    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
    SysSmart combines enclosure monitoring and firmware management capabilities in order to minimize the chance of down time caused by hardware failures. The Auto data protection mechanisms are developed to ensure data safety. Other SysSmart functions include the event-triggered and the various monitoring utilities and monitoring approaches combined with the powerful RAIDWatch manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface.
    Intelligent Drive Handling
  • In degraded mode: Skipping irreparable blocks to continue rebuild
  • In normal operation: Data block verification and repair

    Maintenance & Availability

    Firmware rolling upgrade on redundant RAID controllers
    Synchronized cache over dedicated Fibre channel
    Comes standard with a Li-ion battery module
    Immediate array availability
    Drive roaming, array configuration on drives
    Controller voltage and temperature self-diagnostics

    Auto switch cache policy and Auto shutdown
    When a RAID controller detects conditions exceeding preset thresholds, the following actions will be exerted to protect the hardware:

  • Automatically flush cached data and switch the array's caching mode from write-back to write-through
  • Commence an auto shutdown

    • What is remarkable is all environmental thresholds associated with this mechanism are user-configurable and that caching mode changes back to write-back once normal condition is restored.
