FlashDisk COTS?Rugged disk arrays are designed to protect data from certain environmental perils – at COTS prices. Far less expensive than fully rugged systems, the FlashDisk RF-2500 Series is a “hybrid” system that supports both Fibre Channel and iSCSI hosts in the same system. It supports (24) 2.5” disks in the RAID unit and (24) 2.5” or (12) 3.5” disks in expansion shelves. Both HDD and SSD disks are supported. The RF-2500 RAID unit provides up to 48 TB of storage, expandable to 432 TB with 4 TB drives. As COTS rugged, it is protected against dust, moisture, shock and vibration not offered on standard commercial units. The US Army approved these units for field use and has deployed them worldwide in HUMVEE communication trailers in harsh environments. The front door is crafted of sturdy milled aluminum that provides rigidity and structural integrity. It also houses a heavy-duty dust filter to constrict particle flow and provide a moisture shield to protect internal components. The LCD front panel is easily viewed by field personnel, is EMI protected and uses long life pushbuttons. The door 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 heavy-duty base plate for ground, sea and air operations.
FlashDisk Global Manager™ provides all storage services and a centralized management pane for multiple systems. FlashDisk RF-2500 supports a base unit with single or dual redundant controllers with mirrored cache and up to 6 expansion shelves. It delivers over 1 million IOPS. RAID 6 provides dual parity for large arrays to protect against two drive failures and to ensure successful disk rebuilds.
