Abstract: A configuration management system is configured to receive a registration request message from a computing node that includes identifying information, and to select a node pool in response to detection of a match between the identifying information matching a qualification parameter assigned to the node pool. The configuration management system is further configured to select configuration information for the computing node based on an image configuration template associated with the node pool. At least part of the configuration information is selected from a predefined resource pool. The configuration management system is further configured to provide the configuration information to the computing node.

Abstract: Examples described herein includes initialization of a computing node cluster. An example method providing a query request from an initialization application/service of a computing node for a default configuration management server identifier via a network, and receiving, from a network management server, an internet protocol address associated with the default configuration management server identifier. The example method further includes providing a configuration request from the computing node to the internet protocol address requesting configuration information, and receiving the configuration information at the computing node from a configuration management server associated with the internet protocol address.

Abstract: A computing node is configured to initialize by requesting a particular network resource from a network management server, and receiving acknowledgment of the particular network resource and an encryption key from the network management server to contact a configuration management server. The initialization further includes providing, using the particular network resource, a registration request message encrypted based on the encryption key to the configuration management server, and receiving configuration information corresponding to the computing node from the configuration management server in response to the registration request computing node.

Abstract: Examples described herein include imaging servers which may support asynchronous imaging of one or more computers (e.g., computing nodes). The imaging server may use out-of-band communication to install requested images on one or more computing nodes. The imaging server may support multiple concurrent installation sessions, and may maintain a log specific to each session. This may facilitate session-specific status reporting. In this manner, operating systems, hypervisors, or other software may be installed on computing nodes.

Abstract: A method of fabricating an optical device includes forming on a semiconductor substrate a first optical cavity, a second optical cavity, a first light guide and a second light guide. The first light guide has an input, and is optically coupled to the first optical cavity by a first coupling strength. In addition, the first light guide is optically coupled to the second optical cavity by a second coupling strength. The second light guide has an output, and is coupled to the second optical cavity by a third coupling strength. The first coupling strength is greater than the second coupling strength, and the third coupling strength is greater than the second coupling strength.

Abstract: An optical device includes first and second waveguides and a micro-ring. The first waveguide is optically coupled to the micro-ring and is separated from the micro-ring by a first gap having a first gap distance. The second waveguide has a supply port, an output port, and a coupling portion optically coupled to the micro-ring. The coupling portion is separated from the micro-ring by a second gap having a second distance. The second gap distance is larger than the first gap distance. The second waveguide and the micro-ring cooperate to form a filter having a stop band. The first gap distance is selected such that a first optical signal on the first waveguide having a first strength causes a first shift in the stop band such that a first wavelength is within the stop band, and wherein the second gap distance is selected such that a second optical signal on the second waveguide having the first strength causes a second or no shift in the stop band such that the first wavelength is outside of the stop band.
