Guaranteeing performance based on time-stability for energy-efficient data centers Academic Article

abstract

• Copyright 2016 IIE. We consider a system of multiple parallel single-server queues where servers are heterogeneous with resources of different capacities and can be powered on or off while running at different speeds when they are powered on. In addition, we assume that application requests are heterogeneous with different workload distributions and resource requirements and the arrival, rates of request are time-varying. Managing such a heterogeneous, transient, and non-stationary system is a tremendous challenge. We take an unconventional approach, in that we force the queue lengths in each powered-on server to be time-stable (i.e., stationary). It allows the operators to guarantee performance and effectively monitor the system. We formulate a mixed-integer program to minimize energy costs while satisfying time-stability. Simulation results show that our suggested approach can stabilize queue length distributions and provide probabilistic performance guarantees on waiting times.
