6. 10/30/2014Cummins Confidential6 Top Five Considerations for Specifying Data Center Power Systems Achieving the five nines……………………99,999% uptime 1. Ensure Redundancy, Avoid Duplicity (pre fuel filters vs. oil/coolant filters) 2. Seek Long Term Reliability to Maximize Uptime (selection of proven, tested and reliable equipment procured within an integrated system) 3. Limit Vendor Sources for Ease of Installation (Single Vendor w.r.t installation, trouble shooting and integration) 4. Select a Vendor with a Proven Installation/Service Record (available access to reliable services and accurate diagnostics) 5. Deploy a Focused Product Portfolio (understand equipment capabilities vs. non linear/linear load portfolio’s)
