Maximizing server utilization within a datacenter

摘要

A method of maximizing server utilization within a datacenter comprising collocating a number of workloads to a subset of a number of physical servers within a datacenter, adjusting access to resources by critical and non-critical workloads, isolating a number of critical workloads that share resources to the subset of resource instances, and controlling resource utilization of the collocated workloads. A system for collocating workloads in a datacenter, the system comprising a number of servers communicatively coupled to each other and a collocation module that receives information from each server and decides whether to leave a workload running on one of any of the servers on that server, or migrate a workload running on one of the number of servers to another server.

1. A system for collocating workloads in a datacenter, the system comprising:
a number of servers communicatively coupled to each other; a collocation module to receive information from each server and decide whether to migrate a workload running on one of the number of servers to another server; a daemon to find and periodically create a report about each servers' resource utilization on that server; a power measurement module to compile data defining the power consumption of the server; and wherein the collocation module compares a utility metric of a critical workload with a service level agreement (SLA) and when:
the utility metric is not in violation of the defined SLA, an SLA violation counter is decremented for the critical workload;the utility metric is in violation of the defined SLA, the SLA violation counter is incremented for the critical workload.
