When it comes to data storage and server racks, sometimes off the rack isn’t the best way to stay on track.
In practice, there are many circumstances in which standard racks and cabinets might not be up to the task — for example, cable-heavy data centers, facilities located in areas prone to earthquakes or other vibration, or in spaces that make the homes on HGTV’s "Tiny House, Big Living" look like mansions. Sometimes, specialized storage is needed to easily repurpose it from one location to another.
