Optional: From the drop down menu, select either On-the-fly initialization or Performance evaluation.
On-the-fly initialization – ExaSAN RAID systems record
the initialized sectors in the bitmap. All sectors are
initialized only once. The entire initialization process will
be completed faster and the performance will be better
during the initialization.
During on-the-fly initialization, 65-75% of the full speed
(of a created RAID) is still available. You can still use the
RAID system during the RAID initialization.
Select this option (default) to ensure the completeness of
the array. If this option is selected, it will recalculate the
disk parity and data organization (how it is arranged). The
amount of time required for the initialization process varies
depending on the disk volume.
Performance evaluation – Select to evaluate the
performance of the target array. Data and parity are not
initialized. (No data protection when this mode is on).

Note
Once you click Create Array and you have selected On-the-fly initialization,
you will see the initializing % on the Main screen.
