IBM BladeCenter Deployment Guide

1 Introduction

1.1 Overview

The IBM BladeCenter Deployment Guide is intended to present the general steps necessary to

successfully deploy IBM blades in the IBM® BladeCenter™. Its primary focus is to detail the steps required for setting up remote boot on IBM Blades. The information provided in this document is based on technical observations.

Due to the breadth of content related to this topic, this guide has now been split into 3 parts.

1.Management Module – information specific to the initial setup and ongoing usage of the Management Module.

2.Embedded Switches – information related to the configuration of the embedded Ethernet and Fibre channel switches.

3.Blades – blade configuration and installation information with a primary focus of installing Linux in a boot to SAN environment.

Remote boot, root boot, or boot from SAN, is the name referred to the server configuration where the server operating system is installed on a logical drive (LUN) that does not reside inside the server chassis. This document will describe in detail the process that one must go through to setup a remote boot for HS20 or HS40 blade servers. The blade servers utilize the IBM BladeCenter Fibre Channel Expansion Card connected to the BladeCenter Fibre Channel Switch Modules via the BladeCenter backplane. The switch modules in turn are connected to the core fibre channel switches that host the SAN Fabric.

This document is a supplement the IBM® BladeCenter™ publications provided with the BladeCenter products. In addition to the publications being provided with the BladeCenter products, they also are available in Portable Document Format (PDF). The latest versions of the publications are available from the IBM web site at http://www.ibm.com/pc/support/.

BladeCenter publications include the following:

IBM BladeCenter Type 8677 Planning and Installation Guide: This manual provides physical planning information for the IBM BladeCenter products. It describes the BladeCenter components, explains deployment and installation considerations, and provides worksheets that you can use to determine the configuration, power, weight, and cabling requirements for your BladeCenter unit. (http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-53670)

IBM BladeCenter Type 8677 Installation and User’s Guide. This document contains general information about your BladeCenter unit, including information about features, how to configure your BladeCenter unit, and how to get help. It is provided with the BladeCenter unit and is on the IBM BladeCenter Documentation CD.

IBM BladeCenter Management Module User Guide: This guide contains information about configuring the management module and managing components installed in BladeCenter chassis. (http://www-1.ibm.com/support/docview.wss?rs=0&uid=psg1MIGR-45153)

IBM xSeries and BladeCenter Server Management (SG24-6495): This document covers the hardware side of the IBM systems management solution including the BladeCenter management module. It is available for download from the IBM Web site at http://www.ibm.com/redbooks/.

1.2 BladeCenter Subsystems

The various BladeCenter Subsystems include:

Server Blades - provide the processors, memory, hard disk(s) and firmware of an industry standard server. In addition, they will normally incorporate keyboard, video, and mouse interfaces, and an onboard service processor.

Management Modules – incorporate the chassis-level management processor and Keyboard/Video/Mouse (KVM) access for the blades.

Switch Modules - provide multiple high-speed Ethernet ports in Switch Module slots 1 and 2 for use by all of the Server Blades to interconnect internally as well as to external network devices. Switch
