to two sides of the set of fins by a vapor chamber assembly. In an embodiment, a thin vapor chamber assembly is configured to conduct heat to both the bottom and the top of a set of fins. In an embodiment, a thin vapor chamber assembly is configured to conduct heat to a lower set of fins and also to an upper set of fins.

Abstract: A system and method for controlling cooling of computer components of a computing device are provided. A measurement of power consumption of at least one of the computer components is received. An amount of heat expected to be generated by the at least one computer components is determined based on the received measurement of power consumption. An output of a cooling system of the computer components is controlled based on the determined amount of heat expected to be generated.

Abstract: A rack door is disclosed for mounting one or more power distribution units (PDUs) to the front of a server rack. An embodiment allows access to power cables when the rack door is open or closed. An embodiment provides power cable routing that allows power cables from one PDU to be connected or disconnected independently from other cables on that same PDU or on another PDU mounted to the rack door.

Abstract: An HDD mounting apparatus for installing HDDs into a server device is disclosed. The mounting apparatus includes frame dimensioned to receive an HDD and fit within a drive bay with a connector positioned inside for connecting to the HDD. A top cover is secured to one of the long sides of the frame and provides a slot within which a sliding mechanism travels linearly. The sliding mechanism has an engagement mechanism to engage with an edge of the drive bay. A lever is rotatably connected to the top cover by a first hinge. A connector arm is further connected to the lever at one end, and to the sliding mechanism at a second end. When the lever is rotated in one direction, the connector arm generates a force on the sliding mechanism in the first direction that is transferred to a force on the frame in a second opposite direction.

Abstract: A carrier is disclosed for securing a computer drive within a chassis. The carrier provides improved access to the computer drive and drive connector using a lever and lifting pins. The lever and pins cooperate to lift the computer drive and the lifted access allows such carriers to be positioned with minimal separation, increasing the potential density of computer drives within the chassis. The lifted access also assists with computer drive maintenance.
