Description

The Dell PowerEdge XR12 is a ruggedized, compact 2U rack server engineered for demanding edge environments that require more storage capacity and expansion capability than a standard 1U form factor. While maintaining the XR line's signature short depth of just 400 mm (15.74 inches), the XR12 is built to the highest durability standards, including MIL-STD, NEBS Level 3, and Marine Compliant certifications.

Powered by a single 3rd Generation Intel Xeon Scalable processor, the XR12 delivers robust performance for mission-critical applications in telecommunications, defense, and industrial settings. The 2U design accommodates up to six 2.5-inch drives (SAS/SATA/NVMe) for increased local data storage (up to 92TB) and supports significantly more PCIe expansion (up to 5 Gen4 slots) and higher-power accelerators compared to the XR11.

The server is highly adaptable to existing infrastructure, featuring both Front and Rear I/O port options and configurable airflow (reverse airflow support). Its combination of enterprise performance, expanded capacity, and extreme durability makes it an ideal platform for consolidating and running complex applications at the most challenging edge locations.
