A technique for mapping relationships among virtual elements across a system includes, for a server having a virtualized network interface controller (vNIC) with a plurality of vNIC links connected to a switch, identifying relationships between physical ports on the switch and virtual ports on the switch. For each vNIC link, local area network (LAN) interface information on the server is identified and data structures are created establishing topology information between the switch and the server. A mapping of each vNIC link to a respective virtual port on the switch is created by correlating the topology information with the LAN interface information.

Mapping relationships among virtual elements across a system

Techniques are disclosed for configuring a physical computing system (e.g., in a cloud computing network) to connect a network bond with a virtual multilayer switch. An operating system process executing in the physical computing system receives a selection of one or more network interfaces. The process aggregates the selected network interfaces into a bonded network interface having a first port. The process creates a network bridge having a second port. The process associates the first port with the second port. The process connects the network bridge with an integration bridge of the virtual multilayer switch via the second port.

A system for mapping relationships among virtual elements across a system includes a switch and a server having a virtualized network interface controller (vNIC) with a plurality of vNIC links connected to the switch. The system also includes a virtual relationship module configured to: identify relationships between physical ports on the switch and virtual ports on the switch; for each vNIC link, identify local area network (LAN) interface information on the server; create data structures establishing topology information between the switch and the server; and create a mapping of each vNIC link to a respective virtual port on the switch by correlating the topology information with the LAN interface information.

Establishing relationships among elements in a computing system, the computing system including one or more servers, one or more switches, the one or more servers and one or more switches forming one or more local area networks and also forming one or more virtual local area networks, including: identifying, for each server in the computing system, physical topology data; identifying, for each server in the computing system, virtual topology data; and creating, in dependence upon the physical topology data and the virtual topology data, a system map.

Establishing relationships among elements in a computing system

A method for managing cache elements in an environment based on Common Information Model is described. Cache elements in the cache are associated with a time attribute and historical data. Cache elements having a time attribute lying in a certain range are polled for from the server and updated at predetermined time points. A new time attribute is calculated for each cache element based on its historical data and this new time attribute assists in adapting the polling frequency for the cache element to its importance and change characteristics. Asynchronous notifications from the server preempt the polling based on the time attribute for a cache element and instead, polling for the cache element is based on the asynchronous notification. A system for cache management includes a client and a server, the client having a cache that is managed based on each cache element's importance and change characteristics.
