20 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Chapter 2. SAN Boot implementation with IBM System Storage DS5000 2 In this chapter, we describe the host connectivity for the IBM System Storage DS5000 series storage subsystem and how to implement a host SAN Boot from DS5000 products. We address key aspects of host connectivity and review concepts and requirements for both Fibre Channel (FC) and Internet Small Computer System Interface (iSCSI) protocols. The term host refers to a server running a supported operating system. This chapter covers tasks that pertain to SAN Boot implementation. The following operating systems are described: ► Windows Server 2008 R2 ► Linux (RHEL, SUSE Linux Enterprise Server) ► AIX 6.1 ► VMware ESX 4.1 © Copyright IBM Corp. 2012. All rights reserved. 21
