1 ITM 4.1: A Three-Step Approach to Better Instrumentation of the Data Center and Use of KPIs in Decision Making George Clement

2 Data Center World – Certified Vendor Neutral Each presenter is required to certify that their presentation will be vendor-neutral. As an attendee you have a right to enforce this policy of having no sales pitch within a session by alerting the speaker if you feel the session is not being presented in a vendor neutral fashion. If the issue continues to be a problem, please alert Data Center World staff after the session is complete.

3 A Three-Step Approach to Better Instrumentation of the Data Center and Use of KPIs in Decision Making This presentation will address the utilization of Key Performance Indicators (KPI) and the three-step process for acquiring readily available data from infrastructure and servers and how it can result in better decision making on asset management, capacity management, and data center performance. By following these steps, you can address an entire data center or trouble spot that needs attention.

14 Measurement Choices Temp Sensors on Servers Temp Sensors on PDUs External Sensors

15 More Sensors Are Better so use everything you can!!!

16 How to extract the data ? IT Devices Use Various Things: DCIM Applications Saves a lot of time if you have one – tell them to get you the real-time data SNMP C220 Cisco Server PDU / UPS IPMItool IPMItool sensor list OS dellservertemperaturehttps://community.spiceworks.com/scripts/show/1227-powershell-function-get- dellservertemperature hpasmcli -s "show temp"

17 Model Modeling requires that you focus on the averages and time windows. Decide on the detail you want to show Rack, Row,Room

18 Model Measure temperature at the various elevations of the rack by using sensors. Record the supply temperature from the cooling unit feeding that row Determine if there is more than a 5 degree Fahrenheit difference between cooling system set point and the warmest temperature at the rack, which means there is energy waste.
