Abstract: A data center includes two or more rack computing systems and an air handling system. The rack computing systems may each include racks and computing devices mounted in the rack. The air handling system includes one or more air moving devices external to the one or more racks. The air moving devices create a negative pressure relative to ambient air at air inlets to the racks to draw air from the inlets and through computing devices in the racks.

Abstract: A system for managing air flow computing devices in a rack includes a stall and filler elements. The stall includes a stall top panel and two side panels spaced apart from one another. The stall accommodates a rack computing system. The filler elements fill gaps between the computing devices of the rack computing systems and the panels of the stalls. An air moving system moves air from the cold aisle through cold-aisle facing air inlets of the computing devices. The filler elements inhibit air moving toward the cold aisle-facing inlets from leaking through gaps between the computing devices of the rack computing systems and the stall panels such that the filler elements inhibit air moving toward inlets in the computing devices from leaking through the gaps between the computing devices in the rack and the stall panels.

Abstract: A data center includes two or more rack computing systems, a free cooling system, and an electrical power system. The free air cooling system includes air moving devices external to the rack computing systems. The electrical power system includes switchgear and one or more power panels. The switchgear receives power from a utility power feed. The power panels receive power from the switchgear. The power panels supply electrical power to the computing devices.

Abstract: A method of operating a data center includes providing a first operating environment in a first portion of the data center and providing a second operating environment in a second portion of the data center. The first operating environment meets a first set of infrastructure specifications. The second operating environment meets a second set of infrastructure specifications. At least some of the infrastructure specifications of the second set of infrastructure specifications are less stringent than corresponding infrastructure specifications of the first set of one or more infrastructure specification.
