Introduction
Data centre Costs by Amazon.com
“Data centre expenses related cost of operation the servers becomes the 57% of total budget while energy-
related costs amount to 31%.”

Current State
Research community propose solutions for optimize each part of chain.
Current State
How DC can cut energy consumptions? • Energy-efficient opportunities for power consumption:
– Energy-efficient hardware
– Power minimization in Cluster & Networks
– Distributed Energy-Efficient Schedulers (DEES)
• Cooling consumptions can be cut by:
– Better air management
– Move to liquid cooling
– Use of free cooling (Green)!
Current State
Energy-efficient hardware • Processors Dynamic Speed & Voltage Scaling:
– SpeedStep (Intel)
– PowerNow (AMD)
– Cool’nQuiet (Dynamic fan speed)
• Advanced Configuration and Power Interface (ACPI)
• Other efficient emerging solutions:
– Solid State Disks
– Hibernation of hardware components
Current State
Power minimization on Clusters & Networks
“Components such as disks, memory or network devices also use energy when server is idle, still
using up to 60% of its peak power.”
How can be mitigated?
“According to some estimates, Internet may consume more than 860 TWh annually.”
Current State
Power minimization on Clusters & Networks
• Clusters
– Develop energy & economic criteria to dispatch jobs.
– Set part of servers down or to a low-power state.
– Use dynamic provisioning algorithms to obtain the minimum number of servers required respecting SLAs.
• Networks (seriously considered since recently)
– Energy-saving routing protocols for wireless networks.
– Research on topology control (real-time network graph modification).
– On-going development of new energy-efficient Ethernet standard (IEEE 802.3az).

Efficient Cloud Computing
Energy-aware Clouds
• Currently based on:
– Virtualization
– Consolidation
– Improvement on Cooling
– Energy-awared software: Cloud applications, Cloud programming models, etc…
Efficient Cloud Computing
Virtualization
• Allows partition computational resources and share the hardware:
– Many services often needs only small fraction of computational resource.
– Low server utilization consumes non-less than 60% of peak power.
– This services can be virtualized running on a virtual machine.
– Virtual machines can be: created, terminated, cloned or moved from host to host.
Efficient Cloud Computing
Consolidation techniques
• Resource optimization:
– Many virtual machines can run on a single hardware unit (consolidation).
– Live-Migration: VM host-to-host migration while running in nanoseconds.
– Reduction on cooling due distributing properly the VMs over physical resources avoiding thermal hotspots.
Efficient Cloud Computing
Consolidation techniques
Efficient Cloud Computing
Cooling Improvements
• Thermal considerations:
– Of data centre interior structure (ceiling, walls, floor, …)
– For consolidation and virtualization purposes.
– For interference effects on neighbouring computing nodes.
– For correlate the temperature rise, load and power consumption.
Conclusions
The IT business future is going to Energy-awared Data centers and Green Computing.
Nowadays, one can leverage a lot of available energy-awared technologies and techniques at different levels.
Researchers comunity is currently starting to tackle energy-efficiency problems.
Savings on Green House Gas and CO2 emissions!!!
