Why Are Data Centers Important for Business and Organizations

Data centers are the backbone of modern business, providing a secure and reliable infrastructure for storing and processing vast amounts of data. They enable companies to operate 24/7, without worrying about data loss or system downtime.

Data centers house the servers and equipment that power online services, allowing businesses to reach customers and partners worldwide. This global reach is a major factor in their importance.

Data centers also provide a competitive advantage, enabling companies to innovate and stay ahead of the curve. Companies that invest in data centers are better equipped to respond to changing market conditions and customer needs.

By providing a scalable and flexible infrastructure, data centers allow businesses to grow and adapt quickly, without being held back by outdated technology or infrastructure limitations.

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.

Data centers require robust backup power systems to ensure continuous operation. This typically involves uninterruptible power supplies, battery banks, and diesel or gas turbine generators.

Redundancy is key in electrical systems, with many data centers employing N+1 redundancy to prevent single points of failure. Static transfer switches can also be used to ensure a seamless switchover from one power supply to another in the event of a failure.

The increased demand for electricity from data centers has led to concerns about electricity prices. In some regions, like Santa Clara, California, and upstate New York, data centers have driven up electricity prices.

Backup power systems are designed to prevent data center outages, typically consisting of uninterruptible power supplies, battery banks, and/or diesel/gas turbine generators.

To ensure reliability, all elements of the electrical systems, including backup systems, are given redundant copies to prevent single points of failure.

Critical servers are often connected to both the A-side and B-side power feeds to achieve N+1 redundancy in the systems.

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.

Data centers offer a high level of security, protecting sensitive information with multiple layers of security measures in place, such as biometric authentication, surveillance cameras, firewalls, and encryption.

Physical access to data centers is restricted, often starting with fencing, bollards, and mantraps. Video camera surveillance and permanent security guards are almost always present in large or sensitive data centers.

Fingerprint recognition mantraps are becoming increasingly common, while logging access is required by some data protection regulations, often linked to access control systems. Multiple log entries can occur at the main entrance, internal rooms, and equipment cabinets.

Redundancy and disaster recovery capabilities are also crucial, ensuring data availability and quick recovery during natural disasters or cyber-attacks.

Fire protection is a crucial aspect of data center security. Data centers feature fire protection systems, including passive and active design elements, as well as implementation of fire prevention programs in operations.

Smoke detectors are usually installed to provide early warning of a fire at its incipient stage. This is a vital measure to prevent damage and ensure the safety of personnel.

In the main room, Wet Pipe-based Systems are not usually used due to the fragile nature of circuit-boards. However, other systems can be used in the rest of the facility or in closed systems, such as sprinkler systems and misting systems using high pressure to create extremely small water droplets.

For sensitive areas, gaseous fire suppression systems are often used. Halon gas was once the most popular choice, but it's no longer used due to its negative environmental effects.

Physical barriers like fencing and bollards are often used to restrict access to data centers.

Data centers typically have video camera surveillance and permanent security guards, especially if they're large or contain sensitive information.

Fingerprint recognition mantraps are becoming increasingly common for added security.

Logging access is required by some data protection regulations, and it's often linked to access control systems.

Multiple log entries are made at various points, including the main entrance, internal rooms, and equipment cabinets.

Access control at cabinets can be integrated with intelligent power distribution units, allowing locks to be networked through the same appliance.

Software backup is a crucial aspect of security and data protection. Onsite data backup is a traditional option that offers immediate availability of backed-up data.

Onsite backup is often preferred for its speed and convenience. This is because the data is stored locally, making it easily accessible in case of an emergency.

However, onsite backup also has its limitations. For businesses that rely heavily on data, onsite backup alone may not be sufficient.

One way to address this concern is to consider offsite backup options. Offsite backup provides an additional layer of security and protection against data loss.

Offsite backup is often used in conjunction with onsite backup to ensure maximum data protection. This can be achieved through cloud storage or other remote backup solutions.

Here are some non-mutually exclusive options for data backup:

Data centers come in various forms to meet different business needs. Enterprise data centers are owned and managed by a single organization to support their internal IT needs.

There are four main types of data centers: enterprise, colocation, cloud, modular, and edge. Enterprise data centers are the most common type, while colocation data centers offer shared resources to multiple organizations. Cloud data centers provide virtualized resources over the internet, and modular data centers are portable and self-contained. Edge data centers are smaller facilities located closer to end users for faster access.

Colocation data centers are ideal for businesses that want to access a data center without the need for a dedicated facility. Cloud data centers, on the other hand, offer flexibility and scalability. Enterprise data centers, as mentioned earlier, are owned and managed by a single organization.

Here's a quick rundown of the four main types of data centers:

Data centers also come in different tiers, each with increasing levels of redundancy, availability, and fault tolerance. The Uptime Institute outlines four tiers of data centers, with Tier 4 offering the highest level of redundancy and fault tolerance.

Data centers come in different shapes and sizes, and understanding the types can help you make informed decisions about your organization's IT needs. Enterprise data centers are owned by a single organization and used to support their internal IT needs.

Colocation data centers are a popular option for businesses that don't need a dedicated facility. They provide shared computing resources and services, allowing multiple organizations to access the benefits of a data center without the need for their own dedicated space.

Cloud data centers, operated by cloud service providers, offer virtualized computing resources and services over the internet. This can be a convenient option for businesses that need flexibility and scalability.

Modular data centers are portable, self-contained computing environments that can be deployable in remote locations or areas with limited space or infrastructure. They're often used in situations where a traditional data center wouldn't be feasible.

Edge data centers are smaller facilities located closer to end users, enabling faster and more efficient access to computing resources and services. This can be especially beneficial for organizations that need to process large amounts of data in real-time.

Here's a quick rundown of the different types of data centers:

Scalability is a key benefit of data centers, allowing businesses to easily match their storage infrastructure to changing equipment needs. Companies can scale their infrastructure up or down as needed, making it ideal for businesses experiencing rapid growth or seasonal changes in demand.
