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.
