Synchronize Array
The Synchronize Array menu allows the user to synchronize the data on each drive. Synchronization is a maintenance
procedure for fault tolerant arrays (RAID 1, 0+1, 3, 5, 30, and 50) 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
.
Array ID: 1
Only existing Array IDs are Displayed.
Array ID: 2
Press or

Important
Promise Technology suggests synchronizing an array once a month.
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).
Rebuild/Sync Priority
This function assigns the amount of importance to rebuilding/synchronizing data in the background. A
High
setting
assigns most of the unit’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 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.

Smart Check
SMART is Self-Monitoring Analysis and Reporting Technology, a function of the disk drives that gathers performance
information used to predict a pending drive failure. With this option enabled, the Controller will check the status of the disk
drives and report any problems
.
Under most conditions, there will be no apparent difference in array performance with
Smart Check
enabled.
