MEN Mikro MH70R - Rugged 19" Modular Embedded Computer

Intel Xeon D-1500 (Broadwell DE) CPU with up to 16 cores

Introduction

The MH70R main server unit acts as the central component of the menRDC railway data centre. Several distributed functions are combined into a centralized platform, which reduces the number 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. 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 a virtualization platform, it supports Intel VT-x and VT-d technology to virtualize several functions, e.g., 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 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 class TX. The system withstands shock and vibration for reliable operation and a longer product lifetime.

Long-Term Availability

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