It’s just coming up on 04:00 in the morning here at Roller Network on a Saturday (we’re doing some off-hour line card insertions), and even though it’s summer in our part of the world the high desert climate of Reno still lends itself to suitable economizer cooling mode on our primary facility cooling systems every night almost year-round. Right now it’s about 60F (15C) outside and we’re using that air for cooling rather than run the compressors.
That’s pretty good considering we’re not way up in Alaska, and much better than other competing desert locations at night like Las Vegas (78F/25C) or Phoenix (88F/31C) where the night temperatures are much higher than ours in Reno.
