CVM is virtual. Generally speaking, there is no such thing as 1U. In server hosting, the size of the server is 1U.

The server hosting fee of the computer room is calculated according to the amount of space occupied, so the hosting cost should consider the specifications of rack 1U and 2U. 1U and 2U refer to the size of the cabinet occupied by the service. 1U is a relatively small server, and the hosting cost is less than 2U.

In fact, U is a unit that represents the external size of the server, an acronym for unit, and the detailed size is determined by the American Electronic Industry Association (EIA), an industry group.

The reason for setting the size of the server is to keep the server in the right size so that it can be placed on an iron or aluminum rack. There is a screw hole for fixing the server on the rack. Align it with the screw hole of the server and fix it with screws.

The dimensions specified for hosting are the width (48.26cm=19 inches) and height (multiples of 4.445cm) of the server. Because it is 19 inches wide, a rack that meets this requirement is sometimes called a "19-inch rack".

The thickness is based on 4.445cm. 1U is 4.445cm.2U is twice as much as 1U and 8.89cm. In other words, the so-called "1U PC server" is a product whose appearance meets the EIA specification and the thickness is 4.445cm. Products designed to fit into 19-inch cabinets are generally referred to as rack servers.

In general, there are two types of servers: tower and blade. The blade type is required to be placed on a special rack, and the specification is expressed by the index "U". There are usually 1U, 2U, 4U and so on. A single cabinet rack can hold 16U blades, that is, 16 1U or 8 2U.
