Introduction 7 Introduction This guide outlines the steps for configuring the Dell™ P owerV ault™ Modular Disk 3000i (MD3000i). The guide also covers installing t he MD Storage Manager software, installing and configuring the Microsoft ® iSCSI and Linux initiators, and accessing documentation from the P owerV ault MD3000i Resource CD.
8 Introduction Introduction to Storage Array s A storage array includes various ha rdwar e components, such as physical disks, R AID controller modules, fans, and power supplies, gathered into enclosur es . An enclosur e containing physical disks accessed through R AID controller module s is called a RAID enclosur e.
