Industry-leading memory capability
With 16 RAM slots that support up to 2TB of fast, DDR4-2666MHz 3DS ECC RDIMMs or LRDIMMs, RS520-E9-RS12-E delivers industry-leading memory capability for your business.

The best storage interface combination for software-defined storage management
12x 3.5" / 2.5’’ hot-swap storage bays (supports 4x 2.5’’ NVMe or SAS or SATA devices).

Optimized storage with hot-swap bays and 2x M.2
RS520-E9-RS12-E features 2 additional 2.5" hot-swap storage bays on its back panel and 2x onboard M.2 slots that can be used for the main system disk as well as for memory caching. The dual M.2 SSDs can be configured as PCI-E RAID with Intel® VROC to speed up storage caching.

Powered by the latest 2nd Gen Intel Xeon Scalable processors
RS520-E9-RS12-E is built on the latest 2nd Gen Intel® Xeon® Scalable processors to deliver incredible performance and features 16 DIMM slots that provide best-in-class memory capacity and bandwidth. It offers breakthrough performance with the latest Intel Optane™ DC persistent memory with an over 88% gain in input/output operations per second (IOPS) compared with the same configuration in SSD. Featuring the latest Intel Deep Learning Boost technology to enhance deep learning capabilities, RS520-E9-RS12-E achieves a 3.1X performance improvement in the ResNet-50 and SSD VGG-16 models, fully demonstrating the inference capability of the new platform. The Intel® Xeon® Scalable platform also delivers better virtualization performance, enabling 4.2X more virtual machines (VMs) per system.

Smart thermal design for energy efficiency
The Server features a smart Thermal Radar and Auto Fan Control design with more ambient thermal sensors for the CPU, memory, GPU and front-panel board that provide improved temperature monitoring and enable dynamic fan speed adjustment for better power efficiency.

Rack-optimized thermal performance
With the CPU and memory configured in a front parallel design that enables efficient airflow for excellent thermal performance, RS520-E9-RS12-E is optimized for rack placement.
