Set Factory
Defaults
Use this option to load the default MegaRAID ® WebBIOS CU settings.
The default is No.
Cluster Mode
Use this option to enable or disable Cluster mode. The default is
Disabled. A cluster is a grouping of independent servers that can
access the same data storage and provide services to a common set
of clients. When Cluster mode is disabled, the system operates in
Standard mode.
Rebuild Rate
Use this option to select the rebuild rate for drives connected to the
selected controller. The default is 30 percent. The rebuild rate is the
percentage of system resources dedicated to rebuilding a failed drive.
The higher the number, the more system resources devoted to a
rebuild.
BGI Rate
Use this option to select the amount of system resources dedicated
to background initialization of virtual drives connected to the selected
controller. The default is 30 percent.
CC Rate
Use this option to select the amount of system resources dedicated
to consistency checks of virtual drives connected to the selected
contrroller. The default is 30 percent.
Reconstruction
Rate
Use this option to select the amount of system resources dedicated
to reconstruction of drives connected to the selected controller. The
default is 30 percent.
NCQ
Native Command Queuing (NCQ) gives an individual drive the ability to
optimize the order in which it executes the read and write commands.
The default is Enabled.
Coercion Mode
Drive coercion is a tool for forcing drives of varying capacities to the
same size so they can be used in a drive group. The coercion mode
options are None, 128MB-way, and 1GB-way. The default is 1GB-way.
The number you choose depends on how much the
drives from various vendors vary in their actual size. We
recommend that you use the 1GB coercion mode option.
S.M.A.R.T.
Polling
This option determines how frequently the controller polls for drives
reporting a predictive drive failure (S.M.A.R.T. error). The default is 300
seconds (5 minutes).
Alarm Control
Select this option to enable, disable, or silence the onboard alarm tone
generator on the controller. The default is Enabled.
