Data center density continues to increase as companies seek to generate greater performance from their IT infrastructure. However, higher density means more network cables within each server rack, which can decrease cooling efficiency by impeding airflow. That’s one of several reasons why server rack cable management is vitally important.
The dynamic nature of today’s data centers also demands “slide in, slide out” component mounting. Without proper management, cables can limit the accessibility, flexibility, and scalability of cabinets. This equates to reduced IT staff efficiency and increased costs.
Server rack cable management plays a vital role in the proper rack setup. It also reduces the risk of crosstalk or signal interference and system downtime due to link failure or cable damage.
Benefits of Server Rack Cable Management
Well-managed cables within the server rack or cabinet bring several connectivity benefits to the data center.
Improved Airflow
When network cables are gathered neatly, they are less likely to impede airflow. Proper airflow is essential for maximizing cooling efficiency and reducing the risk of hotspots. Cable management also maximizes the usable space within the cabinet.
Reduced Risk of Downtime
It takes longer to troubleshoot issues if cables are a tangled mess. Effective cable management makes it easier for technicians to access equipment and find the source of problems.
Cable Protection
High-quality cable managers are designed to minimize excessive bending or crimping, reducing the risk of cable damage. Additionally, power and network cables can be separated to minimize crosstalk and interference.
Greater Flexibility
Cable management makes it easier to add, move or consolidate equipment. Technicians can easily identify cables and understand what goes where, and equipment can be removed from the rack without causing problems.
Types of Cable Managers
There are two main types of server rack cable managers:
Vertical Cable Managers
Vertical cable managers are designed to organize cables in the “zero U” space in the back of the cabinet. They consist of a vertical bar that attaches to the rack using bolts, brackets, or quick-mount vertical buttons.
There are several types available. Some have D-rings for easy routing of bundled cables while minimizing cable strain. Others have “fingers” that are spaced to maintain the bend radius of cables. These are available in single- and double-sided models and generally have snap-on covers or hinged doors to keep cables in position and protect them from dust and damage.
Vertical cable managers are available in metal and plastic, with heights of up to 48U and widths of up to 10 inches. Three- to five-inch widths are the most popular.
Horizontal Cable Managers
Horizontal cable managers are often used in environments that have frequent moves, adds, and changes to organize patch cords that connect individual pieces of equipment. They are typically 19 inches wide to fit standard cabinet widths but may be 1U to 4U in height.
Like vertical cable managers, horizontal cable managers come in several types. Open designs with D-rings are highly flexible and can support copper, fiber, and coax cables. Closed designs with flexible fingers may be single- or double-sided. Bend radius control reduces the risk of kinks that shorten cable life and cause network service interruptions.
