Influence of availability on the cost analysis of solar powered data centers with AC and DC architecture and mirroring functionality

This paper addresses availability of power infrastructure in data centers and associated costs for downtime. Special attention is given to modeling of solar power sources in terms of availability as well as their implementation into critical infrastructure and the justification for their implementation from cost perspective. Influence on overall electrical reliability and availability of infrastructure is shown in different topologies. Architecture of the topologies is based on both alternating current (AC) and direct current (DC) 400V distributions. Results of reliability and availability calculations derive from models based on Dynamic Fault Tree Analysis (DFTA).
