A large part of understanding what needs to be done lies in understanding the current state of the data center. To control power and cooling costs and maximize utilization, we must be able to measure and report on this data, trended over time.
Monitoring is becoming increasingly inexpensive and granular. Examples include:
• The use of metering, or intelligent, power distribution units that can give visibility down to the port level.
• Cooling systems that can track and report on their own activity.
• Servers that report on internal chassis temperature.
• The use of a sensor grid to track temperature and humidity throughout the facility.
As with any endeavor, there must be agreement on what to track, how ...
