Item# KT-AR212E

The AccuRAID AR212E Series is a 2U 12 bay rack-mountable RAID solution designed for file servers, backup, audio/video streaming, and digital video recording. It is capable of up to 384TB of capacity with additional AS212X6S JBOD storage expansion units, and is the perfect solution for applications requiring large storage spaces. Build upon hardware RAID engines utilizes in the AccuRAID rackmount unit, the AR212E provides PCI Express 2.0 x8 of 8000MB/s with cutting edge SAS and SATA hard drive technology. The array supports RAID 0, 1, 0+1, 3,  5, 6, 30, 50, 60 and JBOD modes. Featuring durable, heavy duty steel housing and a user-friendly LCD panel, the AR212E is built with Web or RS232 management Interfaces along with SMTP manager monitoring all system events. The AR212E is an easy to use building block for large storage systems, and is guaranteed to achieve the most cost-effective performance and data protection. The AR212E comes with modular RAID controller, redundant power supply and redundant cooling fans, as well as PCIe 2.0 x8 re-driver card and PCIe x8 cable.

Note: Sans Digital recommends the use of enterprise hard drives when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance.
