DELL PowerEdge XR4520c 2U rack server DDR4 512GB max

Edge-ready 2U server for VDI and surveillance

The Dell PowerEdge XR4520c is a compact 2U rack server built for edge workloads such as VDI, vSAN, machine vision, point-of-sale and video surveillance. It supports a single Intel Xeon Scalable processor with up to 20 cores and DDR4 registered ECC memory up to 512 GB across four slots. Security features include Silicon Root of Trust, Secure Boot, TPM 2.0 and cryptographically signed firmware.

Suits GPU-accelerated edge inference.

This platform fits deployments needing up to two 150 W single-width GPUs or one 250 W double-width GPU for local inference or transcoding. It also accommodates twelve M.2 NVMe drives via add-in card and riser module. Organisations requiring dual-processor scaling, larger DIMM counts or traditional 2.5-inch drive bays should evaluate alternative chassis.

Verify DDR4 ECC modules and GPU power budget

Confirm that registered ECC DDR4 RDIMMs or LRDIMMs are sourced, limited to 2933 MT/s and the 256 GB or 512 GB per-module ceiling. Ensure the chosen GPU fits the single- or double-width form factor and stays within the 150 W or 250 W thermal envelope. Check that the rack provides front-access clearance for the iDRAC Direct, USB 3.0, serial, Mini-DisplayPort and management Ethernet ports.
