The modern data center is an increasingly complex environment. Knowing what assets are on hand and where they are located is vital. Periodic inventories and fixed asset audits are a mandatory and laborious element for any IT department. In large data centers, these time-consuming endeavors are both rigorous and agonizing. Asset inventories and audits need to be complete and accurate. For those with a hundred or more racks full of critical corporate servers and related computers, storage devices, network hardware and test equipment, its no longer possible to maintain an up-to-date inventory with manual processes. Not with a pencil and paper. Not with bar codes. Not with passive RFID (Radio Frequency Identification).
