When you need to manage large numbers of devices, there is no avoiding centralized data management. In the simplest case, this can be a wiki, with one entry per system. This will include, for example, the date of purchase, the length of the warranty period or maintenance contract, any repairs that have already been made, and the rack number where the device is installed (finding the hardware in a larger data center can be time-consuming).
