hp ProLiant DL320 generation 2 server high-density deployment technical white paper 4 Table 1 demonstrates how significant reduction in input current and thermal dissipation can be realized, if a deployment plan can limit each server configuration over the useful lifetime of a rack configuration. Table 1. Derated Current and Thermal Dissipation for Reduced Input Power Assumptions Input Power Input Current at 110 VAC Input Current at 208 VAC Thermal Dissipation 120 W 1.09 A 0.57 A 409 BTUs/hour Derated 250 W 2.27 A 1.20 A 852 BTUs/hour Fully Rated 277 W 2.52 A 1.33A 944 BTUs/hour The derated input power values of 120 W and 250 W can be correlated with the measured input power values for the minimum and maximum configurations of the server. However, the derated input power value must be high enough to account for any future upgrades for a deployment plan. As stated earlier, the power supply is designed to support future processor and hard drive upgrades. When installing 42 servers, the number of PDUs to be installed will depend on the support for the input current requirement. Carefully derating the input power may very well satisfy deployment needs and also reduce the number of PDUs per rack. Reducing the number of PDUs has a direct impact on the deployment time and maintenance of an installation.
