A method and apparatus is provided wherein a server is powered by a battery connected to a charging circuit. The voltage output by the battery is monitored and when it falls below a threshold, a determination is made that the battery is being depleted. In response to the determination, the server is brought into a reduced power consumption state or a data saving state.

Battery state detection by use of voltage in a shared power system background

Disclosed are ways to flexibly arrange, rearrange, and execute optimization modules for program code in user-customizable sequences. In various embodiments, computer programmers can select an order of multiple standalone optimizers that each perform an optimization function on program code, forming a pipeline of a series of optimization modules. The pipeline can be modified by, for example, adding, removing, rearranging, repeating, and/or replacing optimization modules.

Rearrangeable code optimization modules

A system and method is provided where, in one aspect, the system and method provide access to one or more devices located on a server. Each device may be physically connected to a controller. The controller may include a plurality of agents each configured to provide access to a device at a unique ephemeral port. The controller may include a registry that stores mapping information between the agents and the ephemeral ports. Applications running on the controller or running on a client may access the registry for port information of a given agent or a given device via a predetermined port.

Ephemeral port registry/device discovery

Aspects of the disclosure relate generally to uninterruptible power supply units for systems requiring back up power. Each unit may include UPS circuitry for controlling charging and allowing discharging of a battery. The UPS circuitry may includes a controller and a plurality of metal-oxide semiconductor field effect transistors ('MOSFET') switches. The MOSFETs may include charging and discharging MOSFETs arranged in series with the battery all driven by a single gate driver, such as a controller. In this regard, the controller may limit the charging current though all of the MOSFETs and charge the battery. The MOSFETs may be arranged such that if the charging MOSFET fails, the redundant charging MOSFET may continue to limit the charging current to the battery. Similarly, a redundant discharging MOSFET may be arranged in series with a discharging MOSFET in order to continue to provide discharging current if the discharging MOSFET fails.

Redundant charging and discharging MOSFET driving in battery backup system

An apparatus for managing telemetry sensor controllers identified by their communication port identifiers is disclosed. The apparatus may include a memory that stores telemetry sensor controller mappings, where a telemetry sensor controller mapping associates an equipment identifier for a telemetry sensor controller with a communication port identifier, and equipment identifier mappings, where an equipment identifier mapping associates an equipment identifier with a telemetry monitoring application. The apparatus may detect a connection with a telemetry sensor controller and receive an equipment identifier. The apparatus may then instantiate a telemetry monitoring application for managing the connected telemetry sensor controller by accessing the plurality of equipment identifier mappings with the received equipment identifier, where the telemetry monitoring application may instruct the connected telemetry sensor controller to perform a requestable operation.

Instantiating an application based on connection with a device via a universal serial bus

An apparatus and method for initializing electrical devices based on a voltage level. The voltage level may be modified to a particular setting based on the availability of power supply components, such as AC to DC rectifiers. Depending upon the availability of the power supply components, a control system may alter output voltage to a particular level. The components receiving power may be coupled to voltage dividers, where the voltage dividers are configured to modify an input voltage to cause or prevent the input voltage from rising above an initialization level for the particular component. The output voltage may be set by the control system such that a number of components that experience a voltage rise above an initialization threshold correspond to the number of available power supply components.

System and method for voltage controlled initialization

A method and apparatus are provided for controlling the operation of a data center wherein a computer cluster, managing terminal, and an interface device are deployed to control the operation of a data center component. The computer cluster, managing terminal, and the interface device take turns in controlling the operation of the data center component in dependence upon changes in the state of a the data center component, or changes in the states of various other groups of data center components. Objectives for the data center may be broken down into sub-objectives to be performed by portions of the data center.

Mixed-mode data center control system

An apparatus for providing telemetry information of monitored equipment is disclosed. The apparatus may store a first set of application mappings and a second set of application mappings. The first set of application mappings may be established when equipment to be monitored is connected to the disclosed apparatus. When connected, the processor of the disclosed apparatus may instantiate a monitoring application, which may request a communication port number for communicating telemetry information received from the equipment to be monitored. The application mappings may store an association of the instantiated application and its corresponding communication port number. The apparatus may also establish a common communication interface for communicating with the various monitoring applications based on the stored application mappings. Thus, a client device need only communicate with the common communication interface instead of each of the monitoring applications separately.

Proxy reporting for central management systems

A method and apparatus are provided for updating software one or more control devices in a data center. According to the method and apparatus a data center is outfitted with a plurality of control devices responsible for controlling the operation of a data center component. An update server is configured to update software running one of the plurality of control devices whenever software running on another one of the plurality of control devices is updated.

Updating control devices in a data center

A method and apparatus is provided for identifying ports on a power distribution board. In one aspect, the power distribution board is configured to output a plurality of signals from a plurality of ports, so that each of the output signals is different with respect to at least one signal characteristic from the other signals. In another aspect a table is provided that relates port identifiers to values of the signal characteristic. A server measures the value of the signal characteristic for a signal that is fed to the server by the power distribution board and identifies the port that outputs the signal by consulting the table.

Identifying power ports of a power distribution board

An apparatus for managing telemetry sensor controllers identified by their respective communication port identifiers is disclosed. The apparatus may include a memory that stores a telemetry sensor controller mapping that associates an equipment identifier for a telemetry sensor controller with a communication port identifier, an equipment identifier mapping that associates an equipment identifier with a telemetry monitoring application, and a firmware mapping that associates a telemetry monitoring application with a firmware for a telemetry sensor controller. The apparatus may determine an equipment identifier for a connected telemetry sensor controller and instantiate a telemetry monitoring application for the connected telemetry sensor controller based on the equipment identifier mapping. The apparatus may then automatically transfer a firmware to the connected telemetry sensor controller when the firmware version installed on the connected telemetry sensor controller is determined to not be a current version of the firmware available.
