The Storage Options page lets you define the following:
•
Idle Drive Spin Down: Configure the NSS to spin down the disk drives after
a predefined time of inactivity. Select the period of time that the disk drive
must be idle before it is spun down.
•
RAID Rebuild Priority: During normal operation, the CPU switches between
tasks to service all active tasks on the system. Creating a RAID array or
rebuilding an existing array can take up a significant amount of the available
percentage of CPU processing power. You can control how the system
prioritizes the rebuild and allocates the system's resources based on your
system's current workload and need for responsiveness. To set the RAID
rebuild priority, choose one of the following from the RAID Rebuild Priority
field:
-
High: The CPU focuses on the RAID rebuilding process. This setting
allows for the fastest possible RAID rebuild at the expense of other
system tasks. File-sharing throughput is adversely affected during a
RAID rebuild when this setting is chosen.
-
Medium: This option gives a balance between the rebuild process and
other system tasks. The rebuild process takes longer than if it was set to
High.
-
Low: The CPU focuses on other tasks versus the RAID rebuild process.
This results in a longer rebuild time on a busy system. However, if the
workload on the system is low, the CPU services the rebuild process
well. Note that if you are repairing an array, this option leaves the array
the most vulnerable of all the options as it takes the longest for the
rebuild to complete.
