Bounding the Resource Savings of Utility Computing Models

Andrzejak, Artur; Arlitt, Martin; Rolia, Jerry

HPL-2002-339

Keyword(s): utility computing; resource savings; grid computing

Abstract: In this paper we characterize resource usage in six data centers with approximately 1,000 servers. The results substantiate common knowledge that computing resources are typically under-utilized. Utility computing has been proposed as a way of increasing utilization and hence efficiency. Using an off-line integer programming model we bound the potential gain in efficiency for several different utility computing models. In a detailed study of a subset of the data center servers, we found that utility computing offered the potential to reduce the peak and mean number of CPUs needed by up to 53% and 79%, respectively.
