Chapter 2 Introduction to RAID 3

2 Introduction to RAIDRAID (Redundant Array of Independent Disks) is an array of multipleindependent hard disk drives that provide high performance and fault tolerance.A RAID disk subsystem improves I/O (input/output) performance over acomputer using only a single drive. The RAID array appears to the hostcomputer as a single storage unit or as multiple logical units. I/O is expeditedbecause several disks can be accessed simultaneously. RAID systems improvedata storage reliability and fault tolerance compared to single-drive computers.Data loss because of a disk drive failure can be prevented by reconstructingmissing data from the remaining data and parity drives.

RAID Benefits

RAID has gained popularity because it improves I/O performance, and increasesstorage subsystem reliability. RAID provides data security through faulttolerance and redundant data storage.

Improved I/O Although disk drive capabilities have improved drastically, actual performancehas improved only three to four times in the last decade. Computing performancehas improved over 50 times during the same time period. RAID allows you toaccess several disks simultaneously.

Increased Reliability The electromechanical components of a disk subsystem operate moreslowly, require more power, and generate more noise and vibration thanelectronic devices. These factors reduce the reliability of data stored on disks.RAID systems improve data storage reliability and fault tolerance compared tosingle-drive computers. The additional drives make it possible to prevent dataloss from a disk drive failure. You can reconstruct missing data from theremaining data and parity drives.

RAID Overview

RAID is a collection of specifications that describe a system for ensuring thereliability and stability of data stored on large disk subsystems. A RAID systemcan be implemented in a number of different versions (or RAID Levels). Thestandard RAID levels are 0, 1, 3, and 5.


Disk Striping

Disk striping writes data across multiple disk drives instead of just one diskdrive. Disk striping involves partitioning each drive storage space into stripesthat can vary in size. These stripes are interleaved in a repeated sequentialmanner. The combined storage space is composed of stripes from each drive.MegaRAID IDE supports stripe sizes of 32 KB to 4 MB.

For example, in a four-disk system using only disk striping (as in RAID level 0),segment 1 is written to disk 1, segment 2 is written to disk 2, and so on. Diskstriping enhances performance because multiple drives are accessedsimultaneously; but disk striping does not provide data redundancy.

Stripe Width Stripe width is the number of disks involved in an array where striping isimplemented. For example, a four-disk array with disk striping has a stripe widthof four.

Stripe Size The stripe size is the length of the interleaved data segments that are writtenacross multiple drives.


Disk Mirroring

With mirroring (used in RAID 1), data written to one disk drive issimultaneously written to another disk drive. If one disk drive fails, the contentsof the other disk drive can be used to run the system and reconstruct the faileddrive. The primary advantage of disk mirroring is that it provides 100% dataredundancy. Since the contents of the disk drive are completely written to asecond drive, it does not matter if one of the drives fails. Both drives contain thesame data at all times. Either drive can act as the operational drive.

Disk mirroring provides 100% redundancy, but is expensive because each drivein the system must be duplicated.


RAID Terminology

The following sections explains words associated with RAID, including:• physical drive• physical drive state• array• array state• logical drive• rebuild• hot spare• consistency check• fault tolerance

Physical Drive

The physical drive is the IDE hard disk that is connected by cable to theMegaRAID IDE card. The hard drive contains platters which are coated withmaterial so that allows them to record data magnetically. Another importantfeature is the read/write head, which hovers over the surface of the platter. Youcan store and access data much more quickly on a hard disk than on a floppydisk.

Physical Drive States

A physical disk drive can be in one of these states:State Description

Online The drive is functioning normally and is a part of aconfigured logical drive.

Spare The drive is powered up and ready for use as a spare in casean online drive fails.

Failed A fault has occurred in the drive placing it out of service.Rebuilding The drive is being rebuilt with data from a failed drive.

Array

A RAID array is a collection of physical disk drives governed by the RAIDmanagement software. A RAID array appears to the host computer as one ormore logical drives.

