HRW TEMPEST Compute Node
Sub U Systems (SUB-U) Half Rack Width (HRW) TEMPEST Compute Nodes bring a robust enterprise-class cloud computing to the tactical edge of network applications in a TEMPEST compliant appliance. Based on the Intel Xeon D 2173IT processor, the HRW Tempest provides robust computing and real-time data processing at the tactical edge, resulting in reduced command and control (C2) latency and improved situational awareness while keeping the TEMPEST secured.
RuCAS
The Sub U Systems Rugged CSfC Airborne Solution (RuCAS) is a purpose-built appliance designed from the ground up for rotary and fixed-wing aircraft applications, as well as ground and maritime, manned and unmanned, harsh environment applications. The RuCAS is designed for DO-160 flight-qualified and meets MIL-STD-810, and MIL-STD-461.
The RuCAS contains seven (7) Intel® Xeon D or C3000 processors that can be configured with one or more software-based virtualized network function (VNF) or application server virtual machine appliances.
The RuCAS appliance is available with traditional MIL-STD 38999 connectors for airborne and extremely rugged applications, or standard 10G Base-T RJ45 interfaces for interoperability with other COTS equipment.
