Server Rack
Also known as: Server Cabinet · Network Rack · 19-inch Rack
A server rack is a standardized 19-inch enclosure that holds servers, switches, patch panels, and a UPS in an orderly, protected, coolable way.
A server rack is an enclosure built to the 19-inch standard, in which servers, switches, patch panels, a UPS, and other equipment are mounted one above the other. It exists because active equipment sitting loose on desks or shelves is neither adequately protected nor cleanly cabled, and cooling individual devices separately is hard to control.
In practice, a server rack is recognizable by its side mounting rails spaced 19 inches apart, into which equipment is screwed in based on its rack unit height, along with lockable doors and often fans for airflow. Cables run through cable channels or management arms to keep them out of the way of airflow and maintenance work.
A common mistake is placing a server rack in whatever spare room happens to be available, such as a cleaning closet or storage room with no ventilation: without air exchange, the temperature inside the rack climbs, shortening the equipment's lifespan. A rack chosen too small, with no room to grow, also turns every expansion into an improvisation.
What it means in practice
In many small and midsize businesses, the server rack ends up wherever there happened to be space, rather than in a location with cooling, protected power, and controlled access. NDVDL plans server racks with spare capacity, cooling, and access protection built in from the start.
