1, 0+1, 3 and 5) to maintain data consistency on all drives. To synchronize the
array, go to the Configuration menu and select Configure Array; then select
Advance Features and choose Synchronize Array.

Synchronization is a preventative maintenance measure used to avoid problems
with data integrity. Synchronizing simply recalculates redundant data (similar to
the rebuild process) and matches the data on the drive(s).

Assigns the amount of importance that UltraTrak100 gives to
rebuilding/synchronizing data in the background. A High setting assigns most of
UltraTrak100’s resources to the rebuild process at the expense of responding to
ongoing read/write data requests by the operating system. A Low setting gives
priority to ongoing read/write data requests by the operating system at the
expense of the rebuild/synchronization process and will typically result in longer
rebuild/synchronization times. The default setting is High. To set the Rebuild/Sync
priority, go to the Configuration menu and select Configure Array; then select
Advance Features and choose Rebuild/Sync Pri.
