1 CUSTOMER Data Center Functional Testing [location] Data Center Prepared by: Leading Edge Design Group Prepared For: [CUSTOMER] [address] [address] [date]

2 [DATE] [CUSTOMER] [NAME] [ADDRESS] [ADDRESS] Project: [CUSTOMER] Data Center Functional Testing I. EXECUTIVE SUMMARY We are pleased to provide the enclosed Data Center Functional Testing Report associated with the new [CUSTOMER] data center in [LOCATION]. The objective of the functional testing initiative is to analyze the performance of the data center physical infrastructure to verify the equipment operates as expected and in consistent with design conditions. To perform this testing, active equipment was installed in the data center racks to simulate live IT load. II. METHODOLOGY Based on the data provided by [CUSTOMER] and [PROJECT STAKEHOLDER] the following field conditions were utilized as the basis of testing: 1. 3 (three) data center rows are installed in the new facility. Only Row 1 and 2 are expected to be populated with equipment on day 1 and functional testing was conducted on Row 1 and Row 2 only. 2. The basis of design for IT load per rack was 5.5kW per rack. 3. (model xxxxxx) is installed as the primary cooling methodology in the data center. The cooling has been designed with N+1 redundancy such that a single in row cooling unit can fail without compromising the environmental conditions in the data center. 4. [CUSTOMER] seeks to maintain inlet rack temperatures within ASHRAE Tc9.9 recommendations. The cooling setpoint (measured at the server inlet) established for the data center was 68degF. To administer the functional testing under these conditions, the following methodology was employed: 1. 1 (one) Microstar 17.1kW load bank was installed in each data center rack being tested. Load banks were factory tested for performance prior to arrival onsite (six) power cords for each load bank were installed and separated across the redundant 0U rack PDUs (rpdu) installed in each rack. 3 (three) power cords were connected to each 0U rpdu to simulate expected data center conditions and balance power across phases during testing. 3. During all testing, dry bulb temperature readings were gathered in 3 (three) locations across the vertical face of the rack to validate cooling system performance in all rack U positions. These temperature readings are represented on the enclosed reports as Temp F Top, Temp F Middle, and Temp F Bottom 86 Chosen Vale Lane Suite 201 Enfield, NH info@ledesigngroup.com ledesigngroup.com

3 4. All testing was completed in coordination with onsite APC field service technicians who were responsible for operating data center equipment. 5. A pass condition represents that the cooling equipment successfully maintained rack inlet temperature conditions within ASHRAE Tc9.9 conditions. III. FUNCTIONAL TESTS All functional testing was completed onsite by Leading Edge Design Group on [DATE]. The table below represents each of the 11 (eleven) functional tests performed. Please reference enclosed drawing T1.0 for further information on rack nomenclature utilized during testing and enclosed functional test reports for detailed information on each test. FUNCTIONAL TEST SUMMARY Row Test Test 1 Objective Status Number 1 1 Normal 5.5kW Validate performance under normal Pass cooling conditions 1 2 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test under failure condition at unit #1 1 3 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test under failure condition at unit #3 1 4 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test under failure condition at unit #5 1 5 Upper Limit 7.5kW Validate performance under expected Pass upper rack loading limit of 7.5kW Upper limit cooling Validate N+1 redundancy requirement Pass redundancy test at upper rack load limit under failure of cooling unit #4 2 1 Normal 5.5kW Validate performance under normal Pass cooling conditions 2 2 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test under failure condition at unit #1 2 3 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test under failure condition at unit #3 2 4 Normal load cooling Validate N+1 redundancy requirement Pass redundancy test 2 5 Upper limit cooling redundancy test 3 under failure condition at unit #5 Validate N+1 redundancy requirement at upper rack load limit under failure of cooling unit #4 1 It was noted that no blanking panels were installed onsite during the time of testing. It is recommended that these are installed to optimize cooling performance 2 7.5kW upper limit was defined onsite by customer 3 Cooling unit #4 failure simulation was conducted in Row 1. Measurements taken at server inlet during this condition were in Row 2. Pass

4 IV. SUMMARY Based on the basis of testing outlined in Section II and the data collected onsite by Leading Edge Design Group on [DATE], the cooling equipment in the [CUSTOMER] data center is functioning in a manner consistent with the design conditions and owner expectations. It was noted that under redundancy verification in upper limit testing (7.5kW per rack), some in row cooling units generated alarm conditions that the cooling set point of 68degF was unable to be maintained. Test data demonstrates that, although the set point could not be maintained, the server inlet temperatures in this test scenario were maintained within ASHRAE TC9.9 standards. Thank you for the opportunity to collaborate with you on your data center project needs. We are grateful for the chance to work with you and the entire team at [CUSTOMER].
