ASUS RS501A-E12-RS4U: Industry-Leading Memory Capacity in a 1U Rack Server

Optimize your enterprise infrastructure with the ASUS RS501A-E12-RS4U, a highly economic and powerful 1U single-socket rack server. Designed for general-purpose and enterprise applications, it is driven by 5th Gen AMD EPYC™ 9005 series processors featuring AMD 3D V-Cache™ technology. 

Uncompromising 1U Single-Socket Compute

The ASUS RS501A-E12-RS4U delivers incredible performance through its optimized single-socket (1P) design. Built on the SP5 platform, it supports both AMD EPYC™ 9005 series and 9004 series processors with a massive TDP of up to 450W. Featuring AMD 3D V-Cache™ technology, this server provides the extreme core counts, cache sizes, and clock speeds required to drive demanding enterprise applications, allowing you to achieve elite performance while reducing per-socket software licensing costs.

Industry-Leading Memory Capability

Break through standard 1P memory limitations. The RS501A-E12-RS4U features an extraordinary 24 DDR5 DIMM slots arranged in a 12-channel, 2 DIMM per channel (2DPC) configuration. This industry-leading memory architecture supports up to 3,072GB of capacity and ultra-fast DDR5 6400/5600 RDIMM speeds (with 9005 series). This makes it an absolute powerhouse for memory-bound workloads, virtualization, and in-memory database processing.

Economic Storage & Gen5 Expandability

Designed for versatile rack placement, the front panel is equipped with four 2.5" hot-swap storage bays supporting a mix of NVMe, SATA, or SAS devices. Internally, it features two M.2 sockets (Gen4 x4 or SATA) up to 22110 form factor for rapid OS booting. For future-proof scalability, the server includes three PCIe Gen5 slots (including FHHL and LPHL options) and one OCP 3.0 socket (Gen5 x16), ensuring you have the high-speed bandwidth necessary for advanced networking or accelerator cards.

Comprehensive IT Infrastructure Management

Ensure maximum uptime and seamless administration with ASUS's comprehensive management solutions. The server comes equipped with reliable dual-port Intel I350-AM2 Gigabit LAN. For remote administration, it features an embedded ASMB11-iKVM (BMC, AST2600) module for complete out-of-band KVM-over-IP control, and is bundled with ASUS Control Center for centralized, in-band IT infrastructure management.

Ideal Target Applications:

• General-Purpose Rack Server: A perfectly balanced, economic compute node for web hosting, file serving, and internal IT services.
• Enterprise Applications: Leverage the massive 3TB memory capacity for complex databases, CRM, and ERP systems.
• Virtualization: High core counts and 24 DDR5 DIMMs allow for dense, cost-effective virtual machine deployment in a compact 1U chassis.
