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.
