  • Page 80: How Raid Works

    RAID RAID Overview This chapter gives an overview of RAID storage system within the context of recommended setting of ExaSAN based SAN environment to provide fast, shared storage to client computers. 5.1 How RAID Works RAID, or Redundant Array of Independent Disks, is a data-storage technology that spreads data across multiple drives.

  • Page 81: Data Parity

    RAID synchronized; that is, anything written to one disk is also written to the other. Mirrored data is very secure because if one disk fails, the data is available from the other disk. 5.2.3 Data Parity The controller can generate “parity” for the ability to protect and rebuild data. Parity protects stored information without requiring data mirroring.

  • Page 82: Raid 0+1: Striped Set With Mirroring

    RAID RAID 6 is no more space inefficient than RAID 5 with a hot spare drive when used with a small number of drives, but as arrays become bigger and have more drives the loss in storage capacity becomes less important and the probability of data loss is greater. RAID 6 provides protection against data loss during an array rebuild, when a second drive is lost, a bad block read is encountered, or when a human operator accidentally removes and replaces the wrong disk drive when attempting to replace a failed drive.
  • Page 83 Appendices Appendices User Guide Page 1...
  • Page 84 Appendices Appendix A: FAQs 1. Q: Why is my disk LED status RED? A: This is likely caused by a faulty hard drive. Replace the faulty drive as soon as possible to protect your data. 2. Q: After an array has been created in RAIDGuard X, but the host does not find the array volume.
  • Page 85 10. Q: When inserting the HDD into my A12S2-PS, why does RAIDGuard X show the HDD mode as Lock? A: The lock indicates that the HDD has been previous used in Accusys products and that it contains a portion of a RAID data. If the data can be deleted, you can unlock the HDD.
