Lowering Energy Costs in the Low End datacenter
I'm curious to know what my fellow providers do to keep costs down in their fellow datacenters.
Hopefully not that. But what do you spend money on to save money?
We've only been using LED light. All lighting shuts off automatically when leaving, CRAC tune-ups.
Extracting the hottest air to be replaced with external air in the cold months.
Using Datacenter Air to heat the rest of the building in the winter.
All un-rented stock kept offline. Employee areas only conditioned/ventilated while occupied.
packing the space between racks and underneath with foam to prevent air seepage from cold-to-hot aisles.
Do any of you preload config/modules to reduce power usage on your individual nodes? I've had great success with powertop from Intel at reducing power usage of laptops. It tackles hundreds of little things like shutting off unused busses and controllers, reducing cpu wakeups, more efficient IO scheduling, thermal fan throttling. Across a whole datacenter that could make a big difference.
What kinds of Cooling are the cheapest to run in your Low End environment and why?