Array States

State DescriptionOnline The drive operating condition is good. All configured drives are

online.Degraded The drive operating condition is not optimal. One of the

configured drives has failed.Failed The drive has failed.Offline The drive is not available to MegaRAID IDE.


Logical Drive

A logical drive is a partition in a physical array of disks that is made up of contiguousdata segments on the physical disks. A logical drive can consist of an entire physical arrayor part of an array.

Disk Rebuild

You rebuild a disk drive by recreating the data that had been stored on the drive beforethe drive failed.

Rebuilding can be done only in arrays with data redundancy , such as RAID level 1.

MegaRAID IDE automatically and transparently rebuilds failed drives with user-definablerebuild rates. If a hot spare is available, the rebuild starts automatically when a drive fails.Rebuilding can start automatically at boot up also if the mirror drive is degraded and aspare is available.

Note: If a hot spare is not available, the failed disk drive must be replaced with a new disk driveso that the data on the failed drive can be rebuilt. The replacement disk drive capacitymust be greater than or equal to the failed drive it replaces.

Hot Spares

A hot spare is an extra, unused disk drive that is part of the disk subsystem. It is usually instandby mode, ready for service if a drive fails. Hot spares permit you to replace faileddrives without system shutdown or user intervention.

MegaRAID IDE implements automatic and transparent rebuilds using hot spare drives,providing a high degree of fault tolerance and zero downtime. The MegaRAID IDE BIOSconfigurator allows you to specify physical drives as hot spares. When a hot spare isneeded, MegaRAID IDE automatically selects the spare and include it in theconfiguration.

Please note that Spare drives are applicable only in arrays with redundancy, such as RAIDlevel 1.

Consistency Check

In RAID, check consistency verifies the correctness of redundant data in an array. It alsohelp to find disk errors. For example, in a system with a mirrored drive, checkingconsistency means making sure that both the member-drives of the mirror contains thesame data.

Fault Tolerance

Fault tolerance is achieved through the use of mirroring (RAID 1.) Mirroring provides100% redundancy. See Disk Mirroring on page 6 for more information.

Chapter 3 RAID Levels 9

3 RAID LevelsThere are six official RAID levels (RAID 0 through RAID 5). MegaRAID IDE supportsRAID levels 0, 1, and 10.

RAID Level Type turn to0 Standard page 91 Standard page 10

10 Standard page 11

RAID 0

RAID 0 provides disk striping across all drives in the RAID subsystem. RAID 0 does notprovide any data redundancy, but does offer the best performance of any RAID level.RAID 0 breaks up data into smaller blocks and then writes a block to each drive in thearray. The size of each block is determined by the stripe size parameter, set during thecreation of the RAID set. RAID 0 offers high bandwidth.

By breaking up a large file into smaller blocks, MegaRAID IDE can use multiple IDEchannels and drives to read or write the file faster. RAID 0 involves no parity calculationsto complicate the write operation. This makes RAID 0 ideal for applications that requirehigh bandwidth but do not require fault tolerance.

Uses RAID 0 provides high data throughput, especially for large files. Any environment that does notrequire fault tolerance.

Strong Points Provides increased data throughput for large files. No capacity loss penalty for parity.Weak Points Does not provide fault tolerance. All data lost if any drive fails.Drives One to four.


RAID 1

RAID 1 duplicates all data from one drive to a second drive. RAID 1 providescomplete data redundancy, but at the cost of doubling the required data storagecapacity.

Uses Use RAID 1 for small databases or any other environment that requires fault tolerance but smallcapacity.

Strong Points RAID 1 provides complete data redundancy. RAID 1 is ideal for any application that requiresfault tolerance and minimal capacity.

Weak Points RAID 1 requires twice as many disk drives. Performance is impaired during drive rebuilds.

Drives Two.

