| Auto
switch cache policy and Auto shutdown |
When a RAID controller detects conditions exceeding preset thresholds,
the following actions will be exerted to protect the hardware:
Cached data is automatically flushed and
the array’s caching mode switches from write-back to
write-through mode.
If conditions persist past the preset period
of time, auto shutdown of the controller will commence.
All thresholds associated with this mechanism are user configurable
and, once a subsystem manager restores the normal operating
conditions, the caching mode changes from write-through back
to write-back mode.
