Data centers today lack a formal system for classifying infrastructure management tools. As a result, confusion exists regarding which management systems are necessary and which are optional for secure and
efficient data center operation. This paper divides the realm of data center management tools into four distinct subsets and compares the primary and secondary functions of key subsystems within these subsets. With a classification system in place, data center professionals can begin to determine which physical infrastructure management tools they need – and don’t need – to operate their data centers.
