Reminds me of when I was a kid and drove ignoring my temperature gauge - only to end up roadside with a warped head on my student beater! <br /><br />Take that concept to the data center - and a lot of folks are just driving blind. Everyone is used to server failure, running out of power, cranking the cooling - but these are things that we should not be used to but rather be trying to optimize so we don't have to deal with them! There is an element of human behavior needed here. 2010 should be about an attitude change to start questioning the things we do in the data center. Rather than taking energy-cost measures - we switch to energy -efficient approaches.<br /><br />On the topic of measurement and "how do you start this change" wireless real-time monitoring devices are a simple, low cost way to get started and fill in the measurement gaps in any enterprise environment. Look for open product solutions that allow the integration of your existing assets and any data that you might be already collecting. It's as much a "data collection" issues as it is "data integration"<br /><br />On the wireless/energy management vendor side, another company (and one that I work with) is Arch Rock Corporation. Cool people, cool products. You can check them out at http://www.archrock.com. All the vendor sites have great reading material - so use them as educational resources to help you get up to speed on the wonderful world of PUE.<br /><br />I hope that enterprises make PUE a mandatory metric for 2010. It's time. <br /><br />-Tom<br />www.puedcie.com<br />@pue_dcieAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4965846665905338838.post-87063860095466614962010-01-13T09:55:58.110-05:002010-01-13T09:55:58.110-05:00Brent,
You would have to look at your particular ...Brent, <br />You would have to look at your particular layout to find the simplest measurement points. You could use your measurements from the full building depending on what else is in the building. If the data center is a small portion of the building then the results will be less than useful though. Measuring the power as far up stream as possible while still being mostly limited to Data center use is the most accurate. Getting above the transformer that leads to the data center UPS, or at the generator transfer switch. Try to include chillers, pumps (if chilled water), and any other possible support equipment, such as lights. <br />For the computer equipment load measurement, you can most easily take this on the output side of the UPS units, but for more accuracy (and more difficulty) measure at each rack PDU, and for most accuracy (and most difficulty) measure at each computer. <br />There are some non-invasive devices that can be used to measure power very accurately such as :<br />http://www.smart-works.com/smart-pdu/<br />http://www.synapsense.com/go/index.cfm/data-center-solution/powerimaging/<br />I can give you links to a few others if you like, but these would be for a real time constant measurement installation. If you are looking for a one time or quarterly measurement find the points that are the simplest that include the most possible equipment or get a consultant that will bring in the equipment needed and give full evaluation reports. <br />Send me a note if you want more direct assistance.<br />RichardButchDealhttps://www.blogger.com/profile/03667968800541001018noreply@blogger.comtag:blogger.com,1999:blog-4965846665905338838.post-32921684081118464592010-01-13T09:01:25.015-05:002010-01-13T09:01:25.015-05:00Richard,
I hear what you are saying, but what'...Richard,<br /><br />I hear what you are saying, but what's your recommendation for those of us who don't have a BMS to give us readings for the various mechanical & electrical systems. We use both AC & DC powered IT eqiupment, so I can take readings from both systems and the full power draw for the building.<br /><br />Thanks<br />BrentAnonymoushttps://www.blogger.com/profile/13446122808710825834noreply@blogger.com
