Four-Socket Xeon Server for Mission-Critical

The Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5120 processors. Each CPU runs at 2.2 GHz with 14 cores and can turbo to 3.2 GHz. The system ships with 256 GB of DDR4 2400 MHz registered ECC memory across 48 slots. It targets organisations that need dense compute for databases, virtualisation or real-time analytics in a compact rack footprint.

Storage Controller and Network Flexibility

A PERC H730P controller with 2 GB cache manages the eight 2.5-inch drive bays, supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through. Two 800 GB SATA SSDs are installed. An Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports. iDRAC 9 Enterprise provides dedicated remote management. The chassis includes ready rails and a front bezel for immediate rack integration.

Redundant Platinum Power and Thermal Design

Dual 1600 W platinum-efficiency power supplies deliver hot-swap redundancy for continuous operation. The 3U form factor allows airflow optimised for four-socket density while keeping acoustic levels suitable for standard data-centre aisles. Power draw scales with workload across the 56 total cores and memory subsystem, with the platinum units maintaining high efficiency across the load range.

Questions about this item

How many processor cores are available when all four Xeon Gold 5120 CPUs are fully utilised?

Four 14-core processors give 56 cores in total, each running at 2.2 GHz with a 3.2 GHz turbo frequency.

What is the power supply rating and efficiency for continuous 24/7 operation?

Two redundant 1600 Watt platinum-efficiency hot-swap power supplies share the load and keep the system running if one unit fails.

Which memory specification must match the installed 256 GB DDR4 modules for any future upgrade?

DDR4 2400 MHz registered ECC modules are required; the server has 48 slots and supports up to 6 TB total capacity.
