It is important to know that the U of 1U, 2U, 3U, etc., refers to “unit”, which means “unit” in Chinese.

Generally, we call it “rack unit”. This concept was widely used in server racks in the early days. 1U server,

2U server, 3U server, 4U server, etc. By default, they are 1U server, 2U server, 3U server, and 4U server.

But now with the continuous expansion of the computer room or data center, such as enterprise-class router,

switch, AC, etc., must also use the rack to carry management. So now we’re talking about racks.

However, there is a strict distinction to be made here. The server rack is generally called the server rack, and

the network rack is generally called the network rack. Generally, the two racks are not mixed.

A server rack is different from a network rack

Server racks are generally more robust than network racks, and some have cooling units.

The server rack is also built a little deeper than the network rack. And the network rack in the number

of equipment or the rack is relatively small, but also can be nailed to the wall, very light.

What is a rack? What does the frame look like?

A rack is a frame structure designed specifically to house and manage IT equipment.

A server rack cabinet houses IT equipment just like a regular rack, but it is usually enclosed on all sides,

meaning it has doors at the front and back of the rack and walls on each side.