Chapter 3 RAID Levels 11

RAID 10

RAID 10 provides both RAID 0 (data striping) and RAID 1 (disk mirroring). It requirestwo sets of RAID 0 drives (total of four drives). In RAID 10, data is striped across thetwo arrays and duplicated from one drive to the second drive in each RAID 1 array.

Uses Use RAID 10 for small databases or any other environment that requires fault tolerance and highdata throughput, especially for large files.

Strong Points RAID 10 provides complete data redundancy. RAID 10 is ideal for any application that requiresfault tolerance and increased data throughput.

Weak Points RAID 10 requires a minimum of four disk drives. Performance is impaired during driverebuilds.

Drives Four drives.

Cable Suggestions System throughput problems and malfunctioning may occur if proper IDEcables are not used. We recommend that you use 80-conductor, 40-pin UltraATA cables for all drives. Two cables come with the retail package. The cablemanufacturer is Y.A. Cable USA, Inc. The cable part number is CBL-ATA66.

For ATA/66 or ATA/100 drives, 80-conductor, 40-pin Ultra ATA cables must beused, and the length of the cable must not exceed 18 inches. These cablesminimize noise level.

Note: Do not attach ATAPI drives to MegaRAID IDE. MegaRAID IDE does notsupport ATAPI devices, such as CD-ROM, SL120, and Zip drives. Connect onlyhard disk drives to the MegaRAID IDE adapter and connect ATAPI devices tothe IDE channels on the motherboard or to any other offboard IDE/ATAPIadapters.

Step 6 Power Up

Replace the computer cover and reconnect the AC power cords. Turn power onto the host computer. Set up the power supplies so that the IDE devices arepowered up at the same time as or before the host computer. If the computer ispowered up before an IDE device, the device might not be recognized.

During boot, the MegaRAID IDE Adapter ROM BIOS message appears:MegaRAID IDE BIOS Version x.x.x(c) Copyright 1985-2000 LSI Logic Corporation, USA

5 Configuring MegaRAID IDEThis chapter explains how to:

• configure MegaRAID IDE and arrays• assign RAID levels• plan the array configuration• optimize storage• use the MegaRAID IDE Setup Utility

Configuring Arrays

Organize the physical disk drives in arrays after the drives are connected toMegaRAID IDE. An array can consist of one to four physical disk drives,depending on the RAID level.

Configuration Strategies

The most important factors in RAID array configuration are drive availability(fault tolerance), and drive performance.

Maximizing Drive Availability You can maximize the drive availability by increasing faulttolerance. Use RAID 1 or mirror configuration to attain this objective.

Maximizing Drive Performance You can optimize drive performance by using striping. SelectRAID 0 or striping to configure an array for optimal performance.

Performance and Availability You can achieve both drive performance and availability. SelectRAID 10 for this configuration. You will need four drives to configure RAID 10.


Assigning RAID Levels

Only one RAID level can be assigned to each array. The drives required perRAID level is:

RAIDLevel

Minimum Number ofPhysical Drives

Maximum Number of PhysicalDrives

0 One Four1 Two Two

10 Four Four

Selecting a RAID Level

To ensure the best performance, you should select the optimal RAID level whenyou create a system drive. The optimal RAID level for your disk array dependson the following factors:

• Number of drives in the disk array• Capacity of the drives in the array• Need for data redundancy• Disk performance requirements

The factors you need to consider when selecting a RAID level are listed below.

Level Description and Use Pros Cons Numberof Drives

FaultTolerant

0 Data divided in blocksand distributedsequentially (purestriping). Use for non-critical data thatrequires highperformance.

High datethroughput forlarge files.

No faulttolerance. Alldata lost if anydrive fails.

Two Yes

10 Data divided in blocksand distributedsequentially and eachblock is duplicated toanother disk.

100 percentdataredundancy andHigh datathroughput.

A minimum offour drivesrequired.

