What is a rack-type server?

The rack-type server does not look like a computer, but like a switch, it has 1U (1u=1.75 inches), 2U, 4U and other specifications. Rack-mounted servers are installed in a standard 19-inch cabinet. This structure is more of a functional server.

For information service enterprises (such as ISP/ICP/ISV/IDC), select the server first to consider the size of the server, power consumption, heat and other physical parameters, because information services enterprises usually use large private rooms to unify the deployment and management of a large number of server resources, the room is usually equipped with strict security measures, Good cooling system, multiple backup of the power system, the cost of its room is quite expensive. How to deploy more servers in a limited space is directly related to the cost of services to the enterprise, usually using a machine size to meet the 19-inch industrial standard rack-type server.

Rack-type servers also have a variety of specifications, such as 1U (4.45cm High), 2U, 4U, 6U, 8U, and so on. Typically 1U rack-less servers are the most space-saving, but poor performance and scalability are appropriate for some of the business's relatively fixed areas of use. More than 4U of products with high performance, scalability, and generally support more than 4 high-performance processors and a large number of standard hot-swappable parts. Management is also very convenient, manufacturers usually provide people with appropriate management and monitoring tools, suitable for large access to key applications, but the volume is large, space utilization is not high.
