Proper Planning = Proper Operation

摘要

Moore's Law states that at our rate of technological development in the semiconductor industry, the number of transistors doubles every year (now every 18 months). As the number of transistors increases, processing speeds go up, which results in greater heat loads in the same area. The result: Your computer rooms are getting smaller. The new rack and blade servers are much more efficient in terms of processing speeds and capacities. They take up less room, are easier to cable, and components can be changed out much easier than with older legacy systems. However, the heat load is going up in terms of square footage. Some racks can have up to 24 kW in a 7-square-foot area. This translates into almost 7 tons of cooling, or, put another way, 1 ton per square foot of equipment.
