Introduction to Power Manager

Dell EMC OpenManage Enterprise Power Manager is a plugin to the Dell EMC OpenManage Enterprise (OME) console and uses fine-grained instrumentation to provide increased visibility to power consumption, system anomalies, and resource utilization on

Dell EMC servers. Also, Power Manager supports virtual machine monitoring, and alerts and reports about power and thermal events in servers, chassis, and custom groups consisting of servers and chassis. This reporting enables increased control, faster response times, greater accuracy, and broader decision-making intelligence than is otherwise possible.

When used with PowerEdge servers, modular systems with an iDRAC Enterprise or iDRAC Datacenter license, or supported chassis and OpenManage Enterprise Advanced license, Power Manager leverages information from the OME console to deliver platform-level power reporting. Power Manager then communicates with Integrated Dell Remote Access Controller (iDRAC) or

Chassis Management Controller (CMC) on each managed device to provide power-management data and execution of control policy—making it easy for administrators to identify areas in which they can gain efficiencies and cut wasteful costs. Also,

Power Manager supports monitoring and managing power load on Power Distribution Units (PDUs) by communicating with the

PDU firmware.

Role and scope-based access control in OpenManage

Enterprise

OpenManage Enterprise has Role Based Access Control (RBAC) that clearly defines the user privileges for the three built-in roles—Administrator, Device Manager, and Viewer. Additionally, using the Scope-Based Access Control (SBAC) an administrator can limit the device groups that a device manager has access to. The following topics further explain the RBAC and SBAC features.

Role-Based Access Control (RBAC) privileges in OpenManage Enterprise

Users are assigned roles which determine their level of access to the appliance settings and device management features. This feature is termed as Role-Based Access Control (RBAC). The console enforces the privilege required for a certain action before allowing the action.

This table lists the various privileges that are enabled for each role.

Scope-Based Access Control (SBAC) in OpenManage Enterprise

With the use of Role-Based Access Control (RBAC) feature, administrators can assign roles while creating users. Roles determine their level of access to the appliance settings and device management features. Scope-based Access Control (SBAC) is an extension of the RBAC feature that allows an administrator to restrict a Device Manager role to a subset of device groups called scope.

While creating or updating a Device Manager (DM) user, administrators can assign scope to restrict operational access of DM to one or more system groups, custom groups, and / or plugin groups.

Administrator and Viewer roles have unrestricted scope. That means they have operational access as specified by RBAC privileges to all devices and groups entities.

Scope can be implemented as follows:

1. Create or Edit User

2. Assign DM role

3. Assign scope to restrict operational access

When a Device Manager (DM) user with an assigned scope logs in, the DM can see and manage scoped devices only. Also, the

DM can see and manage entities such as jobs, firmware or configuration templates and baselines, alert policies, profiles, and so on associated with scoped devices, only if the DM owns the entity (DM has created that entity or is assigned ownership of that entity). For more information about the entities a DM can create, see Role-Based Access Control (RBAC) privileges in

OpenManage Enterprise .

In OpenManage Enterprise, scope can be assigned while creating a local or importing AD/LDAP user. Scope assignment for

OIDC users can be done only on Open ID Connect (OIDC) providers.

SBAC for Local users:

While creating or editing a local user with DM role, admin can select one or more device groups that defines the scope for the

DM.

For example, you (as an administrator) create a DM user named dm1 and assign group g1 present under custom groups. Then dm1 will have operational access to all devices in g1 only. The user dm1 cannot access any other groups or entities related to any other devices.

Furthermore, with SBAC, dm1 will also not be able to see the entities created by other DMs (let us say dm2) on the same group g1 . That means a DM user will only be able to see the entities owned by the user.

For example, you (as an administrator) create another DM user named dm2 and assign the same group g1 present under custom groups. If dm2 creates configuration template, configuration baselines, or profiles for the devices in g1 , then dm1 will not have access to those entities and vice versa.

A DM with scope to All Devices has operational access as specified by RBAC privileges to all devices and group entities that are owned by the DM.

SBAC for AD/LDAP users:

While importing or editing AD/LDAP groups, administrators can assign scopes to user groups with DM role. If a user is a member of multiple AD groups, each with a DM role, and each AD group has distinct scope assignments, then the scope of the user is the union of the scopes of those AD groups.

