Six ways to lower costs through smarter cooling

Six ways to lower costs through smarter cooling

Cooling is one of the main drivers of data center operating costs, but figuring out how to get the information needed to drive costs down can be confounding.  Read on for ways to break the  overall challenge into manageable pieces as well as what you need from a monitoring system to support each approach.

Cooling System Performance
Changes in the performance of a cooling system may not be easily identified as they may happen gradually or be very location specific. Placing environmental monitors in strategic locations will identify changes in cooling system performance caused by equipment deterioration or failure as well as physical obstructions or changes to the data center layout.

Monitoring features to look for:

  • Flexible monitor placement -- floor, ceiling, by a door, beside your CRAH
  • Monitor portability -- move monitors to wherever you suspect problems
  • Easily scalable
  • Custom alerts based on your tolerance factors

Cooling Optimization
Many data centers operate at far cooler temperatures than required by customers or industry standards resulting in a substantial operating cost penalty. Rack inflow temperature monitoring can provide a baseline for cooling performance. As changes are made to contain and control airflow and gradually raise temperatures, monitors can track performance at the desired level of detail. The resulting 5-25% cost savings can deliver a payback within a year.

Monitoring features to look for:

  • Flexible monitor placement -- within and between racks, end of aisles, wherever you are considering adjustments
  • Multi-point monitoring
  • Easily scalable
  • Real-time reporting to monitor effects of changes made
  • Custom notifications and alerts based on your performance targets

Performance Improvement Validation
Capital investments typically require documentation of the subsequent benefits. A few strategically placed environmental monitors can report on the before and after conditions of a VFD retrofit or new containment system. Monitoring can justify past investments as well as help make the case for additional improvements.

Monitoring features to look for:

  • Flexible monitor placement -- within and between racks, end of aisles, wherever you plan to make changes
  • Multi-point monitoring
  • Reporting over time at the desired level of granularity down to the minute to monitor effects of changes made
  • Flexible reporting for facility operations, Finance and senior management

CRAH Efficiency
Environmental monitoring encompasses tracking differential pressure and humidity as well as temperature. Adding differential pressure and humidity sensors in strategic areas on the CRAH and plenums provides detailed performance and can help identify optimal settings. 

Monitoring features to look for:

  • Differential pressure and temperature sensors available
  • Flexible monitor placement
  • Custom reporting to ensure efficient equipment operation

Service Level Agreement (SLA) Compliance
Colocation providers often have agreements with customers to maintain specific environmental conditions. This typically consists of rack level temperature monitoring with the corresponding documentation to show compliance. 

Monitoring features to look for:

  • Multi-point monitoring within a rack and between racks
  • Easily scalable
  • Immediate logging and alerts
  • Segregated customer reporting

Facility Performance Benchmarking
Cooling systems can be influenced by changes in the data center and equipment performance. These can be subtle changes that are hard to track. A basic environmental monitoring system provides all the data needed to benchmark temperature, airflow distribution and energy usage over time.

Monitoring features to look for:

  • Low cost, quick and easy to install
  • Flexible monitor placement
  • Custom reporting that tracks conditions over time spanning days, weeks and months

If you're convinced of the need to monitor environmental conditions, you might be thinking that managing cooling performance is expensive and complex. But it doesn't have to be.  Packet Power's wireless environmental monitoring solutions check all the key features noted above and our monitors can be deployed and maintained at a fraction of the cost and time of competing systems.
