Look energy costs are going to rise and rise quickly so energy efficiency for data centers is crucial.
So now they have teams of people at companies running around to figure out that energy savings equals dollars.
Along with driving up complexity, extra hardware increases energy consumption and lowers the total gains.
A software alternative can be Holistic energy management
Energy management software can play a key role in curbing energy costs by programmatically collecting and aggregating the real-time temperature and power consumption behaviors of data center servers.
Since servers consume most of the energy in the data center, and use 60 percent of their maximum power even while idle, gaining visibility of the server operating characteristics is an important step for improving overall efficiency in the data center. Modern servers provide real-time status information, and this data can be collected over existing infrastructure by agentless, centralized energy monitoring software.
