System Requirements

ACSLS includes the following system requirements:

  • Memory: 4GB minimum

    To show system memory:

    • Solaris

      prtconf | grep Mem

    • Linux

      grep MemTotal /proc/meminfo

  • Swap Space: Solaris and Linux systems should be equipped with a minimum of 4GB of memory and a minimum of 2GB of swap space. When system memory exceeds 6GB, provide swap space that is no less than 30% of physical memory. To check swap space, enter one of the following operating system commands:
    • Solaris

      vmstat -S

      The result is expressed in kilobytes.

    • Linux

      vmstat -s | grep total

      The result is expressed in kilobytes.

  • File systems and required databases:

    ACSLS enables you to install in any file system. You must define the following directories before installing ACSLS:

    • A base directory where the ACSLS components will be installed.
    • A default directory for ACSLS backups. It is recommended (but not required) to place the ACSLS backup directory in a separate file system from the ACSLS base directory.

    Although you can install ACSLS in any directory, the default directories used for ACSLS are:

    • /export/home is the default ACSLS base directory.
    • /export/backup is the default ACSLS backup directory.

    The ACSLS base directory file system requires a minimum of 5GB free. Reserve an additional 5GB free for ACSLS backups. To view file system sizes, enter the following command:

    df -h

  • Fibre card (optional) is optional. A suitable HBA is required for Fibre Channel operations.
    • For target mode operation, supporting the Logical Library feature, this HBA must be a contemporary QLogic fibre card (4Gb or higher).
    • For initiator mode operation, supporting a fibre-connected library such as the SL500 or SL150, ACSLS is fully tested and certified with QLogic and Emulex HBAs.
