Abstract: A storage target comprising a computer memory configured with storage provisioning parameters and a map of initiator information to the storage provisioning parameters. The storage target is configured to receive a discovery request from a requesting initiator, extract identifying information from the discovery request, determine a set of storage provisioning parameters to which the requesting initiator maps based on the extracted identifying information and the map of initiator information to storage provisioning parameters, dynamically create a new virtual target for the requesting initiator according to the set of storage provisioning parameters, dynamically create a storage partition from storage space of a plurality of storage devices according to the set of storage provisioning parameters, assign the storage partition to the new virtual target and return information about the new virtual target to the requesting initiator to allow the requesting initiator to connect to the new virtual target.

Abstract: A cooling arrangement for a server mountable in a server rack comprises a phase change device and a fluid cooling unit. The phase change device includes an evaporator mountable on a heat-generating unit of the server, a condenser disposed outside of the server, and conduits extending laterally from the server, between the evaporator and the condenser. The conduits carry a working fluid heated in the evaporator to the condenser. The working fluid is cooled in the condenser before returning to the evaporator. The fluid cooling unit is positioned along the server rack and receives a cooling fluid from an external cooling facility. A heat transfer module of the fluid cooling unit has an open channel for slidably receiving the condenser. The cooling fluid flows in a water jacket surrounding the open channel. Heat is transferred from the condenser to the cooling fluid flowing in the water jacket.

Abstract: Methods and systems are described for performing a migration from source networking devices to replacement networking devices. A simulation may be performed of the migration from the source devices to the replacement devices. The simulation may be used to determine whether to proceed with the migration. A technician may be instructed to perform the migration. A verification may be performed to determine whether the migration was successful. The source devices may be decommissioned.

Abstract: A circuit comprises an output connector connectable to a load. A relay selectively connects the output connector to an AC power source. The relay is responsive to a disabling signal to disconnect the output connector from the AC power source. A sensor senses a level of power delivered to the load via the output connector. A detector emits a first fault signal when the sensed power level exceeds a fixed power limit. A latch maintains the first fault signal until it receives a rearm signal. A controller emits a second fault signal when the sensed power level exceeds a configurable power threshold, receives a user command to rearm the circuit, and in response to receiving the user command, emits the rearm signal and ceases the emission of the second fault signal. A logic combiner generates the disabling signal when it receives one of the first and second fault signals.

Abstract: Methods of and systems provide service redundancy between a master server and a slave server. The master server provides access to a pool of resources to a client. In response to detecting a fault on the master server, the master server is marked as disabled and services held on the master server are switched to the slave server and to a secondary pool of resources. The master service may be restarted if down. Then, provided that the master server is up, one or more tests are performed on the master server. The master server is marked as enabled if the tests are successful. The services may be switched back to the master server when the server is enabled. Services may further be rolled back to the slave server in case of an additional fault occurrence. The technique may also be used for updating a configuration in a service infrastructure.

Abstract: A method of positioning a rack onto a base structure is provided. The rack includes a support member for supporting the rack on the base structure. The method includes: affixing a positioning tool to the base structure; aligning a guiding opening defined in the support member of the rack with the positioning tool affixed to the base structure; lowering the rack onto the base structure such that the guiding opening receives the positioning tool therein; and removing the positioning tool from the base structure once the rack is in a desired position atop the base structure.

Abstract: A method of preventing disjunctions in a power distribution unit having a plurality of output connectors is disclosed. A power level of each of the output connectors is sensed. It is detected that the power level of a given output connector exceeds a fixed power limit. In response to the detection, a delivery of power by the given output connector is stopped while maintaining a delivery of power by a remainder of the output connectors. Power delivery may be resumed in response to receiving a user command to rearm the given output connector. A power distribution unit adapted to prevent disjunctions is also disclosed.

Abstract: A circuit comprises a primary transistor connecting a primary voltage source to a load connector. A translator and a secondary transistor cause opening of the primary transistor when receiving an off command and cause closing of the primary transistor when receiving an on command. The secondary transistor is powered by a secondary voltage source. A microcontroller receives measurements of a load voltage at the load connector. The microcontroller detects a drop of the load voltage to determine a moment when the load becomes connected to the circuit while the off command is being issued. The microcontroller issues the on command in response to the determination. Successive brief on commands may be issued to initially control current build-up in the load. A system includes the microcontroller and a plurality of such circuits for powering plural loads.

Abstract: A circuit includes a voltage source, a transistor, a load current sensor, a hardware latch and a logic circuit. The transistor is connected between the voltage source and a load. The sensor emits a fault signal when the load current exceeds a predetermined value. The hardware latch sets a latch signal when it receives the fault signal and maintains the latch signal until it receives a rearm signal. The logic circuit receives the latch signal from the hardware latch and also receives a software command for controlling turning on and off of the circuit. When the latch signal is not set, the logic circuit converts the software command to a control voltage applied at a gate of the transistor, turning on the transistor to allow power delivery to the load. A system includes a microcontroller providing software commands and rearm signals to a plurality of circuits.
