Energy Management Mechanisms in Virtualized Data Centers
Hai Jin · ZTE Technology Journal · 2012
There are certain power management issues that must be considered when a data center is virtualized.These issues include where virtual machines(VMs) should be placed,when VMs should be migrated,and which VMs should be migrated.Sorting and classifying VMs according to energy consumption is essential for managing,placing and migrating VMs and for consolidating servers.In this paper,we focus on energy saving in a data center,including scheduling management,initial placement and consolidation,and online migration strategies.We also discuss network traffic,cost,and load when VMs are being consolidated.
