Enabling and Disabling Queuing for a Unit

Some drives support 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 command queuing, the feature must be enabled at both the drive and the controller. You can enable support for command queuing on a per-unit basis, as described below.


	Note: Not all drives support command queuing. If a drive does not support command queuing, the policy setting for the controller is ignored. Queuing information for SAS is not available.

1	Choose Management >> Controller Settings from the menu bar in 3DM2.

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.
