This paper consolidates the industry standards, metrics, and trends that defined the DCIM landscape in 2021, creating a structured "index" of the most critical parameters used for benchmarking and management during that year. Date: December 2021 Subject: Data Center Infrastructure Management, Operational Efficiency, Sustainability Metrics. Abstract The year 2021 marked a pivotal transition in Data Center Infrastructure Management (DCIM). As the global data center market rebounded from the initial disruptions of the COVID-19 pandemic, the focus shifted rapidly toward hyperscale expansion, edge computing, and aggressive sustainability targets. This paper establishes a "2021 DCIM Index," defining the critical metrics and operational parameters that defined successful data center management during this period. By analyzing Power Usage Effectiveness (PUE), Carbon Usage Effectiveness (CUE), Server Utilization, and the emerging role of AI-driven orchestration, this document provides a benchmark for operators assessing their infrastructure maturity against the 2021 industry standard. 1. Introduction Data Center Infrastructure Management (DCIM) serves as the convergence point for information technology (IT) and facilities management. In 2021, the discipline matured from simple monitoring dashboards to sophisticated predictive analytics platforms. The "DCIM Index" referred to in this paper is not a single financial metric but a composite index of operational Key Performance Indicators (KPIs) that defined the health, efficiency, and sustainability of data centers in 2021.
