Multiple power-capacity options Having a CS form factor with multiple power capacity options (460 W, 750 W, and 1200 W) allows Platinum Plus Power Supplies to fit a wide range of HP server, storage, and infrastructure products. It also lets you right-size power supplies for multiple equipment configurations so you can use more of your data center's available power capacity. Improved efficiency and power factor Due to a design that optimizes the power factor, HP CS Platinum Plus Power Supplies achieve high efficiency at relatively low power utilization, and maintain that efficiency through the demand curve. This provides a consistent expectation of efficiency that is not dependent on utilization. Minimized Total Harmonic Distortion As data centers deploy more servers, power supply harmonic currents can potentially limit the maximum attainable utilization. HP engineers designed Platinum Plus Power Supplies to minimize THD across all load conditions to maximize data center utilization. HP Power Discovery Services Platinum Plus Power Supplies feature blue connectors that enable HP Power Discovery Services, which includes HP Intelligent Power Discovery (IPD) technology. IPD uses an embedded serial communication link to automatically discover newly deployed HP servers, map their power cords to the power source, verify power redundancy, and help ensure that all power sources are connected correctly.

HP -48VDC Common Slot Power Supplies The telecommunications industry has long used -48 V DC power distribution. Previous-generation HP 1200 W -48V CS Power Supplies operate at 90% efficiency. The latest HP CS 750 W -48VDC Power Supply for ProLiant Gen8 servers operates at 94% efficiency. It also has better power input cabling options and is compatible with a wider range of HP ProLiant servers. For a list of compatible servers, visit www.hpproliantoptions.com. HP Sea of Sensors 3D Introduced with ProLiant G6 servers, HP Sea of Sensors provides the data to precisely control the server fans and directly cool specific components, while not overcooling other components. This can reduce fan power consumption up to dozens of watts per server. HP Sea of Sensors 3D in ProLiant Gen8 servers extends the use of sensors to select PCI Express option cards, FlexibleNetwork Adapters, and FlexFabric Adapters to get a three-dimensional temperature profile in the server. This additional data enables more precise and efficient cooling of ProLiant Gen8 servers. The data is included in the always-on diagnostic information of the HP Active Health System. Power provisioning tools HP power provisioning tools include Dynamic Power Capping, HP Enclosure Dynamic Power Capping, and the HP Power Advisor utility. These tools, summarized below, help administrators maximize data center power usage by fitting more IT equipment in the available power and cooling capacity.
