RAID
- Multiple arrays configurable with dedicated or global hot spares
- RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, NRAID and JBOD
- Online expansion by:
- Adding new drives
- Copying and replacing drives with drives of larger capacity
- Automatic background rebuilds
- Configurable stripe size and write policy per array
- Intelligent drive handling:
- In degraded mode: skips irreparable blocks to continue rebuild
- In normal operation: data-block verification and repair

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. |
