    COTS Rugged FlashDisk All Flash Array

    FlashDisk RA-2U24 is a rugged version of an All Flash Array offering high performance levels and Fibre Channel and iSCSI host connectivity support.

    The RA-2U24 has been designed to store data in native format without compression or de-duplication. Why?  We view them as technologies designed to solve legacy problems based on older flash technologies.  With the advent of newer, higher density enterprise class flash drives, we simply don’t need compression or de-duplication to build a cost competitive, high performance array.  With the RA-2U24, your data is never modified from its original format, so there’s no risk of data loss due to de-duplication hashing conflicts, or compression or de-duplication table corruption. Your data is always secure, always protected.

    These RA-2U24  “COTS Rugged” disk arrays are designed to MIL-STD 810E/833E to store and protect data in harsh operating environments: tolerating levels of dust, moisture, shock and vibration not possible with standard commercial units – but far less expensive than fully rugged systems.  It supports 24 2.5” SSDs or SED capable SSDs per shelf and provides up to 92 TB of storage in the base unit, expandable to 276 TB.

    The RA-2U24 is the next generation of the rugged array already approved by the US Army for field use and deployed worldwide in HUMVEE communication trailers. The front door is crafted of 3/4-inch milled aluminum to provide rigidity, structural integrity and prevent flying-object hazards. It also contains a heavy-duty filter to trap dust particles and provide a moisture shield to protect internal components. The LCD front panel is easily viewed by field personnel, is EMI shielded, and uses heavy-duty “positive feel” pushbuttons. The door also features a dust and raindrop seal. Optionally, the US Army, Navy and Air Force mount the unit to a chassis using five bolts, secured in a triangulated pattern for strength, to a Rugged 1U Tray for land, sea and air operations.
