We describe a new approach to minimize the power used by servers and computer room air conditioners (CRACs) in data centers by controlling them in an integrated way. This approach consists of air conditioning control using a new thermal model to keep inlet temperatures of servers under certain limits and allocation control of virtual machines (VMs) for(More)
