Auto-Carving. Auto-carving can be enabled or disabled by selecting the
appropriate radio button.
When this feature is enabled, any unit that is over a specified size (known as
the carve size) will be broken down into multiple volumes of that size, plus a
remainder volume. The default carve size is 2048 GB (2 TB). For example,
using the default carve size, if the unit is 2.5 TB then it will contain two
volumes, with the first volume containing 2 TB and the second volume
containing 0.5 TB. If the unit is 5.0 TB then it will contain 3 volumes, with
the first two volumes containing 2 TB each and the last volume containing
1 TB.
Carve Size. Sets a size for dividing up units into volumes when Auto-Carving
is enabled. This setting can be between 1024 and 2048 GB.
Number of Drives Per Spin-up. Number of drives that will spin up at the
same time when the controller is powered up. (This setting only applies when
the feature is supported by the disk drives.) This setting can only be changed
in the CLI.
Delay between Spin-ups. The delay time (in seconds) between drive groups
that spin up at one time on this particular controller. This setting can only be
changed in the CLI.
Export JBOD (Unconfigured) Disks. This feature is not relevant for the
Macintosh.
