SYS-621H-TN12R
High-Performance 2U Rack GPU and Storage Server Architecture with the SYS-621H-TN12R
The SYS-621H-TN12R is a 2U dual-socket LGA4677 platform engineered for Intel Xeon Scalable 5th/4th Gen (Emerald Rapids/Sapphire Rapids) compute, balancing PCIe 5.0 expansion with dense front-access storage for mixed AI and data-centric workloads. With the Intel C741 chipset and support for up to 350W TDP per CPU, the design targets predictable throughput under sustained utilization while maintaining serviceability for enterprise racks.
Memory bandwidth and capacity scale through 32x DDR5 ECC RDIMM slots, enabling high-memory virtualization, in-memory databases, and CPU-assisted inference pipelines, including support for Intel Xeon CPU Max (HBM) where applicable. SYS-621H-TN12R storage is optimized around 12x 3.5in hot-swap bays supporting NVMe U.2, SAS, or SATA, allowing hybrid arrays aligned to software-defined storage or high-IOPS datasets; dual internal M.2 slots provide isolated boot resiliency. For acceleration, SYS-621H-TN12R offers a GPU-capable option with up to 4x PCIe 5.0 x16 double-width slots, and an alternative expansion profile for auxiliary PCIe devices where GPUs are not required. Modular networking is enabled via dual AIOM/OCP NIC 3.0 slots plus dedicated 1GbE BMC/IPMI for out-of-band control.
Why Choose the SYS-621H-TN12R?
The SYS-621H-TN12R delivers an efficient density-to-performance ratio by combining dual-socket compute, PCIe 5.0 lane availability, and a 12-bay hot-swap storage plane in a 2U envelope. This consolidation reduces node sprawl for AI inference, storage-heavy analytics, and virtualized services while preserving scalability through modular NICs, GPU-ready expansion, and redundant 80 PLUS Titanium power for operational continuity.
Supermicro engineering emphasizes modular server building blocks, validated thermal and power design, and standards-aligned management through IPMI/BMC to integrate cleanly into modern data centre automation and lifecycle processes.
Key Applications:
- AI inference and ML training with PCIe GPU acceleration
- Software-defined storage and NVMe/SAS/SATA hybrid arrays
- Virtualization clusters
- Database and application serving
At Happyware - Server Hardware you benefit from Non-Binding Offers tailored to your SYS-621H-TN12R configuration targets and an Extended Warranty up to 6 years to secure long-term platform availability for enterprise deployment cycles.
