Chapter 1. Introduction

This chapter provides a brief introduction to the ThinkSystem DE series products. ThinkSystem DE series are

dedicated for high-bandwidth applications such as big data analytics, video-surveillance, and disk-based

backup that need simple, fast, and reliable SAN storage.

A storage array includes shelves, controllers, drives, software, and firmware. The array can be installed in a

rack or cabinet, with customizable hardware for two controllers, in a 12-, 24-, or 60-drive shelf. You can

connect the storage array to a SAN from multiple interface types and to a variety of host operating systems.
