Abstract:
“Cloud computing has evolved as the
next-generation platform for hosting applications ranging from sciences to
business and social networking to media content delivery. The numerous data
centers, employed to provide cloud services, consume large amounts of power for
their functioning and cooling. Improving power efficiency is become an
increasingly important task for many data centers for reasons such as
electricity cost, infrastructural limits, and negative environmental impact.
Power management is a challenging optimization problem due to the scale of modern
data centers and presence of conflicting objectives. Most published work
focuses on power management in computing nodes and the cooling facility in an
isolated manner. In this work, we use a combination of spatial subsetting and
thermal management to optimize the total power consumed by the computing nodes
and the cooling facility; and show that solutions, that do not consider these
interactions and are not holistic, do not necessarily result in minimum total
power consumption. We employ three evolutionary non-deterministic heuristics;
namely, Simulated Annealing (SA), Tabu Search (TS), and Simulated Evolution
(SimE) to find the best location of each virtual machine (VM) in a data center,
based on its computational power and data center heat recirculation model, to
optimize the total power consumption. Experimental results show that proposed
approach outperforms those heuristics published in previous studies.”
