Enabling and Disabling Queuing for a Unit
Some drives support NCQ (Native Command Queuing), a feature that can
result in increased performance for applications that require a lot of random
access of data (usually server-type applications). This is accomplished by
causing command reordering to be done on the drive.
In order to make use of NCQ, the feature must be enabled at both the drive
and the controller. You can enable support for NCQ on a per-unit basis, as
described below.
You can see whether NCQ is supported and enabled for a particular drive in
the Drive Details window. For details, see “Drive Details window” on
page 193.
Note:
Not all drives support NCQ. If a drive does not support NCQ, the policy
setting for the controller is ignored.
