Energy costs continue to be a major area of concern when cooling a data center. With cooling comprising a significant portion of energy, special attention must be placed on capacities and efficiencies of cooling equipment to offset these costs. Find out more from this presentation given by CEO of DP Air Corp, Arnie W. Evdokimo.

Cooling a Data Center - DP Air

  1. 1. Cooling a Data Center:Increasing Efficiency to Cut Data Center Costs
  2. 2. Cooling a Data CenterCooling a data center requires careful analysis andproper design techniques. Climate-sensitiveenvironments such as data centers, computer rooms,medical facilities and telecommunications hubs,must be properly cooled to ensure ongoingoperation and equipment maintenance. Withoutestablishing and maintaining specific temperaturelevels, equipment will fail.
  3. 3. Cooling a Data CenterTo ensure continuous data center availability,optimization of the right components is necessary.Cooling a data center is not just about installing anair conditioning system. The project is much moreinvolved and must consider things like equipmentoptions, air flow dynamics, facility structure, floorconstruction, hot and cold aisle containment optionsand environmental factors.
  4. 4. Cooling a Data CenterThe appropriate design for cooling a datacenter should be based on a thoroughanalysis, company objectives and budgetconstraints. Numerous options exist forcomputer-grade environmental control. Thebest fit is dependent on the individualcircumstances of the company and its datacenter operations.
  5. 5. Cooling a Data CenterData center cooling systems come in various manufacturer packaged andnon-packaged systems. Typical systems installed include process cooling,humidity control systems, cooling towers, centralized pump stations,chillers and system monitoring and controls.However, cooling a data center doesn’t stop with a system installation.Just as important is the ongoing maintenance of the cooling equipment.Preventing failures is the key to systems availability and the costlyconsequences of downtime.
  6. 6. Cooling a Data Center How to Increase Cooling Efficiencies• Industry experts regularly talk about the rising cost of electricity and the increasing use of power consumption in the data center. For cost containment and green initiative purposes, company executives and data center managers are placing a premium on efficiency.• Data center cooling is a prime target for reducing energy costs. Some industry estimates place cooling consisting of approximately 37 percent of power usage. If the data center is not designed properly, that percentage, along with associated costs, can increase drastically.
  7. 7. Cooling a Data Center Data center operators and designers can adopt certain strategies to help control energy consumption related to cooling. Some of these strategies include the following:• Sealing the environment. Just like in a home, cool air escapes through vulnerabilities in floors, windows, doors, walls and ceilings. The same challenge exists in an data center. The facility must be properly sealed and protected from the outside environment to avoid cooling losses. Doors need to be kept closed as a starter when cooling a data center.• Then, data center designers and operators can create a “vapor seal.” This seal is a covering of materials such as plastic film, paint and vinyl used on walls, floors, doors and any facility opening. Moisture cannot be allowed to “migrate” to or from the data center environment.
  8. 8. Cooling a Data CenterPromoting Cooler Air Movement. Data center designers andoperators must make sure air flows efficiently throughout thefacility. Optimal air flow will go a long way in cooling a datacenter. Where components, such as racks, air conditionersand cables, are placed is an initial step.The basic concept in promoting air flow is to move as muchheat as possible away from equipment. The goal is toaccomplish this efficiently using the least amount of energy.
  9. 9. Cooling a Data CenterOne way data centers reduce energy usage is by using technology called“economizers.” During colder weather, the underlying concept is to bringoutside air inside for cooling a data center. This saves significant energyusage and costs.Another way to improve cooling efforts is to ensure the air conditioningequipment is operating for maximum efficiency. Technological advancescontinue to improve equipment operation. Improvements like variablecapacity and better controls optimize air conditioning equipmentoperation.
  10. 10. Cooling a Data CenterInstalling Supplemental Cooling Systems. To counter the effects of heatat its source, additional cooling systems can be installed nearby. Bycooling a data center at heat sources, less overall energy is required.This approach is especially useful for high rack densities. For example,equipment in the bottom rack consumes more cold air, leaving equipmentat the top sometimes insufficiently cooled. In fact, an Uptime Institutestudy found equipment located in the top third of a rack failed two-timesas much.
  11. 11. Cooling a Data CenterEnergy costs continue to be a major area of concern for data centerdesigners and operators. And, with cooling a data center comprising asignificant portion of these energy costs, special attention must be placedon capacities and efficiencies of cooling equipment to offset these costs.Plus, effective cooling strategies help keep equipment running andsystems available.
