    Playback Mode In this mode, the ACU reads the contents of the specified script file and creates arrays based on the keywords specified in the script. The syntax is ACU /P <file> where file is the parameter specifying name of the script file. The file parameter can include a drive, directory, filename, and extension.

    The Command Line Interface (CLI) allows you to configure and manage controller components. The CLI contains most of the functionality offered by Adaptec Storage Manager, plus some additional functionality not offered by Adaptec Storage Manager. CLI commands allow you to automate testing or array creation in a production environment using Windows command scripts and Linux and Unix shell scripts.

  • Page 108: All Controllers

    For example, port 5 is 0:5:0; port 12 is 1:4:0. All Controllers The following terms are used in discussing the CLI: Array, container—A logical disk created from available space and made up of one or more partitions on one or more physical disks.

  • Page 145: Spanned Volume

    Spanned Volume A spanned volume is created by joining, or concatenating, two or more drives. The drives do not have to be of equal capacity and are connected end-to-end.

  • Page 146: Raid 1

    RAID 1 offers no write performance advantage over a simple volume configuration. However, because the drives share read load equally, RAID 1 provides improved read performance. An example of a RAID 1 array is shown below. RAID 1 Drive Drive Data 0 Data 0 Data 1...

  • Page 147: Raid 5

    Using parity minimizes the storage cost of redundancy. Because only one drive is used to store parity, a three-drive array, which is the worst case, uses only one-third of the total capacity for redundancy. In larger arrays, the storage cost of redundancy decreases proportionately RAID 5 write performance is limited by the need to generate parity data for every write.
