    INTRODUCTION 1. Introduction This section presents a brief overview of the 12/16/24 bays external Fibre/SAS/iSCSI to 12Gb/s SAS RAID subsystem. 1.1 Overview The 12Gb/s SAS interface supports both 12Gb/s and 6Gb/s SAS/SATA drives. The controllers attach directly to SATA/SAS backplanes and can increase capacity using one additional Min SAS HD SFF-8644 external connector.

  • Page 211: Raid Concept

    APPENDIX Appendix G RAID Concept RAID Set A RAID set is a group of disk containing one or more volume sets. It has the following features in the RAID subsystem. A volume set must be created either on an existing RAID set or on a group of available individual disks (disks that are not yet a part of an RAID set).

  • Page 212: Easy Of Use Features

    APPENDIX Easy of Use Features • Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used immediately after the creation. But the RAID 3 and 5 volume sets must be initialized to generate the parity. In the Normal Initialization, the initialization proceeds as a background task, the volume set is fully accessible for system reads and writes.

  • Page 213: Online Raid Level And Stripe Size Migration

    APPENDIX The RAID subsystem redistributes the original volume set over the original and newly added disks, using the same fault-tolerance configuration. The unused capacity on the expanded RAID set can then be used to create additional volume sets, with potentially a different fault tolerance setting.

  • Page 214: High Availability

    APPENDIX High availability • Creating Hot Spares A hot spare drive is an unused online available drive, which is ready for replacing the failure disk drive. In a RAID level 1, 1E 3, 5, 6 or 10 raid set, any unused online available drive installed but not belonging to a raid set can be defined as a hot spare drive.

  • Page 215: Hot-Swap Disk Rebuild

    APPENDIX • Hot-Swap Disk Rebuild A Hot-Swap function can be used to rebuild disk drives in ar- rays with data redundancy such as RAID level 1, 10, 3, 5 and 6. 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.

  • Page 216: Raid 0

    APPENDIX • RAID 0 RAID 0, also referred to as striping, writes stripping of data across multiple disk drives instead of just one disk drive. RAID 0 does not provide any data redundancy, but does offer the best high-speed data throughput. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array.

  • Page 217: Raid 10(1E)

    APPENDIX • RAID 10(1E) RAID 10(1E) is a combination of RAID 0 and RAID 1, combing stripping with disk mirroring. RAID Level 10(1E) combines the fast performance of Level 0 with the data redundancy of Level 1. In this configuration, data is distributed across several disk drives, similar to Level 0, which are a stripe across a number of mirrored sets for data protection.

  • Page 218: Raid 5

    APPENDIX • RAID 5 RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the controllers rather than concentrated on a dedicated parity disk. If one drive in the system fails, the parity information can be used to reconstruct the data from that drive.

  • Page 219: Raid X0

    APPENDIX to avoid potential unrecoverable error during rebuild. • RAID x0 RAID level-x0 refers to RAID level 30, 50 and 60. RAID x0 is a combination multiple RAID x volume sets with RAID 0 (striping). Striping helps to increase capacity and perfor- mance without adding disks to each RAID x array.

  • Page 220: Jbod

    APPENDIX Important RAID level 30, 50 and 60 can support up to eight sub- Volumes (RAID set). If the volume is RAID level 30, 50, or 60, you cannot change the volume to another RAID level. If the volume is RAID level 0, 1, 10, 3, 5, or 6, you cannot change the volume to RAID level 30, 50, or 60.
