Airflow Management

Why should I manage airflow in my data center?

Airflow management solutions can help improve equipment reliability, increase cooling efficiency, and provide protection against downtime in your data center. Our airflow management products are cost-effective and energy efficient, allowing for reduced operating costs, as well as, impressive returns on investment.

How do I get started with airflow management?

Step: 1 Seal Openings: Start by sealing all floor and rack openings to reduce bypass airflow (air which is delivered into the data center and not consumed by the equipment and exhausted as waste heat). This will increase capacity, enable higher density, and dramatically lower energy consumption. We offer an entire range of grommets from raised floor to rack to aisle level.

Step 2: Direct Airflow: Next, utilize directional airflow panels to cool the same load as vertical plume panels with half the airflow. Delivering the right amount of airflow to the right place is a key component of an energy efficient data center.

Step 3: Control / Balance Load: Next, utilize either automatic or manual dampers which adjust cooling to match variable heat loads. All of our dampers significantly reduce bypass air and improves PUE. Tate Airflow Controls can be used in both retrofit and new build applications.

Step 4: Contain Airflow: Finally, contain cool air through use of doors, roofs, or cabinets to eliminate bypass airflow. We offer both virtual and physical aisle containment. Virtual containment has comparable cooling capacities to physical aisle containment, but does not require reconfiguration of fire suppression, lighting, or cause service disruptions associated with adding a roof like physical aisle containment.

Why should I seal openings in my raised floor and in my server racks?

Floor grommets and blanking panels are designed to virtually eliminate bypass airflow (air which is delivered into the data center and not consumed by the equipment and exhausted as waste heat), and increase capacity, enable higher equipment density, and help dramatically lower energy consumption.

What is directional airflow panels?

Directional airflow panels use patent pending technology to angle the air toward the equipment to achieve higher Capture Index ratings than standard airflow panels. This means that more airflow is delivered through the airflow panel that enters the face of the server rack, providing the higher cooling capacity and energy efficiency.

What is the advantage of directional airflow panels over standard perf panels?

Directional airflow panels deliver more airflow to the face of the server rack, providing the higher cooling capacity and energy efficiency over standard non-directional airflow perfs and grates.

Why should I use dampers with my airflow panels?

Dampers provide the ability to adjust and balance airflow by delivering the right amount of air to the equipment at the right time to maintain the proper inlet temperature. This means that system cools variable loads and partially deployed areas without wasting energy. Real time rack level monitoring and control of airflow improves decision making and reduces operating cost.

What is the advantage of automatic dampering systems over manual dampers?

Automatic dampers provide balancing by adjusting to variable loads and partially deployed areas without wasting energy. Real time rack level monitoring and control of airflow improves decision making and reduces operating cost. Key Performance characteristics
include:

  • Fail safe operation, opens 100% during failure
  • User programmable set point
  • Multiple zone damper positions
  • High Precision, Quick Response Temp Measurement
  • Viewable Peak Temp for walkthrough check of racks
  • Available Auto Transfer Switch offers N+1 reliability
What types of cabinets do you offer to better manage airflow?

Tate offers two types of cabinets. Tate’s IsoFlo cabinets completely isolate the IT cooling from the rest of the facility. Tate’s ContraFlo cabinets turn airflow upside down to offer an alternative to hot aisle containment or chimney designs. Using a raised floor plenum as the return plenum, ContraFlo can simplify the requirements needed to successfully isolate hot exhaust air. Automated airflow controls reduce energy costs and provide the most efficient use of the data centers IT cooling capacity. Cabinet level containment helps maximize the opportunity for air-side economization.

What types of containment do you offer?

We offer Tate’s ContainAire and Polargy’s PolarPlex Containment Systems. Our containment offering provides both modular based prefabricated systems, as well as custom deign and engineered systems. We offer a variety of doors, walls, and roof panels. ContAire and PolarPlex systems are easy to install and modify.

What is the difference between virtual and physical containment?

The difference between virtual containment and physical containment is that virtual containment does NOT require a roof to be effective. Virtual containment enables the data center to operate more efficiently by nearly eliminating wasted airflow while maintaining access and flexibility. Using a set of solutions to deliver the right amount of air when it’s needed directly to the equipment, virtual containment maximizes design. This is accomplished using directional airflow panels, control devices and doors at the end of the aisle to nearly eliminate bypass air, providing containment without the need for a roof or other overhead partitions.

Benefits of Virtual Containment

  • First cost savings over other containment strategies
  • Comparable cooling capacity to physical containment solution
  • No fire suppression, lighting, or service distribution concerns

Benefits of Physical Containment

  • Significantly reduces bypass airflow
  • Customizable products and sizes for any retrofit application
  • Can achieve 100% capture index at the server

Aisle Containment

Why should I consider containment for my data center?

Data Center aisle containment can improve capacity and energy efficiency by reducing bypass airflow. The separation of cold supply air from hot exhaust air is one of the most popular strategies in data center design. Our complete line of containment products can provide the best aisle containment configuration. We offer both prefabricated systems that are easy to install and modify, as well as customized containment solutions for both new construction and retrofit projects. All of our products offer valuable energy saving opportunities. Optimize your data center facility today by installing aisle containment.

What is cold aisle containment?

Cold Aisle Containment confines the cold supply air within the aisle so that it is only available to the equipment and cannot escape out the aisle ends or over the top of the aisle. The most common model of this containment approach is aisle end doors and roof panels on a raised floor with perimeter CRACs.

