CAUTION: Safety Instructions
Use the following safety guidelines to help ensure your own personal safety and to help protect
your system and working environment from potential damage.
NOTE: See the caution and safety statements in your Dell™ PowerEdge™ system
or Dell Precision™ workstation.
SAFETY: General
• Observe and follow service markings. Do not service any product except as explained in
your user documentation. Opening or removing covers that are marked with the triangular
symbol with a lightning bolt may expose you to electrical shock. Components inside these
compartments should be serviced only by a trained service technician.
• If any of the following conditions occur, unplug the product from the electrical outlet and
replace the part or contact your trained service provider:
– The power cable, extension cable, or plug is damaged.
– An object has fallen into the product.
– The product has been exposed to water.
– The product has been dropped or damaged.
– The product does not operate correctly when you follow the operating instructions.
• Use the product only with approved equipment.
• Operate the product only from the type of external power source indicated on the
electrical ratings label. If you are not sure of the type of power source required, consult
your service provider or local power company.
• Handle batteries carefully. Do not disassemble, crush, puncture, short external contacts,
dispose of in fire or water, or expose batteries to temperatures higher than
60 degrees Celsius (140 degrees Fahrenheit). Do not attempt to open or service batteries;
replace batteries only with batteries designated for the product.
SAFETY: When Working Inside Your System
Before you remove the system covers, perform the following steps in the sequence indicated.
CAUTION: Except if expressly otherwise instructed in Dell documentation, only trained
service technicians are authorized to remove the system cover and access any of the
components inside the system.
NOTICE: To help avoid possible damage to the system board, wait for 5 seconds after
turning off the system before removing a component from the system board or disconnecting
a peripheral device.
Safety Instructions 9
1
Turn off the system and any devices.
2
Ground yourself by touching an unpainted metal surface on the chassis before touching
anything inside the system.
3
While you work, periodically touch an unpainted metal surface on the chassis to dissipate any
static electricity that might harm the internal components.
4
Disconnect your system and devices from their power sources. To reduce the potential of
personal injury or shock, disconnect any telecommunication lines from the system.
In addition, take note of these safety guidelines when appropriate:
• 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 disconnecting the cable. As you pull the
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before
you connect a cable, make sure that 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.
SAFETY: Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) events can harm electronic components inside your computer.
Under certain conditions, ESD may build up on your body or an object, such as a peripheral, and
then discharge into another object, such as your computer. To prevent ESD damage, you should
discharge static electricity from your body before you interact with any of your computer’s internal
electronic components, such as a memory module. You can protect against ESD by touching a
metal grounded object (such as an unpainted metal surface on your computer’s I/O panel) before
you interact with anything electronic. When connecting a peripheral (including handheld digital
assistants) to your computer, you should always ground both yourself and the peripheral before
connecting it to the computer. In addition, as you work inside the computer, periodically touch an
I/O connector to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge:
• 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. Just before unwrapping the antistatic package, 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 electrostatic sensitive components in a static-safe area. If possible, use antistatic
floor pads and work bench pads.

Overview
The Dell™ Serial-Attached SCSI (SAS) 6/iR controller is Dell’s next generation
controller with integrated redundant array of independent disks (RAID)
capabilities. SAS technology is not backward compatible with the previous
generation of SCSI devices. All SAS 6/iR controllers are half-length, standardheight PCI-E cards, except for the SAS 6/iR Integrated controller on the blade
servers and on the Precision workstations. The SAS 6/iR controllers are
supported on platforms with PCI-E x4, x8 and x16 connectors.

Overview 11
About RAID
RAID is a group of multiple independent physical disks that provide high
performance or better data availability by increasing the number of drives
used for saving and accessing data. A RAID disk subsystem improves
I/O performance and data availability. The physical disk group appears to the
host system as a single storage unit. Data throughput improves because
multiple disks can be accessed simultaneously. RAID systems also improve
data storage availability and fault tolerance.
RAID Levels
RAID 0 uses disk striping to provide high data throughput, especially for large
files in an environment that requires no data redundancy.
Integrated Mirroring or RAID 1 uses disk mirroring so that data written to
one physical disk is simultaneously written to another physical disk. This is
good for small databases or other applications that require small capacity, but
complete data redundancy.
NOTICE: Lost data on an Integrated Striping virtual disk cannot be recovered in the
event of a physical disk failure.
RAID Terminology
Integrated Striping
Integrated Striping (RAID 0) allows you to write data across multiple physical
disks instead of just one physical disk. Integrated Striping involves partitioning
each physical disk storage space into 64 KB stripes. These stripes are
interleaved in a repeated sequential manner. The part of the stripe on a single
physical disk is called a stripe element.
For example, in a four-disk system using only Integrated Striping, segment 1 is
written to disk 1, segment 2 is written to disk 2, and so on. Integrated Striping
enhances performance because multiple physical disks are accessed
simultaneously, but Integrated Striping does not provide data redundancy.
Figure 2-2 shows an example of Integrated Striping.

stripe element 2

stripe element 3
stripe element 7
stripe element 11
stripe element 4
stripe element 8

Integrated Mirroring
With Integrated Mirroring (RAID 1), data written to one disk is
simultaneously written to another disk. If one disk fails, the contents of the
other disk can be used to run the system and rebuild the failed physical disk.
The primary advantage of Integrated Mirroring is that it provides 100 percent
data redundancy. Because the contents of the disk are completely written to a
second disk, the system can sustain the failure of one disk. Both disks contain
the same data at all times. Either physical disk can act as the operational
physical disk.
NOTE: Mirrored physical disks improve read performance by read load balance.
