One of the low hanging fruit in our DC design was going for cold aisle containment. This simply involves sealing the cold aisle (roof, doors and blanking panels) … this stops air mixing and avoids the warm air from the servers heating the cold air you have just spent a fortune cooling.
Source super efficient UPS’ … these UPS’ operate at up to 98.4% efficiency. That is a massive improvement over traditional UPS’ which were typically only around 75% efficient.
Typical data centers operate at 19-21C (66.2-69.8F) but in conversations I have had in recent months with HP, Sun, Dell and IBM all have said their equipment will operate no problem in data centers at temperatures of 25C (77F)…
