Note:
The policy Overwrite ECC is equivalent to the "Continue on Source Error"
option in 3BM and the "IgnoreECC" option in the CLI.
(Not applicable for SAS drives) This policy enables or disables
Queuing.
Native Command Queuing (NCQ) for SATA 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 123.
Note:
If the write cache setting is disabled for a unit, the StorSave Profile capability
does not apply and is automatically disabled.
