      Module failure alert through I2C bus
      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.

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.

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
