From time to time one of my EMC blogging colleagues will spend a bit of electronic ink on matters related to energy. I find it encouraging when they do, since it has always been my objective to have the topic become woven into our discussion - not stand alone.
On the other hand, they don't typically scoop me as Mark "Storagezilla" Twomey did yesterday.
- No offense taken Mark. Always happy for help toward the cause -
For nearly two years, EMC has had a Power Calculator available to EMC field staff and partners to assist in understanding specifics about power and cooling for different storage system configurations.
It's a cool tool. (Get the puns if you can.) Makes it simple to calculate annual operational costs, weight, floor space, sound levels, and of course, power and cooling requirements.
It has been a terrific resource to help customers with guidance in comparisons of multiple configurations and sites, to help comparing current and previous hardware generations or in making storage tiering trade-offs among cost, performance, capacity and energy consumption.
So, useful as it has been to our own staff and partners, we wanted to make it available to our customers too.
If you are an EMC customer, go have a look on Powerlink and let us know what you think.
This is where I would have said "Ta Da!" but Mark beat me to it.
Thanks Dave. Independent coroboration is always valued.
No need to apologize Mark. You prodded me to write a post that was overdue.

Hi Dick...I said this on Mark's blog and I'll repeat it here. I and my Wikibon colleague David Floyer had an opportunity to do an independent validation (measured) of EMC's Power Calculator. The tool is incredibly accurate. We validated about a hundred random data points in the tool across multiple workloads and every single one was within +/- 3%. (I said +/- 1% on Mark's blog but I went back and checked and there were a couple that were like 2.8% off-- please don't shoot me!).
As a point of reference, power measurements are notoriously variable and anything within +/- 10% is good. 3% is amazing.

Sorry Dick! :-)
