HP ProLiant BL660c Innovative technologies in HP ProLiant Gen8 servers - Page 6

HP Advanced Memory Error Detection Technology seeks out specific defects that either cause performance degradation or significantly increase the probability of an uncorrectable (nonrecoverable) memory condition. By improving the prediction of non-recoverable memory events, this technology prevents unnecessary DIMM replacements and increases server uptime.

Power efficiency For ProLiant Gen8 servers, we developed HP Common Slot Platinum Plus and 750 W Common Slot -48VDC Power Supplies. These are the most efficient server power supplies in the industry. We also added internal thermal sensors-HP Sea of Sensors 3D-to selected PCI Express option cards. HP Common Slot Platinum Plus Power Supplies HP Common Slot (CS) Platinum Plus Power Supplies have 94% efficiency at 50% utilization, meeting 80 PLUS specifications for Platinum certification. In addition, our engineers increased power factor at lower utilization levels and made improvements to minimize total harmonic distortion (THD). CS Platinum Plus Power Supplies also support HP Power Discovery Services (Intelligent Power Discovery technology) to eliminate certain power distribution problems and wiring errors. 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 HP CS Platinum Plus Power Supplies have a flatter efficiency curve than previous generation power supplies. We achieved this by improving power efficiency at lower server utilization (load) levels. We also improved the power factor to reduce power-related operating costs. 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 datacenter 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.
