    About This Guide 3ware 9000 Series Serial ATA Controller CLI Guide provides instructions for configuring and maintaining your 3ware controller using 3ware’s command line interface (CLI). This guide assumes that you have already installed your controller in your system. If you have not yet done so, see the user guide that came with your 3ware RAID controller for instructions.

In the current CLI version, the command syntax used in previous versions of the 3ware CLI is still supported, to make sure that scripts written with the old syntax will still operate. New functions (such as BBU-related commands, StorSave and queuing policies, and other recent additions) are not available in the legacy syntax.

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

  • Page 19: Available Raid Configurations

    Provides striping, but no mirroring. Striped disk arrays achieve high transfer rates because they can read and write data on more than one drive simultaneously. The stripe size is configurable in the 3ware CLI, 3ware BIOS Manager (3BM) and in the 3ware Disk Manager (3DM 2). Requires a minimum of two drives.
  • Page 20 Fault tolerance is a basic requirement for mission 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 21 Single Disk A single drive that has been configured as a unit through 3ware software (3BM, 3DM2, 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 22: Determining What Raid Level To Use

    JBOD A JBOD is an unconfigured disk attached to your 3ware RAID controller. 3ware recommends that you use Single Disk as a replacement for JBOD, to take advantage of advanced features such as RAID level migration (RLM). JBOD units are not fault tolerant and therefore not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss.
