Variable Modular Concept
The MH70R is not a single standard product, it is rather a modular concept, which is available within a project context and therefore very flexible for use in various applications.
Main Server Unit and Centralized Platform
The MH70R main server unit acts as the central component of the railway data center. Several distributed functions are combined into a centralized platform, which reduces the amount of devices within the application environment.
Railway Data Center
The railway data center is the mobile office IT computer for virtually all non-vital train applications, e.g., PIS, media streaming, onboard internet or diagnosis server. It is a general purpose, modular platform. The hardware is solely based on standard technologies, supporting a flexible and scalable configuration of the end system with plug-and-play wireless communication channels, storage extensions, connectivity to other train computers, or I/O interfaces to sensors and actuators. Another standard system offered as part of a railway data center is, e.g., the MH70S data storage system.
High-Performance CPU, Virtualization and Security
The system is based on a high-performance Intel Xeon-D processor. Being an open virtualization platform, it supports Intel VT-x and VT-d technology to virtualize several functions, e.g., video surveillance or ticketing. The software can be developed without hardware which reduces the development time. It also supports a Trusted Platform Module (TPM) for security implemented through cryptography, as well as an error-correcting code (ECC) memory, board and system management control, and a watchdog timer to ensure reliability.
Modular Design
Based on a modular 40 HP CompactPCI Serial system, the MH70R can be wall or rack-mounted and offers a multitude of configuration possibilities resulting in a fast time-to-market.
For the concept, a high-performance, high-bandwidth multi-core CPU board offering 10 Gigabit and Gigabit Ethernet interfaces, legacy serial I/O such as RS232, and USB 3.0 interfaces is available. The most common wireless communication functions can be implemented in the MH70R via CompactPCI Serial peripheral boards, as well as hot-pluggable and easy to exchange HDD/SSD shuttles which allow easy maintenance in the field.
The system is cooled by using an additional fan tray at the bottom of the system. Cooling is independent of the mounting position.
Designed for Harsh Environments
The MH70R is designed for operation in a -40 °C to +70 °C temperature range according to EN 50155. The system withstands shock and vibration for reliable operation and a longer product life-time.
