Patrol Read Rate Displays the percentage of system resources dedicated for running the
Patrol Read operation. Patrol Read Rate changes the amount of
system resources assigned for the patrol read task. The Patrol Read
Rate can be configured between 0% and 100%, where:
• 0% — indicates the lowest priority for controllers and has the least
impact on the system performance.
• 100% — indicates the highest priority for controllers and has a
greater impact on the system performance.

about patrol read, see Setting The Patrol Read Mode.
Cluster Mode Indicates whether the controller is part of a cluster configuration.
Persistent Hot Spare Displays if the hot spare is persistent. The possible values are:
• Enabled — The slot corresponding to the hot spare drive is
persistent. Any drive in the slot functions as a hot spare if the drive
is qualified to be a hot spare. If the drive contains foreign data, it is
overwritten.
• Disabled — The slot corresponding to the hot spare drive is not
persistent. If the drive is removed from the slot and any drive is
inserted, the slot stops functioning as a hot spare. You need to
manually assign the drive as a hot spare again.