Four Yes


Configuring Arrays

After you have installed the MegaRAID IDE controller in the system and haveattached all physical disk drives, perform the following actions to prepare aRAID disk array:

Step Action1 Press <Ctrl> <M> to run the MegaRAID IDE Manager.2 Define and configure one or more logical drives. See page 26 for more information.3 Create and configure one or more system drives (logical drives). Select the RAID level,

write cache policy, virus protection, and DMA transfers.4 Save the configuration.5 Initialize the system drives. After initialization, you can install the operating system.

Note: MegaRAID IDE does not support RAID arrays across different cards underMicrosoft Windows 95/98 Millennium and Microsoft Windows NT/2000.

Creating a Mirrored Array From an Existing Drive

To build a new mirrored array from an existing drive, connect the current driveand a new drive to the MegaRAID IDE card. Perform the following steps:

• Turn on the computer and Press <CTRL><M> to start the MegaRAID IDESetup Utility while it is booting.

• Create an array by using F4 Option. Change the array type to Mirror.• Now include the existing drive and the new drive to this array. You can

Create Array (F4), Continued

Stripe Size Stripe size field applies to stripe mode arrays only. By default, an array is set up with 64KB stripes. Edit this field to change the default stripe size. The options for the size of theStripes are listed in the table below.

STRIPE32 KB64 KB128 KB256 KB512 KB1024 KB2048 KB4096 KB

Note: You cannot change the stripe size of an array that has already been configured.

Bootable This determines which of the configured arrays should be used for booting the systemwhen MegaRAID IDE is selected as the boot device. The options are Yes or No.

BOOT OPTIONYESNO

You can select the boot device from the system BIOS setup. Only one array is allowed tobe bootable in a system.

Drive Size This field cannot be edited. It displays the size of the array. When the array type is stripe,the drive size is the total of all the drives selected (one or more drives.) When mirror,drive size is shown by individual drive, and when spare pool, drive size shows the totaldrive capacity.

Build Array The Build Array option is valid for RAID 1 (Mirror) and RAID 10 arrays only. It is usedto rebuild the array using a drive from the SPARE POOL. When Build Array starts, itwill prompt the user to select the target drive. It does this because both drives can be stillonline. Once the target drive is selected, the rebuild will start.

Note: A drive Rebuild can take a long time depending on the size of the drive. A 2 GB (UDMA5) drive takes two minutes to rebuild when DMA mode is enabled.

Delete Array (F5)

Press the <F5> key to delete a currently configured array. Use arrow keys to go over tothe array you want to delete and then press <F5>.

Caution

Use this option with caution. When you delete an array,you lose the array configuration and the data saved in

the array.


Restore Old Configuration (F6)

Press the <F6> key to restore the configuration that was there before you entered theMegaRAID IDE setup utility.

Edit Options (F7)

A status box for each item displays in the Physical Drives Information section of thescreen. The box shows whether the option is on or off. The Write Cache displays WC-ONor WC-OFF, the Virus Protection box displays VP-ON or VP-OFF, and the DMARead/Write box displays DMA-ON or DMA-OFF. When you turn the option on, thestatus box changes color, from red to green. The window for the Write Cache, VirusProtection, and DMA options is shown below.


Initialization (F8) (CNTRL-M)

This procedure initializes a logical drive to prepare it for the installation of anoperating system. The initialization deletes (writes 0 to) the initial 100 MB of thelogical drive created.

Initialization is the process of writing zeros to the data fields of a logical driveand, in fault-tolerant RAID levels, generating the corresponding parity to put thelogical drive in a Ready state. Initializing erases previous data and generatesparity so that the logical drive will pass a consistency check. Arrays will workwithout initializing, but they can fail a consistency check because the parityfields have not been generated.

Save and Exit (F10)

When you have completed the array configuration, press <F10> to save theconfiguration and exit. If you do not want to save the configuration or anychanges that you have made, press <Esc>. Subsequent message boxes display forconfirmation; respond to them appropriately. Note that when a new array isconfigured, its partition record is invalidated.

