Data-center-infrastructure management (DCIM) is the integration[26] of information technology (IT) and facility management disciplines[27] to centralize monitoring, management and intelligent capacity planning of a data center's critical systems. Achieved through the implementation of specialized software, hardware and sensors, DCIM enables common, real-time monitoring and management platform for all interdependent systems across IT and facility infrastructures.

DCIM products can help data center managers identify and eliminate sources of risk[28] and improve availability of critical IT systems. They can also be used to identify interdependencies between facility and IT infrastructures to alert the facility manager to gaps in system redundancy, and provide dynamic, holistic benchmarks on power consumption and efficiency to measure the effectiveness of "green IT" initiatives.[29][30]

Important data center metrics include those regarding energy efficiency and utilization of servers, storage, and staff. In too many cases, disc capacity is vastly under-utilized and servers run at 20% utilization or less.[31] More effective automation tools can also improve the number of servers or virtual machines that a single admin can handle.

DCIM providers are increasingly linking with computational fluid dynamics providers to predict complex airflow patterns in the data center. The CFD component is necessary to quantify the impact of planned future changes on cooling resilience, capacity and efficiency.[32]
