Disable or remove existing water-based fire suppression systems within any <br />areas that will contain data center hardware and equipment. <br />Install wet and dry fire -retardant systems, including pre -action wet systems if <br />necessary. A dual -alarmed dry -pipe fire suppression system such as TotalPac <br />that is multi -zone and pre -action to ensure contained suppression is <br />recommended5. <br />Install a Very Early Smoke Detection Apparatus (VESDA) smoke detection <br />system or similar. <br />Power, and therefore cooling, requirements are much higher for a data center <br />environment than for typical occupancy (i.e. cabinet full of heat -producing servers <br />/ switches vs. human load). Provide a full study based on the quantity of service <br />loads. <br />Coordinate with the design center design team to provide for more specialized <br />infrastructure such as Power Distribution Units (PDU) as needed. <br />Install cooling / exhaust equipment upgrades to meet code requirements and <br />gain certification. <br />Provide upgrades for diesel generators, UPS units, and HVAC units to meet code <br />requirements. <br />Reconfigure existing facility equipment / infrastructure to meet current code <br />requirements. Design cost should include power / data wiring, as well as cooling / <br />ventilation in the overall design concept. Accommodations most likely would not <br />be possible with current cell configuration, which would require modifications. <br />Mechanical and Cooling <br />- Ensure adequate power / cooling redundancy requirements are met by replacing <br />or retrofitting existing heating and cooling equipment. <br />- Install all necessary filters to ensure very high resilience that meets failover <br />requirements. <br />- Manage data center cooling with a system such as the Liebert N+1 cooling <br />systems that can provide more than 370 tons of cooling capacity5. <br />- Maintain diligent maintenance standards to ensure equipment operates <br />successfully. <br />- Install cabinets in hot and cold aisle configurations so hot exhaust and cold <br />intake air are isolated from one another. Hot and cold aisle delivery should be <br />designed for maximum efficiency so IT hardware will function at its best. <br />- Ensure adequate power / cooling redundancy requirements are met by replacing <br />or retrofitting existing equipment. <br />Utilities and Power <br />Several fundamental principles should serve as the foundation for the electrical <br />system design. These include the provision of maintenance and emergency shut- <br />down switches at all entry points in the facility, as well as a grounding system that <br />complies with the National Electrical Code (NEC) or local codes if applicable. It is <br />important to note that existing facilities converted to data centers typically do not <br />provide the adequate electrical power -plant and distribution systems that are crucial <br />design criterion for a center's reliability and operational efficiency requirements. <br />120 <br />65A-127 <br />
