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 »

Cisco’s server power engineering team recently compared the Cisco UCS 5108 Blade Server Chassis with B200 M3 blade servers against HP’s BladeSystem c7000 Enclosure and HP ProLiant BL460c Gen8 blade servers.
The results weren’t surprising internally, but they might surprise you. The main findings were:
- The Cisco UCS 5108 enclosure configured with Cisco UCS B200 M3 blades achieved a 6.3% higher performance-to-power ratio than the HP BladeSystem c7000 with HP ProLiant BL460c blades, using with similarly configured hardware, BIOS, and OS settings.
- At a 70% target load, the Cisco UCS blade solution consumed 6.5% less power than the HP ProLiant blade solution.
- At the maximum target load, the Cisco UCS blade solution consumed 192 watts (W), or 7.2% less power, than the equivalently configured HP BladeSystem solution.
- The Cisco UCS blade solution consumed 167 watts, or 17.4% less power, while idle than the equivalently configured HP BladeSystem solution: a difference equivalent to the power consumed by three idle HP ProLiant BL460c Gen8 blades.
- Including the power consumed by a pair of redundant Fabric Interconnects, the Cisco UCS blade solution consumes less power than an equivalent HP BladeSystem solution.
The complete results are posted on Cisoc.com (link to download the entire white paper) so that you can replicate the results independently.

When I was a kid, one of my neighbors had a solar radiometer. It’s a glass bulb about the size of a baseball, with diamond-shaped panels connected to a spindle. The panels, black on one side and silver on the other, would turn on the spindle when exposed to light.
I enjoyed experimenting with the gizmo, edging it in and out of the sunbeam that shone through a window and onto their kitchen table. How close to the light did the radiometer need to be for the panels to move? 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?

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.”
