Data centers have come a long way since the 1940s, when they were first born out of huge computer rooms like ENIAC. These early computer systems were complex to operate and maintain, requiring specialized rooms with racks, cable trays, and cooling mechanisms.

In the 1960s, the creation of mainframe computers by IBM led to the development of dedicated mainframe rooms, which marked the birth of the first data centers. Some of these rooms even needed their own free-standing buildings.

The term "data center" started gaining traction in the 1990s, as IT operations expanded and inexpensive networking equipment became available. This made it possible to store all a company's servers in a single room within the company.

A boom of data centers occurred during the dot-com bubble of 1997-2000, as companies needed fast internet connectivity and non-stop operation to deploy systems and establish a presence on the internet. Many companies built large internet data centers (IDCs) to meet this demand.

By 2030, the U.S. data center power consumption could range from 4.6% to 9.1% of the country's generation, according to a study published by the Electric Power Research Institute (EPRI) in May 2024. As of 2023, about 80% of U.S. data center load was concentrated in 15 states, led by Virginia and Texas.

Here's a brief timeline of the evolution of data centers:

Modern data centers must meet high standards for security and performance to minimize the chances of a security breach and ensure the integrity of their hosted computer environment.

Industry research shows that data centers older than seven years are considered obsolete, which is why modernization is crucial. The growth in data is a significant factor driving the need for data centers to modernize, with IDC predicting 163 zettabytes of data by 2025.

When designing a data center, availability expectations and site selection are key considerations. Availability expectations mean that the costs of avoiding downtime should not exceed the cost of the downtime itself. Site selection involves choosing a location that is close to power grids, telecommunications infrastructure, and emergency services.

Here are some key factors to consider when selecting a site:

Availability expectations should be carefully considered, as the costs of avoiding downtime should not exceed the cost of the downtime itself.

Site selection is crucial, and factors such as proximity to power grids, telecommunications infrastructure, and networking services should be taken into account.

Location factors also include transportation lines and emergency services, which can impact the overall design and functionality of a project.

Other considerations for site selection include neighboring power drains, geological risks, and climate, which can affect cooling costs.

Here are some key site selection factors to keep in mind:

Data centers have come a long way, and modernization is crucial to enhance performance and energy efficiency. The average age of a data center is nine years old, according to International Data Corporation (IDC), and Gartner warns that data centers older than seven years are obsolete.

The growth in data is a significant factor driving the need for modernization, with 163 zettabytes expected by 2025. This growth has been a concern for a while, with industry experts warning about obsolete equipment as far back as 2007.

Data center staff are aging faster than the equipment, a concern that shifted in 2018. This highlights the importance of not only modernizing equipment but also ensuring that staff are up-to-date with the latest skills and technologies.

To meet the demands of modern data centers, a secure environment is essential to minimize the chances of a security breach. This requires high standards for assuring the integrity and functionality of the hosted computer environment.

Raised Floor is a crucial component in designing computer centers. It was first introduced by IBM in 1956.

The first raised floor was made to allow access for wiring. This was a game-changer for efficient cable management.

The raised floor became more common in the 1970s, allowing cool air to circulate more efficiently. This led to better temperature control in computer rooms.

Telcordia Technologies developed a raised floor standards guide named GR-2930, which is a benchmark for designing raised floors.

Static transfer switches are sometimes used to ensure instantaneous switchover from one supply to the other in the event of a power failure.

Data centers are a significant contributor to increased electricity demand, with the IEA expecting global data center demand for electricity to double between 2022 and 2026.

This surge in demand is largely driven by the growth of cryptomining and artificial intelligence, which is expected to increase the US share of the electricity market going to data centers from 4% to 6% over the same period.

Thermal zone mapping uses sensors and computer modeling to create a three-dimensional image of the hot and cool zones in a data center.

This information can help to identify optimal positioning of data center equipment. Critical servers might be placed in a cool zone that is serviced by redundant AC units.

Energy efficiency is crucial for data centers, with some facilities having power densities more than 100 times that of a typical office building.

The most commonly used energy efficiency metric is power usage effectiveness (PUE), which measures the percentage of power used by overhead devices. The average USA data center has a PUE of 2.0, but state-of-the-art data centers have achieved PUEs as low as 1.01.

To qualify for the Energy Star rating, a data center must be within the top quartile in energy efficiency of all reported facilities. California's Title 24 mandates that every newly constructed data center must have some form of airflow containment in place to optimize energy efficiency.

Data centers can consume a significant amount of energy, with a high-availability data center estimated to have a 1 megawatt (MW) demand and consume $20,000,000 in electricity over its lifetime.

Cooling represents 35% to 45% of the data center's total cost of ownership, which is why optimizing IT refresh rates and increasing server utilization can help conserve energy.

The Open Compute Project (OCP) has developed and published open standards for greener data center computing technologies, which have led to significant energy efficiency improvements.

Google's 48V DC shallow data center rack design eliminated multiple transformers, achieving a 30% increase in energy efficiency. Sales for data center hardware built to OCP designs topped $1.2 billion in 2017 and are expected to reach $6 billion by 2021.

Liquid cooling throughout a data center can capture all heat with water, making it an attractive alternative to heat pumps.
