Supermicro SuperServer SYS-220BT-DNTR

The Supermicro SYS-220BT-DNTR is a high-density 2U 2-Node BigTwin™ System designed for enterprise data centers, cloud computing, hyper-converged infrastructure (HCI), and high-performance computing (HPC) environments. Each node operates independently in a multi-node chassis to maximize compute density and power efficiency.

Key Features & Highlights

• High Density: 2 independent hot-pluggable server nodes in a 2U chassis.

• Dual-Processor Compute: Powered by 3rd Gen Intel® Xeon® Scalable Processors per node.

• PCIe 4.0 Support: High-bandwidth I/O performance across NVMe drives and expansion slots.

• Flexible Networking: AIOM (Advanced I/O Module) support, compliant with OCP 3.0 standards.

• High Efficiency: Redundant Titanium Level (96% efficiency) power supplies.
