The Supermicro ARS-121L-DNR is a 1U, two-node barebones server with one NVIDIA Grace CPU Superchip per node, designed for data-center teams building dense compute infrastructure; each node offers up to 480GB of onboard LPDDR5X memory and 900GB/s NVLink C2C. Pending a firmware fix, the system currently supports four E1.S drives and two GPUs.
Recommended For
- HPC and engineering teams running Arm-compatible, CPU-bound simulations—such as structural or crash analysis—who can use a dense, dual-node Grace platform; Ansys has published an LS-DYNA benchmark using this server.
- Data-center teams running CPU-based analytics or other memory-intensive workloads that benefit from Grace’s large onboard LPDDR5X capacity and bandwidth, rather than needing an installed GPU in each node.
- Cloud and infrastructure operators consolidating two independent compute nodes into 1U rack space for supported Arm-based services, clustered HPC, or data-center workloads.
- Networking and infrastructure teams building Grace-based nodes around supported BlueField-3 or ConnectX-7 adapters for data-center connectivity or offload tasks.