For example,

● User dm1 is a member of two AD groups ( RR5-Floor1-LabAdmins and RR5-Floor3-LabAdmins ). Both AD groups have been assigned the DM role, with scope assignments for the AD groups are as follows: RR5-Floor1-LabAdmins gets ptlab-servers and RR5-Floor3-LabAdmins gets smdlab-servers . Now the scope of the DM dm1 is the union of ptlab-servers and smdlabservers .

● User dm1 is a member of two AD groups ( adg1 and adg2 ). Both AD groups have been assigned the DM role, with scope assignments for the AD groups as follows: adg1 is given access to g1 and adg2 is given access to g2 . If g1 is the superset of g2 , then the scope of dm1 is the larger scope ( g1 , all its child groups, and all leaf devices).

When a user is a member of multiple AD groups that have different roles, the higher-functionality role takes precedence (in the order Administrator, DM, Viewer).

A DM with unrestricted scope has operational access as specified by RBAC privileges to all device and group entities.

SBAC for OIDC users:

Scope assignment for OIDC users does not happen within the OME console. You can assign scopes for OIDC users at an OIDC provider during user configuration. When the user logs in with OIDC provider credentials, the role and scope assignment will be available to OME.

Compatibility matrix 13

For more information about configuring user roles and scopes, see Configure an OpenID Connect provider policy in PingFederate for role section in OpenManage Enterprise User's Guide .

Transfer ownership: The administrator can transfer owned resources from a device manager (source) to another device manager. For example, an administrator can transfer all the resources that are assigned from a source dm1 to dm2. A device manager with owned entities such as policies and EPR can transfer them to another device manager.

For more information see, Transfer of ownership of Device Manager entities section in OpenManage Enterprise User's Guide.

Licensing behavior in Power Manager for devices:

● If the OpenManage Enterprise Advanced license on the target devices is expired or deleted, the devices are removed from

Power Manager. You must re-add the devices to Power Manager after adding the license.

● If EPR is enabled on a device, and the device is removed from Power Manager due to an expired or deleted license, then you cannot access the device through Power Manager. To disable EPR, go to the iDRAC or CMC page of the device and remove the EPR.

● If policy and alert thresholds are set on a device, and the device is removed from Power Manager due to an expired or deleted license, then the policy and alert thresholds are removed from the device.

Licensing behavior in Power Manager for groups:

● For a group, only the devices that have a valid license are added as part of the group into Power Manager. Metrics are collected only for these devices in the group.

● If the OpenManage Enterprise Advanced license is expired or deleted from the target devices that are part of a group, the devices are removed from Power Manager. After updating the license, these devices are automatically added to Power

Manager in the next inventory cycle.

License requirements 15

● If EPR is enabled on a group, and if the license is expired or deleted for any device in a group, the device is not removed from Power Manager.

● If EPR is enabled on a group, you cannot remove the group or any device that is part of the group from Power Manager.

Scalability and performance

Power Manager supports up to 8,000 target devices that include 500 groups—static and physical groups, servers, virtual machines, and Power Distribution Units (PDUs).

Configure appropriate power and temperature sampling intervals in Power Manager. The sampling intervals impact the system performance and footprint significantly, including network bandwidth consumption, database size, and trend graph display latency.

The default power and temperature intervals in Power Manager are 15 minutes. This value is appropriate for small or mediumsized environments where the device number is less than 1,000. However, when the environment has more managed devices, the interval is automatically set to 30 minutes.

Virtual machines

Discovery feature discovers the hypervisors hosting virtual machines (VM) along with host servers. The virtual machines are listed in Guest Information section in OpenManage Enterprise. After adding the servers in Power Manager, the required hypervisor settings are automatically enabled by Power Manager to retrieve data that is related to virtual machines from the servers and the virtual machines are listed on the Power Manager Devices tab.

Hypervisors do not directly provide the power and energy consumption details of the VMs. Hence, Power Manager collects the

CPU usage data for each VM in the host and approximately calculates the power and energy that is consumed by the server to the individual VMs in the host. Use this feature to view resource consumption of each VM and to monitor and manage the servers hosting the VMs.

The following table lists the various operating system versions that are supported in Power Manager for monitoring virtual machines.

