DATACENTERS & CLOUDS


All the energy provided to a datacenter is used to storage (47%) Cooling (34%), Conversion 7%, Network (10%) and Lighting (2%).
We define the Power Usage Effectiveness (PUE) as the quotient between the total datacenter power and the power used for ICT. This value is usually equal to 2. The Data Center Infrastructure Efficiency (DCIE) is the inverse of the PUE.
The elasticity capacity provisioning consist on exploit traffic fluctuations to aggregate jobs on a subset of servers and turn off the idle ones. Then the idea is to adequate the capacity to the traffic demanded.
