Software Operation Manual Chapter 1. INTRODUCTION This chapter provides a brief introduction of RAID Concept and Understanding RAID. 11..11 R RA AIID DC Coonncceepptt 1.1.1 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).
Chapter 1. Introduction 1.1.3 Foreground Availability/Background Initialization RAID 0 and RAID 1 volume sets can be used immediately after creation because they do not create parity data. However, RAID 3, 5, 6, 30, 50 or 60 volume sets must be initialized to generate parity information. In Background Initialization, the initialization proceeds as a background task, and the volume set is fully accessible for system reads and writes.
Software Operation Manual The RAID subsystem controller 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 an additional volume set, with a different fault tolerance setting if user needs to change.
Chapter 1. Introduction replaces. The host spare function only works with RAID level 1, 1E, 3, 5, 6, 10, 30, 50, or 60 volume set. The “Create Hot Spare” option gives you the ability to define a global / dedicated hot spare disk drive. To effectively use the hot spare feature, you must always maintain at least one drive that is marked as a global hot spare. Note The hot spare must have at least the same capacity as the drive it replaces. 1.1.
Software Operation Manual 11..22 U Unnddeerrssttaannddiinngg R RA AIID D RAID is an acronym for Redundant Array of Independent Disks. It is an array of multiple independent hard disk drives that provide high performance and fault tolerance. The RAID subsystem controller implements several levels of the Berkeley RAID technology. An appropriate RAID level is selected when the volume sets are defined or created.
Chapter 1. Introduction 1.2.2 RAID 1 RAID 1 also known as “disk mirroring”, data written to one disk drive is simultaneously written to another disk drive. Read performance may be enhanced if the array controller can parallel accesses both members of a mirrored pair. During writes, there will be a minor performance penalty when compared to writing to a single disk. If one drive fails, all data (and software applications) are preserved on the other drive.
Software Operation Manual 1.2.4 RAID 3 RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks to all but one drive in the array. The parity data created during the exclusive-or is then written to the last drive in the array.
Chapter 1. Introduction 1.2.5 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. All drives in the array system can be used for seek operations at the same time, greatly increasing the performance of the RAID system.
Software Operation Manual 1.2.7 RAID x0 RAID level-x0 refers to RAID level 00,100, 30, 50 and 60. RAID x0 is a combination multiple RAID x volume sets with RAID 0 (striping). Striping helps to increase capacity and performance without adding disks to each RAID x array. The operating system uses the spanned volume in the same way as a regular volume. Up to one drive in each sub-volume (RAID 3 or 5) may fail without loss of data. Up to two drives in each sub-volume (RAID 6) may fail without loss of data.
Chapter 1. Introduction Note 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 volume to RAID level 00, 100, 30, 50, or 60. 1.2.8 JBOD (Just a Bunch Of Disks) A group of hard disks in a RAID subsystem are not set up as any type of RAID configuration. All drives are available to the operating system as an individual disk.
Software Operation Manual Also known Bit-Interleaved Parity. 3 Data and parity information is subdivided and distributed across all disk. Parity must be the equal to the smallest disk capacity in the array. Parity information normally stored on a dedicated parity disk. 3 * Higher than a single drive. Also known Block-Interleaved Distributed Parity. 5 6 Data and parity information is subdivided and distributed across all disk. Parity must be the equal to the smallest disk capacity in the array.
Chapter 2. Configuration Methods Chapter 2. Configuration Methods 22..11 O Ovveerrvviieew w After the hardware installation, the SAS/SATA disk drives installed to the RAID subsystem must be configured and the volume set units initialized before they are ready to use.
