11 1 Overview The HyperDisk IDE RAID Controller is a short PCI Adapter card that provides two IDE channels with Ultra ATA/66 (HyperDisk) or Ultra ATA/100 (HyperDisk 100) capability. HyperDisk provides a simple and cost effective way to improve the performance and reliability of your storage subsystems. HyperDisk offers high transfer rates, and faulttolerant 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 HyperDisk BIOS. The card supports the following drive modes: PIO 0-4, DMA 0-2, and Ultra DMA 0-4. In addition, it supports RAID levels 0 and 1. You can use striping (RAID 0) to improve performance or mirroring (RAID 1) to improve data security. This manual describes the HyperDisk controller. IDE Channels HyperDisk supports two IDE channels.

13 2 Introduction to RAID RAID Benefits 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 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 HyperDisk (ATA/66) and HyperDisk 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. HyperDisk supports stripe sizes of 32 KB to4mb. 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 Size 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. 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 HyperDisk (ATA/66) and HyperDisk 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 Physical Drive States The physical drive is the IDE hard disk that is connected by cable to the HyperDisk 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. A physical disk drive can be in one of these states: State Online Spare Failed Rebuilding Description 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. Chapter 2 Introduction to RAID 7

18 Array Array States 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 HyperDisk. Logical Drive Disk Rebuild A logical drive is a partition in an 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. HyperDisk 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. 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. 8 HyperDisk (ATA/66) and HyperDisk 100 (ATA/100) User's Guide

19 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. HyperDisk implements automatic and transparent rebuilds using hot spare drives, providing a high degree of fault tolerance and zero downtime. The HyperDisk BIOS configurator allows you to specify physical drives as hot spares. When a hot spare is needed, HyperDisk 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. Chapter 2 Introduction to RAID 9

21 3 RAID Levels There are six official RAID levels (RAID 0 through RAID 5). HyperDisk supports RAID levels 0 and 1. RAID Level Type turn to 0 Standard page 12 1 Standard page 13 Select RAID Level To ensure the best performance, you should select the optimal RAID level when you create a system drive. The optimal RAID level for your disk array depends on a number of factors: Selecting a RAID Level the number of drives in the disk array the capacity of the drives in the array the need for data redundancy the disk performance requirements The factors you need to consider when selecting a RAID level are listed below. Level Description and Use 0 Data divided in blocks and distributed sequentially (pure striping). Use for non-critical data that requires high performance. 1 Data duplicated on another disk (mirroring). Use for read-intensive fault-tolerant systems Pros Cons Max. Drives High data No fault One to throughput tolerance. All four for large data lost if files any drive fails. 100% data redundancy Doubles disk space. Reduced performance during rebuilds. Two or four Fault Tolerant No Yes Chapter 3 RAID Levels 11

22 RAID 0 Uses Strong Points Weak Points Drives 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, HyperDisk 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. 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. 12 HyperDisk (ATA/66) and HyperDisk 100 (ATA/100) User's Guide

23 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 drives.

33 5 Configuring HyperDisk Configuring Arrays This chapter explains how to: configure HyperDisk, arrays, and logical drives assign RAID levels plan the array configuration optimize storage use the HyperDisk Setup Utility Organize the physical disk drives in arrays after the drives are connected to HyperDisk. Each array can consist of one to four physical disk drives. HyperDisk supports up to two arrays. The number of drives in an array determines the RAID levels that can be supported. Configuration Strategies The most important factors in RAID array configuration are drive availability (fault tolerance), and drive performance. You have to choose a drive configuration that maximizes one factor at the expense of the other factor. 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. Chapter 5 Configuring HyperDisk 23

34 Assigning RAID Levels Only one RAID level can be assigned to each array. The drives required per RAID level is: RAID Level Minimum Number of Physical Drives 0 One Four 1 Two Two Maximum Number of Physical Drives Configuring Arrays After you have installed the HyperDisk controller in the system and have attached all physical disk drives, perform the following actions to prepare a RAID disk array: Step Action 1 Press <Ctrl> <M> to run the HyperDisk Manager. 2 Define and configure one or more logical drives. See page 27 for more information. 3 Create and configure one or more system drives (logical drives). Select the RAID level, cache policy, read policy, and write policy. 6 Save the configuration. 7 Initialize the system drives. After initialization, you can install the operating system. 24 HyperDisk (ATA/66) and HyperDisk 100 (ATA/100) User's Guide