A VM is identified using a unique identifier, UUID for each VM. The list of VMs and their information is refreshed with each metric collection. If a new VM is created, or deleted, this information is reviewed in the next cycle. If the VM is migrated to another server, and if this new server is added to Power Manager, the VM is identified as same using the UUID and the metrics collection continues for the VM. In case the UUIDs do not match then the VM is detected as a new VM and Power Manager starts collecting the data as a new VM.

A VM cannot be added or removed manually from Power Manager. Only if the host server is added to Power Manager, the

VMs are automatically added to Power Manager. And, if the host server is removed from Power Manager or deleted from

OpenManage Enterprise, the VM is automatically removed from Power Manager.

Policies

Power Manager supports two types of policies you can use to monitor the power and temperature of your data center devices.

Static policy

A static policy contains various settings that help regulate the power consumption of a specific device or a group. A power management policy is useful in different situations. For example, you can create a policy to:

● Ensure that power consumption does not exceed the capacity of the circuit.

● Schedule power usage according to the workload of the device or group For example, to reduce the overall power use in your data center, apply an aggressive power cap policy when the workload is low.

● Increase rack density. For example, to increase the rack density or number of devices in a group you can set a power cap at a group level and add more servers. The policy cap keeps the power within the defined limit.

Temperature-triggered policy

A temperature-triggered policy is used to prevent damage to devices due to overheating in the event of cooling infrastructure failure. It limits the processing capability of the devices in the group, hence reducing the heat generation. The policy helps in maintaining the data center temperature to align to the standards defined by the American Society of Heating, Refrigerating and

Air-Conditioning Engineers (ASHRAE). Create a temperature-triggered policy on a group of devices by defining a temperature threshold value. After defining the threshold value and enabling the policy, if the average inlet temperature of the group crosses the temperature threshold value, Power Manager enforces an EPR—Throttle on the group. On the EPR page, the source of

EPR is displayed as Temperature-triggered—Throttle on the group.

NOTE: Temperature-triggered policies are applicable only for groups, and only one temperature-triggered policy is supported for a group.

NOTE: After applying a policy on a group, if you add more devices to the group and the power consumption exceeds the power cap, then you receive alerts in Alert Log with the recommended action.

Monitor and manage Power Manager devices 31

In multiple policies scenario, an active policy with a power cap value of 1000 Watts is applied on a device, and then another active policy with a power cap value of 1500 Watts is applied on the same device, the policy with power cap value of 1000 Watts is applied on the device as this policy is the most restrictive policy.

Create static or temperature-triggered policy

Create a static policy to limit the power consumption for devices and groups or apply EPR on devices in a group when the average inlet temperature exceeds the temperature threshold.

Prerequisites

Ensure that the following prerequisites are met:

● Devices or groups are added to Power Manager.

● Servers have the iDRAC and OpenManage Enterprise Advanced licenses.

○ If a device is PowerEdge VRTX or PowerEdge FX2 chassis, it has a Chassis Management Controller (CMC) Enterprise license.

About this task

NOTE: If you are logging in as a Device Manager, only the device groups and devices that are in your scope are available for viewing and management.

For example, if you are logging in as a Device Manager DM1 user, you can create policies on devices and groups that are in

Device Manager DM1 user scope.

When Device Manager users have common groups or devices in their scope, and Device Manager DM1 user creates a policy on any of these groups or devices:

● All the policies that are created by Device Manager DM1 user are not listed for other Device Manager users.

● If the Device Manager DM1 user creates a temperature-triggered policy on a group, the Device Manager DM2 user cannot create a temperature-triggered policy on the same group since only one temperature-triggered policy is supported on a group. And, the temperature-triggered policy is not visible or listed for Device Manager DM2 user. However, if the Device

Manage data center during power reduction

The Emergency Power Reduction (EPR) feature helps reduce power consumption of devices immediately during a power emergency. For example, if there is a power failure occurs and your devices are running on a UPS, you can apply EPR to reduce the power consumption of your managed devices.

EPR also helps in preventing device damage due to overheating in an event of cooling infrastructure failure. Use temperaturetriggered policies for enabling EPR on a group of devices when its average inlet temperature crosses a defined threshold value.

