HP ProLiant ML310e Innovative technologies in HP ProLiant Gen8 servers - Page 7

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 In previous-generation ProLiant 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 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 Our provisioning tools-Dynamic Power Capping and HP Enclosure Dynamic Power Capping- reduce the uncertainty in determining worst-case power requirements for servers. This helps administrators maximize data center power usage by fitting more IT equipment in the available power and cooling capacity. These tools are summarized below. For a more detailed description, read the technology brief ―HP Power Capping and HP Dynamic Power Capping for ProLiant servers.‖ Find it at http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01549455/c01549455.pdf. HP Dynamic Power Capping Dynamic Power Capping uses sophisticated monitoring and control circuitry to prevent server power from exceeding a preset level. Because Dynamic Power Capping is hardware-based, it can quickly control sudden surges in power consumption by servers and prevent tripping even the fastest circuit breakers used in HP Power Distribution Units (PDUs). You can set a power cap for an individual server from the iLO user interface. For groups of servers, you can set the power caps from the power management module within HP Insight Control. HP Enclosure Dynamic Power Capping We designed Enclosure Dynamic Power Capping technology specifically for BladeSystem enclosures. It lets you set a power cap for an HP BladeSystem Enclosure by using Insight Control (version 2.0 or later) or Onboard Administrator (firmware version 2.30 or later). The Onboard Administrator monitors and maintains the power cap for the entire enclosure by adjusting cap levels on individual server blades. As one server blade becomes busy and another becomes idle, Onboard Administrator adjusts the individual caps to give each server blade the power it needs while maintaining the total enclosure power draw below the cap. 7
