The Internal RAID Subsystem features a choice of Parallel ATA/Serial ATA (PATA/SATA) and IDE device attachment. Each system model allows 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.
