11 1 Overview The MegaRAID IDE RAID Controller is a short PCI Adapter card that provides two IDE channels with Ultra ATA/66 (MegaRAID IDE) or Ultra ATA/100 (MegaRAID IDE 100) capability. MegaRAID IDE provides a simple and cost effective way to improve the performance and reliability of your storage subsystems. MegaRAID IDE offers high transfer rates, and fault-tolerant data redundancy during high performance applications by using low cost Ultra ATA drives in desktops, workstations, or low-end servers. You can connect from one to four drives to this card using IDE cables (Ultra ATA drives need special IDE cables) and configure these drives using a simple setup menu embedded in the MegaRAID IDE BIOS. The card supports the following drive modes: PIO 0-4, DMA 0-2, and Ultra DMA 0-5. In addition, it supports RAID levels 0, 1 and 10. You can use striping (RAID 0) to improve performance or mirroring (RAID 1) to improve data security. RAID 10 provides both RAID 1 (disk mirroring) and RAID 0 (data striping.) This manual describes the MegaRAID IDE controller. IDE Channels MegaRAID IDE supports two IDE channels. IDE Connectors MegaRAID IDE has two 40-pin internal connectors. Controller BIOS features MegaRAID IDE provides a single chip solution for a PCI to IDE/ATA controller. It receives PCI commands and data, which it processes and sends to the IDE/ATA bus.

13 2 Introduction to RAID RAID (Redundant Array of Independent Disks) is an array of multiple independent hard disk drives that provide high performance and fault tolerance. A RAID disk subsystem improves I/O (input/output) performance over a computer using only a single drive. The RAID array appears to the host computer as a single storage unit or as multiple logical units. I/O is expedited because several disks can be accessed simultaneously. RAID systems improve data storage reliability and fault tolerance compared to single-drive computers. Data loss because of a disk drive failure can be prevented by reconstructing missing data from the remaining data and parity drives. RAID Benefits RAID has gained popularity because it improves I/O performance, and increases storage subsystem reliability. RAID provides data security through fault tolerance and redundant data storage. Improved I/O Although disk drive capabilities have improved drastically, actual performance has improved only three to four times in the last decade. Computing performance has improved over 50 times during the same time period. RAID allows you to access several disks simultaneously. Increased Reliability The electromechanical components of a disk subsystem operate more slowly, require more power, and generate more noise and vibration than electronic devices. These factors reduce the reliability of data stored on disks. RAID systems improve data storage reliability and fault tolerance compared to single-drive computers. The additional drives make it possible to prevent data loss from a disk drive failure. You can reconstruct missing data from the remaining data and parity drives. Chapter 2 Introduction to RAID 3

A RAID system can be implemented in a number of different versions (or RAID Levels). The standard RAID levels are 0, 1, 3, and 5. 4 MegaRAID IDE (ATA/66) and MegaRAID IDE 100 (ATA/100) User's Guide

15 Disk Striping Disk striping writes data across multiple disk drives instead of just one disk drive. Disk striping involves partitioning each drive storage space into stripes that can vary in size. These stripes are interleaved in a repeated sequential manner. 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. Disk striping enhances performance because multiple drives are accessed simultaneously; but disk striping does not provide data redundancy. Stripe Width Stripe width is the number of disks involved in an array where striping is implemented. For example, a four-disk array with disk striping has a stripe width of four. Stripe Size The stripe size is the length of the interleaved data segments that are written across multiple drives. Chapter 2 Introduction to RAID 5

16 Disk Mirroring With mirroring (used in RAID 1), data written to one disk drive is simultaneously written to another disk drive. If one disk drive fails, the contents of the other disk drive can be used to run the system and reconstruct the failed drive. The primary advantage of disk mirroring is that it provides 100% data redundancy. Since the contents of the disk drive are completely written to a second drive, it does not matter if one of the drives fails. Both drives contain the same data at all times. Either drive can act as the operational drive. Disk mirroring provides 100% redundancy, but is expensive because each drive in the system must be duplicated. 6 MegaRAID IDE (ATA/66) and MegaRAID IDE 100 (ATA/100) User's Guide

