4-fach SCSI-to-SATA II System mit 1x Ultra320 SCSI Host

The EonStor A04U-G2421 provides unmatched RAID functionality with its wide variety of array configuration, maintenance, and monitoring capabilities. The subsystem delivers a cost-effective RAID storage solution.
This new subsystem takes advantages of SATA-II technology enhancements such as 3Gbps (Gigabit per second) transfer rates, Native Command Queuing for Digital Video content, such as surveillances systems, SOHO environments, and entry-level server attached storage.