8 Troubleshooting

Drive Connection Tips

1. If you have two drives, connect one per channel.

2. The performance of MegaRAID IDE is best with one drive per channel.

3. Use the same type of drives or drives with similar capability (in terms of speed andcapacity).

4. Do not use dissimilar drives on the same channel.

5. Always use 80-conductor Ultra ATA cables.

6. Ensure that proper jumper settings are used for Master and Slave in each channel. Donot use the Cable Select jumper setting.

7. Do not connect any ATAPI devices (CD, ZIP, LS120 etc.) to the MegaRAID IDEcontroller.

Configuration and Setup Tips

1. Before installing any OS, switch Virus Protection OFF. This is required in order toprepare the partition sector (Master Boot Record.)

2. Set Drive Write Cache to ON for better performance. You must be careful whenusing this setting. If you lose power or do an improper shutdown, you may lose data.

3. For better performance in Windows, use FAT 32 for arrays less than 8.4 GB.

4. If you need to change array configuration, back up your data first. When an arrayconfiguration changes, previous data in that array is lost

5. If you get an unexpected message, such as “Drives Missing” or “ConfigurationMismatch”, switch off the system and verify all connections, IDE cables and powercables.

6. Before taking a drive off, always clear the configuration in that drive. If all drives areto be taken out, you can press <Ctrl><Q> after boot up to clear the configuration. Ifyou want to clear configuration in a single drive, use the “HyperFix” program.

7. If you get a “Configuration Mismatch” message after adding new drives, that isbecause the new drives had been used before and the configuration on the drives wasnot cleared. If this occurs, press <Ctrl><M> to go to the setup and create the arrayconfiguration as needed.

8. When you press <Ctrl><Q>, remember that you will lose all data in all the drives.


A note on Auto Configuration Options in the MegaRAID IDESetup Utility

The auto configuration options in the MegaRAID IDE BIOS setup utility are for autoconfiguration of Stripes, Mirrors and RAID 10. The auto configuration of stripes optionalways looks for drives in different channels. If found in different channels it clubs themtogether to form an array. For example, if there are four drives (two each in differentchannels), this option will configure two arrays with drives from different channels for thearray. But when there are two drives and they are all in the same channel, then this optionwill configure two arrays with one drive in each array. This is because the autoconfiguration for RAID 0 (Stripe) is based on performance.

For RAID 1 (Mirror), the auto configuration option a minimum of two drives arerequired. For RAID 10 auto configuration option, a minimum of four drives arerequired. Also, the RAID configuration does not support a stripe size less than 32 KB.

MegaRAID IDE drivers for Microsoft Windows based operating systems do not supportdrives across different controllers (physically separate cards). But the auto configurationoption takes all the drives from the system for configuration and it will club drives acrossthe controllers (physically separate cards) to form an array. So if you are going to usemore than one card, make sure that the drives in the array do not fall under differentcontrollers (physically separate cards).

MegaRAID IDE Console Tips

1. Install Internet Explorer 5.x or higher (Windows NT and Windows 9x only) beforeyou install MegaRAID IDE Console. (Not required)

2. Install NT Service Pack 5 or higher for Windows NT 4.0 before you installMegaRAID IDE Console. (Not required)

3. Note that if you uninstall Internet Explorer, MegaRAID IDE Console will not workproperly.

4. To track errors and start the Rebuilding option automatically when using the Mirror(Reliability) configuration, the background program “MegaRAID IDE Spy” isrequired. The background program is represented by an Icon in the System Tray(bottom right corner of your desktop).

5. You can stop MegaRAID IDE Spy by right clicking on the tray icon and thenselecting the Stop option.

6. It is recommended that you keep MegaRAID IDE Spy running all the time.

7. When MegaRAID IDE Console starts, it automatically starts MegaRAID IDE Spy.

8. If you do not want a drive to be marked as Failed in the Mirror configuration, rightclick on the MegaRAID IDE Console, select Properties and uncheck the option in theGeneral Settings tab.

