WattDB - A Cluster of Wimpy Processing Nodes to Approximate Energy Proportionality
نویسندگان
چکیده
Energy efficiency gained a lot of attention lately. In data management research, much work focused around the use and optimization of SSDs as middle-tier buffers or replacements of HDDs. Initial research goals aimed at performance improvement and energy saving when processing large volumes of data stored on external devices. Using SSDs, data-intensive applications achieved impressive performance gains, whereas energy saving was limited to the amount needed by the persistent storage, typically in the range of 10 – 20%.

WattDB - A Journey towards Energy E ciency
Due to their narrow power spectrum between idle and full utilization [2], satisfactory energy e ciency of servers can only be reached in the peak-performance range, whereas energy e ciency obtained for lower activity levels is far from being optimal. Hence, this hardware property obviates a desired energy proportionality or minimal energy use for the entire range of system utilization. To appro...
متن کاملEnergy Efficiency Is Not Enough, Energy Proportionality Is Needed!
Due to the energy consumption/resource utilization characteristics of todays centralized DB servers, the fastest configuration is also the most energy-efficient one. Extensive use of SSDs alone cannot enable a fundamental change of this overall picture, because the storagerelated energy consumption is typically only a little fraction of the overall energy budget. Even, when this storage-related...
متن کاملTowards an Energy-Proportional Storage System using a Cluster of Wimpy Nodes
Previous DB research clearly concluded that the most energy-efficient configuration of a single-server DBMS is typically the highest performing one. This observation is certainly true if we focus in isolation on specific applications where the DBMS can steadily run in the peak-performance range. Because we noticed that typical DBMS activity levels—or its average system utilization—are much lowe...
متن کاملApproximating an Energy-Proportional DBMS by a Dynamic Cluster of Nodes
The most energy-efficient configuration of a single-server DBMS is the highest performing one, if we exclusively focus on specific applications where the DBMS can steadily run in the peak-performance range. However, typical DBMS activity levels—or their average system utilization—are much lower and their energy use is far from being energy proportional. Built of commodity hardware, WattDB—a dis...
متن کاملEnergy and Performance - Can a Wimpy-Node Cluster Challenge a Brawny Server
Traditional DBMS servers are usually over-provisioned for most of their daily workloads and, because they do not show good energy proportionality, waste a lot of energy while underutilized. A cluster of small (wimpy) servers, where the number of nodes can dynamically adjust to the current workload, might offer better energy characteristics for these workloads. Yet, clusters suffer from ”frictio...
