Description

The Dell PowerEdge XR11 is a compact, highly durable 1U rack server engineered to deliver enterprise-grade performance and reliability in the most challenging and non-traditional IT environments. With a short-depth chassis of just 400 mm (15.74 inches), it is ideal for space-constrained locations like telecom central offices, remote military installations, and industrial control rooms.

The XR11 is built to be a workhorse, featuring a single 3rd Generation Intel Xeon Scalable processor with support for up to 36 cores, 1TB of DDR4 memory, and Intel Optane Persistent Memory. Its design is heavily focused on resilience, carrying certifications such as MIL-STD, NEBS Level 3, and Marine Compliant, protecting it from extreme temperatures, shock, vibration, and dust.

Key features include versatile storage (supporting 4x 2.5" NVMe/SAS/SATA drives), three PCIe Gen4 slots for accelerators (up to 2x 70W GPUs), and a robust, integrated Quad-Port 25GbE LOM for high-speed networking. Furthermore, it offers Front and Rear I/O port access options, allowing administrators to customize the airflow direction and servicing model to fit existing infrastructure without costly HVAC overhauls.
