6.2 Accessing Controller Configuration
Options
To be able to access controller configuration options either use the RAID View toolbar icon or select
the
RAID View command from the Open menu to open the RAID View. Once the RAID View has
been opened select the Configuration button from the content window. For more information on
accessing the controller configuration options, please refer to section 4.6, ”Using the RAID View
Window”, on page 58.
The following is a complete list of configuration controls and information displays that users will
have available once the Controller Configuration option has been selected.
More information about many of these variables is available in the controller hardware and
firmware documentation.
6.3 Caching
To be able to configure the data cache, select the “Caching” tab, as shown in Figure 6–1, from the
Configuration View Window Tabs.
The data cache can be configured for optimal I/O performance using the following variables:
• Caching Policy (choose one from Figure 6–2):
– Cache Write Back. (Default controller setting.) Recommended operating mode, provides
better performance.
– Cache Write Through. Used primarily if no cache battery backup is installed and there is
increased likelihood of a power failure.
• Optimization Policy (choose one):
Important Optimization settings should not be changed after logical drives are created. Under some
circumstances, changing the optimization setting after logical drives have been created will destroy
existing data on those drives.
