Patent number: 10526716Abstract: The invention relates to a method for producing a metal chalcogenide thin film electrode, comprising the steps: (a) contacting a metal or metal oxide with an elementary halogen in a non-aqueous solvent, producing a metal halide compound in the solution, (b) applying a negative electric voltage to an electrically conducting or semiconducting substrate which is in contact with the solution from step (a), and (c) during and/or after step (b) contacting the substrate with an elementary chalcogen forming a metal chalcogenide layer on the substrate. The invention also relates to a metal chalcogenide thin film electrode which can be produced by the method and its use as an anode for releasing oxygen during (photo)electrochemical water splitting.Type: GrantFiled: December 4, 2014Date of Patent: January 7, 2020Assignee: TECHNISCHE UNIVERSITAET BERLINInventors: Michael Lublow, Anna Fischer, Matthias Driess, Thomas Schedel-Niedrig, Marcel-Philip Luecke

Patent number: 9304798Abstract: A scalable, multi-tenant network architecture for a virtualized datacenter is provided. The network architecture includes a network having a plurality of servers connected to a plurality of switches. The plurality of servers hosts a plurality of virtual interfaces for a plurality of tenants. A configuration repository is connected to the network and each server in the plurality of servers has a network agent hosted therein. The network agent encapsulates packets for transmission across the network from a source virtual interface to a destination virtual interface in the plurality of virtual interfaces for a tenant in the plurality of tenants. The packets are encapsulated with information identifying and locating the destination virtual interface, and the information is interpreted by switches connected to the source virtual interface and the destination virtual interface.Type: GrantFiled: June 7, 2011Date of Patent: April 5, 2016Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Jayaram Mudigonda, Praveen Yalagandula, Jeffrey Clifford Mogul, Bryan Stiekes, Anna Fischer

Publication number: 20150135178Abstract: In one implementation, a host platform implemented on a computing device hosting one or more virtual machines determines that a communication generated by a virtual machine and intended for another virtual machine is to be transmitted to a network appliance. Consequently, the host platform modifies the communication generated by the virtual machine.Type: ApplicationFiled: March 8, 2012Publication date: May 14, 2015Inventors: Anna Fischer, Aled Edwards, Patrick Goldsack

Patent number: 8627313Abstract: A data center can share processing resources using virtual networks. A hosting program 9,10 hosts one or more virtual machines 11, 12. The program has a virtual interface VIF 1 14, to the virtual machines, a network interface 19 to enable communication between the virtual machines and other nodes of a network, and an infrastructure management interface 8, invisible to the virtual machines. The program has an intercept function 7 implemented as a comparator, switch or router, arranged to intercept a status message from one of the virtual machines, or applications run by that virtual machine. The status indication is sent to a status buffer 5 and is made available to the infrastructure management interface without providing a network path between the management interface and the virtual machine. This can discriminate between VM failure and communication failure, and the invisibility maintains isolation and helps avoid vulnerability to denial of service attack.Type: GrantFiled: March 9, 2009Date of Patent: January 7, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Aled Edwards, Anna Fischer, Patrick Goldsack

Patent number: 8370834Abstract: A data center can share processing resources using virtual networks. A virtual machine manager (10) hosts one or more virtual machines (11, 411), the virtual machines forming part of a segmented virtual network (34). Outgoing messages from the virtual machines have an intermediate destination address of an intermediate node in a local segment of the segmented virtual network, and the virtual machine manager has a router (18) for determining a new intermediate destination address outside the local segment, for routing the given outgoing message. By having the router as part of the virtual machine manager rather than having only a switch in the virtual machine manager, the need for virtual machines for implementing gateways is avoided. This can reduce the number of “hops” for the message between virtual entities hosted, and thus improve performance. This can help a service provider to share physical processing resources of a data center between different clients having their own virtual networks.Type: GrantFiled: March 9, 2009Date of Patent: February 5, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Aled Edwards, Anna Fischer, Chris I Dalton, Patrick Goldsack
