  • 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. The RAID array appears to the host computer as a single storage unit or as multiple logical units.

  • Page 20: Raid Levels

    MegaRAID can instantly rebuild a logical drive using a hot spare. After the hot spare is automatically moved into the RAID subsystem, the failed drive can be automatically rebuilt. The RAID disk array continues to handle requests while the rebuild occurs. MegaRAID Enterprise 1600 Hardware Guide...

  • Page 21: 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. The combined storage space is composed of stripes from each drive.

  • Page 22: Disk Mirroring

    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. MegaRAID Enterprise 1600 Hardware Guide...

  • Page 23: Disk Spanning

    Disk Spanning Disk spanning allows multiple disk drives to function like one big drive. Spanning overcomes lack of disk space and simplifies storage management by combining existing resources or adding relatively inexpensive resources. For example, four 400 MB disk drives can be combined to appear to the operating system as one single 1600 MB drive.

  • Page 24: Parity

    RAID level 5 combines distributed parity with disk striping. Parity provides redundancy for one drive failure without duplicating the contents of entire disk drives, but parity generation can slow the write process. MegaRAID Enterprise 1600 Hardware Guide Description The parity of the data on two or more disk drives is stored on an additional disk.

  • Page 25: 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.

  • Page 26: Disk Rebuild

    At 100%, the rebuild has a higher priority than any other system activity. Physical Array A RAID array is a collection of physical disk drives governed by the RAID management software.

    The disk subsystem can be part of the host computer or separate from it. Enclosure management helps you stay informed of events in the disk subsystem, such as a drive or power supply failure.

  • Page 29: Raid Levels

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

    Data striping and mirrored drives. Disk striping with a dedicated parity drive. Disk striping and parity data across all drives. MegaRAID Enterprise 1600 Hardware Guide Pros Cons Maximum Physical Drives High data No fault One to 32 throughput tolerance.

  • Page 31: 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. The size of each block is determined by the stripe size parameter, set during the creation of the RAID set.

  • Page 32: Raid 1

    RAID 1 provides complete data redundancy. RAID 1 is ideal for any application that requires fault tolerance and minimal capacity. Weak Points RAID 1 requires twice as many disk drives. Performance is impaired during drive rebuilds. Drives MegaRAID Enterprise 1600 Hardware Guide...

  • Page 33: 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. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks to all but one drive in the array.
  • Page 34 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. MegaRAID Enterprise 1600 Hardware Guide...

  • Page 35: 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.

  • Page 36: Raid 10

    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. Drives Four to 32 (must be a multiple of two) MegaRAID Enterprise 1600 Hardware Guide...

  • Page 37: 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.

  • Page 38: Raid 50

  • Page 71: Scsi Termination

    SCSI Termination The SCSI bus on a SCSI channel is an electrical transmission line. It must be terminated properly to minimize reflections and losses. You complete the SCSI bus by setting termination at both ends. MegaRAID automatically provides SCSI termination at one end of the SCSI bus for each channel. Terminate the other end of the bus by attaching an external SCSI terminator module to the end of the cable for each channel or by attaching a SCSI device that internally terminates the SCSI bus at the end of each SCSI channel.
  • Page 72 Make sure J2, J3, J5, and J7 are either always open (termination always enabled), or Pins 1-2 are shorted (termination controlled by software). Note: Channels C and D have only external connectors, so termination should always be either anabled or under software control on these two channels. MegaRAID Enterprise 1600 Hardware Guide...
