Data Center cooling strategy is essential. For this reason, understanding the role the server rack plays is very important. Current denser technology servers such as Blade servers generate immense heat. The type of rack you deploy will depend on the cooling methods used in your environment. The baseline kilo watt of heat output per rack varies widely depending on the type and density of equipment. This could be anywhere from 3 kilo watts to 15 kilo watts (3kW-15kW) or more per rack.
