Intel® RAID Controller SRCSAS18E User’s Guidel v
When Using Your Computer System
As you use your computer system, observe the following safety guidelines:
Caution: Do not operate your computer system with any cover(s) (such as computer covers, bezels,
filler brackets, and front-panel inserts) removed:
• To help avoid damaging your computer, be sure the voltage selection switch on the
power supply is set to match the alternating current (AC) power available at your
location:
— 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countries such as Japan, South Korea, and Taiwan
— 230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure
your monitor and attached peripherals are electrically rated to operate with the
AC power available in your location.
• To help avoid possible damage to the server board, wait five seconds after turning off
the system before removing a component from the server board or disconnecting a
peripheral device from the computer.
• To help prevent electric shock, plug the computer and peripheral power cables into
properly grounded power sources. These cables are equipped with 3-prong plugs to
ensure proper grounding. Do not use adapter plugs or remove the grounding prong
from a cable. If you must use an extension cable, use a 3-wire cable with properly
grounded plugs.
• To help protect your computer system from sudden, transient increases and decreases
in electrical power, use a surge suppressor, line conditioner, or uninterruptible power
supply.
• Be sure nothing rests on your computer system’s cables and that the cables are not
located where they can be stepped on or tripped over.
• Do not spill food or liquids on your computer. If the computer gets wet, consult the
documentation that came with it.
• Do not push any objects into the openings of your computer. Doing so can cause fire
or electric shock by shorting out interior components.
• Keep your computer away from radiators and heat sources. Also, do not block cooling
vents. Avoid placing loose papers underneath your computer; do not place your
computer in a closed-in wall unit or on a rug.
When Working Inside Your Computer
Note: Do not attempt to service the computer system yourself, except as explained in this guide
and elsewhere in Intel documentation. Always follow installation and service instructions
closely.
1. Turn off your computer and any peripherals.
2. Disconnect your computer and peripherals from their power sources. Also disconnect
any telephone or telecommunications lines from the computer.
Doing so reduces the potential for personal injury or shock.
vi Intel® RAID Controller SRCSAS18E User’s Guidel
Also note these safety guidelines:
• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on
the cable itself. Some cables have a connector with locking tabs; if you are
disconnecting this type of cable, press in on the locking tabs before disconnect the
cable. As you pull connectors apart, keep them evenly aligned to avoid bending any
connector pins. Also, before you connect a cable, make sure both connectors are
correctly oriented and aligned.
• Handle components and cards with care. Don’t touch the components or contacts on a
card. Hold a card by its edges or by its metal mounting bracket. Hold a component
such as a microprocessor chip by its edges, not by its pins.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any of your
computer’s electronic components, such as the microprocessor. You can do so by
touching an unpainted metal surface, such as the metal around the card-slot openings at
the back of the computer.
As you continue to work inside the computer, periodically touch an unpainted metal
surface to remove any static charge your body may have accumulated. In addition to the
preceding precautions, you can also take the following steps to prevent damage from
electrostatic discharge (ESD):
• When unpacking a static-sensitive component from its shipping carton, do not remove
the component from the antistatic packing material until you are ready to install the
component in your computer. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
• When transporting a sensitive component, first place it in an antistatic container or
packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor
pads and workbench pads.

Benefits of SAS
SAS is a serial, point-to-point, enterprise-level device interface that leverages the proven
SCSI protocol set. SAS is a convergence of the advantages of SATA, SCSI, and FC, and is
the future mainstay of the enterprise and high-end workstation storage markets. SAS
offers a higher bandwidth per pin than parallel SCSI, and improves signal and data
integrity.
The SAS interface uses the proven SCSI command set to ensure reliable data transfers,
while providing the connectivity and flexibility of point-to-point serial data transfers. The
serial transmission of SCSI commands eliminates clock skew challenges. The SAS
interface provides improved performance, simplified cabling, smaller connectors, lower
pin count, and lower power requirements when compared to parallel SCSI.
SAS controllers leverage a common electrical and physical connection interface that is
compatible with Serial ATA technology. The SAS and SATA protocols use a thin, 7-wire
connector instead of the 68-wire SCSI cable or 40-wire ATA cable. The SAS/SATA
connector and cable are easier to manipulate, allow connections to smaller devices, and do
not inhibit airflow. The point-to-point SATA architecture eliminates inherent difficulties
created by the legacy ATA master-slave architecture, while maintaining compatibility with
existing ATA firmware.
3 Intel® RAID Controller SRCSAS18E User’s Guide
PCI Express* Architecture
PCI Express is a local bus system designed to increase data transfers without slowing
down the central processing unit (CPU). You can install the RAID Controller
SRCSAS18E in a PCI Express computer system that has a standard bracket type. With
this adapter in your system, you can connect SAS and SATA devices over the bus.
PCI Express goes beyond the PCI specification in that it is intended as a unifying I/O
architecture for various systems: desktops, workstations, mobile, server, communications,
and embedded devices.
Operating System Support
The RAID Controller SRCSAS18E supports major operating systems, such as:
• Windows 2000*, Windows Server 2003*, and Windows XP*
• Red Hat* Enterprise Linux 3.0 and 4.0

