The Array Accelerator, with backup batteries, is located on a removable
daughter board. This allows any data cached there to be moved to another
SMART-2 Controller for permanent storage if necessary. Thus data that
happened to be in the write cache in the unlikely event of a SMART-2
Controller failure can be recovered.
Automatic Performance Tuning
The SMART-2 Controller has the ability to adjust or tune its performance
without manual intervention. For example, if caching is enabled but the
SMART-2 Controller determines that it is no longer beneficial, caching will
automatically be disabled. Or, if write or read-ahead caching would improve
performance but it has been automatically disabled, SMART-2 Controller will
automatically enable it again.
