Major companies utilize direct connections to each other within highly secure data centers like the Dallas Infomart, effectively bypassing the public internet for critical services. These interconnected facilities, exemplified by Equinix, offer advanced security, efficient cooling, and innovative networking solutions like Equinix Fabric to enable high-speed, low-latency communication globally.
The world's biggest companies bypass the public internet by using direct connections to each other within specialized data centers, essentially acting as neighbors in a digital ecosystem.
The Dallas Infomart, spanning 1.5 million square feet, serves as a central hub for the internet, housing 8,700 fiber strands, multiple internet exchanges, and over 140 networks peering at terabit speeds, making it one of the most connected buildings globally.
Data centers employ intense, multi-layered security measures to protect billions of dollars worth of equipment and a significant portion of the internet. This includes strict access control at reception, ID verification, biometric authentication, and 'man traps' that prevent tailgating by requiring one door to close before another opens.
Upon gaining initial entry, visitors and personnel are continuously monitored by cameras and must be escorted everywhere, highlighting the stringent security protocols within the facility.
As a customer, access is restricted to their specific equipment, floor, and cage, each requiring separate badge and fingerprint authentication, demonstrating a defense-in-depth security approach.
Major companies, including AI firms like Groq, house their servers in these data centers, with measures like unmarked server racks designed to prevent competitors from identifying their specific equipment or networking hardware, thus protecting trade secrets.
Equinix data centers utilize blue lighting primarily for aesthetic appeal and as a subtle security measure, making it more challenging to read equipment labels and identify vendors used by customers.
Equinix facilitates equipment deployment, often pre-configuring racks for customers. These racks are placed within secure cages, which can vary in design from open-top (still heavily monitored) to fully enclosed, offering different levels of privacy and security tailored to customer needs.
Equinix technicians undergo a rigorous interview process that includes practical tests such as building cables, running fiber, and splicing, ensuring a high level of technical competency among staff.
The data center utilizes slab floors to support the immense weight of server racks and employs a unique cooling method where cool air is pushed from the side, with hot air rising and exiting through ventilation, an alternative to traditional raised-floor cooling.
The cooling system on the roof operates much like a gaming computer's liquid cooling, featuring self-contained radiator units that cool liquid which then circulates to chill servers. These units can be air-lifted for expansion, supported by giant water tanks for buffer and backup.
An extensive generator yard provides backup power, enabling the data center to run on diesel generators for a total of 36 hours at full load, ensuring continuous operation even during grid power failures.
Traditional connections to cloud providers (AWS, GCP, Azure) via the public internet often suffer from unreliable latency and frequent drops due to uncontrolled routing and traffic congestion, similar to unpredictable road trips.
Equinix enables companies to bypass the unreliable public internet by leveraging its highly connected data centers, which act as direct fiber highways for major cloud and network providers.
The InfoMart (DA1), a retro-futuristic building from the 1980s, is strategically situated at a major convergence of fiber optic highways, making it a critical 'Grand Central Station' for internet traffic.
Equinix pioneered the concept of carrier-neutral data centers, allowing any telecom company or network provider (e.g., AT&T, Verizon, Lumen) to establish a network node, fostering a competitive and highly dense network environment.
Equinix acquired the Infomart (DA1) and connected it to its newer DA11 facility with a massive underground fiber highway, enabling seamless cross-connections between various networks and cloud services located in either building.
A cross connect is a physical cable that directly links a customer's equipment to a network provider or cloud service within the data center, traditionally requiring advance ordering and incurring costs for each connection.
Equinix Fabric, a software-defined networking solution, replaces the need for multiple physical cross connects. It allows customers to establish a single physical connection and then create multiple virtual connections to over 3,000 customers and cloud providers (like AWS, Azure, GCP) within seconds, offering bandwidth from 10 Mbps to 50 Gbps via a user portal.
Customers connected to one Equinix data center gain access to the entire global Equinix network, allowing them to connect to other Equinix data centers and cloud locations worldwide without traversing the public internet, using Equinix's 'special HOV lane'.
Beyond the advanced technology and infrastructure, the people who work at Equinix, many with over 20 years of tenure, are fundamental to the data center's operation and the overall functioning of the internet, highlighting that human passion and dedication drive technological success.
What makes this data center run is the people.
