Executive summary Executive summary This technical whitepaper provides recommendations on using Dell EMC OpenManage Enterprise Power Manager to effectively manage the power in a data center. The whitepaper provides insights into the usage of various features of Power Manager to conserve power and manage the data center in a more efficient way.
Introduction 1 Introduction Dell EMC OpenManage Enterprise Power Manager is an extension to Dell EMC OpenManage Enterprise (OME) console and uses fine-grained instrumentation to provide increased visibility over power consumption, anomalies, and utilization. Also, Power Manager alerts and reports on power and thermal events with servers, chassis, and groups consisting of servers and chassis. This enables increased control, faster response time, greater accuracy, and broader decision-making intelligence.
Monitoring and Capping Power in Data Center 2 Monitoring and Capping Power in Data Center This section focuses on using the metric data obtained for devices and groups to effectively optimize the power consumption in a data center. Various metrics such as power, temperature, utilization are collected at regular time intervals for devices and groups. View this historical data about the devices and groups on their respective pages or on the Reports section.
Monitoring and Capping Power in Data Center Historical Data for Group • Reports: After a duration of 7 days, run the reports from MonitorReports section of OpenManage Enterprise. There are two types of reports available: - Built-in Reports–there are two built-in reports available that provide the historical monitoring data for the devices and the groups.
Monitoring and Capping Power in Data Center For more information about using REST APIs, refer to OpenManage Enterprise Power Manager REST API Guide. 2.1.2 Analyzing Historical data This section describes how to use the historical graphs to identify the anomalies and identify the optimal power cap value for the devices and groups. After 7 days of monitoring, select a device for which you want to identify the anomalies. 1. Click the device and navigate to Power Management and Monitoring tab. 2.
Monitoring and Capping Power in Data Center d. Navigate to Policy Schedule and select the timeframe appropriately such that the capping is applied only for that duration. Identify this timeframe from the Analyzing Historical data section. For example, you can select Time Span as 2 PM to 4 PM. Also, you can select Days as Daily and as a recurrence from Monday to Friday. e. If you want to provide this power cap only for two months, provide a range in Active Span section.
Understanding Top Offenders and Top Energy Consumers 3 Understanding Top Offenders and Top Energy Consumers The following section provides information about the Top Offenders and Top Energy Consumers amongst all the devices and groups being monitored by Power Manager. 3.1 Top Offenders Top Offenders is a feature of Power Manager that lists out the Top 10 power and thermal threshold offenders.
Understanding Top Offenders and Top Energy Consumers 3.2 Top Energy Consumers Energy consumption is directly proportionate to power consumption. The higher the energy consumed, higher is the power consumed. In Power Manager, details about the top five energy consuming devices and groups are displayed. This data is available on Home page of OpenManage Enterprise, under the Power Manager widget. Use this list to identify the devices and groups that are consuming the highest power in a data center.
Using Physical Hierarchy 4 Using Physical Hierarchy Power Manager version 1.2 has introduced a feature called Physical Hierarchy. This feature helps you to create physical groups in OpenManage Enterprise to resemble an actual data center. Four categories of physical groups are supported–Data Center, Room, Aisle and Rack. Use physical groups to logically group the devices based on their physical location in a data center and monitor them. Some important features of physical hierarchy are: 1.
Using Physical Hierarchy Top 10 Underutilized Racks (Power) 4.2 Top 10 Underutilized Racks (Space) This dashlet provides information about the racks that are consuming the least space in the data center. This information allows you to perform capacity planning and identify the racks that have the capacity to accommodate more devices. This information is useful when you are planning to purchase more devices for your data center.
Using Physical Hierarchy Top 10 Underutilized Racks (Space) Additionally, there are built-in reports available to provide information about the space capacity and power capacity of all the racks being monitored in Power Manager. For more information about using built-in reports, see the Usage of Reports in Data Center through Dell EMC OpenManage Enterprise Power Manager whitepaper posted on the support site.
Using Dashboard 5 Using Dashboard The Home page of OpenManage Enterprise hosts the Power Manager specific dashlets. Each dashlet provides quick access to Power Manager specific data. This section focuses on using these dashlets effectively. 5.1 Power History Use this dashlet to select the most critical groups and get quick access to the power consumption of these groups. Using the edit icon, add a maximum of up to three critical groups to this dashlet.
Using Dashboard Thermal History Dashlet 5.3 Top Energy Consumers This dashlet has been described in the previous section. 5.4 Device Statistics This dashlet displays two bars–Capable Devices and Monitored Devices. The Capable Devices bar represents the devices discovered in OpenManage Enterprise that are supported and can be added to Power Manager. The Monitored Devices bar displays the number of devices that are being Monitored by Power Manager.

Disabling Power Manager 6 Disabling Power Manager Power Manager provides an option to disable the plugin. In certain cases, such as during maintenance work, there is no requirement to monitor the devices in the data center. This feature is useful during such instances where the functionality of the plugin is temporarily disabled, allowing you to focus on the critical tasks. You need to keep the following in mind before disabling the plugin.
Understanding Power Manager Settings 7 Understanding Power Manager Settings There are various Settings available in Power Manager that serve various purposes. This section specifies the use of each of these features. View the Power Manager Settings by navigating to Power ManagementSettings tab. 7.1 Monitoring Units Use this section to select the measurement units for power and thermal data.
Understanding Power Manager Settings Note: If the devices or groups are deleted from OpenManage Enterprise, then the data is deleted irrespective of whether this option is set to No. • Reset Metrics—use this option to reset the current cumulative energy consumption and the peak power consumption on the iDRAC console. If this option is enabled, these two values are reset periodically based on the Data Gathering Interval.
