Datacenter simulation

The several ways to simulate a heterogeneous power aware data center based on a combination and allocation and selection policies applied for VM operations. Described below are few of them with a particular real PlanetLab workload. The remaining configuration parameters are in the Constants and PlanetLabConstants classes.

VM Allocation policy

• Iqr: Inter Quartile Range (IQR)
• Lr : Local Regression (LR)
• Lrr: Local Regression Robust (LRR)
• Mad: Median Absolute Deviation (MAD)
• Thr: The Static Threshold (THR)

• VM allocation policy and Maximum Correlation (MC) VM selection policy.

VM Selection policy

Maximum Correlation (MC)

Minimum Utilization (MU)

Minimum Migration Time (MMT)

Random Selection (RS)

A simulation of a heterogeneous power aware data center that only applied DVFS, but no dynamic optimization of the VM allocation. The adjustment of the hosts' power consumption according to their CPU utilization is happening in the PowerDatacenter class.

A simulation of a heterogeneous non-power aware data center: all hosts consume maximum power all the time.
