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. This feature enables the power allocated to exceed the
redundant power capability of the Grid Redundant power supply configuration by up to 30% with all six
3000W AC power supplies.

1.2 Why EPP - Extended Power Performance on 3000W PSUs

Prior to CMC 4.5, the highest rated Power Supply Unit (PSU) supported in the M1000e chassis is the
2700W PSU. When customers select the Grid Redundancy policy, the M1000e chassis can have up to
7602W of DC power for the servers and infrastructure. Due to power constraints, manufacturing is unable
to ship M1000e chassis configurations of more than 16 M420 servers, or more than 7 M910 server
configurations to the customer. The redundant power demands of the full configuration of current
generation of servers have far exceeded the redundant power capabilities of the M1000e modular power
subsystem.

The new 3000W AC PSUs provides a solution to customers to support their high- end server
configurations in the M1000e Chassis. The Extended Power Performance (EPP) feature allows power
allocations by up to 130% when the Power subsystem is configured for Grid redundancy mode. The EPP
feature is applicable only when there are 6 power supply units, all power supply units are 3000W AC, and
Redundancy Policy is set to Grid Redundancy.

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.
