MH70R - Main Server with Intel Xeon D for Railway Data Center

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. It consists of one 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. The most common wireless communication functions and some storage are implemented on CompactPCI Serial peripheral boards in the system.

menRDC Railway Data Center

menRDC 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 of menRDC 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. Other standard systems offered as part of menRDC are the MH70S data storage system and the NH30 Managed Gigabit Ethernet Switch.

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

The system consists of a modular 40 HP CompactPCI Serial system which can be wall or rack-mounted. The hot-pluggable and easy to exchange HDD/SSD shuttles 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.

The PC offers a multitude of configuration possibilities resulting in a fast time-to-market.

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.

Long-Term Availability

With a guaranteed standard life-time of 7 years the MH70R facilitates the client's life-cycle management by making the system available at least for this time period.
