Use the following safety guidelines to help ensure your own personal safety and to help protect your system and working environment from potential damage.
WARNING: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. See "SAFETY: Battery Disposal" on page 11.
NOTE: For complete information on U.S. Terms and Conditions of Sale, Limited Warranties and Returns, Export Regulations, Software License Agreement, Safety, Environmental and Ergonomic Instructions, Regulatory Notices, and Recycling Information, see the Safety, Environmental and Regulatory Information, End User License Agreement, and Warranty and Support Information that shipped with your system.
•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 must 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 in 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° Celsius (140° Fahrenheit). Do not attempt to open or service batteries; replace batteries only with batteries designated for the product.
CAUTION: Safety Instructions |
|

|
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.
CAUTION: 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 connected devices.
2Disconnect your system and devices from their power sources. To reduce the potential of personal injury or shock, disconnect any telecommunication lines from the system.
3Ground yourself by touching an unpainted metal surface on the chassis before touching anything inside the system.
4While you work, periodically touch an unpainted metal surface on the chassis to dissipate any static electricity that might harm internal components.
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, when 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.
Electrostatic discharge (ESD) events can harm electronic components inside your system. 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 system. To prevent ESD damage, you must discharge static electricity from your body before you interact with any of your system’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 system’s I/O panel) before you interact with anything electronic. When connecting a peripheral (including handheld digital assistants) to your system, you should always ground both yourself and the peripheral before connecting it to the system. Additionally, as you work inside the system, periodically touch an I/O connector to remove any static charge your body may have accumulated.
10 |
CAUTION: Safety Instructions |
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.
Your system may use a nickel-metal hydride (NiMH), lithium coin-cell, and/or a lithium-ion battery. The NiMH, lithium coin-cell, and lithium-ion batteries are long-life batteries, and it is possible that you will never need to replace them.
NOTE: Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
NOTE: Your system may also include circuit cards or other components that contain batteries. These batteries too must be disposed of in a battery deposit site. For information about such batteries, see the documentation for the specific card or component.

14 Overview
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 0 uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy.
•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.
•RAID 10, a combination of RAID 0 and RAID 1, uses disk striping across mirrored disks. It provides high data throughput and complete data redundancy.
CAUTION: Lost data on a RAID 0 disk cannot be recovered in the event of a physical disk failure.
RAID 0 allows you to write data across multiple physical disks instead of just one physical disk. RAID 0 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 RAID 0, segment 1 is written to disk 1, segment 2 is written to disk 2, and so on. RAID 0 enhances performance because multiple physical disks are accessed simultaneously, but it does not provide data redundancy. Figure 2-2 shows an example of RAID 0.

With 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 RAID 1 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.

16 Overview
RAID 10 requires two or more mirrored sets working together. Multiple RAID 1 sets are combined to form a single array. Data is striped across all mirrored drives. Since each drive is mirrored in RAID 10, no delay is encountered because no parity calculation is done. This RAID strategy can tolerate the loss of multiple drives as long as two drives of the same mirrored pair do not fail. RAID 10 volumes provide high data throughput and complete data redundancy.

PERC H200 and 6Gbps SAS HBA Features |
|
23 |
|
The default cache policy on a physical disk is Enabled in SATA drives and Disabled on SAS drives. When physical disk caching is Enabled, disk I/O performance is improved, but a power outage or equipment failure might result in data loss or corruption.
NOTE: It is recommended that you use a backup power source for all Dell production systems.
On a PERC H200 card, caching is forced to be disabled for all physical disks configured into a virtual disk, regardless of the drive type and default drive settings.
Drives that are not certified by Dell are reported in the BIOS Configuration Utility, also known as <Ctrl><C>.
To view unsupported drives:
1In the BIOS Configuration Utility, navigate to the SAS Topology screen.
2Select the unsupported drive and press <Alt><D> to view the Device Properties screen.
The drive is marked as Uncertified in the Device Properties screen.
Drives that are not certified by Dell are not blocked and you can use them at your own risk.

Cards
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
1 Unpack the PERC H200 card or 6Gbps SAS HBA and check for damage.
NOTE: Contact Dell if the controller is damaged.
2Turn off the system and attached peripherals, and disconnect the system from the electrical outlet. See your system’s Hardware Owner’s Manual or the User’s Guide for more information on power supplies.
3Disconnect the system from the network and remove the cover of the system. See your system’s Hardware Owner’s Manual or the User’s Guide for more information on opening the system.
4Select an appropriate PCI-E slot. If replacing a PERC H200 Adapter or 6Gbps SAS HBA, remove the blank filler bracket on the back of the system aligned with the PCI-E slot you have selected.
