We had a customer who wanted us to do thermal and power testing around a compute solution. The Proof of Concept (POC) was set up to verify or validate power and thermal readings for the Cisco Unified Computing System (UCS) components (specifically the 5108 chassis, 2408 IO Modules, and 6454 Fabric Interconnects) of the FlashStack design.  

Our customer wanted to know what the power consumption looks like on a Cisco UCS 5108 chassis when it is fully loaded with B200 M5 blade servers.  Additionally, what happens when there are different load capacities happening? They also needed to understand the thermal capacity of the gear in the rack which would help them with a physical design.  Based upon power consumption and thermal readings, they were able to understand how many they could squeeze into a rack, which leads to how many racks in a row, and finally the capacity of the solution in their full data center design.  If you would like to see how we provided the testing for this, please read the ATC Insight section.