What is hot aisle containment?

Hot Aisle Containment focuses on isolating hot exhaust air on its return to the CRAC units or on its way out of the building. And this method of containment is clearly the trend for most new enterprise data center builds.

What is prefabricated containment?

Our prefabricated, flat-pack containment system is a smarter way to build because it installs in half the time of traditional stick-built systems and costs about a third less. Because containment is typically the final phase of data center construction, faster containment installation can mean finishing on time.

What is the advantage of utilizing modular infrastructure systems?

Modular white space infrastructure integrates containment, cable and power management, and lighting to speed and simplify deployment. Our partnership with Polargy is bringing “modular” to the white space.

Do you offer containment installation for new build and retrofit projects?

Yes, our informed, flexible designs, easy-to-install products, and experienced team of installers help assure schedules are met for both new construction and retrofit projects.

Data Center Cleaning

Why should I clean my data center?

Industry experts recognize that data centers should schedule regular preventive maintenance cleanings of their critical space by a qualified vendor. Regular and consistent data center cleaning can help prevent the significant cost of downtime, improve equipment reliability, help maintain an optimal environment for data center equipment, and is an industry recommended best practice.

According to the industry, how often should I clean my data center?

Cleaning frequencies are designed to provide an easy and clear standard for determining what services and frequencies are needed for your data center. Frequencies are based upon guidelines recommended by ASHRAE in their publication Particulate and Gaseous Contamination in Datacom Environments. Datacom equipment center cleanliness can be maintained by establishing a consistent cleaning schedule. Cleaning frequency should be increased during construction or other contamination-producing activities. The essential areas to clean and time intervals are described below:

Under Floor and Ceiling Plenums Minimum of once per year:

  • Remove large debris that cannot be vacuumed by hand.
  • Vacuum all accessible surfaces with a high efficiency particulate air (HEPA) filter vacuum
  • Vacuums motor should be shielded on all vacuums to prevent RFI and EFI interference with servers

Floor Surfaces: Minimum of once per quarter:

  • Damp-clean entire floor surface
  • Scrub floor surface as needed
  • Remove contamination beneath equipment racks and cabinets by brushing and HEPA vacuuming

NOTE: Most raised floor panels are covered with high-pressure laminate (HPL). This surface material is very durable but should not be abused. High-speed buffers should not be used. Low-speed scrubbers can be used. Water and non-corrosive cleaning solutions should be used sparingly and should be removed promptly from the surface. HPL flooring should never be waxed. Some, but not al HPL materials are conductive for electrostatic discharge (ESD) control. Coating this surface with standard floor finish may block the ESD path through the panel. Vinyl composition tile (VCT) floors should be periodically stripped and refinished with antistatic floor finish.

Equipment and Cabinet Exteriors: Minimum of once per quarter:

  • HEPA vacuum and/or damp-wipe surfaces with an anti-static cleaner.
  • Environment – Walls, Sills, Ledges, etc
According to the industry, what should I look for when choosing a data center cleaning vendor?

According to the Association of Data Center Cleaning Professionals, when selecting a data center cleaning vendor make sure that the vendor is experienced in cleaning data centers. An experienced data center cleaning vendor will meet the minimum standards set forth by organizations like ADCCP. The certification requirements of the ADCCP are designed to ensure that data center managers can trust that vendors meet certain minimum requirements to be considered a data center cleaning professional. Certification minimum requirements include expertise, experience, services, processes, training, equipment, chemicals, and insurance coverage to receive certification in our association.

Exterior Equipment Surface Cleaning: Exterior equipment surface cleaning includes cleaning the exterior surface of cabinets, equipment, and workstations by vacuuming where applicable with critical filtered vacuums, and then wiped clean an approved anti-static cleaner approved for use in data center environments. No input devices should be cleaned unless the device is completely powered down.

Interior Server Cabinet Cleaning: Interior server cabinet cleaning includes cleaning the surface of the server cabinet doors, server exhaust fans, and surfaces of the servers inside the cabinet. Surfaces are vacuumed with critical filtered vacuums and then wiped clean using an approved anti-static cleaner approved for use in data center environments.

Ceiling Cleaning: Ceiling cleaning includes overhead cleaning by either vacuuming above the drop ceiling tiles by using critical filter vacuums in compliance with recognized standards for cleaning data centers, and / or vacuuming and wiping clean overhead raceways with an approved anti-static cleaner approved for use in data center environments.

Anti-Static Floor Finishing: Anti-static floor finishing includes applying an approved anti-static floor finish to non-raised floor surfaces to prevent dangerous static build-up. Manufacturers of high pressure laminated (HPL) access floor panels strongly recommend never to apply floor wax to the surface of the access floor panels.

Subfloor Encapsulation: Subfloor encapsulation includes the application of an epoxy coating to the concrete subfloor plenum surface that acts as a vapor and dust barrier. Epoxy coatings should be applied manually to the surface of the subfloor plenum. Installing a Subfloor encapsulate is one of the best ways to reduce concrete dusting and subsequent airborne particulate concentrations in your data center.

Airborne Particulate Count Sampling: Airborne particle count sampling includes a sampling of airborne particulates within your data center utilizing a laser particle counter. Particulate sampling is an indicator of airborne contamination. We recommend that an airborne particle count sampling be obtained at each regularly scheduled maintenance cleaning by trained personnel.
