Running a data center takes a lot of work, and even making sure the ambient temperature for hundreds of boxes is in the proper range is an arduous task. When faced with the prospect of installing hundreds of temperature sensors in an EMC data center, [Vivek] had a better idea: put just a few sensors on a robot and drive around the racks. With the right software, it’s a breeze to automate the process and build a near real-time temperature monitoring solution for a huge data center.
The data center robot is based on a iRobot Create, basically a Roomba without a vacuum. Attached to the robot is a netbook, Arduino, and a PVC mast housing three temperature sensors and a USB webcam.
Using the floor of the data center for navigation, the robot canvasses the racks sending temperature data back to a server via WiFi. From there, the temperatures can be graphed to make sure the racks aren’t too hot or too cold.
You can check out a video of the robot in action after the break.

[DocDawning] had a nice home network up and running, but the messy pit housing the hardware made him avoid that part of the house. In an effort to cut down on noise, and clean up the clutter, he built himself a very nice data center inside a small closet.
One of the biggest changes in the setup provides adequate cooling. He cut a vent hole into a wall shared between the closet and a hallway. This was just the right size for a few large cooling fans which suck air into the enclosed space. But cool-air intake must be accompanied by hot-air outflow so he added an exhaust vent in the ceiling. This also received a trio of big fans, and as you can see above, the integrated LEDs act as a light source for the server farm.
The final part of the plan involved machine-specific brackets mounted to the walls of the enclosure. These racks were built out of 1×1 white wood. They hold the hardware in place leaving plenty of room to run cables. The new setup even opened up enough wall space to mount power and networking hardware. Now everything has its place, and [DocDawning] can finally close the door on his noisy servers.
Remember Mauritius from High School geography? We didn’t either, but apparently it’s a small island nation east of the southern tip of Africa. It seems they are trying to develop an industry in eco-friendly data centers. The plan is to use a pipeline to gather cold water from the ocean, run it two miles to the island, and use it as inexpensive cooling. Because rooms packed with servers generate copious amounts of heat it’s easy to see how this can reduce the cost of maintaining a data center.
The thing that struck us here is, how eco-friendly is this? The article mentions that this technology is fairly mature and is already used in several places. With that in mind, isn’t this just another way to raise the temperature of the oceans, or does the environmental savings of not using electricity or gas to produce the cooling offset this?
