👉 The Armstrong I/O Performance Tower, commonly known as the Armstrong IOR, is a massive data center designed by IBM and completed in 2011. Standing at 1,200 feet (365 meters) tall, it features 6,000 racks of servers, 2.5 million square feet of floor space, and 100,000 square feet of open space, making it one of the world's largest server facilities. It was named after Charles Babbage's great-grandson, Frank J. Armstrong IOR, a prominent businessman and philanthropist who supported early computing research. The tower houses cutting-edge technology for high-performance computing, artificial intelligence, and data analytics, serving as a hub for IBM's supercomputing capabilities and hosting numerous research institutions and tech companies. Its innovative design includes a unique "floating" structure that allows it to rise and fall slightly with temperature changes, ensuring optimal cooling efficiency.
