  • Page 9: Introduction To Raid

    Introduction to RAID RAID (Redundant Array of Independent Disks) is an array (group) of multiple independent hard drives that provide high performance and fault tolerance. A RAID disk subsystem improves I/O (input/output) performance and reliability. 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.

  • Page 10: Raid Overview

    These stripes are interleaved in a repeated sequential manner. The combined storage space is composed of stripes from each drive. IBM IDE supports stripe sizes of 32 KB to 4 MB.

  • Page 11: Disk Mirroring

    Disk Mirroring With mirroring (used in RAID 1), data written to one hard drive is simultaneously written to another hard drive. If one hard drive fails, the contents of the other hard 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.

  • Page 12: Disk Spanning

    The following sections explains terms associated with RAID, including: • physical drive • physical drive state • array • array state • logical drive • rebuild • hot spare • consistency check • fault tolerance IBM ATA 133 RAID Controller User's Guide...

  • Page 13: Physical Drive

    Physical Drive The physical drive is the IDE hard drive that is connected by cable to the IBM IDE card. The hard drive contains platters that are coated with material that allows them to record data magnetically. Another important feature is the read/write head, which hovers over the surface of the platter.

  • Page 14: Disk Rebuild

    IBM IDE implements automatic and transparent rebuilds using hot spare drives, providing a high degree of fault tolerance and zero downtime. The IBM IDE BIOS configurator allows you to specify physical drives as hot spares. When a hot spare is needed, IBM IDE automatically selects the spare and includes it in the configuration.

  • Page 15: Selecting A Raid Level

    Selecting a 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 the following factors: • Number of drives in the disk array •...

  • Page 17: Raid Levels

    RAID set. RAID 0 offers high bandwidth. By breaking up a large file into smaller blocks, IBM 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.

  • Page 18: Raid 1

    RAID 1 requires twice as many hard drives. Performance is impaired during drive rebuilds. Drives Figure 3-2.

  • Page 19: Raid 10

    RAID 10 RAID 10 provides both RAID 0 (data striping) and RAID 1 (disk mirroring). It requires two sets of RAID 1 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. Uses Use RAID 10 for small databases or any other environment that requires fault tolerance and high data throughput, especially for large files.

    Use the selected ATA-100/133 cables to connect up to two IDE drives (one master and one slave) to each 40-pin IDE connector on the IBM ATA 133 RAID controller. When using the extended length cables, only one drive will be connected to each channel.
  • Page 25 Note: Do not attach ATAPI drives to the IBM ATA 133 RAID controller. The controller does not support ATAPI devices, such as CD-ROM, SL120, and Zip drives. Connect only hard drives to the RAID controller and connect ATAPI devices to the IDE channels on the motherboard or to any other off-board IDE/ATAPI adapters.
