This paper investigates the design issues and energy savings benefits of service prioritization in multi-tier web server clusters. In many services, classes of clients can be naturally assigned different priorities based on their per- formance requirements. We show that if the whole multi- tier system is effectively prioritized, additional power and energy savings are realizable while keeping an existing cluster-wide energy management technique, through ex- ploiting the different performance requirements of separate service classes. We find a simple prioritization scheme to be highly effective without requiring intrusive modifications to the system. In order to quantify its benefits, we perform extensive experimental evaluation on a real testbed. It is shown that the scheme significantlyimproves both total sys- tem power savings and energy efficiency, at the same time as improving throughput and enabling the system to meet per-class performance requirements. |
