On the other hand there is differing perception in the manufacturers and the users in the heat density reduction parameters, which need rationalization. Thermal management also needs to be included while designing devices and the issue is likely to become more complex over the years. Reduction of power is also related to power aware computing, which is designing software and hardware to ensure optimum management of power.
The growth of information technology has spawned a vast industry based around computers and information science. The impetus to economies and employment provided by computing ignores the silent yet alarming environmental hazard posed by systems compressed in small spaces requiring enormous amounts of power and generating large quantities of heat. Heat generated by computers is easily calculable, but one seldom takes into account the heat of hundreds of humans working in small spaces. There is increased awareness of environmental hazards of power and heat in computing, which are being addressed by the industry and academicians. The main issues to be considered are the nature and magnitude of the threat and measures that can be taken to minimize or overcome these. This is being carried out by a study of two prominent trends in computing environment, heat density and power aware computing.
In this section we will examine the trends in power consumption and resulting heat dissipation in computers and data processing as well as storage systems and central office type telecommunications equipment. A White Paper, “Heat Density Trends in data Processing, Computer Systems and Telecommunications Equipment” is the main source of the study. (Uptime Institute: 2000). A number of other papers and presentations have also been considered to validate the trends in the Uptime Institute paper.
There is a general feeling of smugness in the computing world generated by the
