Figure 3-58 iTBBU properties
Set Factory Defaults: No is the default
This loads the default configurations.
Cluster Mode: Disabled is the default
This provides additional cluster services while accessing the same data
storage. The default setting cannot be changed because it is not supported.
Rebuild Rate: 48 is the default
This is the percentage of system resources dedicated to rebuilding a failed
drive. The higher the value is, the more system resources are devoted to a
rebuild. The value can be 1-100%.
Tip: We do not recommend setting the lowest nor the highest value.
A very high percentage can effect performance negatively because this is a
background process that additionally uses the SAS subsystem.
A very low percentage can result in a loss of data, in case further hard
drives within the same RAID subset (VD) are going offline while the
Rebuild process is running.
BGI Rate: 48 is the default
This affects the amount of system resources dedicated to background
initialization (BGI) of virtual disks connected to the selected adapter. The
value can be 1-100%.
