Modular Computer Server Room: Secure Data Center Rooms

How to Put Together a Safe and Reliable Computer Server Room

A server room is a necessary attachment for businesses (and some homes) to house vital technological equipment such as computer networking devices and data storage servers. They can range in size depending on needs, with some housing as few as ten computers and others equipping over one hundred.

As a server room (also referred to as computer server room) is specifically designed for storing technological equipment, it’s not shocking to hear that server rooms have very specific requirements. Without proper housing and equipment, the technology can be prone to fires, overheating, radiation, and more.

With so much to consider when putting together a server room, it can be somewhat overwhelming. Well, consider this article as your go-to server room guide. Below, you will find all of the necessary structural and equipment requirements to put together a reliable, and more importantly safe, computer server room.

Requirements for Properly Setting Up a Server Room

There are many specific requirements that must be included when creating a server room. Since the computer server room is specifically designed for housing technological equipment, the stakes are higher than putting together other “basic” rooms or structures.

Size and Placement of the Server Room

The first thing to consider is the size of your computer server room. While a small business server room may only need to be a few dozen square feet, a server room network that is used by multiple businesses may need to be several hundred square feet. The best thing to do is to calculate your needs and go from there. (Or calculate 50 to 100 kW per square foot).

Regardless of the size, location is also important. Ideally, server rooms should not share exterior walls. They should never be placed in basements or on top floors, either. This is due to the fact that there could be moisture, leaks, and other elements deposited from the connecting wall that could destroy the server room.

The server rooms should be free of windows and have enough space for proper organization and proper growth. Consider the ceiling, too. The ideal height is at least nine feet and should be a drop-style ceiling.

A few key pointers:

  • Make sure that all racks have a 42-inch or more clearance
  • Each rack should have proper grounding
  • Computer equipment should not exceed 300 watts per square foot of electrical intensity

It’s no secret – your server room needs power in order to operate. But the power must be reliable, and plugging computer equipment and data servers into utility power is not recommended (in case of a power outage, for example).

The better option is to use an Uninterruptible Power Supply, otherwise known as a UPS. The UPS is able to provide emergency power to your server room during the event of a sudden power outage. The UPS will be connected to a power distribution unit, which should be placed on one of the many server racks found in the server room.

Keep in mind that a UPS is only temporary, providing power for only a few short hours. It is not the cure-all for all types of power outages. For that reason, it is recommended to have multiple sources of power. A long-term option that can work conjointly with your UPS is an on-site generator.

Here are a few great ways to ensure the power will work reliably in your server rooms:

  • Computer equipment power panels should be separate from HVAC
  • No heat-generating equipment should be placed in server rooms
  • An isolated ground and dedicated neutral should be provided for all electrical systems
  • For emergency shutdowns, consider a shunt trip

Temperature and Humidity Control

Perhaps one of the biggest things to consider is climate control. With an excess amount of technology and power being surged into one building, maintaining an ideal server room temperature and humidity level is imperative.

The recommended temperature range for server room is between 68 and 71 degrees. This will ensure that moisture and heat are properly controlled. What about humidity? What is the recommended humidity level for server rooms? The levels should be between 40% and 60% at all times.

Since the abundance of computer and data equipment generates a lot of heat, having the ideal server room temperature and humidity level will keep overheating and fires at bay.

That said, a temperature-controlled server room is a must. You can maintain server room temperature requirements and humidity levels by doing the following:

  • Racks specifically designed for hot and cold configurations
  • Cooling equipment, such as fans with variable speeds
  • Under floor cooling system, which must be installed under a raised floor of at least 24 inches (raised floors can also be useful for cables, power outlets, and sensors, and can be useful in the event of an emergency)
  • Air conditioning unit
  • Adding a server room temperature monitor

Monitoring and Security

Protecting from overheating, fire, and radiation aren’t the only things to consider when creating your computer server room. You must also consider the possibility of burglaries and other security risks. Below are a few ways to ensure your server rooms remain safe and secured at all times.

  • Always keep the doors locked
  • Do not have a sign indicating the room is used as a server room
  • All entry options should be secured to be able to withstand break-ins
  • If there are windows, they should be secured with grids, locks, hatches, etc.
  • Equip accessible workers with badges or ID cards
  • Put together an authorization concept
  • Document all presence in the server room

Video surveillance is also a great method of monitoring your server room. Not only can this protect against break-ins, but it can indicate if there is overheating, fires, water damage, etc. Just make sure that it is a data protection-compliant recording structure.

Keep in mind that networks should be monitored at all times, too. A break-in doesn’t always have to be physical. There is the potential for hackers to “break in” to your network system, compromising important and vital documents and information that should not be shared.

Fire Suppression

Even though your data center might have the ideal average server room temperature and it is equipped to stop break-ins in their path, it doesn’t mean you’re entirely free from the biggest fear that comes with putting together a computer server room: fires.

Server rooms are incredibly vulnerable to fires. That said, you shouldn’t rely on temperatures and raised floors alone. A proper fire suppression system should be invested in to stop fires should they occur.

Fire suppression equipment will utilize gas or other chemicals to extinguish fires as they arise. To install, most suppression systems will require pressure relief venting. So, consider adding this to your initial structure setup before investing in a fire suppression system.

Don’t forget the importance of installing simple smoke alarms, too. This alarm will coincide with the other alarms installed in the server room, such as the humidity, water, and temperature monitor and security alarm.

How much space do you need for a server room?

The size of a server room depends mostly on how much data networking and computer systems you plan to house. A three-bedroom home will require a much smaller computer server room than a three-story building.

Although the size can fluctuate, there should always be room for potential growth. You may not need to increase the size to fit computers or other systems, but you may need to add additional cooling units in the future.

Make sure that the ceilings are at least nine feet high and the building is windowless. Doors should also be large enough to install bigger servers. The recommended size is 42 inches wide and 8 feet tall. They should be heavy and lockable for security purposes.

What is a computer server room?

This question is the same as asking, What is a server room or data center? They’re the same thing. The goal is to house computers, data networking systems, and other technological equipment safely and securely.

Do server rooms require fresh air?

No, server rooms do not require fresh air. They do require a temperature-controlled room, though. In fact, this is one of the most important elements of putting together a computer server room. Cooling units are necessary for deterring overheating and fires.

Where should a server room be located?

Ideally, a server room is its own building that is not connected to any exterior walls. This provides the safest spot for the equipment and those who work in the structure.

Final Words

Creating a computer server room can be a daunting task with plenty of requirements, but each requirement serves a specific purpose. The biggest thing to remember is that the computer server room needs perpetual access to power, even in the event of a power outage. It also needs to be temperature-controlled to reduce the risk of overheating and fires. Lastly, it should be secured and monitored at all times.
