So, most people know that I work on some pretty big computers for a living. What’s really strange is how fragile those computes can be some times.

Here is the scenario. I’m called into work on a Sunday afternoon because our production cluster is having issues. Jobs will not run, everything is at a stand still. I come in and poke around a while and I finally find the culprit. A $1 fan on a 10Gigabit Ethernet card has failed, causing the Ethernet card to shut itself off to prevent itself from melting. The loss of the Ethernet card means that one of my management DNS servers has gone down. Because the DNS service is down the compute nodes have a time out before switching to the secondary. That time out period is enough to mean nothing runs. And I do mean nothing. 350+ compute nodes all making heat and keeping floor tiles down. All because of one little fan in just the right spot.

Here you can see the card the fan was on.

As part of todays exploration of Albuquerque New Mexico, Justin and I checked out the Petroglyph National Monument. The fact that you can wander among the rocks (on paths) and see/find all these different petroglyphs. It’s a pretty neat experience. I’ll let a few of the pictures I took speak for me.

Here’s a picture showing how close you actually are to the carvings/petroglyphs.

I’ve spent the last two days running around Albuquerque with Justin, a friend and co-worker. Today we decided to ride the tram up to the top of Sandia Peak . It’s the longest tram in the world. You end up going over 1000ft above the canyon below. The views of Albuquerque are amazing to say the least. However, be warned, it can be a bit scary on the ride up. Nothing like swaying from a wire a thousand feet above the ground.

Here I am at 10,378 feet above sea level looking down over the City of Albuquerque.

Here is what it looks like down onto the flatlands below. It was a bit hazy and overcast, but wow, what a view.

I took this picture on the way back down. It’s pretty country.
