    FlashDisk RF-3U16 is a rugged version of the commercial FX-3U16 with the same performance levels and Fibre Channel, iSCSI and SAS host support.  However, these “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 – at far less expense than fully rugged systems.  It supports 16 SAS disks (HDDs, SEDs or SSDs) per shelf and provides up to 96 TB of storage in the base unit, expandable to 1,440 TB. The US Army approved these units for field use and has deployed them 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.

    Rugged Design Features

    MIL-STD 810E/833E; NEBS Level 3: Environmental, shock and vibration.

    200G Shock: Tested for the US Navy to withstand 200G shock with 1U mounting tray.

    Milled Aluminum Door: 3/4″ milled aluminum provides rigidity and structural integrity; dust and raindrop seal.

    Reusable Air Filter: Dust and moisture protection, field proven in harsh environments, washable.

    Rugged LCD: Shatterproof LCD protects display under harsh usage and is EMI shielded.

    Gloved Access: Heavy duty “positive feel” LCD pushbuttons and door thumbscrews for gloved use.

    Front Access Power Switch: Perfect when no rear access.

    SEDs & Secure Erase:  Self Encrypted Drives (AES-256) with FIPS 140-2 validation, Seagate Instant Secure Erase.
