vSphere Inventory Structure Deep Dive
This blog digs into the vSphere inventory structure, and changes in vSphere 4 from VI. It explains the difference between ESX and vCenter inventory tree, why the inventory path you see from vSphere Client doesn’t work with API. Much of the content is adapted from my book VMware VI and vSphere SDK by Prentice Hall.
Inventory vs. Inheritance hierarchy
My previous blog introduced the object model of the vSphere API. The UML diagram there shows how different managed object types are structured in the inheritance hierarchy.
The inventory hierarchy is quite different. It shows how different managed object instances are associated. With this understood, you can easily navigate among different managed objects in inventory tree of both ESX and vCenter. It’s critical for programming vSphere API because navigating the inventory is the primary way to get hold of managed objects.
