Toward Hierarchical Mixed Integer Programming for Pack-to-Swad Placement in Datacenters
Ye Xia, Maurício Tsugawa, J.A.B. Fortes, Shigang Chen · 2015
In this paper, we introduce a pack-centric approach to data center resource management by abstracting a system as a pack of resources and considering the mapping of these packs onto physical data center resource groups, called swads. The assignment of packs/VMs to swads/PMs is formulated as an integer optimization problem that can capture constraints related to the available resources, data center efficiency and customers' complex requirements. Scalability is achieved through a hierarchical decomposition method. We illustrate aspects of the proposed approach by describing and experimenting with a concrete and challenging resource allocation problem.
