17 Dell Power Edge M1000e Chassis Management Controller Version 4.5 - Extended Power Performance Using 3000W
AC PSU
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. The
SPOPR setting is completely superseded by the EPP configuration setting. SPOPR is no longer supported
and grayed out on the 3000W AC power supply configuration as Extended Power Performance feature is
available to substitute for SPOPR.
3.2 EPP and Allow 110 VAC Operation
Since the 3000W AC power supplies can only operate on 220 VAC, the 110 VAC is not supported. The
“Allow 110VAC Operation” field grayed out on the CMC Web interface. The RACADM interface will block
the user from setting 110 VAC value if Noble CMC has the six 3000W AC power supply configuration.
3.2.1 EPP and Server Based Power Management (SBPM)
The Server Based Power Management (SBPM) feature is not compatible with EPP. The EPP feature is not
supported if SBMP is enabled.
3.3 EPP and Dynamic Power Supply Engagement (DPSE)
The Dynamic Power Supply Engagement (DPSE) feature is not compatible with EPP. The EPP feature is not
supported if DPSE is enabled.
3.4 EPP and Max Power Conservation Mode (MPCM)
Max Power Conservation Mode (MPCM) can be enabled on the 3000W AC PSU configuration, as shown
below. You are prompted to Click OK to continue, with a pop up message that the feature is not
supported while Extended Power Performance is enabled. Enabling MPCM brings down all server power
allocations to the respective Static Lower Boundary.
