5 Things To Keep In Mind When Buying A Server Cabinet

September 28, 2015

A server cabinet is one of the most overlooked components of data centre design – yet it houses the mission-critical information that your business depends on. The right server cabinet will not only effectively power, cool and protect your hardware – it will decrease downtime and increase the efficiency of your server room too.


A server cabinet isn’t a server cabinet isn’t a server cabinet…


Not all server cabinets are created equal, so we’re going to give you a few pointers to help you make the right choice when it comes to buying this vital piece of IT infrastructure.

1. Size

Make sure your server cabinet is large enough to house your current equipment and any future hardware you may need. 19 inch racks are the industry standard and are large enough to house the components for almost any network infrastructure.

Tip: When setting up your server cabinet, place heavier equipment at the bottom to reduce strain and keep hardware that you frequently use or remove at the front for easy accessibility. 

2. Security

Buy a server cabinet with locking front and rear doors. If security is really an issue, then environmental monitoring software may be the answer. This software allows administrators to monitor amperage draw per circuit, water leaks, temperature and even alerts them if the server cabinet door is open.

Tip: If you’re building a new data centre, try and build it away from a main road, limit the number of windows and have 1 secure entrance/exit to keep your IT infrastructure safe.


3. Design


You can set up your server cabinet to suit your needs with customisable shelving, top and side panels, mounting rails and feet.

4. Power

Power Distribution Units (PDUs) for your server cabinet come in two varieties: standard or intelligent. Standard units provide basic information to the administrator on-site. Intelligent units allow administrators to perform a cold reboot and troubleshoot problems from any location via the internet. Even though they are more expensive than standard units, they make use of 3-phase power which uses significantly less electricity and will save you in the long run.

Tip: Keep the number of outlets you will need and plug and redundancy requirements in mind.


5. Cooling


Choosing the right server cabinet will have a marked effect on data centre airflow.  Fully perforated racks allow for maximum airflow in ambient air cooling environments (fans or Computer Room Air Conditioning (CRAC) units) and fully sealed racks are best if you’re using liquid cooling or rack air conditioners.

Tip: Use blanking panels to manage air flow efficiency, choose a rack with built-in channels for better cable management and improved air flow and remove any obsolete or unnecessary equipment from the rack.
