Supermicro ARS-520M-NPL-OTO-42 rack server, Ampere Altra Q64-22 64-core 2.2GHz, 128GB DDR4, 960GB SSD

Built for scale-out workloads

The Supermicro ARS-520M-NPL-OTO-42 is a 2U rack server built around a single Ampere Altra Q64-22 processor with 64 cores at 2.2GHz. It ships with 128GB of DDR4-3200 memory and a 960GB SSD. A 12Gb/s SAS RAID adapter is included for internal storage expansion. This configuration targets cloud-native deployments, web serving and container platforms that benefit from high core counts in a compact form factor.

Efficient thermal profile

The CPU carries a 95W TDP, allowing the system to run cool under sustained multi-threaded loads. Fan curves are tuned for steady airflow rather than burst speeds, keeping acoustic output low in dense rack rows. Power draw scales predictably with thread utilisation, making capacity planning straightforward for operators managing large fleets.

Replaces older dense compute nodes

This server consolidates workloads that previously required multiple lower-core boxes, reducing rack space and cabling. The jump is worth it when licensing, management overhead or physical density favour fewer, wider nodes. Buyers who need GPU acceleration or specialised vector instructions should evaluate alternative architectures.
