1 Overview
The Intel® RAID Module RMS2LL040 and RMS2LL080 provide reliable and faulttolerant disk subsystem management based on the Intel
Stack. This is an ideal RAID solution for the internal large capacity storage needs of mid
to low-end servers and workstations for use by workgroups and departmental-sized
organizations or individuals. The Intel
offer a cost-effective way to implement RAID in a server for internal storage.
As the second generation PCI Express* storage adapters, the Intel
RMS2LL040 and RMS2LL080 address the growing demand for increased data
throughput and scalability requirements across mid to low-end servers and workstations.
The controller can be connected to up to four drives (RMS2LL040) or eight drives
(RMS2LL080) directly and allows the use of expanders to connect to additional drives.
For more information about the use of expanders, see the ANSI SAS Standard, version 2.0
specification.
SATA and SAS are serial, point-to-point, device interfaces that use simplified cabling,
smaller connectors, lower pin counts, and lower power requirements than parallel SCSI.
Benefits of SAS and SATA
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.

RAID Module
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 than 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, connect to smaller devices, and do not
inhibit airflow. The point-to-point SATA architecture eliminates difficulties created by the
legacy ATA master-slave architecture, while maintaining compatibility with existing ATA
firmware.

RAID Functionality and Features
Hierarchy
The fundamental purpose of a RAID system is to present a usable data storage medium
(virtual drive) with some level of redundancy to a host operating system. The Intel®
RAID firmware is based on the concept of associating physical drives in arrays and then
creating a virtual drive from that array that includes a functional RAID level. To create a
virtual drive and present it to the host operating system, the RAID firmware typically
follows these steps:
1. One or more physical drives are selected and associa
2. One or more arrays are associated and given a RAID level. This process creates a
virtual drive and provides an opt
3. The RAID firmware presents the virtual drive to the operating system.

Safety Instructions
As you use your computer system, observe these safety guidelines:
• 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.
• 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:
• 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.
• Turn off your computer and any peripherals.
• 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.
Intel® RAID Module RMS2LL040 and RMS2LL080 Hardware User’s Guide 25
Additional 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. Do not 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.
