It's important to note that 37 percent of data centers still have racks of less than 10kW. There are three key reasons why these data centers have not seen substantial increases in rack density. Server virtualization has been around for decades, and containerization has been used for several years.
Data center power density, measured in kilowatts (kW) per server rack, is crucial for optimizing design and operations. Higher density allows more computing power in a smaller footprint, potentially reducing capital expenditures and enhancing operational efficiency. Rack power densities vary by IT equipment and workload intensity:
As a result, data center rack densities are increasing. Rack density refers to the amount of power consumed by all of the IT equipment in the rack. For many years, rack densities averaged 2kW to 5kW. That's not the case anymore. According to AFCOM's 2024 State of the Data Center Report, average rack density now sits around 12 kW.
