Controller Settings page
www.3ware.com 197
Queuing. This policy enables or disables Native Command Queuing (NCQ)
for drives in the unit. By default, queuing is disabled. You can enable it, if
desired.
NCQ only operates when the feature is enabled at both the drive and the
controller. If a drive does not support NCQ, the policy setting for the
controller is ignored.
Enabling NCQ can improve performance in many applications; it causes
command reordering to be done on the drive itself.
StorSave Profile. The StorSave feature includes an option that lets you
change the StorSave Profile used for a unit. Three profiles are available:
Protection, Balanced, and Performance. These profiles automatically adjust
several different factors that affect protection and performance, including
whether FUA (Forced Unit Access) is honored, whether Write Journaling is
enabled, and whether Disable Cache on Degrade is enabled. For additional
information, see “Setting the StorSave Profile for a Unit” on page 112.
Unit Names
Units can be assigned names. A name can be assigned when the unit is created
and can be changed from this screen. For additional information, see “Naming
a Unit” on page 105.
Other Controller Settings
The Other Controller settings displays information about additional settings,
some of which can only be changed in the BIOS (3BM).
Auto Rebuild. The Auto Rebuild policy determines how the controller
firmware will attempt to rebuild degraded units.
When Auto Rebuild is disabled, only spares will be used to automatically
rebuild degraded units. When Auto Rebuild is enabled, the firmware will
automatically select drives to use for rebuilding a degraded unit using the
following priority order.
Note: The policy Continue on Source Error During Rebuild is equivalent to the
“Force continue on source errors” option in 3DM v 1.x and the “ignoreEcc” option in
the CLI.
Note: If the write cache setting is disabled for a unit, the StorSave Profile capability
does not apply and is automatically disabled.
