The target markets Ken Baker, HP Data Center Infrastructure Technologist, says, ―Existing self-contained rack enclosures, including the HP Modular Cooling System, work well for high-density racks with heat loads above 10kW. But the majority of the market consists of small and medium data centers with partially full racks and heat loads ranging from 3kW to 7kW per rack.‖ These data centers typically have power and cooling constraints rather than space constraints. Ken says, ―They want their facility deficiencies to stop limiting their IT deployment strategies, so they need to use all of their existing rack space and available floor space without increasing their facility's heat load.‖ The modular data center Eaton and we are working on a fully enclosed IT rack system, or modular data center (MDC). The MDC will provide 100kW of power and cooling capacity using high voltage AC (400v-480v) and chilled water as the primary inputs. The MDC can also use intermittent power from renewable energy sources. The MDC powers the IT equipment using distributed high-voltage DC power for maximum efficiency. The MDC's management system aggressively controls energy use to optimize internal resources based on electrical grid demand, peakdemand usage times, and the availability and strength of wind and solar power. The MDC includes management controls that actively optimize the internal environment for dynamic IT loads, and interface with facility management systems to provide an end-to-end view of the power and cooling chain. The MDC supports four, six, or eight 42U IT racks. That equates to a cooling capacity of 25kW/rack for four racks or 12.5kW/rack for eight racks. This requires an innovative cooling system that can fit in a single bay at the enclosure's center. Figure 1-1 shows an MDC with four bays, two on each side of the cooling system bay. One of our main goals is to design the MDC so that two people can install it in two to three days with the aid of an electrician and plumber to connect the power and cooling water inputs. The enclosure may be up to 7300mm (24 ft.) wide including eight IT racks and the cooling system bay. The MDC will be approximately 1800mm (6 ft.) deep, with up to 600mm for cold air circulation.