9. Note that the physical drive errors are not erased once detected. If you want to clearthe log , use the “HyperFix” program.

10. The MegaRAID IDE driver ensures the Mirrored disks are always consistent. OnlyRun Consistency Check if you want to discover errors throughout the entire disk.

MegaRAID IDE Console Tips, Continued

11. The error log shows errors on the physical locations of hard disks. The errors arepotential problems, but do not necessarily cause data loss immediately. The FileSystem can take care of the error sector or the errors could fall outside of allpartitions.

Run ScanDisk in Windows 95/98/Me or Chkdsk in Windows NT for all partitions totake care of the errors.

Using HyperFix

Note the usage & options for HyperFix program.

/Dcd ---- Select the drive .

Where c = 0 for Primary Channel

1 for Secondary Channel

Where d = 0 for Master Drive

1 for Slave Drive

/Cn ------- Selects the card, where the addressed drive is present. Where 'n' is the card number starting from 0, 1..

/Eo ------ Erases & Displays the configuration sector of specified drive.

Where o = 'C' for Erase Configuration

'E' for Erase Error Log

'A' for Erase both Configuration and error Log

/U ------ Unlock the drive. Used to switch the drive from PowerUp-Standby to PowerUp-Active Mode.

Example:

"Hyperfix/D00/EC" means erase the configuration from the drive connected toPrimary Master.

"HYPERFIX /D10 /C2 /U" makes the Secondary Master in Card 2 to PowerUp in ActiveMode.


Problems and Suggestions

Problem Suggested SolutionThe MegaRAID IDE sign on message does notappear during boot up (If MegaRAID IDE card isproperly installed, you should see this message.)

1. Check whether the MegaRAID IDE card is insertedall the way down to the PCI slot.

2. Move the card to PCI slot.3. If System BIOS is set for silent boot, then no

message will appear on screen. This is not aproblem. To make sure, set the silent boot option todisabled in the system BIOS.

Drive(s) connected to MegaRAID IDE are notdetectedORThe system hangs when MegaRAID IDE adapterROM scans the IDE channels.

1. Make sure the Ultra ATA cables are used.2. Make sure that the cable ends are connected

properly.3. Make sure that the power cables to the drives are

connected properly.4. Make sure that the Master/Slave jumpers are used

properly.5. Change cables.6. If everything fails, change the drive(s).

BIOS reports that a mirrored array is in degradedmode.

Make sure all physical drives are properly connected andare powered on.Reconnect, replace, or rebuild any drive that has failed.

One of the hard drives in a mirrored array has failed. Replace the drive with another drive that has the samecapacity.

If this message displays while booting:“NO ROM BASICSYSTEM HALTED”

There are no active partitions. Run FDISK to set theactive partition.

Rebuilding does not take place inside theMegaRAID IDE BIOS setup utility.

Try disabling the DMA in the edit options using F7 key.In some cases the DMA based rebuilding may not work.

If the system hangs when more than one MegaRAIDIDE cards inserted.

Disable one of the EEPROMs in the MegaRAID IDEcard by jumper settings in the MegaRAID IDE Card..

Windows 9x (95, 98, Me) takes a long time tocomplete the installation process.

Make sure the Write cache is ON. You can set the writecache status using F7 key in the MegaRAID IDE BIOSSetup utility.

System hangs or blue screen appears whileinstalling Windows 98 during "11 minutesremaining" phase.

Make sure that the CDROM drive is connected properly.Also, verify the proper CD is inserted into the drive.

Operating system does not boot. Check the system BIOS configuration for PCI interruptassignments. Make sure some Interrupts are assigned forPCI.

Make sure that you have properly selected the BootDevice in the system BIOS setup (CMOS Setup).
