The b-plus DATALynx ATX4 is a 19-inch server designed for test vehicles, where teams need to develop and validate algorithms using vehicle data. Its documented configuration options combine AMD EPYC 7002 or second-generation Intel Xeon Scalable processors with liquid cooling, PCIe expansion and room for SATA SSDs. It is intended for engineering workloads such as AI, image processing and neural networks—not as a consumer desktop. b-plus announced the platform in February 2020; its published specifications should not be assumed to describe every configuration currently available.
What is the DATALynx ATX4 for?
b-plus describes the DATALynx ATX4 as an in-vehicle development and validation server. It brings server-class CPU and GPU capability into a test vehicle so engineering teams can record and process data while developing algorithms, image-processing systems and neural networks. That makes it relevant both to compute-heavy development and to workflows that need vehicle data captured for later analysis.
The product is not a general-purpose desktop or a consumer AI workstation. Its 19-inch server format and automotive power and thermal specifications are intended for vehicle integration. b-plus’s product information is available on its DATALynx ATX4 page.
What compute and expansion options are documented?
Processor platforms
b-plus lists AMD EPYC 7002 and second-generation Intel Xeon Scalable processor families for the platform. The product materials do not provide benchmark results that would establish how quickly a particular configuration trains or runs a model.

PCIe and graphics cards
The ATX4 offers up to seven PCIe 3.0 slots. b-plus also describes support for up to five graphics cards through future add-ons. Those are maximum, configuration-dependent expansion figures—not a guarantee that every unit ships with seven usable slots or five GPUs installed.
On-board storage
The chassis can accommodate up to 10 SATA SSDs. That gives the server a role in vehicle-data recording as well as algorithm development, but the number of drive bays alone does not establish sustained recording throughput or endurance for a particular sensor workload.

Can it operate in vehicle conditions?
b-plus specifies a liquid-cooled ambient operating range of -10°C to 60°C and an automotive supply-voltage range of 6–32 V. These figures describe the published platform envelope; they do not replace vehicle-level checks for installation, airflow, vibration, power transients or the requirements of a specific deployment. Confirm the intended configuration and integration conditions with b-plus.
How does MDLake relate to ATX4?
MDLake is a related b-plus mobile data-storage system, not a capacity figure to apply automatically to every DATALynx ATX4 build. b-plus material describes MDLake with a 2×64 Gb/s write rate and 60 TB capacity. The source does not make clear when that document was published, and the figures should be treated as MDLake system specifications rather than guaranteed ATX4 performance.

For teams evaluating a vehicle workflow, the distinction matters: ATX4 is positioned as the compute and development server, while MDLake addresses mobile data storage. b-plus presents the systems in a broader data-management product range.
What should teams check before choosing it?
- Workload: Establish whether the priority is algorithm development, neural-network inference, image processing, or recording and replaying raw sensor data.
- Vehicle integration: Validate the voltage input, temperature envelope and physical installation against the test vehicle and operating environment.
- Accelerator configuration: Confirm which PCIe slots, GPUs and add-ons are supported in the exact configuration under consideration.
- Storage workload: Match SSD count and sustained write requirements to sensor volume, retention needs and recording duration; the published drive count does not by itself prove a particular write rate.
- Workflow fit: Check compatibility with the relevant b-plus Aveto and MDLake tools as well as the team’s simulation, validation and test-data processes.
- Measured performance: Request configuration-specific throughput, latency or training/inference benchmarks. The published sources do not provide comparative performance results.
- Current status: The ATX4 announcement dates to February 2020. Confirm current configurations, availability and pricing directly with b-plus rather than treating historical specifications as a current offer.
Where does it fit in automotive AI work?
The platform’s role aligns with data-driven development in which algorithms are tested against real vehicle data. TH Deggendorf describes high-performance AI-server infrastructure and in-vehicle big-data analytics for data-driven algorithms in its AI-server project information. Separately, ZF identifies b-plus technologies GmbH as a partner in the EEmotion automated-driving AI project; ZF describes the project objective as an AI algorithm-based control system for more precise trajectory control in varied driving situations. That context illustrates the kind of engineering environment in which an in-vehicle compute platform can be relevant, but it is not an independent ATX4 benchmark.
