Energy and Expenditure Aware Data Replication Strategy

Dynamic Energy and Expenditure Aware Data Replication Strategy

“…A. Experimental environment 1) Strategies parameters: DE2ARS uses [3] as an initial placement in our evaluations. In this evaluation section, all experiments associated with DE2ARS uses a value of propEC of 0.5.…”

“…As a control strategy, we used a static strategy that creates 3 replicas and places them randomly, called 3Rand. From the literature, we compare our strategy with 2 static replication strategies: MORM [5] and E2ARS [3]. We also compare our strategy with dynamic data replication strategies: PEPR [8] which takes provider's profit into account (with an income of 0.0081$ per task), and Boru [6] which considers energy and bandwidth consumption.…”

“…In [11], authors propose a static data replication strategy which models reads and writes energy consumption and expenditure where each objective is weighted. The static data replication strategy proposed by [3], called E2ARS, replicates in a 2 steps decision process. The first step leverages on heterogeneity to reduce both energy consumption and expenditure while the second step uses sleep states to reduce power consumption of unused nodes.…”

“…DE2ARS, which occurs after an initial static placement [3], aims to answer to an increasing and decreasing workload. To do so, we focus on the proportion of SLO violations in a sample.…”

“…In this paper, we propose a dynamic data replication strategy, DE2ARS (Dynamic Energy and Expenditure Aware data Replication Strategy), which occurs following an initial placement [3]. DE2ARS aims to reduce both energy consumption and expenditure while improving performance for the tenant.…”
