module
- One (1) per power supply
unit
- Three (3) per LCD panel
- Six (6) per RAID
controller module
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.
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, the
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 hung hard drives,
power-failure management, and bad-drive handling
during LD expansion.
