1 Introduction Overview HP Insight Control power management (power management) is a component of HP Insight Control to work on Windows, HP Insight Control for Linux to work on Linux, HP-UX 11i v3 Base Operating Environment to work on HP-UX, OpenVMS Base Operating Environment to work on OpenVMS, and NonStop System Console companion DVD to work on NonStop J-series operating system.
2 Key concepts Data centers, racks, and power delivery devices Data centers HP Insight Control power management enables you to define the data center physical topology with racks containing systems, enclosures, and devices. A data center is an arbitrary rectangular grid that allows you to specify the placement of racks. You may create data centers to describe a lab floor or a portion of a computer room – that provides a useful grouping to summarize your environment and its power and thermal requirements.
Power delivery hierarchy Power is provided through a set of power delivery devices. Insight Control power management represents places that can be monitored in the power delivery points of the hierarchy such as PDU load segment output, PDU outlet, and so on, or a place where you may want to aggregate and report on power consumption of a set of devices like servers.
• Rack PDU: Rack Power Distribution Unit - This represents the input power and multiple outputs to load segments. • Load Segment: This represents each of the outputs of the PDU that can be monitored. HP PDU Management Module discovers up to the Load Segment level of the power topology. • Outlet Bar: This represents the division of the load segment into multiple outlets. • Outlet: A circuit with one input and one output that can be monitored. • Load: The power consumer connected to the outlet.
phaseWatts = phaseVoltage * phaseAmps TotalCapacity = 3 * phaseWatts For 1-phase: TotalCapacity = lineCurrent * lineVoltage Converting Watts to Amperes If you know the Watts value (watts), Voltage value (volts), and type of phase for the device, the watts can be converted to amperes using the following formulas: For 3-phase Wye or Delta: amps = (watts / volts) / sqrt(3) For 1-phase: amps = watts / volts Converting Amperes to Watts If you know the Amperes value (amps), Voltage value (volts), and type of ph
Security properties Protocols and ports numbers Insight Control power management uses the following ports or external interfaces to aid administrators in deployment and proper operation of the power management features: System/Device Protocol Default port number HP ProLiant and Integrity iLO SSL 443 HP c-Class Onboard Administrator SSL 443 Servers SSH 22 Integrity Servers WBEM HTTPS 5989 PDU/PDR SNMP 161 HP Intelligent PDU (iPDU) SSL 50443 Credentials Log-in credentials are presented to
• The Power Switch action is implemented with a mix of SSA tool invocations, as with Shutdown above; and calls to the Power State action, as described above. • The Run Script action runs scripts on the CMS as the Administrator/root user (that is, the user running the Systems Insight Manager CMS process). Power Regulator HP Power Regulator for ProLiant HP Power Regulator for ProLiant is a hardware feature that enables ProLiant servers to control performance states (p-states) of the system processors.
the maximum amount of resources, but it might affect the system performance if processor utilization stays at or above 75% utilization. • HP Static High Performance Mode. Power Regulator for Integrity sets the processors to the p-state with the highest performance and forces them to stay in that state. This mode ensures maximum performance, but it does not save any resources. This mode is useful for creating a baseline of power consumption data without Power Regulator for Integrity.
An idle system consumes the same power (339 W) regardless of the Power Regulator mode. Additionally, the power consumed in HP Dynamic Power Savings Mode matches the power consumed in HP Static Low Power Mode from idle to 80% utilization because this system is running in the lower processor p-state from idle to 80% utilization when it is in the Dynamic Mode.
new data center expansion can save your company thousands of dollars.
3 Managing power and cooling facilities in your data center Task: Importing power configuration from third-party management software HP Insight Control power management provides tools to read data from third-party management software in the form of SQL or web services queries. For each power management supported third-party management software, a command is provided to generate output in the text format suitable for use by the ipmimport command.
For a small data center, the data can be maintained manually in VIS format where a column in the Excel worksheet represents a rack and each cell is a slot position for a system. The VIS format is limited to only the physical hierarchy of the systems and devices in a data center. To convert data in the VIS format to text format, you can follow the instructions included in the ipmvis2txt man page.
you through the steps of configuring power management to provide you that holistic view, and help you understand and control your power and cooling requirements. Step 1: Identifying/Discovering your IT systems HP Systems Insight Manager provides a discovery mechanism to find all networked IT systems on your local network.
1. Specify the position of each system or enclosure in a rack. a. If you maintain a database (for example, UCMDB or Excel worksheet) describing the grouping of systems into racks and racks into a grid in a data center, you can import it directly into power management. For more information on importing information into power management, see Task: Importing power configuration from external databases. b.
In the Power/Thermal Analysis views page, • Power Status Alerts are highlighted with severity icons to highlight the severity of the alert. Alerts for contained devices are aggregated to the top-level object displayed. • Potential overloads are highlighted on the Physical Location tab for exceeded thermal limits and on the Power Delivery tab for power delivery devices.
or for the selected systems, you may wish to allocate a greater share of the cap headroom to production systems, and lesser cap headroom to test systems. Task: Getting notified of unexpected or excessive power consumption You can configure to receive notification if the power consumption of a system exceeds a specified limit. A limit is specified in terms of a power threshold (a number in watts), a duration (a multiple of five minutes), and a type which can be either average or peak power consumption.
based upon your current hardware configuration is significantly lesser than estimates based upon faceplate ratings, or even based on the HP Power Calculator. After describing segments of your data center in the Define Data Center page, you may have discovered additional capacity Step 4: Finding available capacity on power delivery devices .
While the faceplate power is 1000 Watts, the Calibrated Max Power as measured by the hardware itself is only 509 Watts, and based upon historical observation of several months, the highest power consumption ever observed was 432 Watts. Based on past behavior, there is 502-432 or 70 Watts that can potentially be reclaimed without noticeably impacting the performance of the system. When determining an appropriate cap to reclaim capacity, consider the following issues: 1. 2. 3. 4. 5.
Then, determine the amount of power must be reclaimed to make the necessary power/thermal capacity available in the rack. When applying caps, use the following guidelines: 1. 2. 3. 4. As the power demand varies, Enclosure Dynamic Power Capping can share caps between systems, it is the first place to investigate when capping and there is typically significant capacity that can be reclaimed by applying caps to enclosures.
Task: Defining rules for external events Data Center Power Control rules can be invoked manually or automatically using the mxexec command to respond to external events. To invoke a rule manually, use the mxexec command. For more information on mxexec command, see mxexec command in HP Systems Insight Manager Command Line Interface Reference Guide available at http://h18002.www1.hp.com/products/servers/management/hpsim/infolibrary.html.
