So the past two days we were fighting with what to do about sudden rising temperatures in our server closet. This sort of thing happens every year around this time, as the regular lab air conditioner which "assists" our closet by keeping things extra cool in the sunny summer obviously doesn't do the same as we enter foggy fall. We also have some nagging tiny imperceptible coolant leak so we need to recharge that every so often. In any case, the systems were getting hotter, so we ultimately had to shut everything down (the idle disks and CPUs generate far less heat). This morning the right people were called to inspect the situation. Turns out our air conditioner was more or less okay (we'll add more coolant soon) but the lab air conditioning system did konk out over the weekend. Apparently the lack of assist - even the slight amount during this wet weekend - pushed us over the edge. Before we figured this all out we had a meeting and planned on several courses of action to remove as many aging, less efficient systems from the closet. I planned to get three systems out by the end of the day (download server, and the two public web servers) but due to annoying little nested problems I've been only able to get the download functionality out of the closet so far. Downloads are currently being served from host vader. I'll shut off penguin shortly - it's not so much a crisis now but we've been meaning to get off those Sun 220s for years. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Cut a couple of holes in the door to the server room - put a box fan in one to push the heat from the server room into the lab (assuming the lab has a thermostat). BOINC WIKI |

You guys are doing a great job, thanks maybe you guys should add an air-co upgrade inthe next fund-raise ;) |
