Maintenance & Availability
Immediate array availability
Drive roaming, array configuration on drives
Controller voltage and temperature self-diagnostics
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:
Automatically flush cached data and switch the array's caching mode from write-back to write-through
Commence an auto shutdown
What is remarkable is all environmental thresholds associated with this mechanism are user-configurable and that caching mode changes back to write-back once normal condition is restored.
