  • Page 12: Raid Concepts

    Fibre to SAS/SATA RAID Subsystem 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 13 Fibre to SAS/SATA RAID Subsystem Definition of RAID Levels RAID 0 is typically defined as a group of striped disk drives without parity or data redundancy. RAID 0 arrays can be configured with large stripes for multi-user environments or small stripes for single-user systems that access long sequential records.
  • Page 14 Fibre to SAS/SATA RAID Subsystem RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated for 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 15 Fibre to SAS/SATA RAID Subsystem RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity 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 16: Raid Management

    Fibre to SAS/SATA RAID Subsystem RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Level Description Min. Drives Block striping is provide, which yields higher performance than with individual drives. There is no redundancy.

  • Page 17: Fibre Functions

    Fibre to SAS/SATA RAID Subsystem 1.3 Fibre Functions 1.3.1 Overview Fibre Channel is a set of standards under the auspices of ANSI (American National Standards Institute). Fibre Channel combines the best features from SCSI bus and IP protocols into a single standard interface, including high-performance data transfer (up to 800 MB per second), low error rates, multiple connection topologies, scalability, and more.
  • Page 18 Fibre to SAS/SATA RAID Subsystem interface. The point-to-point topology extends SCSI connectivity from a server to a peripheral device over longer distances. Arbitrated Loop The arbitrated loop (FC-AL) topology provides a relatively simple method of connecting and sharing resources. This topology allows up to 126 devices or nodes in a single, continuous loop or ring.

    Fibre to SAS/SATA RAID Subsystem 1.3.3 Basic Elements The following elements are the connectivity of storages and Server components using the Fibre channel technology. Cables and connectors There are different types of cables of varies lengths for use in a Fibre Channel configuration.

  • Page 20: Array Definition

    Fibre to SAS/SATA RAID Subsystem 1.4 Array Definition 1.4.1 Raid Set A Raid Set is a group of disk drives containing one or more logical volumes called Volume Sets. It is not possible to have multiple Raid Sets on the same disk drives. A Volume Set must be created either on an existing Raid Set or on a group of available individual disk drives (disk drives that are not yet a part of a Raid Set).

  • Page 21: High Availability

    Fibre to SAS/SATA RAID Subsystem 1.5 High Availability 1.5.1 Creating Hot Spares A hot spare drive is an unused online available drive, which is ready to replace a failed disk drive. In a RAID level 1, 10, 3, 5, 6, 30, 50, or 60 Raid Set, any unused online available drive installed but not belonging to a Raid Set can be defined as a hot spare drive.
