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 safety and caution statements in your Product Information Guide that came with 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 as 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 5 seconds after turning off the system before removing a component from the system board or disconnecting a peripheral device.

1Turn off the system and any devices.

2Ground yourself by touching an unpainted metal surface on the chassis before touching anything inside the system.

3While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm internal components.

4Disconnect your system and devices from their power sources. To reduce the potential of personal injury or shock, disconnect any telecommunication lines from the system.

Safety Instructions		7

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 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) 5/iR controller is Dell’s next generation of controller with integrated redundant array of independent disks (RAID) capabilities. SAS technology is not backward compatible with the previous generation of SCSI devices. The SAS 5/iR Adapter is a half-length, standard-height PCI-E card, while the SAS 5/iR Integrated is embedded in the platform hardware. The SAS 5/iR Adapter is supported on platforms with PCI-E x8 or x16 connectors.

About RAID

RAID is a group of multiple independent physical disks that provide high performance 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 or as multiple logical units. Data throughput improves because multiple disks can be accessed simultaneously. RAID systems also improve data storage availability and fault tolerance.

RAID Levels

Integrated Striping or 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 1-2 shows an example of Integrated Striping.

Figure 1-2. Example of Integrated Striping (RAID 0)

Stripe element 1	Stripe element 2	Stripe element 3	Stripe element 4
Stripe element 5	Stripe element 6	Stripe element 7	Stripe element 8
Stripe element 9	Stripe element 10	Stripe element 11	Stripe element 12

10 Overview

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, it does not matter if one of the disks fails. 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.
