Setting Unit Policies
The following polices are set when you create a unit, and can be adjusted later
through settings on the
Management >> Controller Settings pages of 3DM2
and the Policy Control screen in 3BM. Details about adjusting each policy are
described on the following pages.
•
Write Cache. Determines whether write cache is enabled for the unit.
When the write cache is enabled, data is stored locally on the controller
before it is written to disk, allowing the computer to continue with its next
task. This provides the most efficient access times for your computer
system. When disabled, the computer will wait for the controller to write
all the data to disk before going on to its next task. For details, see
“Enabling and Disabling the Unit Write Cache” on page 102.
This feature interacts with functionality of the BBU, if you have one, and
with the unit’s StorSave profile. For details, see “Enabling and Disabling
the Unit Write Cache” on page 102.
•
Read Cache. Determines whether Intelligent or Basic Read Cache is
enabled, or whether Read Cache is disabled. Setting the appropriate type
of Read Cache can improve performance for different types of
applications. For details, see “Working with Read Cache Settings” on
page 104.
•
Auto-Verify. Determines whether the unit will be automatically verified at
a time determined by the Verify Schedule. Enabling this feature helps
insure that the unit is verified on a regular basis. For details, see
“Enabling or Disabling Auto-Verify for a Unit” on page 107.
