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.
