EonStor 4U 24 Bay Sata-SCSI Raid

EonStar 24 Bay SCSI-320 to SATA-II (3Gbps) RAID Subsystem

RAID

Multiple arrays configurable with dedicated or global hot spare drives
RAID levels: RAID0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, and NRAID
Online expansion by:
Adding new drives
Copying and replacing drives with drives of larger capacity
Automatic background rebuild
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
