Setting the StorSave Profile for a Unit | AMCC 720-0138-00 instruction

Chapter 5. Configuring Units

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

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

2In 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.

Setting the StorSave Profile for a Unit

You can set the desired level of data protection versus performance for a unit by selecting the StorSave Profile. Three profiles are provided: Protection (maximum data protection), Performance (maximum performance, less data protection), and Balanced (a middle ground).The default is Protection.

About StorSave Profile Levels

The three profiles automatically adjust several different factors that affect protection and performance on a per unit basis. These are summarized in the table below and further explained after the table.
