How a Server Rack Works

The key to any data center is getting enough servers in one place to make it practical; which is where a server rack comes in. Unlike conventional towers, which use up valuable floor space, a rack lets you stack servers and make the most out of your available space.

What is a Rackmount Server?

Server space is generally described in terms of rackmount units, denoted by a capital letter U. Each unit represents a space 19 inches wide by 1.75 inches high, which offers the minimum of room necessary to hold a single server. Going with a server rack with systems like the Dell PowerEdge provides a number of advantages over standalone units:

  • Cable Management: Most rack-mount solutions offer integrated cable management solutions where you can easily access all the cables at once; some offer cable management arms that let you swing everything out of the way as needed. Good management also simplifies power delivery, since all the servers are in the same place.
  • Accessibility: Once installed all your PowerEdge servers can just slide out of their bays. It makes hot-swap drives much easier to get to, as well as RAM and other components.

Why a 1U Server?

Choosing the right PowerEdge is a matter of balancing your needs against each other. Dell makes a lot of rackmount systems in different sizes and capacities in order to serve different markets.

  • 1U Server: Usually holds one or two processors, while still providing room for storage and sometimes even optical drives. The big advantage here is size. You can start small with a single PowerEdge with 64 GB RAM and quickly scale up or down simply by adding or removing additional servers as necessary. The compact chassis also means lower power usage, which along with temperature is an important factor for any server room. Many 1U models offer one and two-socket options depending on requirements.
  • 2U Server: Using twice the height in the same 19-inch rack, a 2U PowerEdge or even larger server offers more internal room for expansion cards and hard drives. The big advantage here is that you can expand your existing servers more effectively than with a smaller unit as they have room for more drives and offer more PCIe slots. The greater size also means more cooling capacity, which makes four-socket Xeon systems practical. Options like fiber channel provide all the bandwidth you need.

Running Servers

Running mission-critical servers also takes a number of accessories including a KVM and monitor for local access when necessary. There's no need to provide one for each server when you can simply use one on each rack and save space. Your end users can often manage everything they need to handle remotely.
