  • Page 7: Chapter 1 Introduction

    Chapter 1 Introduction The RAID subsystem is a Ultra 320 LVD SCSI-to-Serial ATA II RAID (Redundant Arrays of Independent Disks) disk array subsystem. It consists of a RAID disk array controller and sixteen (16) disk trays. The subsystem is a “Host Independent” RAID subsystem supporting RAID levels 0, 1, 3, 5, 6 0+1 and JBOD.

  • Page 9: Raid Concepts

    1.2 RAID Concepts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive. The array of drives appears to the host computer as a single logical drive.
  • Page 10 By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives. This keeps all drives in the array busy during heavy load situations. This situation allows all drives to work concurrently on different I/O operations, and thus maximize the number of simultaneous I/O operations that can be performed by the array.
  • Page 11 , also known as disk mirroring, is simply a pair of disk drives that store RAID 1 duplicate data but appear to the computer as a single drive. Although striping is not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a single large array consisting of pairs of mirrored drives.
  • Page 12 sector-stripes data across groups of drives, but one drive in the group is RAID 3 dedicated to storing parity information. RAID 3 relies on the embedded ECC in each sector for error detection. In the case of drive failure, data recovery is accomplished by calculating the exclusive OR (XOR) of the information recorded on the remaining drives.
  • Page 13 is similar to RAID 5 in that data protection is achieved by writing parity RAID 6 information to the physical drives in the array. With RAID 6, however, two sets of parity data are used. These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives.
  • Page 14 achieves a balance between the increased data availability Dual-level RAID inherent in RAID 1 and RAID 5 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 RAID 10 and RAID 0+5 or RAID 50. In summary: RAID 0 is the fastest and most efficient array type but offers no fault- tolerance.

  • Page 15: Raid Management

    RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Description Level Drives Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. Drives are paired and mirrored.

  • Page 16: Scsi Concepts

    1.3 SCSI Concepts Before configuring the subsystem, you must first understand some basic SCSI concepts so that the subsystem and SCSI devices will function properly. 1.3.1 Multiple SCSI Format Support The subsystem support the SCSI interface standards listed below. Note that the data bit and cable length restrictions must be followed.

  • Page 17: Terminators

    1.3.3 Terminators Based on SCSI specifications, the SCSI bus must be terminated at both ends, meaning the devices that are connected to the ends of the SCSI bus must have their bus terminators enabled. Devices connected in the middle of the SCSI bus must have their terminators disabled.

  • Page 18: Array Definition

    1.4 Array Definition 1.4.1 RAID Set A RAID Set is a group of disks containing one or more volume sets. It has the following features in the RAID subsystem controller: 1. Up to sixteen RAID Sets are supported per RAID subsystem controller. 2.

  • Page 19: Easy Of Use Features

    1.4.3 Easy of Use features 1.4.3.1 Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used immediately after the creation. But the RAID 3, 5 and 6 volume sets must be initialized to generate the parity. In the Normal Initialization, the initialization proceeds as a background task, the volume set is fully accessible for system reads and writes.
  • Page 20 1.4.3.3 Online Capacity Expansion Online Capacity Expansion makes it possible to add one or more physical drive to a volume set, while the server is in operation, eliminating the need to store and restore after reconfiguring the raid set. When disks are added to a raid set, unused capacity is added to the end of the raid set.

  • Page 21: High Availability

    1.4.3.4 Online RAID Level and Stripe Size Migration User 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. Online RAID level/ stripe size migration can prove helpful during performance tuning activities as well as in the event that additional physical disks are added to the RAID subsystem.
  • Page 22 1.4.4.2 Hot-Swap Disk Drive Support The RAID subsystem has built the protection circuit to support the replace- ment of UDMA hard disk drives without having to shut down or reboot the system. The removable hard drive tray can deliver “hot swappable,” fault- tolerant RAID solutions at prices much less than the cost of conventional SCSI hard disk RAID subsystems.
