SBI-421E-5T3N
High-Density 2S SuperBlade Compute Node featuring DDR5 and PCIe Gen5 expansion with the SBI-421E-5T3N
The SBI-421E-5T3N is an 8U Supermicro SuperBlade server module engineered for CPU-dense consolidation where shared chassis power, cooling, and networking deliver predictable scale. The dual-socket LGA4677 platform supports Intel Xeon Scalable 5th/4th Gen processors and Intel Xeon CPU Max Series, enabling high core counts and sustained turbo behavior for virtualisation and private cloud clusters.
For memory-bound workloads, SBI-421E-5T3N provides 16 DDR5 RDIMM slots with ECC, supporting up to 4TB and enabling higher bandwidth per socket for EDA, in-memory services, and dense VM footprints. PCIe Gen5 is exposed through a mezzanine expansion path to keep accelerators, fast NICs, or storage controllers aligned with next-generation I/O. Storage is architected for mixed latency tiers: 2.5-inch hot-swap bays combine U.2 NVMe/SATA flexibility with additional SATA capacity, complemented by an internal M.2 2280 NVMe boot option and optional mezzanine M.2 expansion for node-local performance.
Why Choose the SBI-421E-5T3N?
The SBI-421E-5T3N targets maximum compute density per rack unit while keeping serviceability and lifecycle control inside the SuperBlade ecosystem. SBI-421E-5T3N balances dual-socket performance, DDR5 capacity, and PCIe Gen5 readiness to scale horizontally across clustered deployments, with integrated out-of-band management to standardise operations across large node counts.
Supermicro designs this class of blade module around data centre efficiency, deterministic thermals, and enterprise remote management. With IPMI 2.0, KVM-over-IP, Redfish API support, and security features such as TPM 2.0 and signed firmware, SBI-421E-5T3N aligns with modern governance and automation requirements.
Key Applications:
- Server virtualisation and consolidation
- Private cloud compute clusters
- CPU-dense HPC and EDA
- Memory-intensive analytics
- High-density edge-in-chassis deployments
