The Internal RAID Subsystem features a LVD SCSI host attachment and IDE device attachment. Each system model allow one HDD failures without impact on the existing data and failed drive rebuild is transparent to the host.
Environmental information is is accessible to either via the control panel or through serial port. The RAID controller is most cost-effective IDE disk drive array subsystem with completely integrated high performance and data protection capabilities, which are easily integrated into servers and workstations. It can also meet the rapidly growing demand from the Small to Medium Enterprise and SOHO market.
