1.6 SAS/SATA Standards and Communication Protocols
The Intel® RAID Controller RS3UC080J supports the ANSI Serial Attached SCSI standard, version 3.0. In
addition, the controller supports the SATA III protocol defined by the Serial ATA specification, version 3.0.
Supporting both the SAS interface and the SATA interface, the SAS controller is a versatile controller that
provides the backbone of both server and high-end workstation environments.
Each port on your RAID controller supports SAS devices, S ATA devices, or both, by using the following
protocols:
• SAS Serial SCSI Protocol (SSP), which enables communication with other SAS devices
• SATA, which enables communication with other SATA devices
• Serial Management Protocol (SMP), which communicates topology management information directly
with an attached SAS expander device
• Serial Tunneling Protocol (STP), which enables communication with SATA devices through an attached
expander
SAS technology brings a wealth of options and flexibility with the use of SAS devices and SATA devices within
the same storage infrastructure. However, SAS devices and SATA devices bring individual characteristics that
make each one a more suitable choice depending on the requirements of the given operating environment
and storage needs. The Intel® RS3UC080J RAID Controller provides the flexibility to combine these two
storage technologies on the same controller and within the same enclosure. However combining different
rotational speed drives is not supported.
1.7 Safety Characteristics
All 12Gb/s Intel® RAID Controllers meet or exceed the requirements of UL flammability rating 94 V0. Each
bare board is also marked with the supplier name or trademark, type, and UL flammability rating.
1.8 Electrical Characteristics
1.8.1 Operating and Nonoperating Conditions for the Intel® RAID
Controller
Operating (thermal and atmospheric) limits are as follows:
• Relative humidity range is 20 percent to 80 percent noncondensing
• Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the SAS3008 processor
above the maximum ambient temperature
• Temperature range: +10°C to +55°C
Non-operating (such as storage and transit) limits are as follows:
• Relative humidity range is 5 percent to 90 percent noncondensing.
• Temperature range: –40°C to +70°C.

2 General Feature Overview
2.1 Benefits of the SAS Interface
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 Fiber Channel, and it is the mainstay of the
enterprise and high-end workstation storage markets.
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 the original parallel
SCSI.
SAS controllers leverage a common electrical and physical connection interface that is compatible with Serial
ATA (SATA) technology. The SAS protocols and the SATA III protocols use a common thin, 7-wire connector.
The SAS/SATA III connector and cable are easier to manipulate, allow connections to smaller devices, and do
not inhibit airflow. The point-to-point SATA III architecture eliminates inherent difficulties created by the
legacy ATA master-slave architecture, while maintaining compatibility with existing ATA firmware.

2.2.2 SATA III Features
• Supports SATA III data transfers of 6Gb/s
• Supports STP data transfers of 6Gb/s
• Provide a serial, point-to-point storage interface
• Simplify cabling between devices
• Eliminate the master-slave construction used in parallel ATA
• Permit addressing of multiple SATA targets through an expander
2.2.3 Usability Features

3 Hardware Installation
Warnings
Heed safety instructions: Before working with your server product, whether you are using this guide or any
other resource as a reference, pay close attention to the safety instructions. You must adhere to the assembly
instructions in this guide to ensure and maintain compliance with existing product certifications and
approvals. Use only the described, regulated components specified in this guide. Use of other
products/components will void the UL listing and other regulatory approvals of the product and will most
likely result in noncompliance with product regulations in the region(s) in which the product is sold.
System power on/off: The power button DOES NOT turn off the system AC power. To remove power from
the system, you must unplug all AC power cords from the server system before you open the chassis, add, or
remove any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the server and disconnect the power cord,
telecommunications systems, networks, and modems attached to the server before opening it. Otherwise,
personal injury or equipment damage can result.
Installing or removing jumpers: A jumper is a small plastic encased conductor that slips over two jumper
pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle
nosed pliers. If your jumpers do not have such a tab, take care when using needle nosed pliers to remove or
install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide
sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled
by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper,
or you may bend or break the pins on the board.
Electrostatic Discharge (ESD)
Electrostatic discharge can cause damage to your computer or the components within it. ESD can occur
without the user feeling a shock while working inside the system chassis or while improperly handling
electronic devices like processors, memory or other storage devices, and add-in cards.
Intel recommends the following steps be taken when performing any procedures described within this
document or while performing service to any computer system.
• Where available, all system integration and/or service should be performed at a properly equipped ESD
workstation
• Wear ESD protective gear like a grounded antistatic wrist strap, sole grounders, and/or conductive shoes
• Wear an anti-static smock or gown to cover any clothing that may generate an electrostatic charge
• Remove all jewelry
• Disconnect all cables and cords attached to the server before performing any integration or service
• Touch any unpainted metal surface of the chassis before performing any integration or service
• Hold all circuit boards and other electronic components by their edges only
• After removing electronic devices from the system or from their protective packaging, place them
component side up on to a grounded anti-static surface or conductive foam pad. Do not place electronic
devices on to the outside of any protective packaging.

is expedited because
RAID levels (RAID levels 1, 5, 6, 10, 50, and 60) provide
performance, simplified cabling, smaller connections, lower
count, and lower power requirements when compared to parallel SCSI. SAS controllers leverage a common
and physical connection interface that is compatible with Serial ATA.
SAS controllers support the ANSI Serial Attached SCSI Standard, Version 2.0. In addition, the controller supports
ATA III (SATA III) protocol defined by the Serial ATA Specification, Version 3.0. Supporting both the SAS
SATA III interface, the SAS controller is a versatile controller that provides the backbone of both
-end workstation environments. Each port on the SAS RAID controller supports SAS devices, SATA
-to-point connections between devices. The thinner serial cables allow for better airflow within the
