A method of representing and managing hierarchical relationship configuration in a computing facility is described. The method includes providing and storing a first index of hardware identifier assigned to each object in the computing facility; providing and storing a second index of ancestry identifiers of each object in the computing facility, the ancestry identifier of an object being the hardware identifier of an ancestor object at 1 to n hierarchy levels above the object; providing and storing a type information element for each ancestor object indicative of a type of ancestor object; and identifying an ancestor object of a particular object in the computing facility by accessing the first index of hardware identifier of the particular object; and identifying an ancestor object thereof of a particular typed by accessing the ancestry identifiers and the type information element of the particular object.
