We present Neptune - the resource director of Océano, apolicy driven fabric management system that dynamicallyreconfigures resources in a computing utility cluster.Neptune implements an on-line control mechanism subject to policy-based performance and resource configuration objectives.Neptune reassigns servers and bandwidth among a set of service domains,based on pre-defined policy, in response to workload changes. It builds and executes a reconfiguration plan through a planningframework, breaking reconfiguration objectives into individual tasks delegated to set of lower level resource managers.We describe an example decision policy algorithm that we implemented and demonstrated in an 80 server multi-domain computing utility.
