Supermicro SYS-121H-TNR – 1U Hybrid Storage Server
The SYS-121H-TNR is a versatile 1U rackmount server designed for flexible storage configurations. Featuring Intel® Xeon® E-2300 series processors (up to 8C/16T), this system combines performance and storage adaptability in a compact form factor. The hybrid drive configuration includes 4 hot-swap 3.5″ bays for high-capacity HDDs and 2 internal 2.5″ bays for SSDs, making it ideal for mixed workload environments. With support for up to 128GB DDR4 ECC memory, PCIe 4.0 expansion, and optional hardware RAID, the 121H-TNR delivers balanced performance for edge computing, content delivery networks, and light virtualization workloads. The system includes dual 1GbE ports and IPMI 2.0 for remote management, powered by efficient 550W (80Plus Platinum) power supplies.
Supermicro SYS-1125HS-TNR – 1U High-Density Storage Server
The SYS-1125HS-TNR is a storage-optimized 1U server featuring an exceptional 12 hot-swap 3.5″ drive bays, offering massive storage capacity in minimal rack space. Powered by Intel® Xeon® E-2300 series processors (up to 8C/16T) and supporting up to 128GB DDR4 ECC memory, this system is specifically engineered for high-capacity storage applications. The 1125HS-TNR excels in NAS/SAN deployments, backup solutions, and media storage with its 12-bay configuration supporting both SAS3 and SATA drives. Enterprise features include PCIe 4.0 expansion, optional hardware RAID controllers, and dual 1GbE ports with IPMI 2.0 management. The high-airflow cooling design ensures reliable operation with dense HDD configurations, supported by 550W redundant (80Plus Platinum) power supplies.
Key Differentiators:
-
The 121H-TNR offers hybrid storage flexibility (4x 3.5″+2x 2.5″) for mixed HDD/SSD workloads
-
The 1125HS-TNR provides maximum storage density (12x 3.5″) for capacity-focused applications
-
Both share the same compute platform but specialize for different storage use cases
-
The 1125HS-TNR features enhanced cooling for full HDD population operation
