This change is due to a revision of the underlying IEEE 1680 standard. EPEAT originally contained a ‘grace period’ that allowed previously listed products to remain on [...] OK – before it was space and utilisation that were the main costs and now it is energy – hardware efficiency is costing less but running it is going up plus we are all more dependent on business applications and using more energy to consume them. This is the current leitmotif for data centre management. But we [...] http://www.thegreengrid.org/academy.aspx. A free 'online learning solution' (surely there is a more efficient use of language than that!) on running an efficient data centre. The Green grid provides material for those interested in managing for efficiency. A number of organisations are active in this space – A sign that users want tools for measurement of data center metrics to justify efficiency investments.
