• • • • HPE Intelligent Power Discovery Services HPE Thermal Discovery Services
Intelligent Power Discovery Services combine an iPDU and CS Platinum/Platinum Plus Power Supplies with HPE software to create an automated, energy-aware network between IT systems and facilities. Intelligent Power Discovery Services with iPDUs automatically track power usage and document configurations to increase system uptime and reduce the risk of outages.
Intelligent Power Discovery provides automated server discovery on a network through power line communication technology that is embedded in CS Platinum Power Supplies. Power line communication is a feature that allows the power supply to communicate with the iPDU. The communication between the power supply and iPDU helps:
Automatically discover the server when it is plugged into a power source Map the server to the individual outlet on the iPDU
Thermal Discovery Services increase compute capacity by intelligently placing the workload where customers have the most power and cooling capacity. This feature helps businesses both reduce energy consumption and maximize usage of data center power and cooling capacity.

HPE iPDUs
Figure 4-16 HPE iPDUs The key element of Power Discovery Services is the iPDU, shown in Fig-ure 4-16, which is a power distribution unit with full remote outlet control, outlet-by-outlet power tracking, and automated documentation of power configuration. HPE iPDUs track outlet power usage at 99% accuracy, showing system-by-system power usage and available power. The iPDU records server ID• • • • • •
information by outlet and forwards this information to HPE Insight Control/HPE OneView, saving hours of manual spreadsheet data-entry time and eliminating human wiring and documentation errors.
When combined with the HPE line of Platinum-level high-efficiency power supplies, the iPDU actually communicates with the attached servers to collect asset information for the automatic mapping of the power topology inside a rack. This capability greatly reduces the risk of human errors that can cause power outages.
Using the popular core-and-stick architecture of the HPE modular PDU line, the iPDU monitors power consumption at the core, load segment, stick, and outlet level with unmatched precision and accuracy. Remote management is built into the PDU core for power cycle ability of individual outlets on the extension bars and high-precision monitoring of current, voltage, wattage, and power that is 99% accurate across the C19 outlets.
The iPDU can help users track and control power other PDUs cannot monitor. Information is gathered from all monitoring points at half-second intervals to ensure the highest precision. The iPDU can detect a new server even before it is powered on.
An iPDU is ideal for enterprise customers who want to speed power configuration, improve monitoring to reclaim stranded power, and extend data center life. An iPDU enables you to: Determine the exact power consumption for every component in the rack with less than 1% variation in accuracy Monitor and control outlets individually for the ultimate control of power distribution within the rack Save valuable space in the rack with dense rack-mountable form factors HPE iPDUs have a patented modular architecture that improves their flexibility. This building block concept consists of two main parts, the iPDU core unit and extension bars. The Intelligent PDUs ship with one core unit, the mountable LED display, and mounting hardware. The six-outlet core unit is zero-U or 1U rack mountable. The 12-outlet core unit is 2U rack-mountable. This architecture: Communicates with the attached servers to collect asset information for the automatic mapping of the power topology inside a rack Speeds implementation time Greatly reduces the risk of human errors that can cause power outages

HPE Metered PDUs
The HPE metered rack-mount PDUs provide both single- and three-phase monitored power, as well as full-rack power utility ranging from 8.3 kVA to 19.9 kVA. HPE Metered PDUs provide rack-level power monitoring over the network. With billing grade accuracy, these PDUs are well suited for data centers wanting to make the most of circuit capacity or for co-location facilities needing to precisely track power usage for billing purposes. The low-profile, single-piece design provides multiple mounting options and ease of access to rear devices for maintenance. They are designed for HPE racks but will also work in a large variety of third-party racks using standard button and keyhole mounting. They can be installed on either side of the rack with outlets facing the back of the rack for easy access and improved clearance. For greater power density, they can be installed side by side on both sides of the rack with the outlets facing in toward the center of the rack. Available metered PDUs include: Full-height (42U), mid-height (36U), and half-height (22U) vertical versions as well as horizontal (1U) versions Three-phase models with C19 receptacles Single-phase models with C13 and C19 receptaclesHPE Horizontal/Modular PDUs
HPE Horizontal/Modular PDUs have a unique modular architecture designed specifically for data center customers who want to maximize power distribution and space efficiencies in the rack.
Modular PDUs consist of two building blocks: the core unit and extension bars. The core unit can be mounted in either 1U or 0U locations and houses the output receptacles and circuit breakers for each load segment. Extension bars plug into the core unit, extending the outlet receptacles along the length of the rack. Extension bars reduce the need for long power cords and confusing clutter. They fit easily into the frame of the rack. Available models range from 16A to 48A current ratings, with output connections ranging from 2 to 32 outlets.
Benefits of HPE Modular PDUs include: Increased number of outlet receptacles Modular design

ProLiant Gen9 platform power architecture
Figure 4-18 Gen9 power supply compared to previous generationsThe ProLiant Gen9 power supply is 25% smaller by volume than the supplies of previous server generations, as shown in Figure 4-18. The large reduction in volume and 25% improvement in power density (from 40 W per inch to 50 W per inch) provide more server power in a smaller space. This large reduction in volume enables the HPE server design teams to add more internal devices:
1U platforms can add one PCI slot
2U platforms can add four SSDs (and potentially one more PCI slot)
HPE Flex Slot Power Supplies share a common electrical and physical design that allows for hot- plug, tool-less installation into ProLiant Gen9 servers. Flex Slot Power Supplies are rated for Platinum-level certification with efficiency of up to 94% and Titanium-level certification with efficiency of up to 96%. Support for Power Discovery Services, through embedded PLC technology, is available with the 800 W Titanium and 1400 W Platinum Plus models. This feature enables each server to communicate identification, location, and power-related data to the Intelligent PDU in the rack; this information can then be shared with HPE Insight Control/HPE OneView to manage power usage and efficiency in the data center.

supply options. Flex Slot Power Supplies are certified for high-efficiency operation and offer multiple power output options, allowing users to “right-size” a power supply for specific server configurations. They support both low-line and high-line AC input voltages providing additional flexibility to operate in multiple IT environments (500 W and 800 W Platinum only). Input voltages of –48VDC, 277VAC, and 380VDC are also available. This flexibility helps to reduce power waste, lower overall energy costs, and avoid “trapped” power capacity in the data center.
An HPE innovation, the HPE 750 W Flex Slot Battery Backup Module installs into a single Flex Slot Power Supply bay to free up the space needed for rack mount UPS without com-promising server uptime. Daisy-chained operation between two battery backup modules allows paralleled connection for pass-through power sharing between two ProLiant DL300 Gen9 series servers. In the event of a power outage, the module can provide up to 750 W of power for up to 60 seconds, or up to 500 W when in paralleled configuration.
