Cold Aisle Containment

Cold aisle containment is a data center cooling strategy used to optimize the efficiency of cooling systems in server rooms and data centers. It is designed to create a controlled environment that separates the cold air supply from the hot air exhaust in order to improve cooling efficiency and reduce energy consumption.

Cold aisle containment is a best practice in data center design and management, as it helps improve energy efficiency, equipment reliability, and overall cooling system effectiveness. By separating the hot and cold air streams and directing cooling resources more efficiently, organizations can achieve cost savings while ensuring the reliable operation of their IT equipment

Hot Aisle Containment

Hot aisle containment is a data center cooling technique used to optimize the efficiency of cooling systems and reduce energy consumption in data centers. In a data center, servers and other IT equipment generate heat, and it's crucial to maintain the appropriate temperature to ensure the reliable operation of these devices. Hot aisle containment is one of the methods employed to achieve this goal.

In a data center, servers and other IT equipment generate heat, and it's crucial to maintain the appropriate temperature to ensure the reliable operation of these devices. Hot aisle containment is one of the methods employed to achieve this goal.

The Need for Aisle Containment

  • Energy Efficiency: Data centers are power-hungry facilities that require a significant amount of energy to operate, with a substantial portion of that energy used for cooling. Cold aisle containment reduces the amount of energy needed for cooling by ensuring that the cool air supplied to servers is contained within the cold aisle and not wasted in other parts of the data center. This results in lower energy consumption and cost savings.
  • Equipment Reliability: IT equipment, including servers and networking gear, has specific temperature and humidity requirements for optimal performance and longevity. Maintaining a consistent and cooler temperature within the cold aisle helps ensure that the equipment operates within these recommended parameters, reducing the risk of overheating and equipment failures.
  • Heat Management: Servers generate heat as they operate, and this heat needs to be efficiently removed to prevent equipment overheating. Cold aisle containment helps manage and control this heat by channeling it away from the IT equipment and into the hot aisle, where it can be more effectively extracted by cooling systems.
  • Hot/Cold Air Separation: Without containment, hot and cold air can mix within the data center, leading to inefficient cooling. This mixing, known as air recirculation, can cause hot spots and temperature variations, making it challenging to maintain consistent cooling throughout the data center. Cold aisle containment ensures a clear separation between the hot and cold air streams, preventing recirculation and temperature fluctuations.
  • Scalability: As data centers grow and evolve, it becomes increasingly important to have a scalable cooling solution. Cold aisle containment can be implemented in both new and existing data centers, making it a flexible and adaptable solution that can accommodate changing IT loads and configurations.
  • Environmental Impact: Energy efficiency is not only about cost savings but also about reducing the environmental impact of data center operations. By minimizing energy consumption for cooling, cold aisle containment contributes to sustainability efforts by reducing greenhouse gas emissions associated with data center operations.
  • Regulatory Compliance: Some regions and industries have specific regulations and guidelines related to energy efficiency and environmental responsibility. Cold aisle containment can help data centers meet these compliance requirements, avoiding potential fines or penalties.
  • Operational Cost Savings: Beyond energy savings, cold aisle containment can lead to operational cost savings by extending the lifespan of IT equipment (reducing replacement and maintenance costs) and reducing the need for costly infrastructure upgrades to accommodate growing IT loads

In summary, the need for aisle containment in data centers is driven by a combination of factors, including energy efficiency, equipment reliability, heat management, scalability, environmental considerations, regulatory compliance, and operational cost savings. It is a practical and cost-effective solution for improving the overall performance and sustainability of data center operations.

Our Aisle Containment Solutions

Hot Aisle Containment (HAC)

In a hot aisle containment setup, the hot air expelled from IT equipment is enclosed within a containment system, such as plastic curtains, doors, or panels, to prevent it from mixing with the cold air in the data center. This design reduces cooling requirements and promotes better temperature control.

Cold Aisle Containment (CAC)

In a cold aisle containment setup, the cold supply air is enclosed within a containment system, while the hot air from the equipment is allowed to mix freely within the data center space.

Raised Floor Airflow Management

Data centers utilize a raised floor system to manage airflow. Adjustable floor tiles and baffles can be used to direct cold air where it's needed most, ensuring efficient cooling.

Containment Curtains and Panels

Flexible containment solutions, such as PVC strip curtains or panels, which are fire retardant can be used to enclose aisles. They are cost-effective and easy to install but may not provide the same level of containment as rigid systems.

Metal Fuse Link

Metal fuse links are commonly used in fire protection systems. When the ambient temperature rises due to a fire, the metal fuse link melts, allowing the fire retardant PVC Strip Curtains used in Containment area in Data Center to drop down thus facilitating the fire extinguishing system to access the area covered for containment.

Modular Containment Solutions

Some companies offer modular containment solutions that can be customized to fit a data center's specific layout and requirements. These modular systems are often easier to install and reconfigure as needed.

Rack-Based Containment

With this approach, individual server racks are equipped with doors, panels, or other containment features to isolate the airflow within the racks. Rack-based containment is highly flexible and can be implemented incrementally.

Containment Doors

Containment doors can be installed at the ends of cold aisles or server rows to prevent the mixing of hot and cold air. They are often used in conjunction with other containment solutions.

? What is Airflow Containment?

Airflow Containment makes your data center more efficient by channeling your cold air to where it is needed and thereby reducing wasted energy. Airflow Containment also prolongs the life of your equipment by maintaining safe operating temperatures.

? Why should I get containment in my data center?

Containment is the most effective way to keep hot air and conditioned air separated. In a data center without containment, the hot air naturally rises towards the ceiling, creating air currents that mix hot and cold air compromising the efficiency of the cooling system. By isolating the hot and cold air through the use of containment, hot air is directed back to the cooling system and cool air to the servers. This enables higher set points units, eliminates hot spots, lower fan speeds, and can often eliminate the need for one or more CRAC units in larger data centers. In most cases, containment pays for itself in under three years.

? Is my data center efficient?

Chances are you’re wasting money!

Our specialized engineers can analyze and tell you if your data center is efficient and show you how to maximize your efficiency.

Up to 50% of a data center’s energy bill can be tied directly to providing cooling for IT equipment. It requires a great deal of resources to ensure your IT equipment is operating within suggested parameters.

It is estimated that 60% of the cool air supplied by CRAC air conditioning units never reaches the intended IT equipment through leaks or bypasses. In the past this problem has been addressed by over-cooling the entire IT environment and has resulted in wasted energy, unnecessary costs and lost data center capacity.

? Which is better, Hot Aisle or Cold Aisle Containment?

Hot aisle containment isolates the return air and directs it back to the cooling unit. The rest of the data center essentially functions as a 'cold aisle'. The primary advantage to Hot aisle containment is the warmest air is returned to the cooling unit, maximizing efficiency. The disadvantage is by isolating the hot air, there is a larger area to be cooled, slightly increasing cooling temperature requirements. Cold aisle containment traps and creates a pool of conditioned air by capping the top and ends of the aisle. The rest of the data center functions as a hot aisle. The primary advantage to cold aisle containment is the cool air is directed to the servers, minimizing the risk for hot-spots and reducing the space to be cooled. A disadvantage is a warmer working environment, and less efficiency in recycling air. Which option is best depends on several factors including size of the data center, obstructions, cooling hardware and design, etc..
