1 Introduction This whitepaper provides an overview of the Extended Power Performance (EPP) feature enabled on 3000W AC Power Supplies. 1.1 What is Extended Power Performance The Extended Power Performance (EPP) feature is a new feature released in Chassis Management Controller (CMC) Version 4.5, which allows increased power allocations in the PowerEdge M1000e modular chassis to support high- end servers.
Figure 1 EPP Feature adds 30% Virtual Power in Six PSU Configuration (Extended Power Performance Enabled) EPP feature shall not allow any additional servers to power up compared to a configuration without EPP enabled on the 3000W AC power supply configuration. The additional power gained by upgrading power supplies from 2360W, or 2700W, to 3000W is available to power on additional servers. The additional EPP power pool is available only to increase the performance of the existing servers.

2 Managing EPP features on CMC interfaces This feature can be managed through the CMC Web interface and RACADM interface. The CMC Web interface supports the EPP feature for the following: • • • • EPP"feature"control,"(Enable/Disable)"using"Chassis Power Configuration"page. EPP"Status"using"Chassis Home Page EPP"Power"Monitoring"and"Statistics EPP"status"updates"captured"in"CMC"Log CMC RACADM CLI Interface support shall be available for the following: • • • • 2.
Figure 3 2.1.2 EPP feature control EPP Feature Status The Chassis Health page on the Web interface allows you to view the EPP status. The Power section displays one of the following status states: • • • • 9 Disabled Enabled"(active) Enabled"(inactive) Enabled"(unsupported) Dell Power Edge M1000e Chassis Management Controller Version 4.
Figure 4 2.1.3 EPP feature status on Chassis Health page EPP Power Monitoring and Statistics The Power Monitoring page on the Web interface allows you to monitor the EPP feature statistics. The following figures illustrate the statistics displayed for the various EPP status states: 10 Dell Power Edge M1000e Chassis Management Controller Version 4.
EPP Disabled: Figure 5 11 EPP Disabled Status on Power Monitoring Page. Dell Power Edge M1000e Chassis Management Controller Version 4.
EPP Enabled (active): Figure 6 EPP Enabled (active) Status on Power Monitoring Page. EPP Enabled (inactive): Figure 7 12 EPP Enabled (inactive) Status on Power Monitoring Page Dell Power Edge M1000e Chassis Management Controller Version 4.
EPP Enabled (unsupported): Figure 8 2.1.4 EPP Enabled (unsupported) Status on Power Monitoring Page EPP Error Reporting The Power Monitoring page on the Web interface allows you to view the EPP feature errors for the unsupported EPP status states: EPP Enabled (unsupported): Figure 9 Error Message describing why EPP is unsupported EPP Enabled (unsupported – multiple reasons) Figure 10 13 Multiple unsupported reasons describing why EPP is not supported.
EPP Disabled: Figure 11 When EPP is disabled. To view the EPP feature control related logs from CMC Web Interface, go to Logs and CMC logs: Figure 12 2.2 EPP Log Messages on CMC Web Interface. Managing EPP feature using RACADM interface: The following sections describe how to manage the EPP feature using the RACADM interface. 2.2.
0 = EPP is Disabled 2.2.3 EPP Feature Status To view the EPP feature status use the racadm getpbinfo command. The following are examples of the EPP status information displayed: • Example 1 $ racadm getpbinfo Extended Power Performance(EPP) Status = Enabled (inactive) Available Power in EPP Pool = 3167 W (10806 BTU/h) Used Power in EPP Pool = 0 W (0 BTU/h) EPP Percent - Available = 100.0 • Example 2 $ racadm getpbinfo 2.2.
Extended Power Performance(EPP) Status = Enabled (unsupported) Available Power in EPP Pool = 0 W (0 BTU/h) Used Power in EPP Pool = 0 W (0 BTU/h) EPP Percent - Available = 0.0 EPP Error Messages The feature is not supported with an unsupported PSU : PSU Slot 1. The feature is not supported with an unsupported PSU : PSU Slot 2. The feature is not supported with an unsupported PSU : PSU Slot 3. The feature is not supported with an unsupported PSU : PSU Slot 4.
3 EPP with Other Power Configurations: The following sections describe each power configuration which impacts the EPP Settings: 3.1 EPP and Server Performance Over Power Redundancy (SPOPR) The two features Extended Power Performance (EPP) and Server Performance Over Power Redundancy (SPOPR) are mutually exclusive. The SPOPR feature has been available for customers since the CMC 3.1 release. CMC 4.45 and earlier versions have shipped with SPOPR Enabled as the default setting.
Figure 13 3.5 Warning Message when user tries to Enabled MPCM while EPP is Enabled (active). EPP and Redundancy Policy “Power Supply Redundancy” and “No Redundancy” are not compatible with EPP. Modification of the Redundancy Policy from “Grid Redundancy” (factory shipped default setting), to “Power Supply Redundancy” or “No Redundancy” on EPP Enabled configuration is not possible. The incompatible options are grayed out on the Web interface as illustrated in Figure 12.

4 EPP Feature Constraints The EPP feature does not operate if: • • • • Any"power"supply"is"reporting"loss"of"Input"Voltage. Any"power"supply"is"in"a"state"other"than"Online,"for"example"Failed"state. Any"power"supply"is"reporting"loss"of"Output"Voltage."This"occurs"if"a"power"supply"is"in"failed"state" due"to"being"unable"to"convert"AC"to"DC"power,"or"if"a"PSU""failed"to"provide"FRU"data. Power"Redundancy"Status"is"lost,"for"example"due"to"PSU"failure.
