Hot Aisle Cold Aisle Containment

Hot Aisle / Cold Aisle Containment System for Efficient Data Center Cooling

It is an established fact that most legacy data centers waste over 60 percent of their cooling energy.  This is precisely why we specialize in efficient server cabinet cooling, and can help customers large and small significantly reduce server rack cooling expenses, through strategies that cost only a fraction of the energy they save.

Hot Aisle / Cold Aisle Separation and Containment

Hot aisle / Cold aisle containment is a key cooling cost reduction method.   It involves arranging the server racks and the IT equipment so that all heat is exhaust into hot aisles, and all air intakes draw from cool aisles. Cool air is supplied only into the cold aisle, with return air being drawn directly from the hot aisle.

Curtain Walls for  Hot / Cold Air Containment

 

Cold Aisle Containment Doors

Curtain Walls to block and contain
 hot air in the hot aisle and
 cold air in the cold aisle

 

Cold aisle doors, at both ends,
separate the cold air
 from the rest of the data center.

Hot aisle & Cold aisle containment not only increases energy efficiency but also allows the IT equipment populating the server racks to operate at ASHRAE TC 9.9 guidelines, which improves equipment functionality as well as  uptime. 

Common Methods for Hot Aisle / Cold Aisle Containment

Seismic  Rack Cabinets Prepared for Hot Aisle / Cold Aisle Containment

This group of seismic cabinets, at the assembly stage, will receive in-row cooling features such as sealing of the rack mount rails, installing plastic tool-free filler panels and air plenum / baffle systems. These specific  air plenum baffle systems are designed for the Juniper MX480 router and the Cisco ASR903 & 2951 routers.

 Separation of HOT AISLES from COLD AISLES can be achieved by:

  • Rigid Enclosures
  • Hard Panel Boards
  • Blanking Panels For Unused  Rack Positions
  • End Of Row Doors
  • Flexible Strip / PVC Curtains
  • Aisle Ceilings
  • Overhead Vertical Wall Systems
  • Snapin Modules
  • Aisle Ducts

Specially designed Mounting Channels are used by our engineers to affix vertical wall, strips, panels etc .to the server rack cabinet body, as well as surrounding walls.

 

Hot Aisle Containment & Airflow Plenums for Cisco Routers – By Gaw Technology

Our approach begins with a sealed separation between the hot aisle and the cold aisle , separation  accomplished at the front rail level.  In this application, the airflow management effort involved a wide series of Cisco routers: Cisco 7613, 2821, 3560E, 3845, 2911, 6509E, 4507R, 4510R, 4510E, and 4900M.  Since the routers were designed to intake cold air from the side, which is left by our separation in the hot isle, we utilized our proprietary CAAP (Cold Air Access Plenum) system, mounted under the routers and connected the cold air aisle through a duct to the intake on the side of the routers.

The hot aisle / cold aisle containment, coupled with the use of our proprietary CAAP system always  results in huge energy savings.   Let us design a cost saving solution for you.  Email or call us today: 1-877-429-7225

How to prepare a server rack cabinet for hot-aisle cold-aisle separation with Cisco 4507R and  Cisco 2911

The image shows how we prepare a server rack cabinet for a hot-air/ cold-air aisle separation. The spaces between the rails and the cabinet side and the rack mount rails are sealed. The top and bottom of the cabinet have blanking panels to seal those locations.

Also, tool-free plastic filler panels are used to fill in the rack mount areas not yet loaded with equipment. On this particular set-up there also are a variety of air plenums / air baffles systems to accommodate the Cisco router 4507R and the Cisco router 2911


Airflow Management

We offer couple of options for Cooling and Airflow Management. Our Server Rack Cabinets have Superior Heat Dissipation for all your electronic equipment. Please see below some of the solutions and contact us for a Quick Quote, more info and to buy server rack cabinets: 

Rack Containment 

Contain the heat and extract it directly back to the CRAC with our patented Heat Containment System (HCS) and use airflow managers, for switches and network devices, as well as blanking panels to ensure an effective rack hygiene methodology. 

  • Heat Containment System (HCS) - The Eaton Heat Containment System® (HCS) is a simple, scalable and low cost solution to more effectively manage the ever-increasing heat loads in today’s data center. 
  • Airflow Solutions for Switches and Network Devices - Eaton offers several solutions for devices with (non) front-to-rear airflow architecture. 
  • Blanking Panels - Blanking panels provide a quick, easy and cost-effective solution to optimize air circulation within an enclosure while maintaining high aesthetics. 
  • HCS Active Airflow Manager - Eaton's HCS Active Airflow Manager measures pressure differentials and temperature to regulate fan operation in active systems. 

Aisle Containment 

Our aisle containment solutions include a variety of Aisle Ceilings and overhead vertical wall systems, Aisle Ducts and End of Row Doors that allow you to alleviate the oversupply of cool air in the data center and increase individual rack capacity as well as CRAC cooling efficiency. 

  • Aisle Containment Ceiling/Walls - The Aisle Containment Ceilings and walls, used in conjunction with End of Row Doors, creates an efficient and predictable aisle containment solution. 
  • End of Row Doors - End of Row Doors, available in single-swing, café-style and sliding options, create more efficient contained aisles by blocking obvious escape routes for air and eliminating air re-circulation and air mixing. 
  • Independent Containment - The culmination of Eaton's containment strategies is its patent-pending Independent Containment System (ICS), a free-standing, scalable, sustainable and vendor-neutral containment solution for high-density computing environments. 

In-row Cooling

Room Containment 

Going beyond the rack and row you can implement room-based airflow management solutions to further enhance the efficiency and predictability of your data center. Our CRAC Collars and raised floor grommets provide an additional measure against bypass airflow. 

  • CRAC Collars - The CRAC Collar for downflow systems, used in conjunction with data center containment strategies is integral to Eaton’s total containment solution. 
  • Raised Floor Grommet - Eaton's raised floor grommet is comprised of non-permeable material that allows maximum pressure to be maintained in the sub-floor plenum by allowing cables to enter enclosures while minimizing bypass airflow.
