Who decided the dimensions of data center racks? Go back 100 years!

The connection between railway switching and data centers may seem unlikely for most, but many point to the width of a train car as a major influencer of IT racks’ and enclosures’ dimensions. By tracing their origins to deployments in railway signaling, many people believe the 19-inch equipment bay was chosen because the rack could fit within a train car. Since the initial decision to have a 19-inch equipment bay was made, it has not changed for almost a century.