NOTE: Applying EPR on the devices throttles down the power to an extremely low level, impacting performance, or shuts down the devices completely. All devices on which an EPR is applied are affected. Use this feature only in an emergency situation.

Following are the EPR options available for servers, chassis, and groups:

● Throttle —set to minimal power consumption state.

NOTE: Only the Throttle option is supported for a chassis.

● Shut down —shut down the server

After applying EPR on devices and groups, they are marked as EPR Enabled (Throttle) or EPR Enabled (Shut down) on the

Power Manager Devices tab. The summary of devices and groups on which EPR is applied is displayed on the Emergency

Power Reduction tab in Power Manager .

Topics:

Enable Emergency Power Reduction

During a power shortage, enable the Emergency Power Reduction (EPR) on devices so that they run on minimal power.

About this task

NOTE: If you are logging in as a Device Manager, only the device groups and devices that are in your scope are available for viewing and management.

For example, if you are logging in as a Device Manager DM1 user, you can enable EPR on a device or group that is defined in Device Manager DM1 user scope. And, only the Device Manager DM1 user or the Administrator can disable the EPR, if it is applied manually.

When Device Manager users have common groups or devices in their scope, and Device Manager DM1 user applies EPR on any of these groups or devices:

● Other Device Manager users, administrators, and viewers can see the red color banner. However, the active EPR is listed on

Emergency Power Reduction and Policies and EPR tabs only for Device Manager DM1 user and not for any other Device

Manager users since it is not a shared resource.

● If temperature-triggered EPR is applied on a group or device, due to a temperature-triggered policy created by Device

Manager DM1 user, then all the other Device Manager users can see the red color banner with the source of EPR.

NOTE: Temperature-triggered EPR cannot be activated manually. When a temperature-triggered policy is active and the group temperature is equal to or exceeds the threshold value, Power Manager automatically applies the EPR.

Frequently Asked Questions

Why am I not able to view the metrics?

Cause : After removing the required iDRAC or DC License, or the OpenManage Enterprise Advanced Feature license, the license-dependent features are not available on the User Interface (UI). Therefore, the metric is not available, and the values are not collected by Power Manager from the next inventory cycle.

Why do I see two entries with the same date in the graph when the time duration chosen for showing the graph is changed?

Cause : When viewing the Metrics and Monitoring History graphs for 3 months, 6 months, or 1 year, the data is autoconverted from the UTC time zone to your current time zone and displayed. Due to the time zone differences, there are two entries for the same day on the graphs. Therefore, the last entry is for the current day, and the last but one entry is for the previous day.

Why do I see slight variations in values of power and temperature in the Alert Thresholds section?

Cause : When the power and temperature values are provided in BTU/Hour and Fahrenheit, they are converted to Watt and

Celsius. When the values are displayed, they are reconverted and rounded off to the next highest numbers. Therefore, the values are slightly higher when displayed in BTU/Hour and Fahrenheit scale.

Why are there same number of power cap or threshold violations for all the entries in my report?

Cause : For a in-built or custom report which consists of a violation attribute along with a timestamp attribute, the violation count that is displayed for all the entries is always for the latest value.

Why do I see blank entries for total energy consumed in reports or metrics graphs?

Cause : The Total Energy Consumed field has no entry for servers and PowerEdge MX7000 devices due to the following reasons:

● The energy consumption value is not available until the second metric collection is taken.

● If you change the Data gathering interval to 60 minutes, then for a 60 minutes time period the Energy Consumption value cannot be calculated. This happens when data is collected for a day with hourly granularity for reports.

● If the power metric in iDRAC is reset during the interval that is chosen, and the latest reading has a lower value than the oldest reading.

74 Frequently Asked Questions

Why do I not see all metric types for different types of devices?

Cause : Different devices support different types of metrics.

3. Click the View Details on the right side of the tab.

Details about the job are displayed.

In the Messages: section, check the status for Server Power Monitoring feature.

NOTE: If the Server Power Monitoring feature is disabled, then the device is not compatible with Power Manager .

Why do I see a failure of EPR in audit log but EPR is applied successfully for the device?

Cause : Applying EPR on the target device may fail due to the following reasons:

● Connectivity issues between the appliance and the target device.

● If the target device is part of Power Manager with an expired license.

