    RAID Overview 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 98: Data Parity

    RAID Overview 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 99: Raid 0+1: Striped Set With Mirroring

    RAID Overview 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.

    Appendices Appendix A: FAQs 1. Q: What is the different of SW16 and SWF16? A: SW16 is the pure PCIe 2.0 switch of ExaSAN switch series. SWF16 is a three-in-one PCIe 2.0 switch. It includes MDC, SANit (SAN management software) and PCIe 2.0 switch.
  • Page 102 Appendices A: If the performance is unsteady or not achieving the expected level, in many cases, the HDD is the cause. Since the B08S2-PS is a highly efficient product, there is extreme demand placed on each HDD. As a result, it is strongly recommended to use the newest enterprise level HDD.
  • Page 103 11. Q: When inserting the HDD into my B08S2-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.