17 RAID Terminology Physical Drive 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 The physical drive is the IDE hard disk that is connected by cable to the MegaRAID IDE card. The hard drive contains platters which are coated with material so that allows them to record data magnetically. Another important feature is the read/write head, which hovers over the surface of the platter. You can store and access data much more quickly on a hard disk than on a floppy disk. Physical Drive States Array Array States A physical disk drive can be in one of these states: State Description Online Spare Failed Rebuilding The drive is functioning normally and is a part of a configured logical drive. The drive is powered up and ready for use as a spare in case an online drive fails. A fault has occurred in the drive placing it out of service. The drive is being rebuilt with data from a failed drive. A RAID array is a collection of physical disk drives governed by the RAID management software. A RAID array appears to the host computer as one or more logical drives. State Online Degraded Failed Offline Description The drive operating condition is good. All configured drives are online. The drive operating condition is not optimal. One of the configured drives has failed. The drive has failed. The drive is not available to MegaRAID IDE. Chapter 2 Introduction to RAID 7

18 Logical Drive Disk Rebuild A logical drive is a partition in a physical array of disks that is made up of contiguous data segments on the physical disks. A logical drive can consist of an entire physical array or part of an array. You rebuild a disk drive by recreating the data that had been stored on the drive before the 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-definable rebuild 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 a spare is available. Note: If a hot spare is not available, the failed disk drive must be replaced with a new disk drive so that the data on the failed drive can be rebuilt. The replacement disk drive capacity must be greater than or equal to the failed drive it replaces. Hot Spares Consistency Check Fault Tolerance A hot spare is an extra, unused disk drive that is part of the disk subsystem. It is usually in standby mode, ready for service if a drive fails. Hot spares permit you to replace failed drives 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 BIOS configurator allows you to specify physical drives as hot spares. When a hot spare is needed, MegaRAID IDE automatically selects the spare and include it in the configuration. Please note that Spare drives are applicable only in arrays with redundancy, such as RAID level 1. In RAID, check consistency verifies the correctness of redundant data in an array. It also help to find disk errors. For example, in a system with a mirrored drive, checking consistency means making sure that both the member-drives of the mirror contains the same data. Fault tolerance is achieved through the use of mirroring (RAID 1.) Mirroring provides 100% redundancy. See Disk Mirroring on page 6 for more information. 8 MegaRAID IDE (ATA/66) and MegaRAID IDE 100 (ATA/100) User's Guide

19 3 RAID Levels There are six official RAID levels (RAID 0 through RAID 5). MegaRAID IDE supports RAID levels 0, 1, and 10. RAID Level Type turn to 0 Standard page 9 1 Standard page Standard page 11 RAID 0 RAID 0 provides disk striping across all drives in the RAID subsystem. RAID 0 does not provide 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 the array. The size of each block is determined by the stripe size parameter, set during the creation of the RAID set. RAID 0 offers high bandwidth. By breaking up a large file into smaller blocks, MegaRAID IDE can use multiple IDE channels and drives to read or write the file faster. RAID 0 involves no parity calculations to complicate the write operation. This makes RAID 0 ideal for applications that require high bandwidth but do not require fault tolerance. Uses Strong Points Weak Points Drives RAID 0 provides high data throughput, especially for large files. Any environment that does not require fault tolerance. Provides increased data throughput for large files. No capacity loss penalty for parity. Does not provide fault tolerance. All data lost if any drive fails. One to four. Chapter 3 RAID Levels 9

20 RAID 1 Uses Strong Points Weak Points Drives RAID 1 duplicates all data from one drive to a second drive. RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity. Use RAID 1 for small databases or any other environment that requires fault tolerance but small capacity. RAID 1 provides complete data redundancy. RAID 1 is ideal for any application that requires fault tolerance and minimal capacity. RAID 1 requires twice as many disk drives. Performance is impaired during drive rebuilds. Two. 10 MegaRAID IDE (ATA/66) and MegaRAID IDE 100 (ATA/100) User's Guide