Frequently Asked Questions 75

Why do I see a failure of EPR in audit log but EPR is applied successfully for the group?

Cause : When EPR option is applied for a group, and if the EPR option is applied successfully for at least one device in the group, the EPR banner is displayed at the group level. However, the EPR option may fail on other devices within the group due to connectivity issues or license expiry and so on. Therefore, use the EPR audit logs for successful and failure scenarios for all devices of the group.

Why are devices not listed for addition to Power Manager?

Cause : You cannot view certain devices in Power Manager because of the following reasons:

● If devices do not have OpenManage Enterprise Advanced license.

● If the devices are discovered in OpenManage Enterprise, and then Power Manager is installed, then the devices are not displayed in Power Manager until you Run Inventory on OpenManage Enterprise.

● Devices like switches, storage sleds, I/O modules are not supported in Power Manager.

● Servers that are discovered through the operating system(in-band) are not supported in Power Manager.

Why am I not able to install Power Manager?

Cause : There are two cases in which the installation of Power Manager may fail:

● If you have selected the online updates option in OpenManage Enterprise, check that the connectivity for the online path is successful.

● If you have selected the offline updates option in OpenManage Enterprise, ensure that the ome_powermanager_1.0.0.tar.gz

folder has all the files for the plugin catalog with the sign file and the plugin installer packages, including the RPMs. The installation fails if there is a mismatch between the catalog and .tar files.

Why am I not able to disable or uninstall Power Manager?

Cause : If active policies or an EPR option is enabled, you cannot disable or uninstall Power Manager.

Resolution : Disable the active policies and EPR option, and then try to disable or uninstall Power Manager.

Why are policies being disabled when too many policies are selected for deletion or disable or enable?

Cause : When you select multiple policies for enabling or disabling or deleting, the job is initiated. However, the policies are disabled on the user interface (UI) until the action is complete. After the job is complete, there are entries to the audit logs for these actions.

Why cannot I remove some devices or groups from Power

Manager?

Cause : If you have applied an Emergency Power Reduction (EPR) option on the device or a group, then you cannot remove the device or group from Power Manager.

Resolution : Disable the EPR option on the device or group, and then remove them from Power Manager.

76 Frequently Asked Questions

Why is Power Manager not listed on Console and plugins page?

Cause : Power Manager may not be listed due to the following reasons:

● The offline share folder is not accessible.

● Power Manager plugin and tar folder.s are not present in the offline share folder.

● If the plugin catalog file is edited, then the signature files can get corrupted.

Resolution : Ensure that the offline share folder is reachable through OpenManage Enterprise with the following files:

● ome_powermanager_1.0.0.tar.gz

● plugins_catalog

● plugins_catalog.json.asc

Frequently Asked Questions 77

Why do I not see temperature metric for some devices?

Cause : The temperature metric is not visible for devices if they are powered off.

Why can I not select a particular child group?

Cause : When you select a group, all the child groups within this group are also selected. Likewise, when you clear a child group the selection gets cleared at the main group level.

Why am I seeing No Data Available or No

Information available message for some devices metrics?

Cause : When the first metric collection has not yet happened or if the device is not reachable, the following message is displayed: No Data Available

When a device is not added to Power Manager even though it is a supported device, the following message is displayed: No

Information available .

Why are some of the fields in reports empty?

Cause : The fields may be empty in a report due to the following reasons:

● The device was not reachable for that duration.

● That category is not applicable for that device.

● The values are not defined for certain fields in Power Manager and these fields are part of the report.

For example, when you have not configured the power and temperature threshold values for a device, the following fields are added to the report, but the values are not populated:

○ Upper Warning Power

○ Upper Critical Power

○ Lower Critical Temperature

○ Lower Warning Temperature

○ Upper Warning Temperature

○ Upper Critical Temperature

If you have configured the above threshold values and only when the threshold values are violated, the following fields are populated and displayed in the report:

● Lower Critical Violation Count

● Lower Warning Violation Count

● Upper Critical Violation Count

● Upper Warning Violation Count

Why do I not see regular metric data points in the metric graphs?

Cause : A metric graph having irregular metric points indicate that data was not collected for that device at that duration of time.

78 Frequently Asked Questions

Why can I not clear the checkbox for policies?
