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. |
