ASUS RS521A-E12-RS24U-2KWT: High-Density 2U 1P Storage & HPC Server

Maximize your data center's Total Cost of Ownership (TCO) with the ASUS RS521A-E12-RS24U-2KWT. This innovative 2U single-socket (1P) rack server is powered by the cutting-edge AMD EPYC™ 9005 series processor, delivering dual-socket-like performance with massive core counts.

Uncompromising Single-Socket Performance

The ASUS RS521A-E12-RS24U redefines what a single-processor (1P) server can achieve. Powered by a single AMD EPYC™ 9005 series processor, it harnesses the immense processing power and high core counts of the Zen 5 architecture. This design allows enterprises to achieve performance levels traditionally reserved for dual-socket systems, significantly reducing per-socket software licensing costs and power consumption while dominating high-performance computing (HPC) and virtualization workloads.

Massive Memory Capacity for a 1P System

Break through single-socket memory limitations. Unlike traditional 1P servers, the RS521A-E12-RS24U boasts a staggering 24 DDR5 DIMM slots (running at 2 DIMMs per channel). This allows data centers to maximize their memory footprint and bandwidth, ensuring data-heavy applications, in-memory databases, and dense virtual machine deployments have the resources they need without stepping up to a costlier 2P platform.

Hybrid Storage Density: 24 NVMe & SAS/SATA Bays

Versatility meets extreme density. The front panel is loaded with 24x 2.5" hot-swap drive bays configured in a highly optimized hybrid layout. It supports 16x blazing-fast NVMe drives for ultra-low latency, high-IOPS storage tiers, and 8x SAS/SATA drives (via an optional RAID/PIKE card) for high-capacity, cost-effective bulk storage. This makes the server an absolute powerhouse for tiered Software-Defined Storage (SDS) environments.

Gen5 Expandability & Enterprise Networking

Future-proof your infrastructure with next-generation bandwidth. The server features 5x PCIe 5.0 expansion slots, allowing for the integration of high-speed storage controllers, DPUs, or computational accelerators. Additionally, it includes an OCP 3.0 Gen5 x16 slot for flexible, ultra-fast networking upgrades, alongside dual onboard Intel I350-AM2 Gigabit Ethernet ports for reliable base connectivity.

Ideal Target Applications:

• Software-Defined Storage (SDS): Perfect for tiered storage architectures leveraging the 16x NVMe + 8x SAS/SATA configuration.
• Virtualization & Cloud Computing: High core counts and 24 DIMM slots allow for incredibly dense, cost-effective VM deployment.
• High-Performance Computing (HPC): Tackle scientific modeling and data analytics with Gen5 throughput and AMD EPYC 9005 compute power.
• Content Delivery Networks (CDN): Fast data caching and streaming utilizing the massive NVMe storage array.
