Grace Superchip 2U Server
The Supermicro ARS-221GL-NR-OTO-33 is a 2U rackmount server built around the NVIDIA Grace Superchip with dual 72-core CPUs and 480GB of LPDDR5X memory. It targets AI, machine learning and HPC workloads that demand high memory bandwidth and GPU acceleration in a compact form factor.
Dual L40S GPUs and Mixed Storage
Two NVIDIA L40S GPUs each provide 48GB of GDDR6 memory for training and inference tasks. Storage combines a 3.84TB E1.S EDSFF SSD with a 960GB M.2 SSD, while eight front hot-swap E1.S bays allow additional NVMe capacity to be added without downtime.
Air-Cooled 500W TDP Installation
The system uses air cooling rated for up to 500W TDP CPUs, so adequate rack airflow is essential. Installers must verify that the 25GbE SFP28 networking matches existing switch ports and that the operating temperature range of 10°C to 35°C can be maintained in the target environment.

Questions sur cet article
Will the LPDDR5X memory need to be replaced or upgraded during the server's lifespan?
The 480GB LPDDR5X memory is soldered directly to the Grace Superchip package and cannot be removed, upgraded or replaced separately.
Which limit appears first when the dual 72-core Grace Superchip and two L40S GPUs run sustained AI workloads?
The air-cooled thermal design is rated for up to 500W TDP CPUs; sustained full-load operation will hit the cooling capacity before other subsystems become the bottleneck.
How much heat and noise should I expect from this 2U system running all day in a 35°C rack?
With dual L40S GPUs and a 500W TDP CPU limit, the system moves a large volume of air through the 2U chassis; expect significant fan noise and exhaust heat that requires adequate rack airflow.
