Supermicro SuperServer SYS-422GTS-HLN4R

The Supermicro SuperServer SYS-422GTS-HLN4R is a 4U rack-optimized server built around dual AMD EPYC 9005 Series (Turin) processors, delivering up to 192 Zen 5 cores per system and access to AMD's fifth-generation EPYC architecture. The platform natively supports PCIe 5.0 across all expansion slots, doubling bandwidth compared to PCIe 4.0 predecessors, and integrates CXL 2.0 (Compute Express Link) connectivity to enable coherent memory pooling and disaggregation—critical for AI inference pipelines, in-memory analytics, and large-model serving where DRAM capacity and bandwidth are the primary bottlenecks. The server accommodates up to 24 DDR5 DIMM slots supporting RDIMM and 3DS RDIMM configurations at speeds up to 6400 MT/s per channel, delivering extreme aggregate memory bandwidth suited to latency-sensitive inference and scientific simulation tasks.

Designed with flexibility for GPU-accelerated and CPU-bound workloads alike, the SYS-422GTS-HLN4R provides multiple full-height, full-length PCIe 5.0 x16 expansion slots capable of hosting current-generation NVIDIA or AMD accelerators, as well as high-speed NVMe storage devices. Its dense 4U form factor balances compute density with thermal headroom, featuring a hot-swap backplane for NVMe/SAS/SATA drives and redundant 80 PLUS Titanium power supply units to maintain operational efficiency under sustained peak loads. The HLN4R chassis designation reflects integrated high-bandwidth networking capabilities and redundant power architecture, making the platform an enterprise-grade foundation for cloud service providers, HPC centers, and large-scale AI infrastructure deployments.

Supermicro's IPMI 2.0-compliant Baseboard Management Controller (BMC) with Redfish API support enables out-of-band management, remote power control, and sensor telemetry integration with orchestration platforms such as OpenBMC, Ansible, and third-party data center infrastructure management (DCIM) solutions. The SYS-422GTS-HLN4R was launched in Q1 2025 as part of Supermicro's AI-optimized server portfolio targeting enterprises transitioning to next-generation memory-centric and accelerated computing architectures.
