Before configuring RAID for your server, observe the following precautions:
1. Use hard disk drives that have the same capacity within a single RAID array.
2. Use hard disk drives that are of the same type (SATA or SAS) within a single RAID array.
3. Depending on the operating system, the primary RAID might be limited to 2 TB total drive capacity.
Configuring RAID using the ThinkServer EasyStartup program
The ThinkServer EasyStartup program simplifies the process of configuring supported RAID and installing
supported Windows and Linux operating systems and device drivers on your server. The user guide for the
program can be accessed directly from the program interface.
The ThinkServer EasyStartup program has the following features for RAID configuration:
• For use with all supported RAID controllers
• Automatically detects hardware and lists all supported RAID configurations
• Configures one or more disk arrays per controller depending on the number of drives attached to the
controller and the RAID level selected
• Supports hot-spare drives
• Creates a RAID response file that can be used to configure RAID controllers on similarly configured
Lenovo servers
See "Using the ThinkServer EasyStartup program" on page 69 and view the user guide from the main
interface of the program.
Some RAID management software is also provided on the ThinkServer EasyStartup DVD to help you manage
RAID arrays and RAID controllers in an operating system environment. After you enter the operating system,
insert the ThinkServer EasyStartup DVD into the optical drive. The installation packages for the programs are
located in the Utilities and Others folder in the root directory of the DVD. The ThinkServer EasyStartup DVD is
designed for different types of servers and the Utilities and Others folder might contain additional installation
packages that are not required to be installed into your server. For more information, see "Installing and
using the MegaRAID Storage Manager program" on page 79 and "Configuring the advanced SATA or SAS
hardware RAID" on page 79.
Configuring the onboard SATA software RAID
The onboard SATA software RAID controller is integrated in the Intel C202 chip on the system board. If your
server has SATA hard disk drives that are connected to the system board, you can use the LSI Software
RAID Configuration Utility program to configure RAID independently of the operating system. Your server
supports onboard SATA software RAID levels 0, 1, and 10. You can also activate RAID 5 by installing
a ThinkServer SATA Software RAID 5 activation key. See "Installing or removing the ThinkServer SATA
Software RAID 5 Key" on page 102.
You can install and use the MegaRAID Storage Manager program to manage the RAID array and RAID
controller in an operating system environment.
Starting the LSI Software RAID Configuration Utility program
This topic provides instructions on how to start the LSI Software RAID Configuration Utility program.
To start the LSI Software RAID Configuration Utility program, do the following:
1. Start the Setup Utility program. See "Starting the Setup Utility program" on page 55.
2. On the Advanced menu, select SATA Configuration ➙ SATA Mode.
3. Select RAID Mode. Then, press F10 to save settings and exit the Setup Utility program.
