CPU Model Gold 5120

  • Four 14-core Xeon Gold 5120 CPUs at 2.2 GHz with 3.2 GHz turbo
  • 512 GB DDR4 ECC memory across 16 modules for large workloads
  • PERC H730P controller supports RAID 0 1 5 6 10 50 60
  • Eight 400 GB SATA SSDs provide fast storage in 2.5 inch bays
  • iDRAC 9 Enterprise enables remote management with dual 1600 W platinum power supplies

Mission-critical compute density

The Dell PowerEdge R940 is a 3U rack server built for databases, virtualisation and analytics workloads that demand four-socket scalability in a compact form factor. It ships with four Intel Xeon Gold 5120 processors, each running at 2.2 GHz with 14 cores, and 512 GB of DDR4 registered ECC memory across 16 modules. Organisations running in-memory databases, dense virtual-machine clusters or real-time decision engines can deploy the system immediately without additional configuration.

Enterprise chassis and connectivity

The 3U enclosure provides eight hot-swap 2.5-inch drive bays populated with 400 GB SATA SSDs behind a Dell PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Networking is handled by an Intel X520/I350 daughter card delivering two 1 GbE and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise gives full out-of-band remote management. Redundant 1600 W platinum power supplies and sliding rails with a front bezel simplify rack integration and ongoing service.

Thermal design and power profile

Four 14-core CPUs and 48 populated DIMM slots generate substantial heat, so the R940 uses a high-airflow 3U thermal architecture with redundant fans to maintain stable inlet temperatures under sustained load. The 1600 W platinum supplies operate efficiently at typical utilisation, reducing waste heat and lowering operating cost compared with lower-efficiency units. Acoustic output is managed for data-centre aisles rather than office environments, reflecting the platform's intended deployment in dedicated server rooms.

Questions about this item

What SAS speed does the PERC H730P controller cap in practice?

The PERC H730P controller runs at 12 Gb/s SAS and SATA, so that is the practical ceiling for drive throughput.

What physical space and rails does the 3U chassis need to mount?

The server occupies 3U of rack height and ships with Ready Rails for standard square-hole or round-hole cabinets.

How do I install the CPUs and what step is often missed?

Install each Xeon Gold 5120 into its LGA 3647 socket, then apply thermal paste and seat the heatsink — forgetting the paste is the common error.
