Maintenance & Availability |

Optional Li-ion battery support |

Immediate array availability |
| |
Drive roaming, array configuration on drives |
| |
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. |
