If you transfer result files from your Solid during a run, you might be overheating your instrument. Meaning that processes impacted by temps being out of range could suffer.
Due to climate control issues in our lab, we keep a thermometer/hygrometer probe inside our Solid, just in front of the chiller. This morning our lab was unseasonably warm, but still within the temperature specifications of the Solid (20 - 24 oC). However, inside the instrument the temps were quite a bit higher -- approaching 28 oC!
I quickly turned on our extra chiller and some of our fans. This helped, but what was the source of this heat? Turns out we were copying about 130 gigabytes of data off the head node to our downstream processing cluster over a 1 gigabit/second network connection.
Unlike the larger RAID array blade, (MD1000), the head node is high in the rack, nearer to the instrument. Its drives apparently produce enough heat that either it conducts through the instrument to the "wet" part of the instrument above, or the exhaust from the head node is getting sucked into the instrument though the (vortex?) fan of the reagent chiller block.
Either way, something you might want to consider if you do image processing on your instrument cluster then transfer the .csfasta and .qual files off the instrument. You might want to limit your transfer rates if the instrument is still running!
