4U rack servers are servers that can be mounted in a 19-inch rack and have a height of 4U (4 "units"). Compared to smaller rack servers, 4U rack servers offer several advantages. For one, they usually have more space for hardware components, making them more powerful and flexible. For another, they can usually accommodate larger hard drives and other peripherals, which can be beneficial for applications that require a lot of storage. 4U rack servers are also often expandable and offer features such as hot-swap capabilities, making them easy to adapt to changing needs. They are often used in data centers and other environments where high performance and flexibility are required.
