The Dirty Secrets of Server Power

Power efficiency remains a top decision point for many customers looking to modernize their data center. Customers searching for an accurate way to compare server power among vendors are often directed to use power calculators without taking into account the many factors that drive power utilization. This notion preys on the simplistic nature of the power beast – lower number is better… but are we missing the (power) bus entirely?

The dirty little secret is that there is no industry standard for power calculators, and vendors can essentially publish a calculator around whatever workload they like (or no actual workload at all). Read More »

What if I shaded it with a piece of cardboard?  How fast would the spindle turn if I put the radiometer fully in the light? Read More »

What comes to mind when you think about the color blue? Whenever I think about the color blue in nature, I’m transported to the clear blue skies and turquoise ocean waves of Hawaii. For many people, the color blue has a restorative quality: It’s invigorating and puts us back in control of priorities. My affinity for “all things blue,” is why I was attracted to this story about Cisco customer, BlueWave Computing, LLC., a cloud services provider based in Atlanta, Georgia. BlueWave’s existing server and storage infrastructure had reached its limits and was creating performance and reliability issues. That’s when BlueWave decided it was time for a change. They worked with Cisco to reinvigorate their data center, making it ready for next generation of cloud services, and clearing the way for ”nothing but blue skies ahead.”
