Storage Options
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. You can 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 options 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
: Provides 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. 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.
•
Degraded Mode Grace Period
: Set the period of time after which the
system automatically shuts down degraded arrays. You can manually
restart a RAID array that has been automatically stopped by the degraded
