Description

The Dell PowerEdge XR8620t is a single-socket, half-width 2U server sled designed to maximize compute and GPU acceleration within the PowerEdge XR8000r modular chassis. It is the higher-performance, denser option in the XR8000 sled family, allowing for up to two XR8620t sleds per 2U chassis.

This sled is purpose-built for the far edge, where rugged durability and powerful acceleration are non-negotiable. It supports up to three PCIe Gen5 slots, enabling the integration of NVIDIA L4 GPUs or other accelerators essential for heavy workloads like AI/ML training, video processing, and Centralized RAN (Radio Access Network) deployments.

Its modular architecture and front I/O access make it highly adaptable and simplify maintenance in challenging, remote locations like cell towers, factory floors, and field stations. Running on a single Intel Xeon Scalable Processor with DDR5 memory, the XR8620t provides a TCO-optimized, flexible, and powerful platform for extending core data center capabilities to the extreme edge.
