This was a good move but many of us felt it was late and not nearly a big enough increment.  Earlier this month, ASHRAE announced they are again planning to take action and raise the recommended limit further but haven’t yet announced by how much (ASHRAE: Data Centers Can be Even Warmer).    Many datacenters are operating reliably well in excess even the newest ASHRAE recommended temp of 81F. For example, back in 2009 Microsoft announced they were operating ... (Read Full Article)
