System overview

The Dell™ PowerEdge™ XR11 and XR12 are Dell's latest rugged servers, designed to run complex workloads using highly scalable memory, I/O, and network options in locations constrained by space or environmental challenges.
The PowerEdge XR11 is a 1-socket, short-depth 1U rugged server.
The PowerEdge XR12 is a 1-socket, short-depth 2U rugged server.
The systems feature the 3rd Generation Intel Xeon Scalable Processor with up to 8 DIMMs, PCI Express® (PCIe) 4.0 enabled expansion slots, and a choice of network interface technologies to cover NIC. The PowerEdge XR11 and XR12 systems are unique platforms designed to optimize computing at the edge with performance in mind. The systems are well suited to operate at high temperatures in harsh or space-constrained environments, and are capable of handling demanding processing workloads and applications such as for the Telecom, Military and Defense industries, as well as, for the commercial sector.
Topics:
• Key workloads
• New technologies

Key workloads

There are a diverse set of applications that operate at the Edge and each of these applications has a different set of requirements.
● Retail Applications - Built with a minimum footprint and enterprise compute to optimize expensive retail space and deliver a targeted virtual experience, including video surveillance analytics, point of sale analytics and IoT device aggregation and analytics
● Telco / 5G - Compact and rugged design capable of supporting accelerators for remote private networks requiring AI/ML/DL type workloads. Use cases include MEC, CDN and VRAN
● Military - Reliable DC power in a hardened chassis to support mobile data centers deployed globally to collect and analyze reconnaissance data
