Infortrend RAID Controller Manual

Data Safety:
Redundant Controller
firmware
synchronization
Regenerate Parity of
logical drives
In the event of controller failure, a replacement controller
running a different version of firmware can be combined to
restore a redundant system with a failed controller.
Different firmware versions can be auto-synchronized
later.
Supported. Can be performed every so often by user to
ensure that bad sectors do not cause data loss in the
event of drive failure.
Supported. Automatic reassignment of bad block
Bad block autoreassignment
Battery backup for Supported. The battery backup solutions provide long-
cache memory
lasting battery support to the cache memory when power
failure occurs. The unwritten data in the cache memory
can be committed to drive media when power is restored.
Verification on Normal Supported. Performs read-after-write during normal write
Writes
processes to ensure data is properly written to drives.
Verification on Rebuild Supported. Performs read-after-write during rebuild write
Writes
to ensure data is properly written to drives.
Verification on LD Supported. Performs read-after-write during logical drive
initialization writes initialization to ensure data is properly written to drives.
Drive S.M.A.R.T. Supported. Drive failure is predictable with reference to
support
the variables detected. Reaction schemes are selectable
from Detect only, Perpetual Clone and Copy + Replace.
These options help to improve MTBF.
Clone Failing Drive Users may choose to clone data from a failing drive to a
backup drive manually
System Security:
Password protection Supported. All settings requires the correct password (if
set) to ensure system security.
User-configurable Supported. After certain time in absence of user
Password validation interaction, the password will be requested again. This
timeout
helps to avoid unauthorized operation when user is away.
