Frequently Asked Questions
What is a 1U dual node server chassis?
A 1U dual node server is a compact rack-mount chassis that houses two independent server nodes in a single 1U (1.75-inch) rack unit. The ASRock Rack 1U2N2G-B550 allows you to deploy two separate systems with dedicated processors and memory, maximizing compute density while minimizing physical space and power draw per node.
Does the 1U2N2G-B550 support DDR4 ECC memory?
Yes, the ASRock Rack 1U2N2G-B550 supports both DDR4 ECC and non-ECC UDIMM memory. With 4 DIMM slots per node, you can configure up to 8 memory modules total across both nodes, providing flexibility for enterprise deployments requiring error correction or cost-optimized builds.
What processors are compatible with this Socket AM4 platform?
The 1U2N2G-B550 supports AMD Ryzen 5000 Series desktop processors on the Socket AM4 (PGA1311) platform. This enables deployment of high-performance multi-core CPUs ideal for virtualization, containerization, and parallel workloads in a space-efficient 1U form factor.
Why is 1+1 redundant power supply important?
The 1+1 redundant 1200W CRPS configuration ensures continuous operation even if one power supply fails. Both units operate simultaneously at reduced load, and if one fails, the remaining supply maintains full system power. This Platinum-rated design maximizes efficiency while providing enterprise-grade reliability for mission-critical deployments.
