Introduction In this technology brief, we describe a broad range of HP products and technologies that raise energy efficiency, maximize use of the power capacity, and simplify management of your data center’s power and cooling infrastructure. We begin in the ―IT processing‖ section by describing the technologies and tools that help you measure, monitor, and control the power usage of HP ProLiant servers to get the maximum performance per watt.

consuming less energy. The ability to use Common Slot Power Supplies across multiple platforms simplifies maintenance and reduces inventory. All HP Common Slot AC Power Supplies meet 80 PLUS® Silver, Gold, or Platinum specifications. The AC power supplies work with input voltages from 100 to 240 V, making them functional worldwide. Administrators can use the HP Power Advisor utility at http://h18004.www1.hp.com/products/solutions/power/index.

HP Dynamic Power Capping We use HP Dynamic Power Capping technology in most of the enterprise-class G5 ProLiant servers and beyond. 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 use from servers and prevent tripping even the fastest circuit breakers used in HP PDUs.

Discover the power distribution topology Our IPD solution works with ProLiant servers with iLO 2 (firmware v2.0 or newer) or iLO 3 (firmware v1.05 or newer).

management GUI and Insight Control include a Power Cycle Control switch that lets you cycle power simultaneously to the redundant outlets for each server. The switch works similarly for a manually entered device, such as a third-party device, for which the device’s universally unique identifier (UUID) is properly matched to its outlets.

Figure 2: Conventional AC power distribution using an online double conversion UPS Newer data centers may have more efficient power distribution systems, but there is still room for improvement. We based the design of the HP eco-mode UPS and HP Rack-mountable UPS on the basic principles we cited earlier to reduce power losses. They enable a power distribution chain that is 84% to 86% efficient, an improvement of about 10 percentage points over conventional distribution infrastructures.

racks below about 10 kW. Today’s high-density IT racks can generate significantly more heat, creating hot spots that need supplemental cooling or specific air channeling. Letting the entire facility run colder to compensate for hot spots is not a cost-effective option. The increasing heat loads require carefully planned cooling strategies such as hot-air containment and closed-loop cooling.

circulated (Figure 4). For more information, see the HP Modular Cooling System G2 Rack Overview at http://h10010.www1.hp.com/wwpc/us/en/sm/WF05a/3447589-3447589-34462853446371-3461917-3657806.html. Figure 4: Airflow in the HP Modular Cooling System G2 Data center power management with HP Insight Control HP Insight Control is a suite of licensed management software components that build on and complement HP SIM, which is included on all ProLiant servers.

Insight Control can discover and communicate with iPDUs to retrieve the power topology (see ―Discover the power distribution topology‖ above) and retrieve power measurement data. With HP iPDU technology, Insight Control knows which servers are connected to each iPDU. So when you drag and drop the iPDU to the rack on the Power/Layout, all the attached servers follow. You can repeat this procedure to create a model of each rack in the data center.

Figure 6: Power consumption graph in Insight Control showing the and average and peak observed power consumption and the power cap for a rack of servers. Power monitoring As we mentioned earlier, potentially overloaded circuits can lead to unscheduled downtime. The power monitoring capabilities of Insight Control let you accurately measure power use so you can manage it better.

generalized practices. The difference between the Calibrated Max Power and Peak Observed Power represents the potential power capacity that you can reclaim by applying the power cap value. The green range between the circuit Capacity and the Power Cap represents available circuit capacity. Figure 7: Power meter summary for a server Insight Control lets you identify potential electrical overloads at the PDU, rack, and data center level.
PAGE 13
Before Insight Control can generate the temperature profile, you need to describe the physical positions of your systems and racks. You can do this by importing a database (UCMDB or Microsoft® Excel worksheet), using enclosure information from HP BladeSystem Onboard Administrator, or by manually defining rack groups. Then you can view the peak observed temperature in each area of your data center over 24 hours through the Power/Thermal Analysis views page (Figure 9).
PAGE 14
At the rack level, the Power/Layout tab displays a specific rack configuration with power distribution devices, enclosures, and servers. The view in Figure 10 shows the rack height and the power distribution connections on Side A and Side B. The color of the enclosures and systems in a rack represents the thermal status of the particular enclosure or system as referenced by the temperature legend at the bottom of the screen. The monitored temperature range is from 59°F (15°C) to 86°F (30°C).

new devices. Insight Control also polls the iPDUs daily and updates the rack configuration if a server is moved or a new server is plugged into an iPDU. If you need a place to deploy a new server, Insight Control can identify the rack(s) with available power where you can put it (Figure 11). You simply click on the Available Power tab to determine where you have enough power for the server or device you need to deploy.

HP POD 40c and 20c The POD 40c is 40 feet (12 m) long with 1100U of rack capacity and twenty-two 50U 19-inch (482 mm) deep racks (Figure 12). It offers capacity equivalent to a 5,000 ft2 (464 m2) traditional data center. It provides up to 600 kW of non-redundant capacity or 380 kW of fully redundant capacity. Facilities personnel can connect it directly into 480 V utility power and the chilled water system. The POD 20c is 20 feet (6 m) long with 500U of rack capacity in ten 50U 19-inch (482 mm) deep racks.
PAGE 17
As a result, the HP POD 40c and 20c can have a PUE ratio as low as 1.25 depending on the configuration of the IT equipment and the water-cooling facility to which they connect. We can ship the HP POD 40c or 20c in as little as 6 weeks. For more information, visit http://h18000.www1.hp.com/products/servers/solutions/datacentersolutions/pod/index.html. HP POD 240a The HP POD 240a (nicknamed EcoPOD) is engineered for the ultra-high efficiency that is possible only with free-air cooling.
PAGE 18
We can ship the HP POD 240a in as little as 12 weeks. For more information on the EcoPOD, visit http://h17007.www1.hp.com/us/en/whatsnew/june/060611-3.aspx. Conclusion This paper has described the products and technologies we have developed around our three data center strategies: consume less power, fit more IT equipment, and work smarter.
