Addressing the stranded power problem in datacenters using storage workload characterization
Sriram Sankar, Kushagra Vaid · 2010
Datacenter operators face unique challenges to optimally provision power among deployed servers. Allocated server power is frequently over-provisioned and this results in stranding of available datacenter power capacity. Standardized power efficiency benchmarks like SPECpower_ssj2008 can be used for determining power allocation, in conjunction with methodologies to estimate the contribution from the disk subsystem. In this paper, we explore a trace-driven methodology for determining power contribution of the storage components. We show the benefits of this methodology as opposed to typical power provisioning used in the industry.
