Description
The MIT Tier-2 computing center, established in 2006, has been a long-standing contributor to CMS computing. As hardware ages and computing demands evolve, we are undertaking a major redesign of the center’s infrastructure. In this talk, we present a holistic cost analysis that includes not only hardware purchases but also power consumption, cooling, and rack space—factors often excluded from conventional cost models. Using power measurements under typical CMS workloads, we evaluate the cost-effectiveness of maintaining aging hardware versus timely replacement, and propose optimal hardware retirement and procurement policies.