Drive Roaming
2
C) interface for enclosure management
Drive roaming occurs when the hard drives are changed to different ports on the same
controller. When the drives are placed on different ports, the controller detects the RAID
configuration from the configuration data on the drives.
Note: If you move a drive that is currently being rebuilt, the rebuild operation will restart, not
resume.
Perform the following steps to use drive roaming:
1. Turn off all power to the server and all hard drives, enclosures, and system
components, then disconnect power cords from the system.
2. Open the host system, following the instructions in the host system technical
documentation.
3. Move the drives to different positions on the backplane to change the targets.
4. Determine the SAS target requirements.
5. Perform a safety check.
— Make sure the drives are inserted properly.
— Close the cabinet of the host system.
— Turn power on after completing the safety check.
6. Power on the system.
The controller detects the RAID configuration from the configuration data on the drives.
Intel® RAID Controller SRCSAS18E User’s Guide 6
Drive Migration
Drive migration is the transfer of a set of hard drives in an existing configuration from one
controller to another. The drives must remain on the same port and be reinstalled in the
same order as in the original configuration. The controller to which you migrate the drives
cannot have an existing configuration.
Note: Only complete configurations can be migrated; individual virtual disks cannot be
migrated.
Note: Drive roaming and drive migration cannot be supported at the same time.
Perform the following steps to migrate drives:
1. Make sure that you clear the configuration on the system to which you migrate the
drives, to prevent a configuration data mismatch between the hard drives and the
NVRAM.
2. Turn off all power to the server and all hard drives, enclosures, and system
components, then disconnect power cords from the systems.
3. Open the host systems by following the instructions in the host system technical
documentation.
4. Remove the SAS cable connectors from the internal drives or the shielded cables from
the external drives you want to migrate.
— Make sure pin 1 on the cable matches pin 1 on the connector.
— Make sure that the SAS cables conform to all SAS specifications.
5. Remove the hard drives from the first system and insert them into drive bays on the
second.
6. Connect the SAS cables to the hard drives in the second system in the same order as
they were connected in the first system.
7. Determine the SAS target requirements.
8. Perform a safety check.
— Make sure all cables are properly attached.
— Make sure the RAID controller is properly installed.
— Close the cabinet of the host system.
— Turn power on after completing the safety check.
9. Power on the system.

SRCSAS18E. See “SAS Features“ on page 5 and “SAS Device Cables“ on page 12
for SAS cable information. See “Connecting the SAS RAID Controller to Hard Disk
Drives and Expanders“ on page 15 for details about connecting the controller to hard
disk drives and expanders.
11 Intel® RAID Controller SRCSAS18E User’s Guide
Note: System throughput problems can occur if using SAS cables that do not come with the
RAID controller and that are not the correct type. To minimize the potential for problems:
- Use cables no longer than ten meters for SAS and one meter for SATA. It is better to use
the shortest possible cables. The cable length should be reduced by about one foot (.33
meters) if using a backplane.
- You may connect one device per SATA/SAS cable either as a device or as an expander.
- Route SAS cables carefully
- Use only “straight” SAS cables, not “cross-over” SAS cables.
7. Power On Server
Replace the chassis cover and reconnect the AC power cord(s). Power up the SAS and
SATA devices before or at the same time as the server. If the computer is powered up
before a SAS or SATA device, the device might not be recognized.
During the boot, a BIOS message appears. The firmware takes several seconds to
initialize.
The configuration utility prompt times out after several seconds. The second portion of the
BIOS message displays the RAID Controller SRCSAS18E number, firmware version, and
cache SDRAM size. The numbering of the controllers follows the PCI slot scanning order
used by the host mainboard.
If you want to run the BIOS Console 2 utility, press the appropriate keys when this
message appears:
