INSTALLING CENTOS ON THE DELL POWEREDGE

C6220

Prerequisites

BIOS requirements

When installing CentOS 6.2 (64-bit), we used the default factory BIOS setting for

the server. Based on your workload requirements, BIOS settings may require

adjustment, but you should thoroughly test these changes prior to production

implementation.

Driver prerequisites

In our lab installation, we used a Dell PowerEdge C6220 with the LSI MegaRAID

SAS 9265-8i RAID controller. Using this storage controller, CentOS installs and runs

without extra hardware drivers or software modules on the Dell PowerEdge C6220.

Installation

Deployment options

We recognize in mass deployment situations there are various options for OS

deployment including Preboot eXecution Environment (PXE) or orchestration tools such

as Puppet. For this guide, however, we wish to prepare our “gold image” for CentOS on

a single Dell PowerEdge C6220 server node. To do this, we used its embedded

baseboard management controller (BMC) console and virtual installation media.

Storage configuration

The Dell PowerEdge C6220 can use several storage controllers to guard against

disk failures. For this guide, we assume that we wish to change the disk configuration

from the factory installation. We created one RAID6 virtual disk using the LSI MegaRAID

SAS 9265-8i RAID controller and the six 900GB internal hard drives assigned to the

server. We partitioned for the virtual disk for both OS and application data. Detailed

instructions on how to configure the storage controller are in Appendix C.

Installing the operating system

1. Using the BMC, assign the CentOS-6.2-x86_64-bin-DVD1 installation DVD to

the node and start the server.
