Rackmount servers are specialized computer systems designed to be installed in a rack, which is a standardized frame that holds multiple servers and networking equipment. These servers are typically 1U to 4U in height, allowing for efficient use of space in data centers. Their design promotes better airflow and cooling, which is essential for maintaining optimal performance. These servers are commonly used in enterprise environments for tasks such as hosting websites, managing databases, and running applications. Their modular nature allows for easy upgrades and maintenance, making them a popular choice for businesses that require reliable and scalable computing solutions.
