As IT departments and storage planners look at best practices and technologies to reduce ownership costs, a tiered storage approach should be investigated. Tiered storage enables data and applications to be stored on tiers that vary in performance, cost, availability, recoverability, etc. The potential to lower storage-related operating costs (OPEX) over three years with tiered storage has been measured at around 15 percent, when compared to a single-tiered architecture. This paper characterizes cost-savings areas, calculation methods, and proofs related to reducing labor, capital expense (CAPEX), waste, and infrastructure with a tiered storage architecture.
