6 Dell Power Edge M1000e Chassis Management Controller Version 4.5 - Extended Power Performance Using 3000W
AC PSU
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.
Figure 2 EPP – Two levels of power gain, illustrates two levels of power gain. The first level of power gain
of 1038W is from the aggregate capacity gain from moving from three 2700W PSUs to three 3000W PSUs.
This first level of power gain is available for powering on additional servers. The second level is a power
gain of 2700W increasing the power gain for server performance by 30%. The two levels when combined
give a total power gain of 3738W (1038W + 2700W) in GRID redundancy.
