[60] [61] Single and dual/two phase immersion/open tub cooling and single and dual phase direct-to-chip cooling [62] as well as immersion cooling confined to individual server blades [63] [64] have also been proposed for use in data centers. [65] [66] In-row cooling, [67] [68] [69] rack cooling, [70] [71] rear door heat exchangers, [72] racktop ...
The cooling of data centers is the second largest power consumer after servers. The cooling energy varies from 10% of the total energy consumption in the most efficient data centers and goes up to 45% in standard air-cooled data centers.
Open-bath immersion cooling is a data center cooling technique that implies fully submerging IT equipment in dielectric liquid. The "open" aspect does not refer to an open or sealed system, but refers to the "open" liquid-air interface and thus surface tension between the liquid and the air is a distinctive element. [30]
Close Coupled Cooling is a last generation cooling system particularly used in data centers. The goal of close coupled cooling is to bring heat transfer closest to its source: the equipment rack. By moving the air conditioner closer to the equipment rack a more precise delivery of inlet air and a more immediate capture of exhaust air is ensured.
Google data centers are the large data center facilities Google uses to provide their services, which combine large drives, computer nodes organized in aisles of racks, internal and external networking, environmental controls (mainly cooling and humidification control), and operations software (especially as concerns load balancing and fault tolerance).
They typically use standardized components, which make them easily added, integrated or retrofitted into existing data centers, and cheaper and easier to build. [4] In a colocation environment, the data center module is a data center within a data center, with its own steel walls and security protocol, and its own cooling and power infrastructure.
A colder climate results in a lesser need for a massive cooling system. Cooling systems account for roughly 30 percent of consumed energy in a facility, while the data center equipment accounts for nearly 50 percent. [9] Due to this, the Miami data center may have a final PUE of 1.8 and the data center in Alaska may have a ratio of 1.7, but the ...
The HP Performance Optimized Datacenter (POD) is a range of three modular data centers manufactured by HP.. Housed in purpose-built modules of standard shipping container form-factor of either 20 feet or 40 feet in length the data centers are shipped preconfigured with racks, cabling and equipment for power and cooling.
