一、What do 1U and 2U of the server mean? What do they mean?
1. "1U" repre sents the height unit of the server, which complies with the EIA (Electronic Industry Association) standard, 1U The height is 4.445 cm. This server is designed to save space and is ideal for installation in a rack.
2. The "2U" server is twice the height of the 1U server, which is 8.89 centimeters. Compared with 1U servers, 2U servers have improved scalability. For example, a 1U server typically can only accommodate up to 4 hard drives, while a 2U server can be expanded to 8. Similarly, 1U servers have up to 2 PCI slots, while 2U servers can provide up to 6 PCI slots, which enables 2U servers to support more hardware expansions.
3.U (Unit) is a unit that repre sents the external dimensions of the server and is designed to ensure that the server can be easily installed in a standard rack. There are screw holes on the rack for fixing the server, which are aligned with the screw holes on the server and fixed with screws. The standard width of a rack is 19 inches, so a 19-inch rack refers to a rack that meets this size specification.
The thickness of the 4.1U server is 4.445 cm, while the thickness of the 2U server is twice that of 1U, which is 8.89 cm. This standardization of sizes helps server manufacturers and users make selecting and configuring servers more efficient and convenient.
