  • Page 9: Introduction To The 3Ware Command Line Interface

    If a command is labeled as applying to the SX controller, it is available for both 9550SX and 9550SXU. Important! For all of the functions of the 3ware CLI to work properly, you must have the proper CLI, firmware, and driver versions installed. Check http://www.3ware.com/support for the latest versions and upgrade instructions.

  • Page 10: Features Of The Cli

    For a summary of what you can do using the CLI, see “Common Tasks Mapped to CLI Commands” on page 20. Supported Operating Systems The 9.5.1 version of the 3ware CLI is supported under the following operating systems: • Windows®. Windows XP, Windows Server 2003, Windows Server 2008, and Vista, (32-bit and 64-bit versions of each).

  • Page 16: Conventions

    Understanding RAID Levels and Concepts 3ware RAID controllers use RAID (Redundant Array of Inexpensive Disks) to increase your storage system’s performance and provide fault tolerance (protection against data loss).

  • Page 17: Raid Concepts

    When working with a 3ware RAID controller, “unit” is the term used to refer to an array of disks that is configured and managed through the 3ware software.

  • Page 18: Available Raid Configurations

    RAID levels 0, 1, 10 and 5 are the most popular. AMCC's 3ware controllers support RAID 0, 1, 5, 6, 10, 50, and Single Disk. The information below provides a more in-depth explanation of the different RAID levels.
  • Page 19 Fault tolerance is a basic requirement for critical systems like web and database servers. 3ware uses a patented technology, TwinStor®, on RAID 1 arrays for improved performance during sequential read operations. With TwinStor technology, read performance is twice the speed of a single drive during sequential read operation.
  • Page 20 For example, one sub-unit can be degraded, while another may be rebuilding, or one sub-unit may be initializing, while another is verifying. AMCC 3ware’s implementation of RAID 6 requires a minimum of five drives. Performance and storage efficiency also increase as the number of drives increase.
  • Page 21 (half of each mirrored pair) and the array will continue to function. Please note that if both halves of a mirrored pair in the RAID 10 array fail, then all of the data will be lost. www.3ware.com...
  • Page 22 Chapter 1. Introduction to the 3ware Command Line Interface Figure 5. RAID 10 Configuration Example RAID 50 RAID 50 is a combination of RAID 5 with RAID 0. This array type provides fault tolerance and high performance. RAID 50 requires a minimum of six drives.
  • Page 23 Figure 6. RAID 50 Configuration Example Single Disk A single drive can be configured as a unit through 3ware software. (3BM, 3DM 2, or CLI). Like disks in other RAID configurations, single disks contain 3ware Disk Control Block (DCB) information and are seen by the OS as available units.

  • Page 24: Determining What Raid Level To Use

    Chapter 1. Introduction to the 3ware Command Line Interface Hot Spare A hot spare is a single drive, available online, so that a redundant unit can be automatically rebuilt in case of drive failure. Determining What RAID Level to Use Your choice of which type of RAID unit (array) to create will depend on your needs.

  • Page 26: Support For Over 2 Terabytes

    Chapter 1. Introduction to the 3ware Command Line Interface Through drive coercion, the capacity used for each drive is rounded down so that drives from differing manufacturers are more likely to be able to be used as spares for each other. The capacity used for each drive is rounded down to the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded down to the nearest 5 GB for drives over 45 GB.
