tell me/us if you consider noise reduction to be "green"
Absolutely not. The environmental message behind "green" is very widely accepted to ultimately boil down to sustainability and greenhouse gas emissions - whether it be through elimination of materials like mercury or lead from manufacturing processes, to more efficient products that consume less energy. Something that has less material impact on the environment.
Calling noise pollution reduction "green"? Total "greenwash"! Going to market with that claim would damage a brand in my opinion. How does a quieter rack help the environment? Does it keep equipment cooler, reducing electricity consumption? Unlikely. My guess is that the product in question increases cooling requirements of the components inside!
Most companies are looking for efficiencies that impact the bottom line. Being able to tout themselves as "green" is a marketing spin benefit when they move from 100+ physical servers to just 4 or 5 running virtualisation - the real win for the company is cost savings achieved through less energy requirements (lower energy consumption, and lower air conditioning requirements), less hardware maintenance (with possibly lower staff costs) and cheaper hardware support contracts.
I am glad you brought this up...because we use high volume fans (76 CFM) that use about 11 watts, we may be helping reduce energy and noise of course... because the fans are only 30 db even when moving a ton of air.
You can imagine when a server normally sits out in the open, it draws air in from its surroundings and out puts the hot air fairly close to where it intakes air from. With our XRackPro2, air is pulled in from the bottom front and hot expelled air from the equipment inside is sucked out the rear near the top. This distance between cool intake and hot exhaust is much bigger with the XRackPro2...so less chance for re-circulating hot air back into the cabinet.
Also, with 76 CFM of air per fan passing through the cabinet constantly, there may be a wind chill effect..I say "may" because we have not officially tested for it yet. Worst case, that much air flow moves the warmer air away from the equipment faster and further. Some customers do report their server, RAID, switch, etc. equipment fans spin slower because their equipment is running cooler...again, it is untested...but we know people's equipment is not overheating...hmmm
...and by the way, we do all that while filtering the incoming air...which lowers maintenance cost and down time.
So, thank you for bringing this up and we will have to investigate the power usage trade-offs between the XRackPro2 and the equipment inside.
