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.
 
Note: Not all drives support NCQ. If a drive does not support NCQ, the policy setting for the controller is ignored.
To enable or disable queuing for a unit through 3DM
1
Choose Management > Controller Settings from the menu bar in 3DM.
2
In the Unit Policies section of the Controller Settings page, enable queuing by checking the box under “Queuing” for the designated unit; disable it by unchecking the box.
The page refreshes, and a message at the top confirms the change that you have made.
