Don't Let Ghost Servers Spook You, Identify and Eliminate Them With CPI's Power Solutions

October 31, 2016

Ghost Server BlogHere’s a way to save hundreds of thousands of dollars in energy consumption this Halloween: target those ghost servers creeping around your data center with Chatsworth Products’ (CPI) intelligent power solution: eConnect® Power Distribution Units (PDUs) and Power IQ® for eConnect.

Ghosts or “zombie” servers haunt even the most sophisticated organizations and are one of the largest consumers of energy within the data center environment. They are servers that are either not running any workloads or are underutilized, but still consume power.

A recent research co-authored by consultancy Anthesis Group and Stanford University found that 30 percent of servers in data centers are ghosts. According to the findings, there are about 10 million ghost servers worldwide, which translates to roughly $30 billion in data center capital sitting idle in the globe.

By eliminating ghost servers, IT managers not only reduce energy consumption and improve capacity, but also save thousands in incurring software licensing and hardware maintenance costs.

Specter Detectors: eConnect Monitored Pro and Switched Pro

In order to manage power consumption properly, measurement is key. Knowing baseline power consumption of servers during their normal compute operation when they are provisioned is a good starting point.

Actual power consumption of a server can be determined by utilizing intelligent PDUs with metering at the outlet level, such as eConnect Monitored Pro and Switched Pro PDUs from CPI.

CPI’s Monitored and Switched Pro eConnect provide reliable power distribution for evolving data centers, while providing per-outlet monitoring of voltage, current, power (kW) and energy (kilowatt-hour) levels with a ±1% metering accuracy for each piece of equipment. eConnect Switched Pro PDUs also provide remote control (on/off/cycle) of each outlet.

Ghost Buster: Power IQ for eConnect

Using a power management software application such as CPI's Power IQ for eConnect allows IT managers to track the historical consumption reports of the servers so that they can compare them against the baseline consumption. These reports can be scheduled at regular intervals or generated on demand. By monitoring low power consumption against a baseline you can determine potential ghost server candidates. A utilization study of all the candidates would further determine the ones that should be decommissioned.

 Don’t Be Afraid of no Ghosts

“Removing idle servers would result in gigawatt-scale reductions in global IT load, the displaced power use from which could then support new IT loads that actually deliver business value. That’s a result that everyone should cheer,” concludes Jonathan Koomey, PhD, one of the authors of the server utilization research.

On that note, ongoing measurement and management of the IT server infrastructure are key factors to achieving IT efficiency.

CPI’s power management solutions will protect your technology investment, while allowing for full use of rack space, redundancy and future growth. Learn more about CPI’s approach to power management.
