Industrial servers or ruggedised servers: how do you choose the right solution for your critical environments?

An industrial server is designed to ensure reliable operation in demanding professional environments: automation, test benches, monitoring, data acquisition, telecommunications, machine vision, cybersecurity or control systems. It must offer high availability, customisable configuration, simple integration into a 19-inch rack and a lifespan compatible with the long cycles of industrial projects.

A rugged server, on the other hand, goes further in terms of resistance to field conditions. It is intended for severe or hostile environments where conventional servers are unsuitable: shocks, vibrations, dust, humidity, extreme temperatures, EMC/EMI constraints, specific power supplies or reinforced connectors. ECRIN Systems’ OPALE R range is designed to meet these requirements for ruggedised servers in critical applications, notably featuring the OPALE-Rugged and the myOPALE-RS.

In both cases, the right choice depends on striking a balance between performance, form factor, robustness, connectivity, storage, level of customisation and deployment constraints.

The first factor to consider is the application workload. A server designed for monitoring or control will not have the same requirements as a platform for high-performance computing, computer vision, AI, centralised data acquisition or real-time processing.

For an industrial server, you need to look at the type of processor, memory capacity, number of expansion slots, storage options and software compatibility.

The OPALE V2, for example, is based on the PICMG 1.3 form factor, supports 12th, 13th and 14th generation Intel® Core™ processors depending on the configuration, up to 64 GB of DDR5 memory, and offers high expansion capacity of up to 14 full-length cards.

For a high-performance rugged server, the considerations become more critical: server CPU capacity, ECC memory, PCIe expansion, high-speed storage, thermal management, power supply and environmental resilience.

The myOPALE-RS, for example, is designed for Edge AI, HPC and intensive data processing applications, featuring a 6th generation dual Intel® Xeon® Scalable CPU platform, support for dual high-performance GPUs, up to 4 TB of DDR5 ECC memory and NVMe storage.

The mechanical form factor is a key consideration. A 1U rack-mount server helps to reduce space requirements, a 2U chassis often offers a good balance between compactness and expandability, whilst a 4U form factor may be appropriate when numerous expansion cards or specific interfaces need to be integrated.

The OPALE V2 range covers a variety of needs: the 4U OPALE V2 for projects requiring high expandability, the 2U OPALE V2 Compact to optimise the SWaP-C envelope, and the 1U µOPALE V2 for space-saving integrations.

For more demanding environments, the OPALE-Rugged is available in a ruggedised 2U chassis with a depth of 480 mm, a 3U rack option to add a full-height PCIe slot and additional storage, as well as an IP67-rated enclosure resistant to dust and water jets.

In a typical industrial environment, a server must already be reliable, maintainable and durable. But in defence, aerospace, naval, transport, energy or field applications, the requirements are even more demanding.

A rugged server must be designed to withstand physical and environmental stresses: shocks, vibrations, humidity, temperature, dust, EMC/EMI, on-board power supplies or reinforced connectors. The OPALE-Rugged is presented as a high-performance rugged server developed to military standards, with compliance to MIL-STD-810G, MIL-STD-461G, DO-160G and MIL-STD-1275E.

The myOPALE-RS is also designed for critical deployments, with compliance with MIL-STD-810 environmental conditions and a ruggedised design tailored for demanding environments.

Storage must be sized according to the nature of the data: industrial logs, sensor streams, video, radar data, imagery, AI datasets, test files, monitoring or local archiving.

The key criteria to consider are:

• The total capacity required;
• The type of storage medium: HDD, SSD, NVMe;
• Front or rear access;
• Hot-swap capability;
• The need for RAID or redundancy;
• Resistance to shock and vibration;
• The throughput required for real-time applications or high-density data streams.

The OPALE-Rugged notably features removable 2.5-inch SATA-III and SAS-III bays in a 2U configuration, with a 3U option allowing for the addition of SATA/NVMe storage. The myOPALE-RS focuses on NVMe storage with M.2 2280 bays accessible from the rear and additional internal storage.

An industrial or ruggedised server must integrate into an existing system. Connectivity is therefore just as important a factor as computing power.

The following must be checked:

• Available network ports: GbE, 2.5GbE, 10GbE;
• USB, serial, video, GPIO or specific interfaces;
• Available PCIe slots;
• The ability to integrate application-specific cards;
• The type of connectors: standard or MIL-grade;
• Customisation of front or rear I/O.

The OPALE V2 offers high expandability thanks to its backplane, with up to 14 slots for full-length cards. The OPALE-Rugged features configurable MIL-DTL-38999 connectors, including for miniDP, 10GbE, USB-C or MPO fibre optics.

In a mission-critical environment, a server must not only be powerful: it must be monitorable, maintainable and capable of reporting system information. Monitoring functions enable errors to be anticipated, unplanned downtime to be minimised and maintenance to be simplified.

The OPALE V2 range of industrial servers features local and remote management, with Intel® AMT, fan monitoring, system and network information, watchdog, alarms, log files and configuration via text files as per the product pages. Our OPALE R range of ruggedised servers includes IPMI support for monitoring, remote control and system management.

The OPALE V2 is the ideal solution when standard systems are not enough. Based on the PICMG 1.3 form factor, this industrial server is designed for OEMs, system integrators and solution providers who require flexibility, expandability and customisation. It can meet a variety of needs: test benches, intensive FPGA/GPGPU computing, cybersecurity applications, vision, centralised data acquisition or control/command.

Ideal for: industrial projects requiring numerous expansion cards, a customised configuration, long-term availability and a high degree of adaptability.
