The document discusses energy consumption and efficiency in data centers, highlighting the annual cost of powering a server rack and the importance of optimizing temperature for energy savings. It introduces the Powercast sensor system for wireless environmental monitoring, including various sensor configurations for tracking temperature, humidity, and other metrics. The system offers benefits like long battery life, flexibility, and compatibility with different networks to enhance monitoring and management capabilities in data centers.
Data Center Monitoring
- 1. Data Center Monitoring DCIM Green Data Center Energy Savings
- 2. Data Center Energy Statistics • Cost of over $50,000 annually to power a single rack of servers (Gartner Group) • Average total power to rack is about 4.05kW – 58% @ 5kW and less per rack – 28% @ 5kW to 10kW per rack – 14% @ 10kW or more per rack. • Typical 2011 PUE was between 1.83 and 1.92 • Each 1°F rise in temperature can reduce energy cost by 3-4%
- 3. Inefficient Operations… Excess running of fans (power, noise) Additional cooling (power, equipment) Significant waste of energy and money
- 4. Environmental Monitoring Contributes to Optimization Create temperature profiles for every rack Generate heat/humidity maps for multiple elevations Monitor for hot spots Identify air-flow obstructions Real-time insight and alarms
