Check
Pointing
Click the On or Off button to enable or disable the Check Pointing feature. When
Check Pointing is enabled, restoring data is very fast after an unexpected power
loss, although normal performance may be slightly reduced. When Check Pointing
is disabled, normal performance is improved, but restores can take a long time to
complete. This selection is only available when the selected RAID configuration is
Mirrored, Mirrored Striped or Parity RAID, and the “Advanced RAID Features”
checkbox in the Configuration/Advanced Options dialog is checked.
Parity
Click the On or Off button to enable or disable the ability to return “dirty” data after
an unexpected power loss and all of the data could not be written to disk, rather
than taking the volume off-line. This selection is only available when the selected
RAID configuration is Parity RAID and the “Advanced RAID Features” checkbox in
the Configuration/Advanced Options dialog is checked.
Devices
Select the RAID member devices from the available device segment grid. Up to five
members can be selected for Contiguous, Concatenated, Mirrored, Striped or
Parity RAID modes (although Mirrored RAID Groups will typically contain only two
members). Exactly four members must be selected for Mirrored Striped mode.
