SYS-621BT-DNC8R
High-Performance 2U BigTwin Multi-Node Rack Server barebone featuring dual-socket Xeon compute density with the SYS-621BT-DNC8R
The SYS-621BT-DNC8R is a 2U Supermicro BigTwin barebone engineered as a 2-node platform, allowing each node to run dual Intel Xeon Scalable 5th/4th Gen (LGA4677/C741) for dense, scalable CPU resources. This architecture targets private cloud, virtualisation, and cluster compute by consolidating independent fault domains while maintaining high per-node core counts and sustained power headroom.
Per node, the SYS-621BT-DNC8R implements a 16-slot DDR5 ECC RDIMM memory topology to support high-capacity, high-bandwidth working sets that are critical for database, analytics, and virtualised consolidation. PCIe 5.0 expansion and OCP NIC 3.0 (PCIe 5.0 x16) enable modern east-west networking and accelerator-class I/O where required, while maintaining low-profile slot accessibility for serviceability. For storage-heavy roles, the SYS-621BT-DNC8R provides 6x 3.5-inch hot-swap bays per node with NVMe/SAS/SATA flexibility, complemented by Broadcom 12Gb/s SAS in IT mode for predictable software-defined storage behavior and dual M.2 NVMe boot options to keep data bays dedicated to capacity and throughput.
Why Choose the SYS-621BT-DNC8R?
The SYS-621BT-DNC8R delivers an efficient density-to-performance ratio by pairing 2 independent nodes with enterprise-grade power, cooling, and management in a single 2U footprint. It is designed for scale-out growth: add nodes with consistent networking, storage, and memory characteristics, while IPMI/BMC, TPM 2.0, and platform firmware protections support controlled operations in shared data centre environments.
Supermicro builds the platform around serviceable modularity, redundant power design, and data centre-aligned thermals, including high-speed fan wall cooling and optional direct-to-chip liquid cooling support. This approach supports sustained operation under mixed compute and storage loads while aligning with modern secure-boot and silicon-root integrity expectations.
Key Applications:
- Private cloud infrastructure
- Virtualisation clusters
- Scale-out object storage
- Backup & recovery nodes
- Database platforms
- Analytics and ETL
