GbE(x4) / 6Gbps eSATA / USB 3.0 to SATA RAID Storage Subsystem

The ARC-5066 RAID controller is a family of 8/12/16/24 6.0Gbps SATA hard drive ports depending upon the amount of storage required. The ARC-5066 supports multiple host interfaces; eSATA lll, iSCSI or USB 3.0 that can work with different application requirement.

When properly configured, the RAID subsystem can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. The 4 port iSCSI connections deliver high performance, advanced function, high availability, and scalable storage capacity with both direct iSCSI host and IP network connectivity.
