IOSmart
IOSmart allows for the flexible configuration of logical
drives, logical volumes and logical partitions and ensures
instant RAID availability via background logical drive
initialization. The firmware’s embedded intelligent
algorithms, such as Adaptive Write Policy and Guaranteed
Latency I/O, improve the performance of sequential write
applications and ensure the fast and continuous flow of
data.
DrvSmart
The DrvSmart utility provides an easy way to store data
while keeping it safe. One of the main DrvSmart functions,
Media Scan, retrieves data from degraded or damaged hard
drives and handles low quality drives in both the degraded
mode and during the rebuild process. Other DrvSmart features
include disk cloning, drive roaming, SMART, transparent
resetting of non-responsive hard drives, and RAID parity
update tracking and recovery.
SysSmart
In addition to RAID protection for the disk drives, Infortrend
has developed a special firmware feature that automatically
changes the data cache policy to write-through mode when
abnormal conditions are detected such as a PSU/cooling
module failure, low BBU or UPS battery charge, etc. By
using the firmware to control the rotation speed of the
enclosure’s dual-speed fans, the fan rotation speed
is raised to a higher level when critical conditions are
detected, e.g., a PSU or fan failure. Fan speed returns
to the lower setting when normal operating status is restored.
Control over caching behaviors, as well as voltage and
temperature self-diagnostics, is also related to enclosure
conditions.

| Auto
switch cache policy and Auto shutdown |
When a RAID
controller detects conditions that exceed the 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 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, 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 hung hard drives, power-failure management, and bad-drive
handling during LD expansion.
