But, last week at the monthly All-Staff meeting, IMA employees were treated to a sneak peek of a monitoring project that the MIS department has in the works. It’s similar to what I wrote about in an earlier post, but on a bigger scale (by the way, that Eco-button went glitchy on me). In the IMA machine room, we have rack-mounted servers that host a variety of applications used by staff at the museum. There’s also a decent 16 terabytes (1TB = 1024GB) of disk storage in there.

While perhaps not as impressive as the grocery store-size aisles of a supercomputer like the Earth Simulator (which was recently rated as the world’s most computationally-effficient supercomputer), our servers do suck their share of power. The two most significant energy inputs to this system are the cooling unit and the UPS (uninterruptible power supply).

We have a system that monitors the power used by both the UPS and the cooling unit, and we’ve been performing measurements since February. Recently, we added a routine that calculates daily consumption for the current month. The plan is to put this information on the IMA Dashboard, and we’re using this opportunity to try out Google Charts.

One of the key survival tools for anyone on the quest for sustainability is measurement. From the data we have here, it appears that we have a baseline of about 1300kWh per day. Knowing this, when we swap out hardware in the future we will be able to determine how much of an improvement we actually make, as opposed to relying on theoretical figures.

Of course, we’d like to be confident that our measurements are correct. In order to do this, we’re using Kill-A-Watt devices to measure power input on individual components in the rack. If the measurements are correct, the total power calculated from sampling individual units should be approximately equal to the power measured by the monitoring system. If not, we’ll have some investigating to do.

Hopefully, our measurements will validate and we’ll soon have live data up on the Dashboard. Until then, check out some other fancy energy usage dashboards.

You can find a lot more graphs from the survey results in the rest of this post, but I thought it would be interested to just pull out a few interesting stats for you up front.

Stats Quick-Hit:

  • 480 People took the survey between 12/22/2009 and 2/9/2009 (our web traffic during that time included 113,000 unique visitors and 450,000 pages served)
  • Almost 90% of people who took the survey were satisfied or very satisfied with their experience on imamuseum.org
  • The average visitor is Female (67%) and between 25-34 year old.
  • More than 55% of website visitors use Facebook! Guess keeping the IMA’s facebook page flush with content is a good idea!
  • Sadly 51% of survey-takers Never Comment on Blogs (c’mon… poke us a little, we don’t bite!)
  • Survey-takers were overwhelmingly Caucasian. Our real attendance through the doors of the museum is different than this, so it seems like we need to do a better job of reaching some different audiences.

We’ll be contacting the lucky winner of the iPod touch this week and sending out the love to them!  Thanks to everyone for helping us with the survey!  We’ll be back in touch as we put together a new set of user personas to use for some upcoming web work.

In the mean time, enjoy sifting through our data for us.  If you see anything interesting here, be sure to be one of those 49% who do comment on blogs, and Let Us Know!  We’re happy to answer any questions you ask!
