5 Dell Power Edge M1000e Chassis Management Controller Version 4.5 - Extended Power Performance Using 3000W

AC PSU

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.
