Upgrading to Dell/EMC CX4 Series Storage Systems

Applied Technology 3

Executive Summary

Customers who purchase IT solutions are concerned about the return on investment (ROI) of their purchases.

Creating solutions that offer customers the ability to extend the usable life of an investment provides measurable

financial benefits.

The Dell/EMC CX4 series storage systems offer a data-in-place upgrade capability: As users’ performance,

capacity, or functionality requirements expand, the customer can upgrade from a CX or CX3 series storage system

to a CX4 series storage system with minimum impact to existing business processes. Because of the common

hardware architecture, upgrades can occur while keeping the data in place. This white paper discusses the reasons

for performing this hardware upgrade and the planning considerations.

Introduction

Dell/EMC CX4 series storage systems offer many advantages over the CX and CX3 series storage systems. For an

overview of what the CX4 series has to offer, see Introduction to the Dell/EMC CX4 Series Featuring UltraFlex

Technology at www.dell.com/emc. When deciding to invest in CX4 storage systems, a major consideration is

whether to perform a data-in-place upgrade for an existing system or buy a new CX4 system and leverage the

existing hardware elsewhere. This white paper discusses the advantages and disadvantages of both solutions and

discusses the considerations for performing a data-in-place upgrade.

Conversion kits permit the user to expand capacity, improve performance, and increase port count within the

Dell/EMC family of products. Current upgrade paths include support for converting an existing CX300/500/700 or

CX3 series into the new CX4 series.

If any of the presales considerations require significant work to prepare for the upgrade, Dell professional services

can be engaged to complete the necessary preparation work.

Audience

This white paper is intended for Dell customers, Dell system engineers, and members of the Dell professional

services community who are interested in learning more about a data-in-place upgrade to a CX4 series storage

system. It is the responsibility of the Dell presales technical resource to review these considerations when discussing

an upgrade with the customer.

The upgrade procedure is performed by a Dell service professional.
