| RAID |
|
Multiple arrays with Dedicated, Global, or
Enclosure-specific hot spares
RAID levels supported: RAID 0, 1 (0+1), 3, 5, 6,
10, 30, 50, 60, and NRAID
ASIC400 backbone
Configurable stripe size and write policy per
array
Automatic background rebuild
Online expansion by:
-- Adding new drives
-- Copying and
replacing drives with drives of larger capacity
Independent array stripe size and write
policy
Intelligent drive handling:
-- In degraded mode: skips irreparable blocks to continue
rebuild
-- In normal operation:
data-block verification and repair
Intelligent reactive and preventive mechanisms:
-- Automated cache flush
--
Automated Media Scan
-- Automated
caching mode

| 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 Adaptive Write
Policy and Guaranteed Latency I/O algorithms improve write
performance and ensure fast and continuous data flow. |
| DrvSmart |
|
The
DrvSmart utilities manage disk drive defects and help
ensure data integrity. 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, 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 SysSmart
functions include the event-triggered cache flush and the
various 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. |
