Controller Settings Screen
The Controller Settings screen contains three configuration elements:
■ Operating System
■ Rebuild Priority
■ Accelerator Ratio
If you have installed and configured your operating system with SmartStart or
manufacturer software, the current operating system is shown in the Operating
System frame. Use the pull-down menu to load a different operating system.
Select your rebuild priority with the High, Medium, and Low buttons.
Rebuild Priority selections have no impact on an idle system but will affect
performance on a busy system.
The Rebuild Priority affects the amount of time the controller spends
rebuilding data after a failed drive has been replaced. Select High if rebuilding
data should take precedence over handling requests from the operating system.
Select Low if the controller should rebuild data only when it is idle.
The Accelerator Ratio frame displays the amount of read-and-write cache
available on the controller. The Integrated Smart Array Controller contains
read cache space only. The ratio shown will always be 100% read to 0% write.
