SYS-F521E3-RTB
High-Density 4U Multi-Node Cluster Server featuring Xeon Scalable and DDR5 architecture with the SYS-F521E3-RTB
The SYS-F521E3-RTB is a 4U FatTwin multi-node platform that consolidates 4 independent single-socket compute nodes into a shared power and cooling domain for efficient scale-out deployments. Each node is built on the Intel Xeon Scalable 5th/4th Gen LGA4677 platform, enabling high core density per rack unit while keeping the thermal envelope predictable for cluster scheduling and virtualisation consolidation.
To sustain bandwidth-hungry workloads, SYS-F521E3-RTB implements 16 DDR5 ECC RDIMM slots per node across 8 memory channels, supporting up to 4TB capacity and up to 5600 MT/s (2DPC) for balanced capacity-to-throughput scaling. PCIe 5.0 expansion per node includes a x16 low-profile slot and an OCP NIC 3.0 SFF slot, aligning the platform with modern high-speed fabrics and storage controllers. Storage is optimised for data/compute convergence with 8 hot-swap 3.5-inch bays per node supporting NVMe/SAS/SATA (controller and cabling dependent), complemented by dual M.2 boot devices for resilient OS placement and fast node provisioning.
Why Choose the SYS-F521E3-RTB?
The SYS-F521E3-RTB is engineered for enterprises that need dense node count with predictable serviceability, delivering a strong density-to-performance ratio through shared 4U infrastructure while maintaining independent node isolation for scale-out growth. With redundant 80 PLUS Titanium power and per-node remote management, the SYS-F521E3-RTB supports consistent operations in HPC, hyperconverged designs, and virtualisation clusters where lifecycle control and repeatable deployment patterns matter.
Supermicro applies a platform-focused engineering approach that prioritises validated thermals, maintainable hot-swap design, and standards-aligned management. In SYS-F521E3-RTB, features such as TPM 2.0, Silicon Root of Trust, and firmware protections support secure provisioning practices expected in modern data centres.
Key Applications:
- HPC and scale-out cluster nodes
- Hyperconverged infrastructure
- Big-data storage and compute convergence
- Enterprise virtualisation clusters
- Secure multi-tenant private cloud
At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your SYS-F521E3-RTB rollout and an extended warranty option up to 6 years to align the platform with enterprise refresh cycles and operational risk requirements.
