Workload-optimised server

The Supermicro ARS-210M-NR-OTO-53 is a complete server system built for AI, machine learning and high-performance computing workloads. It ships with an Ampere Altra Max M128-30 processor running at 3.0 GHz across 128 cores and 128GB of DDR4-3200 memory. A 960GB SSD provides the boot and data volume.

Compatibility checks before ordering

Verify that your rack provides a 2U slot and that the power distribution can supply the 250W processor TDP. Confirm the DDR4-3200 memory speed matches any existing modules you plan to add. Ensure the operating system and AI frameworks support the Arm-based Ampere architecture.

Upgrade path and value

This system replaces earlier 2U servers that used lower-core-count CPUs for parallel workloads. The jump is worth it when your models or datasets need the 128-core density and the memory bandwidth of DDR4-3200. Buyers who need GPU acceleration or larger local storage should evaluate other configurations.

Questions about this item

Does the ARS-210M-NR-OTO-53 ship with the Ampere Altra Max M128-30 processor and 128GB DDR4-3200 memory already installed?

Yes, the system arrives as a complete server with the 128-core Ampere Altra Max M128-30 running at 3.0 GHz and 128GB of DDR4-3200 memory installed in the chassis.

How do I decide between the 128-core M128-30 model and other Ampere Altra Max SKUs for AI/ML/HPC workloads?

The M128-30 delivers the maximum 128 cores at 3.0 GHz with a 250 W TDP, giving the highest parallel throughput in the Altra Max line for dense AI/ML/HPC tasks.

What does the 3.0 GHz clock speed on the 128-core Ampere Altra Max mean for real-world AI/ML/HPC performance?

All 128 cores sustain 3.0 GHz base frequency, providing deterministic high-frequency compute for parallel AI/ML/HPC workloads without relying on burst behaviour.
