  • Page 19: Introduction To Raid

    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 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.

  • Page 21: Adac Ultra2 S466 - Host-Based Raid Solution

    ADAC Ultra2 S466 – Host-Based RAID Solution RAID products are either: host-based or SCSI-to-SCSI. The ADAC Ultra2 S466 controller is a host-based RAID solution. ADAC Ultra2 S466 is a PCI adapter card that is installed in any available PCI expansion slot in a host system.

  • Page 22: Raid Overview

    ADAC Ultra2 S466 instantly plugs into the system when an active drive fails. After the hot spare is automatically moved into the RAID subsystem, the failed drive is automatically rebuilt. The RAID disk array continues to handle request while the rebuild occurs. ADAC Ultra2 S466 Hardware Guide...

  • Page 23: Disk Striping

    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 from 2 KB to 128 KB. These stripes are interleaved in a repeated sequential manner.

  • Page 24: Disk Spanning

    Spanning two contiguous RAID 0 logical drives does not produce a new RAID level or add fault tolerance. It does increase the size of the logical volume and improves performance by doubling the number of spindles. ADAC Ultra2 S466 Hardware Guide...

  • Page 25: Disk Mirroring

    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.

  • Page 26: Parity

    Parity provides redundancy for one drive failure without duplicating the contents of entire disk drives, but parity generation can slow the write process. A dedicated parity scheme during normal read/write operations is shown below: ADAC Ultra2 S466 Hardware Guide...

  • Page 27: Hot Spares

    Hot Spares 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. ADAC Ultra2 S466 implements automatic and transparent rebuilds using hot spare drives, providing a high degree of fault tolerance and zero downtime.

A logical drive can consist of any of the following: an entire physical array, more than one entire physical array, a part of an array, parts of more than one array, or...

  • Page 33: Raid Levels

    There are six official RAID levels (RAID 0 through RAID 5). ADAC Ultra2 S466 supports RAID levels 0, 1, 3, and 5. Gateway has designed three additional RAID levels (10, 30, and 50) that provide additional benefits. The RAID levels that ADAC Ultra2 S466 supports are:...

  • Page 35: Raid 0

    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.

  • Page 37: Raid 3

    RAID 3 RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. The stripe size must be 64 KB if RAID 3 is used. RAID 3 handles data at the block level, not the byte level, so it is ideal for networks that often handle very large files, such as graphic images.
  • Page 38 But this is not possible in RAID 3, since the writes must take turns accessing the fixed parity drive. For this reason, RAID 5 is the clear choice in this scenario. ADAC Ultra2 S466 Hardware Guide...

  • Page 39: Raid 5

    RAID 5 RAID 5 includes disk striping at the byte level and parity. In RAID 5, the parity information is written to several drives. RAID 5 is best suited for networks that perform a lot of small I/O transactions simultaneously. RAID 5 addresses the bottleneck issue for random I/O operations.

    RAID 10 provides both high data transfer rates and Strong Points complete data redundancy. RAID 10 requires twice as many drives as all other RAID Weak Points levels except RAID 1. 2n, where n is greater than 1. Drives ADAC Ultra2 S466 Hardware Guide...

  • Page 41: Raid 30

    RAID 30 RAID 30 is a combination of RAID 0 and RAID 3. RAID 30 provides high data transfer speeds and high data reliability. RAID 30 is best implemented on two RAID 3 disk arrays with data striped across both disk arrays. RAID 30 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 3 raid set.
