- W2744167479 abstract "Multi-Tenant Data Center (MTDC) operators can increase their profits by oversubscribing their power infrastructure. However, without an appropriate power control mechanism, oversubscription can lead to expensive unplanned service outages. We propose a new power control mechanism, LOCAP (LOCAl Price for power), as a means of 1) incentivizing tenants to reduce power use to save energy and 2) controlling tenant power use to prevent over capacity cases. LOCAP is a real-time power pricing mechanism for setting local power price based on an optimization approach where the objective is to maximize aggregate tenant revenue while ensuring that total data center power consumption does not exceed capacity. Local price is set by the data center operator to reflect the current total power demand. Individual tenants use the current local price and their Service Level Agreement (SLA) parameters to determine how much power to consume. We evaluate LOCAP using workloads from real data center traces and compare with a no oversubscription case and with COOP, an existing market-based mechanism. Simulation results show that our new mechanism benefits both the tenant, by decreasing leasing costs, and the operator, by decreasing capital expense, and achieves the goal of keeping total power consumption under the data center power capacity limit while reducing overall energy use." @default.
