MODULE
       sys

SYNTAX
       Configure the datastor component within the sys module using the syntax
       in the following sections.

   MODIFY
	modify datastor
	  options:
	    dedup-cache-weight [integer]
	    description [string]
	    disk [disabled | enabled]
	    high-water-mark [integer]
	    low-water-mark [integer]
	    web-cache-weight [integer]

   DISPLAY
	list datastor
	show running-config datastor
	  options:
	    all-properties
	    cache-size
	    non-default-properties
	    one-line
	    store-size

DESCRIPTION
       You can use the datastor component to configure disk I/O operations and
       optimized page cache for frequently accessed sectors. Note that
       symmetric data deduplication is one consumer of this storage space.

EXAMPLES
	    list datastor all-properties

	    Displays the data storage settings.

	    modify datastor disk disabled

	    Disables data storage on the disk.

OPTIONS
       cache-size
	    Displays the size of the data storage in megabytes (MB).

       dedup-cache-weight
	    Specifies the relative weight of the dedup cache for the
	    Acceleration Manager module. The default value is 10.

       description
	    User defined description.

       disk Enables or disables the use of the disk (in addition to memory)
	    for data storage.

	    If you enable or disable data storage on the disk, you must then
	    restart the datastor service from the command line using the
	    command sequence bigstart restart datastor.

       high-water-mark
	    Specifies the percentage of full cache above which pruning starts.
	    The valid range is 60 - 100 percent. The default value is 92.

       low-water-mark
	    Specifies the percentage of full cache below which pruning stops.
	    The valid range is 10 - 90 percent. The default value is 80.

       store-size
	    Displays the amount of space for each disk path specified.

       web-cache-weight
	    Specifies the relative weight of the web cache for the
	    Acceleration Manager module. The default value is 10.
