Infortrend Smart Technologies
Derived from more than ten years experience in RAID storage design, Infortrend's innovative firmware delivers Smart technologies that provide enhanced storage solutions for every customer environment, from small organizations to large enterprises. These technologies enhance I/O processing, drive handling, and system management.

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. Fibre loops' load balancing is provided within the subsystem. The firmware's embedded intelligent algorithms, such as Adaptive Write Policy and Guaranteed Latency I/O, improve sequential write performance 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 introduced Auto Data Protection Mechanisms. These special SysSmart firmware functions ensure data safety by automatically switching to write-through data caching when abnormal subsystem conditions are detected such as a PSU/cooling module failure, low BBU or UPS battery charge, etc.

By using the firmware to monitor and control 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.
The Eonstor can be monitored by variety of utilities and approaches. I2C internal serial bus, SAF-TE, and SES are seamlessly integrated into the comprehensive Java-based GUI RAIDWatch Manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface.
