Single Memory Module Installation
If only one memory module is installed, it must be installed in socket DIMM1_B. Two-way
interleaving is not supported for this configuration. See the Installation and Troubleshooting Guide
for more information about memory modules.
Using a PERC 4/DC Controller
Only channel 0 of the PowerEdge™ Expandable RAID Controller 4/DC (PERC 4/DC) is rated for
use with the integrated SCSI controller in your system. Systems shipped from Dell with a
PERC 4/DC controller installed are already configured with the channel-0 connection and this
configuration should not be changed. If you add a PERC 4/DC controller to your system, you must
connect channel 0 of the PERC 4/DC controller to the SCSI backplane using the cable that is
supplied with the controller.
Creating an Embedded SATA Controller RAID Array
To easily create a RAID array when using the system’s embedded SATA controller, perform
the following steps:
1 Turn on your system.
2 Press immediately after you see the following message:
= Setup
See "System Setup Program" in the User’s Guide for additional information.
3 Enable RAID in the Integrated Devices options in the System Setup program.
4 See your CERC SATA 2s documentation for information on configuring RAID drives.
The CERC SATA 2s RAID driver is available at Dell Support at support.dell.com.
Using Red Hat Enterprise Linux, Dell OpenManage Server
Assistant, and the Embedded SATA Controller With RAID
The Red Hat Enterprise Linux operating system can be installed only by using the Red Hat
Enterprise Linux media if all of the following conditions exist:
• You are attempting to use Server Assistant to install Red Hat Enterprise Linux.
• The embedded SATA controller is enabled in the System Setup program
(see the User’s Guide for more information about the System Setup program).
This is because Server Assistant does not contain RAID drivers to support a Red Hat Enterprise
Linux operating system installation with the embedded SATA controller enabled in a RAID
configuration at this time. Therefore, the Red Hat Enterprise Linux operating system installation
option is not available in Server Assistant if those conditions listed above exist.
