The ASRock Rack 1U2N2G-B550 is a compact 1U, two-node server barebone built for AMD Ryzen 5000 processors, with one dual-slot PCIe 4.0 x16 expansion slot per node. It suits AI/ML, HPC, and other rack-based workloads that benefit from two GPU-capable nodes in one chassis.
Recommended For
- Small data-center or lab teams that want two separate Ryzen server nodes in one 1U rack chassis for running distinct services or compute jobs.
- Researchers and developers prototyping GPU-accelerated workloads who need one full-height, dual-slot GPU per node rather than several GPUs in each server.
- Rack operators placing servers in space-constrained environments who value remote IPMI management and redundant power supplies for ongoing operation and maintenance.
