I need a server to work during a hurricane. I need it to produce very little heat and consume very little energy. It also needs to be water resistant. It must be able to run from generator power and provide weather and safety information to users over a wireless access point. Living in south Florida, we get hurricanes all the time. We also have a huge risk of flooding from those hurricanes. Being able to deploy quick and reliable servers is key to storm recovery.
How much direct water contact occurs?
It appears that we need to talk to our engineers about true waterproof casing for the unit. It can handle humidity quite fine, but not actual submersion in water.
This one definitely raises the bar pretty high. I'm just glad you didn't include surviving to be hurled up and blown away a few miles in your requirements...
