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.

Note: If the write cache setting is disabled for a unit, the StorSave Profile capability does not apply and is automatically disabled.

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.
