SYS-221BT-HNC8R
High-Density 2U 4-Node BigTwin Cluster Server featuring PCIe Gen5 I/O with the SYS-221BT-HNC8R
The SYS-221BT-HNC8R is a 2U 4-node shared-chassis barebone platform engineered for high-density cluster compute, consolidating 4 independent dual-socket nodes into a single thermal and power domain. Each node supports Intel Xeon Scalable 5th/4th Gen processors on the LGA4677 C741 platform, enabling consistent multi-tenant performance for virtualisation, containers, and CPU-centric HPC where predictable per-node isolation is required.
Per node, the SYS-221BT-HNC8R provides 16 DDR5 ECC RDIMM slots to scale memory bandwidth and capacity for data-intensive workloads, while maintaining enterprise correctness under sustained utilisation. Expansion is optimised around PCIe 5.0 with a dedicated OCP NIC 3.0 SFF interface and a PCIe 5.0 x16 low-profile slot to align I/O with modern fabrics and NVMe-heavy designs. Storage architecture supports up to 6 hot-swap 2.5-inch NVMe/SAS/SATA bays per node for flexible all-flash or mixed-tier configurations, complemented by dual M.2 22110 NVMe PCIe Gen4 devices for resilient boot or local metadata tiers.
Why Choose the SYS-221BT-HNC8R?
The SYS-221BT-HNC8R maximises density-to-performance by delivering 4 serviceable compute domains in 2U without sacrificing per-node memory, PCIe Gen5 connectivity, or hot-swap storage access. Its shared chassis design streamlines cabling, power distribution, and rack footprint, supporting scalable cluster growth with consistent node profiles and simplified spares strategy for enterprise operations.
Supermicro engineering focuses on data centre operability: redundant hot-swap power with high-efficiency conversion, balanced cooling options including optional direct-to-chip liquid cooling, and lifecycle controls through standard IPMI/BMC management. Platform security is reinforced with Silicon Root of Trust and TPM 2.0 to support signed firmware, secure boot, and attestation-aligned deployment practices.
Key Applications:
- High-density virtualisation clusters
- Kubernetes and container nodes
- HPC compute clusters (diskless or NVMe-local)
- HCI and all-flash storage nodes
- Secure enterprise compute pools
At Happyware - Server Hardware you benefit from non-binding offers tailored to SYS-221BT-HNC8R node counts, network profiles, and storage layouts, plus an extended warranty up to 6 years to protect long-lived cluster investments.
