RU5 Portable Rugged RAID

5 TB Compact RAID for Harsh Environments

Now you can take your demanding enterprise data-intensive application on the road! RU5 is a lightweight portable RAID subsystem built to extreme military standards to withstand any harsh field environment. It's easy to deploy: simply plug and play with any host having an Ultra320 SCSI adapter port. Ideal for transportable ground, shipboard or airborne data applications for emergency, military, police, oil exploration, mining, field studios, mapping, video, data acquisition and field data analysis.

Ruggedization
RU5 is designed to meet MIL-STD-810-E for environmental compliance and MIL-STD-461-D for Electromagnetic Interference (EMI). The solid seam welded sturdy aluminum construction throughout is designed to withstand very vigorous handling. The hinged front door is secured with two thumbscrews and provides easy access to the “hot-swap” drive carriers.

Individual drive lockdown thumbscrews secure each drive to the chassis to minimize vibration avoiding potential read/write errors. With this sturdy protection, RU5 has been deployed by the military at hundreds of installations worldwide with field proven reliability and performance.

RAID Data Protection
RU5 is typically configured as a RAID 5 array with single parity, RAID 6 array with dual parity or as RAID 1+0 arrays (striped mirror sets). The high speed hardware ASIC parity engine automatically rebuilds data on a “hotspare” disk or when a drive is replaced.

Ease of Use
The RU5 is “plug and play” with any Ultra320 SCSI host adapter, using any operating system with no host software to load. It incorporates best practices in military design storage, emissions, and environmental. Storage is managed securely from the RU5 Web GUI via the LAN port, the front LCD console or from the RS232 port with error reporting in easy-to-understand terms.
