Storage
Ethernet Switch
Lower cost during purchase,
installation, maintenance
Component obsolescence does
not affect train IT functions
Lower efforts to integrate
application software
Based on open computer standards
» Mobility 4.0 — open to the IoT
» Independence of a single supplier
» Transparency for the end user
» Virtualization to abstract application from hardware
» Consolidation of multiple applications on fewer systems

I/O Extension
One platform for the complete railway IT infrastructure
More applications on less hardware
save cost, avoid incompatibilities
Easy deployment thanks to standar-
dized office IT like systems
» Main server and virtualization platform
with Intel Xeon D-1500 CPU
» Storage extension with up to 5 HDD/SSD carriers
» Network extension with 29 Gbit/s throughput

5. menRDC Light
Box PCs instead of 19 systems
» All-in-one device
» Server, storage and I/O
» For reduced performance needs
» Space, weight and cost saving
» Built-to-order as 19 CompactPCI
» Device extensions via Ethernet
» Box PC network box
» Box PC 19 system
Cost-effective smaller platforms for
lower application requirements

6. menRDC Software Architecture
Virtualization – abstraction of hardware from
the application
Supported by Linux KVM hypervisor
» Including e.g. VM Manager, Virtual Ethernet Switch
» Supporting para-virtualization, abstraction of guest
from host OS
» Adaptable to support e.g. task monitoring,
high availability
Supported by MH70R
» Multi-core server architecture
» Intel VT-x, Intel VT-d, Intel HT

More applications on less hardware
reduce space, weight, cost
Independence of application reduces
integration time and cost to software

Main Server
Intel server performance in an
EN 50155 compliant environment
Application-ready for all
non-vital train functions
Any mixture of operator and
passenger service applications
Just one server platform - no single
computing equipment anymore

8. menRDC Benefits
Save hardware devices
and avoid system in-
compatibilities
Use standard technologies
and stay independent of a
single vendor
Reduce space, weight, cost,
maintenance
Rely on fully proven rolling
stock and wayside equipment
Get a standard solution
within short time and
tailored to the application
EOL management,develop-
ment, test, consultancy,
application know-how
Save hardware maintenance
cost for 30 years
Reduce integration time
cost – more functions at
software cost only
