    APPENDIX In the illustration, volume 1 can be assigned a RAID level 5 of operation while volume 0 might be assigned a RAID level 1E of operation. Alternatively, the free space can be used to create vol- ume 2, which could then be set to use RAID level 5. Ease of Use Features Foreground Availability/Background Initialization •...

    APPENDIX • Online RAID Level and Stripe Size Migration For those who wish to later upgrade to any RAID capabilities, a system with online RAID level/stripe size migration allows a simplified upgrade to any supported RAID level without having to reinstall the operating system. The RAID controllers can migrate both the RAID level and stripe size of an existing volume set, while the server is online and the volume set is in use.

    APPENDIX migration is completed, the volume set transitions to degraded mode. If a global hot spare is present, then it further transitions to rebuilding state. Online Volume Expansion • Performing a volume expansion on the controller is the process of growing only the size of the latest volume. A more flexible op- tion is for the array to concatenate an additional drive into the RAID set and then expand the volumes on the fly.

    APPENDIX data previously located on the failed drive is reconstructed on the hot spare. Dedicated hot spare is assigned to serve one specified RAID set. Global hot spare is assigned to serve all RAID set on the RAID controller. Dedicated hot spare has higher priority than the global hot spare.

    APPENDIX tomatically assigned as a hot spare if any hot spare disk was used to rebuild and without new installed drive replaced it. In this condition, the Auto Declare Hot-Spare status will be disap- peared if the RAID storage has since powered off/on. The Hot-Swap function can be used to rebuild disk drives in arrays with data redundancy such as RAID level 1, 1E, 3, 5, 6, 10, 30, 50 and 60.

    APPENDIX RAID controller allows user to choose the task priority (Ultra Low (5%), Low (20%), Medium (50%), High (80%)) to balance volume set access and background tasks appropriately. For high array performance, specify an Ultra Low value. Like volume ini- tialization, after a volume rebuilds, it does not require a system reboot.

    APPENDIX and that location will be tested by the drive to be certain the location is not defective. If it is found to have a defect, data will be automatically relocated, and the defective location is mapped out to prevent future write attempts. In the event of an unrecoverable read error, the error will be reported to the host and the location will be flagged as being potentially defective.

  • Page 105: Understanding Raid

    APPENDIX Appendix F Understanding RAID RAID is an acronym for Redundant Array of Independent Disks. It is an array of multiple independent hard disk drives that provides high performance and fault tolerance. The RAID controller imple- ments several levels of the Berkeley RAID technology. An appro- priate RAID level is selected when the volume sets are defined or created.

  • Page 106: Raid 1

    APPENDIX RAID 1 RAID 1 is also known as “disk mirroring”; data written on one disk drive is simultaneously written to another disk drive. Read performance will be enhanced if the array controller can, in paral- lel, access both members of a mirrored pair. During writes, there will be a minor performance penalty when compared to writing to a single disk.

  • Page 107: Raid 10(1E)

    APPENDIX RAID 10(1E) RAID 10(1E) is a combination of RAID 0 and RAID 1, combining stripping with disk mirroring. RAID Level 10 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 then duplicated to another set of drive for data protection.

  • Page 108: 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 being 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 109: Raid 6

    APPENDIX RAID 6 RAID 6 provides the highest reliability. It is similar to RAID 5, but it performs two different parity computations or the same compu- tation on overlapping subsets of the data. RAID 6 can offer fault tolerance greater than RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data.

    APPENDIX Important RAID level 00, 100, 30, 50 and 60 can support up to eight RAID set. If volume is RAID level 00, 100, 30, 50, or 60, you can’t change the volume to another RAID level. If volume is RAID level 0, 1, 10(1E), 3, 5, or 6, you can’t change the vol- ume to RAID level 00, 100, 30, 50, or 60.
