REAL-TIME, DISTRIBUTED ADMINISTRATION OF INFORMATION DESCRIBING DEPENDENCY RELATIONSHIPS AMONG CONFIGURATION ITEMS IN A DATA CENTER

摘要

In a data center, real-time, distributed administration of information describing dependency relationships among configuration items may be carried out. In such a data center, each configuration item is associated with an independent agent that is coupled to other agents and maintains a record of dependencies amongst the configuration item associated with the agent and other configuration items. Administration of dependency information includes: detecting, by an independent agent associated with a particular configuration item, a change in the item's dependency; providing information describing the change in the particular configuration item's dependency to all other independent agents associated with configuration items that are in a dependency relationship with the particular configuration item; and, for each of the other independent agents associated with configuration items that are in a dependency relationship with the particular configuration item: updating the record of dependences for the configuration item associated with the independent agent.

主权项

1. A method of real-time, distributed administration of information describing dependency relationships among configuration items of a data center, each configuration item of the data center associated with an independent agent, the independent agents coupled to one another for data communications, each independent agent maintaining a record of dependencies amongst the configuration item associated with the independent agent and other configuration items of the data center, the method comprising:
detecting, by an independent agent associated with a particular configuration item, a change in the configuration item's dependency, including updating a record of dependencies for the particular configuration item; providing, by the independent agent associated with the particular configuration item, information describing the change in the particular configuration item's dependency to all other independent agents associated with configuration items that are in a dependency relationship with the particular configuration item; and for each of the other independent agents associated with configuration items that are in a dependency relationship with the particular configuration item: updating, by the independent agent, the record of dependences for the configuration item associated with the independent agent.
