Auto
Switch Cache Policy and Auto Shutdown |
| |
When a RAID controller detects conditions
exceeding preset thresholds, the following actions
are initiated 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 reverts from write-through to
write-back mode. |
| |
Intelligent
Drive Handling |
| |
If two bad blocks occur on two member drives of an
array, the integrity of the stored data is
endangered. Media Scan, Infortrend’s innovative
intelligent drive handling function, retrieves data
from the damaged sectors. Media Scan handles low
quality drives in both the degraded mode and during
the rebuild process. For additional data security,
other intelligent drive management features include
the transparent resetting of non-responsive hard
drives, power-failure management, and bad-drive
handling during LD expansion. |
