SYS-221BT-HNR
High-Density 2U Multi-Node Rack Server featuring NVMe-Dense Scale-Out Architecture with the SYS-221BT-HNR
The SYS-221BT-HNR is a 2U Supermicro BigTwin 4-node platform engineered for scale-out node pools where per-node performance, local NVMe bandwidth, and serviceability must coexist within shared power and cooling boundaries. Each node supports dual-socket Intel Xeon Scalable 4th/5th Gen processors on the C741 platform (LGA4677), enabling strong core density for virtualisation, databases, and distributed analytics, with optional direct-to-chip liquid cooling support for sustained high-TDP operation.
To keep compute fed, SYS-221BT-HNR provides a DDR5 ECC RDIMM memory architecture with 16 DIMM slots per node for large in-memory footprints and predictable error handling. PCIe 5.0 expansion per node is aligned to modern I/O fabrics through a PCIe 5.0 x16 low-profile slot and an OCP NIC 3.0 SFF interface, supporting high-throughput east-west traffic when paired with the appropriate NIC. Storage is optimised for all-flash designs: 6 hot-swap 2.5" NVMe bays plus dual M.2 22110 NVMe (PCIe Gen4) per node, complemented by SATA connectivity for additional device integration, making SYS-221BT-HNR well-suited to NVMe HCI and private cloud clusters requiring deterministic latency.
Why Choose the SYS-221BT-HNR?
SYS-221BT-HNR delivers a practical density-to-performance ratio by consolidating 4 independent dual-socket nodes into a 2U footprint while preserving per-node isolation for lifecycle management and failure-domain control. The SYS-221BT-HNR design supports scalable deployment patterns for homogeneous node pools, combining redundant hot-swap power, shared cooling efficiency, and enterprise-grade remote management to standardise operations across racks.
Supermicro focuses on modular engineering, serviceable chassis design, and alignment with modern data centre standards, enabling consistent platform qualification and long-term reliability in multi-node environments where predictable thermals, power delivery, and IPMI-based management are operational requirements.
Key Applications:
- All-flash NVMe HCI node pools
- Private cloud and virtualisation clusters
- High-density database tiers
- Scale-out HPC and analytics
At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your SYS-221BT-HNR configuration and rollout plan, helping you standardise node pools with procurement clarity. For long-term operational assurance, you can extend the warranty up to 6 years to match enterprise lifecycle requirements.
