• Smallest usable spare.
• Smallest usable unconfigured (available) drive.
• Smallest usable failed drive.
For additional information, see “Setting the Auto Rebuild Policy” on page 85.
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
1TB. If a specific Boot Volume was also specified in 3BM, the first volume
will be the size specified for the Boot Volume, and then the carve size will be
applied to the remainder of the unit.
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.)
Delay between Spin-ups. The delay time (in seconds) between drive groups
that spin up at one time on this particular controller.
Export JBOD (Unconfigured) Disks. Indicates whether unconfigured disks
(JBODs) should be exported to the operating system. By default, this setting
is disabled
and JBOD drives are not exported to the operating system. For
more information about this feature, see “Setting the Auto Rebuild Policy” on
page 85.
For additional information, see “Setting the Auto Rebuild Policy” on page 85.
Update Firmware
The Update Firmware function allows you to update the firmware of your
3ware RAID controller to the latest version. This keeps the firmware
compatible with updates to your operating system and allows you to take
advantage of new features 3ware may have added to your controller’s
functionality.
For additional information, see “Updating the Firmware Through 3DM 2” on
page 166.
