Power & Non-Power aware

Non-Power aware:

Generate random workloads with randomized constants VMs, Hosts etc., could be achieved with the class non-power aware class of examples.power.random within org.cloudbus.cloudsim. The corresponding class is NonPowerAware. The sequence of classes to be called are:

• RandomConstants
• RandomHelper
• RandomRunner
  • Actual implementation is called from here

Power Aware Planetlab:

Dataset of CPU utilization traces collected from the Planetlab in 10 days in March 2011. Host and VM information collected during these days. 288 entries in a dataset, every 5 mins interval data is logged for 24 hours. ie., 146-179-suf..net_xx (node, VM) as nomenclature for each file

Power Usage Effectiveness

Effectiveness = Power used by DC / Power used by IT equipment

Usually power used by non-IT equipment(cooling, fans) etc., should be far less to call an it an effective data center.

Policies:

Allocate VMs to Hosts and Schedule Cloudlets to Vm. Migrate Vm between Hosts in same or different data centers.
