Sun Metric Sizes Up Data Center Efficiency

The Sun-developed Space, Watts and Performance metric is a way of evaluating a data centers efficiency. The key differentiator from other measuring tools is the introduction of data center real estate as part of the equation, according to officials of the Santa Clara, Calif., company.
Power efficiency was a key driver behind the development of the UltraSPARC T1, formerly code-named Niagara. The chip offers up to eight cores, each of which can process as many as four instruction threads simultaneously, but it offers a power envelope of about 70 watts, less than that of processors from such competitors as Advanced Micro Devices Inc. and Intel Corp. The first systems running the UltraSPARC T1, the Sun Fire T1000 and T2000, were unveiled last month amid statements from Sun executives regarding the need for technology that not only helps businesses reduce costs but also does less harm to the environment.
