An aspect of the present disclosure facilitates performance of node management actions in a computing infrastructure having diverse node interfaces. In one embodiment, a configuration data is maintained, the configuration data specifying plugins designed to communicate with different node interfaces installed on the nodes of a computing infrastructure. The plugins are corresponding implementations of a common client interface. Upon receiving from the client application, via the common client interface, a management action to be performed on a desired node, the configuration data is inspected to identify a specific plugin corresponding to the node interface installed on the desired node. The node management action is then performed on the desired node using the identified specific plugin. Accordingly, the client application can be implemented agnostic to the specific node interfaces installed on a node.

Facilitating performance of node management actions in a computing infrastructure having diverse node interfaces

A system and method for updating a component of a virtual computing system in a hyperconverged system includes installing, by a processor executing computer-readable instructions stored on a memory of a lifecycle manager of the virtual computing system, a software package on a node of the virtual computing system for updating the component of the virtual computing system, and booting, by the processor, the component into an update environment based on the software package. The software package decouples a dependency of the lifecycle manager on the update environment. The system and method also include updating, by the processor, the component in the update environment and booting, by the processor, the component out of the update environment into an operating environment upon completion of the update of the component.

System and method for modularizing update environment in life cycle manager

One embodiment of the present invention provides a system. During operation, the system determines a first set of ciphers supported by a name server based on a name lookup response message. The system then inserts an entry associated with the name server in a data structure stored in a local storage device. Subsequently, the system identifies a second set of ciphers supported by a local name server in a name lookup query message destined to the name server. The system then selects the name lookup query message for an update operation based on the entry in the data structure. The update operation includes removing ciphers from the name lookup query message except a common cipher, which is present in both the first and second sets of ciphers. The system determines an egress port corresponding to the name server for the updated name lookup query message.

Efficient management of secure name lookup query messages

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.

Apparatuses and methods for remote computing node initialization using a configuration template and resource pools

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.

Apparatuses and methods for remote computing node registration and authentication

Techniques are provided herein for optimizing boot order for devices in a data center environment. These techniques may be embodied as a method, apparatus and instructions in a computer-readable storage media to perform the method. A computing apparatus having connectivity to a network receives instructions from a management device in the network. The instructions comprise attributes that are associated with boot devices hosted by the computing apparatus. The attributes are analyzed to determine a priority order for the boot devices. One or more boot devices hosted by the computing apparatus is removed from an initialization process when the one or more boot devices do not match the attributes in the instructions. The remaining boot devices, other than the one or more boot device removed from the initialization process, are initialized in accordance with the priority order.

Stateless flexible boot control

Presented herein are methods for budgeting power during a power-on self-test (POST) sequence. A determination is made for one or more stages of a power-on-self-test sequence of a system, whether a power profile of a particular stage is greater than a power budget for that stage. The power profile specifies a maximum power consumption as determined by the characteristics of the system and the power budget specifies a power consumption currently allocated to the system. When the power profile is greater than the power budget for that stage, power consumption of the system during the power-on-self-test sequence is limited such that the system does not consume more power than specified by the power budget.

Dynamically limiting bios post for effective power management

A method is provided in one example embodiment and includes logging in to a multipath target via first and second boot devices instantiated on a network device, the first and second boot devices respectively connected to the multipath target via first and second paths; determining which of the first and second paths comprises a least cost path; and booting the operating system via the least cost path. The determining may include comparing network statistics of the first path with network statistics of the second path, the network statistics comprising at least one of packet loss on the path, errors encountered via the path, and congestion on the path.
