Article on Air-Side Economizers

Here is a great article on air-side economizers: http://findarticles.com/p/articles/mi_m5PRB/is_12_49/ai_n25125555/?tag=content;col1

Not many data centers in the country do you get the opportunity to see wildlife on a daily basis. This is often our view as we go about our daily business and this was the case this afternoon on a beautiful Colorado day. No asphalt, no concrete, no cars, no freeway,etc..

Won't you come join us?

p.s. no feeding the deer..

Cluster Update

We've finished up the build out of our heat containment wall which currently houses a customer's Dell 128 node cluster with master nodes and NAS storage. The room is currently cooled by 2ea. 3-ton Sun A/C units with air-side economizers. The 2nd unit is actually a backup so the entire room is currently being cooled by one 3-ton unit. It's been using 100% outside air with no compressor except for today when the temperature reached near 75 degrees.


Here are some photos. Notice the 4 blue racks on the left. These are for future customers and the wall to the left of those cabinets was built to be easily removed so racks will fill the entire row except for the doors.




The neat thing is if you go to http://dell.com/calc and put in 3-3/4 racks of PowerEdge 1950 III 3.5" drives, you will see it requires 14.2 tons of cooling. We're doing it with 3 tons (a 3 ton as a backup) saving a TON on A/C power. It's time to shake up the industry a bit and think outside of the box. I invite other data center managers both in the private and public sector to schedule a visit, we would love to show you the details.

I'm posting our initial Visio diagram of our final plan for this room.

Sun using economizers..

Down the street from us, it looks like they realized the cost savings as we have.

Next project...

We've been chosen by Tierra Geophysical to provide a home to their new Dell cluster. This cluster contains 128 "nodes" which are actually 1U Dell servers. To cool this extreme amount of heat, we've decided to think outside the box much like we did with our Trane economizer.

The plan is to "contain" the over 38,000watts of heat being produced by all of these 1U servers and exhaust it outside. You might ask, well, great idea...but where will you get the make up air to supply to the servers..???? We thought you might ask that..

Below is the initial design of this room. As you can see, 3 existing A/C units will supply the air flow needed for this cluster. These units were already equipped with air-side economizers which will use outside air 100% of the year. The reason for this is because it will be easier to cool outside air than very hot server air which is usually greater than 105 degrees.

Since our new customer is going to be paying their own power bills, we estimate that using a 100% economizer approach will save them $900+ a month.




Once the project is completed, we'll post pictures of the results.

December Results

We received December's bill and we've reduced our energy consumption down to 3920 KWH used from 6240 saving us a total of $496.77. Our next project is to duct the hot server air into our offices to eliminate the need for office heating. This is probably 20% of our current bill which is included on this bill. So, even though we've saved $496.77, it would actually be more than that if we didn't need to heat our office...
