| + | There are two sources of power and most racks (other than HPCC) are tied into both. Emergency power that comes from the enterprise UPS (with bypass to utility power and backed by gas generator) and plain utility power delivered directly from the power grid. The UPS logs kwh consumed. The utility panels were clamped for a month and consumption logged. The HPCC racks were individually logged using an PDU with amp meter. Since the HPCC is a big variable much effort was spend to assess it's consumption, | ||

| + | The total cooling load for the data center space including load values above, and a potential for a 25% capacity increase is approximately – 94.5 kW. The 5 kW load associated with heat loss from the UPS is not factored into the data center cooing load and is planned to be handled separately. | ||

| + | It is recommended for the purpose of the study to use a total load of approximately 88kw, based | ||
| + | on the capacity of the proposed cooling units. That would account for enough capacity to handle | ||
| + | today' | ||
| + | cooling installed would also have the ability to be expandable if additional growth is required | ||
| + | beyond the 88 kW design limit. The breakdown of the proposed load is as follows: | ||