21 RAID 10 Uses Strong Points Weak Points Drives RAID 10 provides both RAID 0 (data striping) and RAID 1 (disk mirroring). It requires two sets of RAID 0 drives (total of four drives). In RAID 10, data is striped across the two arrays and duplicated from one drive to the second drive in each RAID 1 array. Use RAID 10 for small databases or any other environment that requires fault tolerance and high data throughput, especially for large files. RAID 10 provides complete data redundancy. RAID 10 is ideal for any application that requires fault tolerance and increased data throughput. RAID 10 requires a minimum of four disk drives. Performance is impaired during drive rebuilds. Four drives. Chapter 3 RAID Levels 11

31 5 Configuring MegaRAID IDE Configuring Arrays This chapter explains how to: configure MegaRAID IDE and arrays assign RAID levels plan the array configuration optimize storage use the MegaRAID IDE Setup Utility Organize the physical disk drives in arrays after the drives are connected to MegaRAID 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 fault tolerance. Use RAID 1 or mirror configuration to attain this objective. Maximizing Drive Performance You can optimize drive performance by using striping. Select RAID 0 or striping to configure an array for optimal performance.

Array Type By default an array is created in stripe mode. When you select this field, a pop-up window displays the following options: RAID MODE STRIPE MIRROR RAID 10 SPARE POOL Select the intended RAID mode by using the arrow navigation keys and pressing <Enter>. The SPARE POOL option is not a RAID mode, but a way to assign physical drive(s) as hot spare to be used in case of a mirror failure. When a mirror configured array has a drive fail, a spare drive can be used to replace the failed drive and rebuild the array. Note: Drive(s) To rebuild a drive from the SPARE POOL, the size of the physical drive in SPARE POOL must be greater than or equal to the smallest drive in the array. There is no default setting for this field. You must select the drives for the configured array. When this field is selected, a pop-up window will display all the available physical drives with check-boxes. DRIVE SELECTION BOX [ ] Cntlr 0-Primary Master [ ] Cntlr 0-Primary Slave [ ] Cntlr 0-Secondary Master [ ] Cntlr 0-Secondary Slave Use the arrow navigation keys and press the Spacebar to select or deselect the drive or drives to be part of the array. Press <Enter> when done. If you select mirror mode as the array type, you must select two drives to be in the array. This pop-up window will appear only when configuring RAID 0 (Stripe) and RAID 1 (Mirror) arrays. A RAID 10 array contains drives in each Stripe of the array and only two drives are allowed in each stripe. The maximum amount of Stripes is limited to four Stripes.

STRIPE 32 KB 64 KB 128 KB 256 KB 512 KB 1024 KB 2048 KB 4096 KB Note: Bootable You cannot change the stripe size of an array that has already been configured. This determines which of the configured arrays should be used for booting the system when MegaRAID IDE is selected as the boot device. The options are Yes or No. BOOT OPTION YES NO You can select the boot device from the system BIOS setup. Only one array is allowed to be bootable in a system. Drive Size Build Array Note: 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 total drive capacity. The Build Array option is valid for RAID 1 (Mirror) and RAID 10 arrays only. It is used to rebuild the array using a drive from the SPARE POOL. When Build Array starts, it will prompt the user to select the target drive. It does this because both drives can be still online. Once the target drive is selected, the rebuild will start. A drive Rebuild can take a long time depending on the size of the drive. A 2 GB (UDMA 5) 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 to the array you want to delete and then press <F5>. Caution Use this option with caution.

39 Initialization (F8) (CNTRL-M) This procedure initializes a logical drive to prepare it for the installation of an operating system. The initialization deletes (writes 0 to) the initial 100 MB of the logical drive created. Initialization is the process of writing zeros to the data fields of a logical drive and, in fault-tolerant RAID levels, generating the corresponding parity to put the logical drive in a Ready state. Initializing erases previous data and generates parity so that the logical drive will pass a consistency check. Arrays will work without initializing, but they can fail a consistency check because the parity fields have not been generated. Save and Exit (F10) When you have completed the array configuration, press <F10> to save the configuration and exit. If you do not want to save the configuration or any changes that you have made, press <Esc>. Subsequent message boxes display for confirmation; respond to them appropriately.
