    Appendix B Battery Backup Module (ARC-6120BA-T021) ARC-8050T2 RAID storage operates using cache memory. The Bat- tery Backup Module is an add-on module that provides power to the RAID storage cache memory in the event of a power failure. The BBM monitors the write back cache on the RAID storage, and provides power to the cache memory if it contains data not yet written to the hard drives when power failure occurs.

  • Page 94: Installation

    APPENDIX B-3 Installation 1. Make sure all power to the RAID storage is disconnected. 2. Install the “six eaves copper pillars” on the three mounting position (NH1, NH2 and NH3) and secures it using round head screws. 3. Connector J1 is available for the optional battery backup module.
  • Page 95 APPENDIX B-4 Battery Backup Capacity Battery backup capacity is defined as the maximum duration of a power failure for which data in the cache memory can be maintained by the battery. The BBM’s backup capacity duration can retain the cache content for a limited interval (typically 72 hours).

    APPENDIX Appendix C SNMP Operation & Installation C-1 Overview McRAID storage manager includes a firmware-embedded Simple Network Management Protocol (SNMP) agent and SNMP Extension Agent for the Areca RAID controller.

  • Page 106: Raid Concept

    APPENDIX Appendix E RAID Concept RAID Set A RAID set is a group of disks connected to a RAID controller. A RAID set contains one or more volume sets. The RAID set itself does not define the RAID level (0, 1, 1E, 3, 5, 6, 10, 30, 50 60, etc);...

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 •...

  • Page 109: Online Raid Level And Stripe Size Migration

    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 on- line and the volume set is in use.

    APPENDIX transitions from migrating state to (migrating+degraded) state. When the migration is completed, the volume set tran- sitions 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 pro- cess of growing only the size of the latest volume.

    APPENDIX is not a member of any RAID set. If a disk drive used in a volume set fails, then the hot spare will automatically take its place and he data previously located on the failed drive is reconstructed on the hot spare. Dedicated hot spare is assigned to serve one specified RAID set.

  • Page 112: Auto Rebuilding

    APPENDIX In the normal status, the newly installed drive will be recon- figured an online free disk. But, the newly-installed drive is automatically assigned as a hot spare if any hot spare disk was used to rebuild and without new installed drive replaced it.

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

  • Page 116: 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 117: 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 118: 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 119: 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 120: 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.

If volume is RAID level 0, 1, 10(1E), 3, 5, or 6, you can’t change the volume to RAID level 00, 100, 30, 50, or 60.
