Server racks are much more than just support for IT equipment. They help to create a consistent and manageable IT environment that allows for greater operational efficiency. They also facilitate power distribution, airflow management, cabling management, and other critical functions in the data center infrastructure.
When choosing server racks, it’s essential to consider the following factors:
What size server rack do I need?
Racks must be large enough to accommodate the IT equipment. The mounting area of server racks is generally 19 inches wide, but the depth can vary significantly. A deeper cabinet may be needed to accommodate larger equipment and allow room for power distribution units (PDUs) and cabling. Rack units (Us) are used to specify the height of the equipment and the vertical mounting space of the cabinet. Taller racks hold more equipment, but there are operational drawbacks.
Server Rack Airflow Management
Server rack airflow management is essential to maximize the life of your equipment. Two- and four-post racks are open, so airflow isn’t much of a consideration. But enclosed server cabinets require airflow features to prevent heat buildup and ensure cooling efficiency. Data center managers are also concerned with how to avoid the mixing of hot and cold air with accessories like blanking panels. Perforated doors allow chilled air to enter the cabinet while still providing security. Removable roof vent panels enable quick installation of chimneys or fan systems. Best-in-class cabinets have built-in fans.
Accessibility
Enclosed cabinets can make it difficult to access equipment if they’re not properly designed. Dual side panels and split rear doors make access quick and easy. Adjustable mounting rails further facilitate the installation and administration of IT equipment.
Power Consumption of a Server Rack
As data center density increases, server racks are supporting more power than in the past. Not that long ago, the typical cabinet used about 3kW to 5kW of electricity. Today, the power consumption of a server rack is about 10kW on average, depending upon the capacity of the power distribution circuits. In a high-density environment, it’s important to have the right PDUs to support the equipment and power load. High-quality server racks allow for the mounting of vertical PDUs in the back of the cabinet to maximize available space for network gear.
Cable Management in Server Racks
Best-in-class cabinets support both vertical and horizontal cable management solutions. Vertical cable managers mount in the back of the server rack, while horizontal solutions fit standard 19-inch cabinet widths. Proper management ensures that cables don’t impede airflow or access to equipment. It also protects cables from excessive bending or crimping and makes it easier to identify what cables go where.
RF Shielded Server Racks
Data centers requiring high security and privacy levels may require server racks with RF shielding to prevent eavesdropping. RF shielded racks are also used in testing labs to enable dense installation of wireless devices while eliminating RF interference.
