“Auditing what’s there and decomissioning the equipment that’s unused or consolidating it is a real quick win and can typically be done in a short amount of time,” Polastre says.

Take Credit For Energy Use

Joe Polastre — Fri, 17 Jun 2011 17:00:01 +0000

Dr. Joe Polastre, CTO of Sentilla, warns that data center managers need to be ready for regulation. “Today, carbon does not play an impact on the enterprise,” he says. Most countries are looking at either a flat tax or cap-and-trade system, Polastre points out. In either case, the cost impact on enterprises that run their own data centers is expected to be between 4% and 6% of its total electricity usage.

Tackling Old Problems with New Solutions at Uptime’s Symposium

Joe Polastre — Wed, 11 May 2011 19:00:45 +0000

“When does a CIO care about energy?” Joe Polastre, CTO of Sentilla asked me. “When he or she can’t deploy a new application. Why can a data center run at 8 percent of its capacity?” Polastre asked. In any other industry you’d lose your job in a heartbeat. Instead, IT is benchmarked with the wrong rulers: Polastre said that such low efficiencies are possibly only because the data center is measured only by tech metrics. A shift to using business metrics would put those efficiencies under the scrutiny that will drive change much more quickly.

IT Can Now What-If Virtualization, Cloud Saving

Joe Polastre — Wed, 02 Feb 2011 00:18:40 +0000

“We help organizations move from ‘IT as a cost center’ to ‘IT as a service,’” said Polastre. “We can now look at each individual service and say: ‘How can we provide that more efficiently,’ making good decisions about what to virtualize, when to virtualize, where to virtualize it, whether it should use cloud resources or equipment refresh or new data centers or refurbished old ones–all those kinds of decisions will now be easier to make.”

An Unexplored Frontier: Energy-Per-Click

Joe Polastre — Tue, 01 Feb 2011 08:01:01 +0000

Imagine if companies could track the energy usage of a single individual web user uploading video content to YouTube, or the amount of energy consumed by a lone click of a mouse to store photos in the cloud. It might sound like a pipe dream, but Sentilla CTO Joe Polastre thinks that eventually the rapidly growing industry around data center and IT energy efficiency could provide that kind of transparency.

Putting the Data Center Under the BI Microscope

Joe Polastre — Sun, 19 Dec 2010 22:17:22 +0000

“CIOs must be given the same level of visibility into the financial and environmental impacts of their IT services as they have in fields like market analysis and supply-chain management.”

Real Innovation is in the Applications

Joe Polastre — Thu, 09 Dec 2010 20:02:18 +0000

“If the data center’s sole purpose is to deliver services to its users or business, then why do we keep rehashing age-old common-sense cooling strategies? We should be talking about the applications, because that’s where real innovation and efficiency lies. Make the applications more efficient, and the rest of the infrastructure will reap the rewards.”

Is Cyber Monday Really Energy Efficient?

Joe Polastre — Wed, 24 Nov 2010 21:30:22 +0000

The top 40 retailers spend an estimated $110 million more on energy during a given year than they should in preparing for Cyber Monday. “The carbon impact of this power waste is approximately 727 million pounds of carbon dioxide. That’s more CO2 than emitted by all of the round trip flights each year between SFO and JFK,” says Joe Polastre, Sentilla’s CTO and co-founder.
